Content management systems or CMS are normally used in the Internet industry. Moreover, content management systems is making it easier to develop a website and it can be also used to support multi-user blogs.

Multi-user blogs are becoming as popular as a CMS, as several administrators realize the numerous advantages of the Web to create and manage their own blog in multiplayer mode. Multiplayer blog is primarily a site that allows people to become authors and have their own section on the site. These authors may contribute to the site in writing, their views and debate. It is also called blogs. Multi-user blogs are free. What’s even more tempting is that the contents of the site can help to boost your ranking in search engines. Apart from a better rating, the owner of the blog can also earn revenue from advertisements placed on the site.

Bloggers can use the content management system to limit the things bloggers can do to the site. On the one hand, CMS could help to limit the amount so that writers can make changes on a site. This is possible by setting the preferred constraints, and permission of the author in the CMS. There are different content management systems available  like WordPress, Joomla, Drupal, and so on. When it comes to multi-user blogs, most people would agree that WordPress is the best open source CMS.

• WordPress is easy to use and very user friendly.
  
• It was created primarily as a blog so there are several versions of blogs and dedicated hosting services.
• There are also several plug-ins and a variety of topics to choose from.

WordPress is capable of supporting an unlimited number of users, making it suitable for multi-user blogs. Now, WordPress uses about 202 million sites.

Another ideal CMS software for multi-user blogs is Movable Type multiplayer. It costs more than a thousand dollars, although there is a limit of 50 people. Unlike WordPress, which can be easily configured, movable type multiplayer can be quite difficult to establish. It publishes a static web page HTML, in contrast to CMS pages, published by WordPress.

I was wrong. I thought that the “trend” is always to buy a VPS (Virtual Private Server, also called Virtual Machine, VM) was over and yet I cannot help but noticed that there are still a lot of people who  still speak so much of the goodness of these solutions to shared hosting when it is no longer enough .

The VPS are nothing more than virtual machines created with different technologies, depending on the needs and the provider you choose, but from the point of view “operations” are real and their dedicated servers are only different in the eyes of the user in name, but with all issues involving the management of a server on the network, from its management.

Users have begun to compare VPS hosting plans with shared and reseller for some time: this led to these solutions because they offer to acquire the ability to manage more domains, to have a control panel other than the one we have seen in most other offers shared hosting and why it usually has a “full customization.” The “merit” is a lot of offers, not managed, they did seem really easy to manage your VPS, if not for the fact that these require knowledge and a management of shared hosting, even professional level, obviously not required. I try to clarify once and for all and then with a series of points about what gives a VPS and shared hosting one thing, trying to emphasize a line of confrontation between the two products:

VPS :

• SSH access to the system
• Operating system chosen by the customer, to be managed in a common server updates
• Ability to host multiple Web sites without limits since the machine is at the customer
• Control Panel of your choice
• Need to perform periodic updates, safety and management system
• Monitoring and optimization of resources by the customer
• Useful for personalization and Web sites that require dedicated resources
• Backup by the client, preferably on the external server (additional cost)
• Shared Hosting / Reseller
• Full management by the web hosting provider
• Optimized for the use of web pages
• Control Panel chosen by the provider
• No specific knowledge required to manage the system

Also suitable to absorb peak loads and important if it is a professional solution with high level.

• Ability to host multiple domains in the case of a product or multi-domain reseller
• Inability to change the system and components supply
• Backup almost always included and automated
• Suitable for any type of website that does not require customization side ‘system, changing the price range.
• ALS determined by contract with the provider
• Shared environment, you still have a breakdown of the machine hw resources

I hope I was able to focus on what are the salient features of the two offers and why a VPS is a solution that is more complex to manage, justifiable only if the customer really needs.

When two years ago we started to talk intensely about cloud computing, you looked at this technology as something very abstract, so that the same hosting provider did not see any reason to start to become interested in something that would come to a finished product after years. So it was not, and even at the expense of those who did not believe it, the cloud services today, is a “race” for many providers  convinced that they can reuse their hardware or their marketing, even with this new product. Many are taking it seriously, with advice and targeted investments, mainly aimed at creating its own private cloud, and not the use of a public cloud, obviously considered too “far” from the property.

Yet there are also opportunities to wonder. A provider of the Indian scene claims to use a solution of a cloud as well-known Indian company, came in first with the reality term cloud services in the Indian  market. The most observant will know who we speak, for others simply search on Google. This is an interesting piece of news, because in fact marks the transition from dedicated server, up to now, seen as the only solution for hosting providers that want to offer shared hosting, the ability to accommodate all its customers on cloud instances, expandable and scalable so as to decrease the load or the customers.

The cloud services today provides everything that you need, with a management certainly greater than that of a dedicated machine. The potential for increasing the resources allocated in real time, including the band, is certainly a feature of interest to those who provide shared hosting or have clients with unpredictable traffic.

The costs are definitely lower, but in this case we are talking about an investment that can make sense only if all its infrastructure migrates in a cloud outside. The choice of a public service for a hosting provider sets conditions of assurance on it that could turn up their noses a lot , but it is clear that the implementation of a solution of much higher costs than private cloud has an initial investment and all hosting providers will not be able to afford this.

The transition from dedicated server to cloud computing will obviously be easier for hosting companies, when they exist standard platforms, then move one instance of a large provider to another will not be a problem and will give technical and economic opportunities that will not be indifferent.

Much of the debate today on the web focuses on the need for infrastructure, dedicated hosting can be quite scalable in terms of web applications that can have a variable number of users.

What does this mean?

Especially in India there is the number of startups growing, and we talk for almost all web applications, social or other things which have their own common denominator and the analysis of data from external sources, third party service API, or the storage of large amounts of information.

PHP is a scripting language that has most enabled the web to grow with the creation of new services and web applications today is no longer the leading choice of web developers. Frameworks like Ruby on Rails has made development faster, but with the demand for different hosting environments.

In this sense web hosting needs are quite different from what we usually read. Many of the people are looking for solutions for the management of a CMS, a community or a portal, more or less growth. Not to mention the requirements that involve an application online that is growing strongly, this is for now only in few cases.

But I am sure that this wave of start-ups and web applications will come. But what are the platforms and languages used? Other than that we find today on many web hosting platforms. PHP is no longer the first scripting language used, the MVC model embodied by Ruby on Rails is one that is popular for the design of web applications with greatly reduced time. Alongside there are other languages like Python , not in first place among the choices, but definitely one of the languages that are considered by several projects.

There are a number of tools that cover the management of services, memcached is a solution commonly used for content caching, while on the front of the DBMS, solutions NoSQL are a must for many startups that want to manage large amounts of data. There are dozens of services worldwide that offer VPS for developers, with preconfigured environment of this type. The implementation of a service that aims to offer these services as a platform, in a perspective of shared hosting service, is completely lacking for now, but the addition of these technologies will go hand in hand with their spread.
online.

Today, I will speak only of some advice on how you can make a better server backup of your own dedicated server or VPS. There is talk of unmanaged server, where the server is put online without any assistance and with a backup policy to be implemented completely at home.

Backup, really needed?

If your server contains only the files of little importance, websites of which you have made changes in years and years, then the answer is no. If you have websites and important files, then you must immediately count the cost of the server that must be added with a backup solution. The budget may be commensurate with real needs, and also varies depending on the frequency with which we want to backup.

The first step, I repeat, is to become aware that without a back up, our service should not go online. In the case of data loss we will not give any chance to get back online in many cases and many have to remain offline for a long time.

What kind of backup?

Run up the data on the same server that provides the service does not make sense , and in fact it is only useful if that backup is then immediately exported elsewhere, on other media. The best choice is to back up your server on another machine or even better on a service dedicated solely to the backup, which in turn has an adequate technical data protection.

If our business is important, it is better to start now to think of the redundant backup across multiple media: an online backup service at a special (sending via FTP or rsync) or through the placement of data on external media such as DVD or our hard drives in the office.

Usually other dedicated servers are chosen to back up several machines online, virtual and physical properties: it is not entirely the best solution, at least not until it is combined with other solutions (media). Better then to think of a dedicated external backup service, to another provider or directly online through one of the many services worldwide that offer backup space. The advantage is that in fact these services in turn provide data security systems and reduce the risk of loss or damage to the integrity of the data.

How often to backup?

Daily, weekly, biweekly or monthly?

All these options have a different charge, as do a daily backup actually means keeping multiple copies of data. Usually a daily backup is very useful for database and dynamic web sites that are updated daily, but of no use if our data is not updated frequently. The weekly backup is usually the intermediate solution, the one chosen most often for web sites and servers that contain a good number of GB of data and must be backed up with a cost, however small.

It often happens that users complain of the arrogance or rudeness of the services of their web hosting providers, usually accusing the Indian providers who seem truly disliked more than those overseas. From experience I can say that it is not so, and it also happens in the U.S. If there are technical staff with a bad day, they can succeed unpleasant ticket, and sound very detached, as is normal, there are people to respond.

What we have tried many times to say is that the dialogue and the approach used with the assistance of its hosting service is almost always determined by the emergence of such problems . Let me give some advice that may be useful for the next time you’ll open a ticket, in different situations.

Downtime, ticket information request : in these cases, it much depends on the type of service, let’s assume you are on shared hosting, domain and web space. Report this downtime, but immediately asking for explanations and complaining about the disruption cannot take away the problem. I almost always have a service provider monitoring and they probably are already working on the problem, but to answer and inform the customer of all is a bit more complicated than you might think. This kind of ticket does nothing but delay the response to obtain explanations or altered, more so in smaller companies, where technicians are alternated between ticket and challenge. Better to ask about downtime and reserve at a later date to discuss the details, including any reimbursements provided by the SLA.

Unanticipated changes : not all hosting providers allow queries about changing some settings, the more so about our script. From experience many hosting providers are also inclined to grant modifications or inspections not covered by the contract, but always make sure that this behavior is or is not a favor, and especially what are the requirements to be feasible contract.

Domains and mailboxes : two of the most popular services when it comes to tickets, users often forget or fail to include important details useful information for a quick resolution of the problem. Writing “mail does not work” is unfortunately a lack of information and not very helpful for certain services, then try to include a precise description of the problem, adding examples. With these two services, it is very easy to explain vague, especially if you are inexperienced, you ask for details. It is quite normal, and most importantly it is critical to the resolution.

Upgrade and trade demands : loading problems often end with a proposal for a new plan or upgrade to a dedicated server from the provider. Before assessing whether this is or is not excessive, ask for a proper technical explanation of the problem and the solution, some customers often accuse the providers who want to sell a superior solution if technical problems are not resolved. An explanation and analysis technique can be useful to ask a further opinion and get useful information with which to compare.

Avoid threats of publishing information on websites, a practice that  is quite wrong and does not lead to anything good, so do not threaten the publication of the story on portals, blogs and industry. This almost never helps to solve the problem or unlock the situation. Narrating the positive or negative experience in any case will be a next step, but certainly not helpful during the dialogue with the service.

The technique of virtualization is to create a virtual version of a hardware resource normally provided physically, in particular the x86 virtualization is the creation of a virtual version of a resource belonging to a system with x86 architecture. Any hardware or software resource can be virtualized, so you can have virtual versions of operating systems, memory, disk.

This technique then allows the execution of one or more operating systems and associated software on a single computer without rebooting the system, and with the advantage of creating a secure environment where they are monitored and carry out the instructions of the virtual system.

Virtualization is made possible by the excessive size of the hardware architectures in use today than those that are normal and most common uses of computers. The uses of virtualization is probably the most popular operating system virtualization to create virtual servers for test server to support the development, or creating websites. In the context of virtualization, there are two different systems, host and guest. The host system is the system that is running a virtualization software that creates a high level the different virtual machines, which function as if they were normal programs, communicating with the hardware only indirectly, through virtualization software that works at low level. The operating systems running within each virtual machine guest are defined.

Types of Virtualization

It is possible to distinguish different types of virtualization, depending on how you run the virtual system. In particular, it distinguishes between:

Full virtualization also known as native : The characteristic of this mode is the presence of a hypervisor that implements the separation between the host system and the physical hardware of the machine, creating an insulation between the two domains. It is also identified as virtualization software, and a well-known example is the implementation of VirtualBox;

Paravirtualization : The control software exports an API to the hypervisor, which allows access to different hardware resources to the host system. This mode is implemented by the KVM virtualization;

Emulation : The control of software emulates the underlying hardware for the host system. This type of virtualization is slower than the other two, since all operations at the level of machine language must be translated by the instruction format of the host system to the guest system.

The virtual extensions from Intel and AMD

Intel and AMD have independently developed virtualization extensions to the x86 architecture, natively integrated in the set of instructions from their CPU, and these extensions are not fully compatible with each other, but support roughly the same instructions. The added value of this selection technique is that the Intel / AMD with support for these extensions allow for virtualization management in hardware, resulting in gains in performance, because a virtual machine that has to emulate a hardware for a host operating system with access to this set of instructions on the CPU, will reduce the computational load on the CPU and no longer having to emulate the entire system in software.

The virtualization extensions developed by Intel for the x86 32-bit (IA-32) and 64-bit (EM64T) is available on all Pentium 4 6×2, Pentium D 9×0, Xeon 7xxx, Core Duo and Core 2 Duo except for the T5200, T5500, E4300, E4400, E4500 and E4600.

AMD processors that use the Socket AM2, Socket S1, and Socket F AMD Virtualization support, including the Athlon 64, Turion 64 and Opteron.

KVM and QEMU Virtualization to 100% in Linux

KVM (Kernel-based Virtual Machine) is open source software, which allows for a full virtualization solution for Linux on x86 hardware that supports virtualization extensions such as Intel VT or AMD-V.

Each virtual machine has its own private virtualized hardware, such as network card, disk, graphics card, without going to touch the guest system. KVM is a kernel module, in a separate part that acts as a core infrastructure virtualization, and then the specific part for the guest of Intel or AMD CPU; modules are intel.ko-kvm and kvm-amd.ko . The module includes a char driver who is responsible for directing the control of I/O from the guest kernel to the host system.

The KVM package includes a modified version of QEMU which makes use of this form. QEMU is a processor emulator that is capable of emulating several hardware architectures, including x86, x86_64, ARM, SPARC, PowerPC, and MIPS.

The system hardware is emulated guest dynamically by examining the code executed within the virtual machine and translate it into instructions comprehensible to the guest machine. Modified QEMU is much faster and with higher performance, because of the KVM uses processor extensions for virtualization and the original emulates the ioctl.

The host, however, is bound to the x86, x86_64 and PowerPC. In the case of the x86 architecture there is an accelerator (kqemu) able to avoid the dynamic translation of instructions, allowing you to achieve performance that is around 30-50% of those of the guest.

Using KVM, one can have multiple virtual machines running simultaneously. The kernel component of KVM is included in mainline Linux kernel since 2.6.20.

Preparing for Installation of KVM

From all this it is clear that KVM is necessary to run the CPU support virtualization natively. You can test whether there is support in a simple way from the console with the command

root @ User-VirtualBox: ~ # egrep-c ‘(vmx | svm)’ / proc / cpuinfo

If the answer is 0 means that the CPU does not support hardware virtualization, but if the answer is a virtualization is supported , but you must verify that the BIOS option is enabled for virtualization or not. Some computers have disabled the possibility to use the virtualization extensions of the processor, in this case, go into the BIOS and enable the use.

Installing KVM requires some precautions, especially for the amount of memory that will be allocated to the host system. Indeed, there is a limit to the amount of memory you can dedicate to the virtual system, and adopted at a maximum of 2 GB by installing a 32-bit kernel, over 2 GB with a 64-bit kernel.

This choice implies, therefore a 64-bit virtual machines can accommodate 64-bit and 32 bit, instead of a 32-bit system is limited to only being able to accommodate 32-bit virtual machines. Obviously a 64-bit kernel requires a processor from the same surface area, which can be verified very simply with the command:

User-root @ server1: ~ # grep ‘lm’ / proc / cpuinfo

lm stands for long if this command mode does not provide any response means that the CPU is 64 bit. Instead, to verify that you are running a 64-bit kernel can use a command like the classic;

User-root @ server1: ~ # uname-m

the result indicates the type of processor, in particular, the term x86_64 from information that you are using a 64-bit kernel, while the abbreviations i386, i486, i586 or i686, indicate that you are using a 32-bit kernel .

Installing KVM

Installing Ubuntu in a 10.10, as always, is helped by magical apitude, which will install and prepare everything you need:

User-root @ server1: ~ # apt-get install libvirt-bin kvm qemu-ubuntu-vm-builder bridge-utils virt-viewer

Specifically, the packages that are installed with this process are described below:

• qemu-kvm is the backend, that is the real core that creates and manages virtual machines;

• libvirt-bin daemon provides libvirtd required to administer instances of using kvm and qemu libvirt ubuntu-vm-builder is a command line tool, very powerful, used for creating virtual machines;

• bridge-utils provides a bridge between a network and the virtual machine to allow communication with the real external world;

• virt-viewer, you see instances of virtual machines

After completing the installation process it is necessary to have an image of the host system to boot. To create an image, simply use the command qemu-img that is in the directory / usr / local / kvm / bin /:

User-root @ server1: ~ # / usr / local / kvm / bin / qemu-img create-f qcow
filename.img 3000M

after which you can launch and use QEMU:

User-root @ server1: ~ # / usr / local / kvm / bin / qemu

In conclusion

Virtualization is a very complex and extensive that it cannot be exhausted in a few lines. We have just taken a little ‘dust from one topic that often scares in an excessive way, because it is relatively young, and because often, virtualization is introduced as a concept, we speak of the creation of virtual systems, but do not expose those added values and benefits of using a virtual system in daily use.

The return on investment is due to the use of a virtual server, thanks to excessive size of current systems than those that are with the daily workload. Virtualization allows you to use hardware resources more efficiently, to create virtual networks internal to a single computer, to test software, attacks and their methods of defense in a safe environment without compromising the guest.

Also the possibility to migrate a virtual machine from one guest to another, in a simple way you can start services that would normally take longer because of the need to find a dedicated server hardware, thus the mobility of users and the portability achieve greater added value.

I personally think that the ability to run applications and systems are no longer supported, developed for different hardware and thus have no need for a high number of physical servers in addition to the charges involve in a significant investment in space, and still being able to eliminate the dual boot and to use as Windows and Linux simultaneously on the desktop and laptop to communicate the two systems as if they were on a real network, has paid off all efforts to push virtualization to the degree of maturity that has reached today.

When we purchase a product or service that requires a significant investment, it is essential to know in depth the characteristics or properties, if you have a product, and the advantages and security provided if a service.

When it comes to data center, there are multiple factors to consider:

First large data storage capacity. Not only that, but good exchange rate for the same. If we shut down  the server, but far from databases, the set speed will suffer.

The physical data center runs on electricity. It should have assured electricity even in disaster conditions (cuts supply network, fires, floods, etc.). It should not just have a efficient UPS but also the authentic electric generators to ensure supply.

Backups of course. The data is stored redundantly and must be accessible in a transparent manner if a database or server goes down.

The redundancy is applicable not only to the above, but for all the physical devices involved in the management and transmission of data.

Very important: We not only have to think about security and communications software , we must also think about good physical security for all equipment and wiring.

A data center that does not have a professional team, or have 24/7 support, the proper operation of the service is not very reliable. The provider should maintain and update the software (this task must be fully supported by this team). The provider must be available to customers to solve any problems that arise.

Increasingly, data centers are concerned to comply with the recommendations within the scope of  “Green IT” and this will benefit customers to lower energy costs through efficiency.

Finally, ensure the financial solvency of the company that provides service and … before you sign the contract rather read the Terms of Service and the fine print.

How to get all this information is easy to imagine. Almost always, gather this data from the service provider.

The traditional business applications are always very complicated and expensive, to the point that needs of hardware and software necessary for their implementation are such that it cannot be met. Moreover, the complexity of some software platforms requires specially trained personnel for installation, configuration, testing, implementation and upgrade. The costs to support this complexity can be unaffordable for small and medium enterprises.

On the other hand, companies need to use their own resources, and safety, and also the need to use an experimental platform hardware or software, or proprietary, and thus cannot be shared with other companies, can make all the infrastructure necessary to take network under control and did not entrust the management of external services, not always easy to monitor. Thus the need to understand the distinction between Cloud Services and data center colocation was born, and where to start and finish each others advantages and disadvantages, in order to make the choice to be the best compromise between cost, quality of service, and real needs of end users.

Cloud Services

The term Cloud Services came with bullying in recent years in most discussion related to the computer world, becoming the main actor, without that most of the experts know what it is.

We have a lot of  articles on our blog that explains a lot of things related to Cloud Services and all types attached to it.

The term Cloud Services is a set of technologies that allow the use of hardware resources such as CPUs and disks, or software distributed in remote, in other words: the ability to access services and data via internet without any information infrastructure that keeps them and makes them work.

Cloud Services allows you to do all the traditional activities that concern the use of a PC, except that the software is no longer performed locally, for example, to open a text document, instead of clicking the icon editor and making the modifications we will click on browser and enter a web address from which a text editor application can be used. The same operating system, desktop, folders and files will be displayed and used as if they were on local pc, but this is only an abstraction of reality, as it will be installed in a physically secure location, remote, within a set of infrastructure, data center, equipped with high-performance servers that store the data.

Typically, the graphical representations of the Internet, represent the network as a cloud they are attached to individual host or service provider. Cloud Services is what is in the cloud, without the end user, who needs to know how it is actually structured.

Cloud computing, in technical terms, is then offered as a series of virtual machines that allow you to spread the load and balance the resources between them, being able to add resources only when these are necessary. The cloud of ESDS for example, allows the creation of virtual instances on demand, only when these are really necessary, and this approach has led to a number of uses that favor cloud services for online high-traffic area, with sudden bursts of Use .

Pros And Cons Of Cloud Computing

• Architecture of this type has advantages such as lower costs, as software in the cloud “significantly reduces the investment to do than buying licenses to install the software locally;
• lower support costs, since the update to the latest release is without a dedicated IT department maintains, updates and installing new software;
• reduced risks relating to bugs and attacks, as data security becomes an issue of the hosting provider;
• access to services at any time, any place, without the need to carry, portable devices such as smart phones, tablet, XPAD, or removable storage;
• The advantages are obvious, but at the same time, the adoption of such a technological solution for the end user has disadvantages that must be taken into account.

Access to the cloud is online and you need a reliable and fast connection, and one that also includes a subscription, and then the choice of provider must be made with caution, as the provider will be responsible indirectly for the productivity of their employment and security of their data. A situation of failure of network access, or inaccessibility of the provider, can lead to loss of use of services, and lack of access to their data remotely, resulting in suspension of work activities, having moved all in remote, we have no control over what happens, I can actually know how data will be processed, or whether they will be used without consent and notice. A secure solution would be the replication of some services, and all the data locally, with the consequent need for periodic synchronization and increased costs.

Cloud infrastructure solutions are also always shared , in terms of resources, which means that the user may incur risks of sharing data with other users or to share the same problems that plague the entire platform.

Usually the Cloud Services provide for contracts with very few fixed costs, most of the billing service is on-demand, when the customer starts using the service and creates the first instances in the cloud: the same storage happens, in optical cloud, this is billed according to consumption, and the customer should not purchase a cut of space, as it is the case for a normal server.

Colocation And Dedicated Server Rental

The colocation service allows you to locate one or more servers, network devices, or storage of customer property in a single data center, their dense structures and spaces of the same way as a hotel room for people, these devices are also hosted a variety of related service provider (network and telecommunications), with a reduced cost and complexity for end users. A colocation center is a special type of data center and systems are placed inside a standard rack cabinet in the structures used by the provider.

The co-location provides an effective and safe way to host services with related equipment. The server is owned by the customer, but it is also possible to rent a server from the colocation service provider. The installation, setup and maintenance are charged to the customer, who has a difference of architecture cloud control hardware and software, and can be accessed in a manner similar to how you access a website.

• Colocation solutions are offered either in a shared environment, mostly, and the provider takes care of backup and disaster recovery solutions in demanding environments for providing electricity for environmental systems and levels of physical security. A colocation provider usually provides:
• space, with different sizes and slot within the rack;
• bandwidth, dedicated or shared;
• power, which can be single or redundant with remote control;
• Access to and support during office hours, access and support H24, H24, or with access badges;
• IP addresses, IPv4 and / or IPv6;
• any managed care services, with the support of technical staff in the data center, either locally or remotely;

In the final analysis, particular attention in selecting the data center should be given, since it must represent the structure and the ideal environment to host the server , observing certain requirements in order to provide suitable infrastructure for companies that need a customized solution for the implementation of web-based services, and that in particular need to use proprietary hardware.

The colocation and dedicated server rental solutions are still preferred by customers who want to maintain complete control over their data, preventing external access or problems to the whole cloud, could endanger their services. This is especially true in business environments where process information is critical, especially in the context of Public Administration, where it is unthinkable to entrust their data to an external manager.

Cloud Services And Your Server Colocation

What can be the Cloud Services management with respect to a colocation data center, and vice versa, what are advantages and disadvantages.

Much depends on the kind of vision we have for the business, and also how you will organize it. Many companies are wary of Cloud Services, because of its “without control” structure, and therefore it is strictly linked to the impossibility of having specific well-defined and clear architecture of cloud. But this happens particularly for large companies, which in principle have the economic resources to cope with the investment in a complex IT infrastructure, efficient and scalable.

Small businesses that may require large computational resources are faced with the problem of costs, and therefore are more likely to accept a cloud solution.

If your company has financial resources to invest in the IT department, which is always less likely in view of the crisis still exists, Cloud Services may be a test solution, but nothing more, in case you should have the resources to invest in IT Infrastructure, using the co-location, to overcome problems of space and maintenance of the physical server environments.

Cloud Services, and its continued evolution is certainly a desirable solution for companies that have few resources to invest in the architecture of the network and are willing to greater flexibility , especially in the context of a service due to connection problems, the provider network may degrade.

The colocation is suitable for companies who need to expand their hardware without losing the current level of security, and this is an effective way for companies to manage the company’s software securely from anywhere in the world.

To be more specific, the world of online services, from web hosting to the online applications, can greatly benefit from Cloud Services, especially if you do not want to initially invest in the purchase of their hardware resources: however, this has a negative return in terms of customization, often Cloud Services environments, totally virtual and dispersed data centers abroad, do not allow for action at all levels of its infrastructure, so they cannot meet the demands of some customers.

The choice of a Cloud Services service, in this context, it is preferable when you are faced with resource consumption variables from month to month, with the need to make available its online service to thousands of people, in a few days, and with a zero investment in terms of hardware.

The co-location, as well as direct hire dedicated servers, is now the leading solution for those who must maintain tight control over their data: this also means the ability to create own private cloud, in order to enjoy the benefits of maintaining cloud however, control over infrastructure.

With the growth of the value of clouds for some IT solutions providers are beginning to take an interest in what exactly it meant. In the end, many of you have long offered clients to use host-applications, which, in essence, cloud services are under another name.

So you already know what are the benefits that are provided by cloud computing services to your customers: a small initial capital costs, or complete absence, pay only the actual services received, scalability and flexibility. For you, the main advantages of cloud services are a constant revenue stream, deep penetration in the business of clients and flexibility to tailor services to customer needs.

So if you have some time provide Hosted Exchange services with or related to backup and restore data, you are completely forgivable to ignore the talk about clouds as the next hype in the IT industry. Or unforgivable?

Enough to have in its arsenal, one or two services such as SaaS, although they could well help you prepare for the era of cloud services. Looking to the future, customers will increasingly move their infrastructure into the cloud. And if all that you can offer, is the e-mail host system, you face the loss of customers.

Since virtualization, private clouds and services based on public clouds every day are becoming more popular. IT has a long history of adaptations and innovations, and cloud is a important chapter in this story. If you skip this chapter, it can have fatal consequences for your business.

Large corporations such as Verizon and Google, end users are bombarded with advertisements on its cloud products. As this onslaught of more and more customers will be prepared to cloud computing and would like to have more services.

Fortunately for solution providers, you have plenty of options to create a full set of cloud services. Let’s say you have to offer Hosted services through Exchange. What can you supplement them? It makes sense to explore other products Hosted on Microsoft, such as server, database and maintenance of desktop systems, to create a cloud menu.

Of course, you are not limited to products of Microsoft, Cisco and Dell. You and all the solutions provider should also not be overly suspicious of large corporations. In particular, although Microsoft has achieved record sales through the channel, the manufacturer has caused some confusion among its partners on their role in providing cloud services, such as Azure and BPOS. However, Microsoft’s strategy in connection with the clouds deserves a separate article.

Solutions providers should also pay attention to host the infrastructure and services such as “platform as a service” (PaaS), as well as to private cloud using virtualization technology and reminding the public clouds, which allow you to take advantage of the cloud environment inside the network perimeter.

Many manufacturers also offer in addition to its virtual cloud product technical support. This means that you can give it to function manufacturer partners and focus on growing your business.

So when it comes to clouds, then, yes, there is no shortage of publicity. But this does not mean that solutions providers cannot simply ignore it and do its routine. Clouds are a source of change, and therefore require that providers of solutions once again adjusted to the ongoing large-scale shifts in the industry.
