Cloud computing represents a new paradigm for understanding the technological services. The versatility of the infrastructure and model-based platforms enable cloud infrastructure managers to expand its catalog of current services and add new. An example of new services developed from the Cloud Computing IaaS (Infrastructure as a Service) model would be the RAAS service (Recovery as a Sevice or Disaster Recovery Services). This service offers a replication and disaster recovery based cloud that keeps a copy of their systems and information in a second location as a contingency platform disaster or unavailability of the platform housed in the original location.
Backup system and application services are having a good acceptance since they are a flexible solution that adapts to the needs of each client and to guarantee Times Reduction Objectives (RTO) and recovery (RPO) by automating tasks and Replication recovery. Recovery Point Objective (RPO) can be aligned to the business needs of the client, which allows adapting the service to the objectives defined in the Corporate Business Continuity Plan of each company. Among the main benefits of a service, Disaster Recovery emphasizes the ability to protect business-critical systems, including the recovery of operating systems (Windows and Linux) and application recovery, thereby reducing the risk and costs associated with the unavailability of information.
Being hosted in these safe accommodation geographically separated from the original, you get increased security (floods, terrorism, …), although it should be noted that the contingency accommodation must meet the same legal requirements. Another key benefit of disaster recovery is based on cloud hosting scalability when defining the scope in terms of the services to be protected. This allows to adapt to any conditions included in the corporate contingency plan. The client can start protecting those most critical servers exclusively for your business to go further or even migrating additional services to complement existing backup system in other sites.
RAAS in some ways represents an evolution of traditional replication technologies (DRS), but be a service developed in Cloud Computing IaaS mode allows significant cost savings, as it eliminates the need to purchase hardware, book space, allocate human resources to the preparation and execution of tests, etc.. Paying only for the services used. Operation of a Disaster Recovery service Although the operation of the Disaster Recovery services may vary depending on the provider, you can generally extend the protection from physical or virtual machines to different virtual platform.
Bear in mind that while it is possible to replicate physical servers, few providers support it, and if it makes the physical servers support at source on servers in the datacenter contingency. virtualization (and the fact that replication is done from the hypervisor) offers advantages that can be applied to business continuity and disaster recovery, including: statewide encapsulation of a virtual machine (memory, disk images, E / S, and the status of the device). Encapsulation allows the state of a virtual machine that is stored in a file. Save the state of a virtual machine to a file that allows the transfer of an entire virtual machine to another host. Hardware independence eliminates the need for a complete replica of hardware in the recovery site.
This eliminates the cost of purchasing and maintaining a system that is inactive until a disaster occurs. Hardware independence allows an image of the protected site system to boot from the disc on the recovery site in minutes instead of days. This phase will determine the replication mechanisms suitable for each application (hypervisor, data backup, mechanisms of the application), consistency that is minimum necessary for all applications to launch its services in the contingency site (crash, file, application), and the RTO can be expected throughout the plan from the applications and data volume comprising the protected platform. During the second phase, it will proceed to the installation and commissioning of the platform contingency.
This phase will take place when the replication settings hypervisor level and cabin, and creating scripts and reconfigurations required (network, nomenclature, DNS) for the proper functioning of the recovery plan. Then proceed to the execution of the first tests of the RTO recovery and establishment of reference and the creation of a Disaster Recovery Plan. It is a consensus document on establishing the protocol for the formal declaration of a disaster and the activation procedure contingency site.
In the third and final phase, it will be the management of the service. In this phase periodic testing to ensure the proper functioning of the service is done. One advantage of using virtualization in the contingency site is ease to perform recovery drills without affecting the protected site. This feature reduces the risk of failure recovery when this is necessary. During the test simulates the full recovery of services and any discrepancy is detected between the recovery plan and the changes that have been made at the protected site. This recovery plan is updated. Periodic tests help to detect changes in the RTO and take corrective action.
The Christmas season is coming, the people around the world will start with the preparations, all the online stores will start offering discounts on their products online, registering the highest number of annual sales.
During this period, all owners of an online store, call for the audits required to prepare for Christmas period. This article will give some tips to be prepared to handle a larger number of orders, requests and demands within your own online business, it is obviously too late to hand updates to the code of your e-commerce, as well as to prohibit the possibility of changing critical components, which are not tested in this period.
Upgrading The Server And Your Web Hosting Plan
Depending on your e-commerce store which would be hosted on shared hosting or within a dedicated solution, it is useful to take some precautions:
Check your plan and upgrades: If we launch a promotion that can bring a greater number of visits, then it’s time to even think of expanding its shared hosting plan. In this case, we contact the provider to request a change to a higher priced plan, specifying the fact that it takes more resources for the website, and then the plan itself should be moved into a more powerful machine.
Troubleshooting the ISP: To find your main domain, website or e-commerce locked in the month of December is not a good news, we see that any faults with your ISP, from the perspective of technical and commercial, are resolved. Needless to require version upgrades or changes to the plan webhosting at this time, the only requirement may be a change and a server upgrade.
Upgrading your Dedicated Server: If your e-commerce is hosted on a dedicated server, it would be useful to contact your service provider for the adjournment of the same. If they are not already the best performance, it is unthinkable to go to support an increase in visits. Increasing the RAM could be the necessary first step, followed by a reconfiguration and tuning your server, something we see in a few lines.
Cloud Computing Or Cloud Hosting: If we do not have the possibility to increase the resources of our area of shared hosting or on our dedicated server, then the best solution is to include the use of an instance of Cloud Computing effective only for the month of December, or at least only for the period in which we expect to be able to have a greater number of visits. In this case ESDS offers cloud computing solutions with pricing that it can be used for the required time.
You ignore the discourse of performance on the ISP side, it is important to understand if you (are) really ready to face an increase in visits with the configuration of server or instance of cloud computing. The first thing to do if we are not experts, is to contact your ISP or service ‘system to ask a tuning of the server.
What we need to verify exactly:
Apache : We are going to verify the configuration and memory consumption
Nginx : If we use this webserver, we just go to prepare a configuration tailored for our system, basic already get superior performance with Apache
MySQL : The use of tools to identify the problems of MySQL will save you a lot of time.
Finally, after working on our webserver, it is essential that an e-commerce website takes very little time for opening pages, first check which ones are current through one of the many online tools, we recommend PageSpeed Tool By Google.
Here we can get some information about our web site, an acceptable speed should never go more than 1.5 seconds to open, but we talk already about a very high result. To get further information, it is necessary to use Google Webmaster Tool, which gives an indication of how fast our site is, compared to all those tracked by Google.
Once you understand that the speed of the pages is not acceptable, there are several solutions that can be used. First we have to see if our e-commerce platform allows you to do caching, images in all statistical components. Solutions such as Magento or OsCommerce and have these options and you need to identify the best plugin and put it in production, but this is a change that could present problems so it should be applied at night, checking operation.
Optimizing your site must begin with the classic rules:
There are dozens of guides on the net. We will definitely prepare further test to check the speed of loading. We can think of to use the handy YSlow, which is a plugin for Firefox, or Chrome’s console directly. It will show the loading times of the individual components of the page.
Our Forum community is available for any further information. You can simply open a new topic!!
When choosing a platform for the hosting of your website, you will want to be assured that your website will be able to access sufficient resources to ensure that it is able to run stable so that no downtime is caused because of a lack of system resources. ESDS Cloud Hosting has been designed to be scalable by providing you with access on-tap to the resources that your virtual machines require; with traditional web hosting plan designs you have had to upgrade to the next available web hosting package if you were running low on one particular resource, whereas with a cloud virtual server you can elect to upgrade the individual resources of your virtual machines as they begin to run low so that you are only ever paying for what you need. It is the ability to upgrade individual resources as your needs dictate that makes cloud web hosting scalable because it means that your web hosting environment can grow with your website and there will never really be any limitations as to the level to which you can scale your cloud virtual machines because resources are so easy to come by in the cloud. When seeking a scalable cloud hosting service you should look for services that use this pay-per-use hosting model because these are often built around a self-scaling cloud model that will provide you with a cost effective solution.
As a website grows, it is going to be receiving more and more visitors every month and with this will come an increased load on the server hosting the website because there will be more people doing more things on the website at the same time and as a result of this there will be an increased number of requests for the server to deal with. With a scalable web hosting environment you will be able to grow the resources of your server to match the pace of growth of your website so that you are never having to worry about downtime being caused by a lack of resources; this removes the limitation of other web hosting environments with which you would have to upgrade to a different type of web hosting when you had exhausted all available resources opportunities.
The cloud can aid the growth of a website by providing a dynamic dedicated environment in which you can install the applications and services that you see as necessary for the development of your website that wouldn’t necessarily be available on other web hosting platforms. Cloud virtual machines can take the form of Windows servers and Linux servers so that there is always a platform suitable for all needs; on here you can install whatever you want, such as support for ASP.NET websites or MySQL databases. With the dedicated environment of a virtual server mimicking that of a dedicated server, you can create a secure environment with the use of third-party tools and SSL certificates to prove to your visitors that any information that they enter into your website is going to be kept safe. Finally, the reliability that a cloud server can offer is near 100% guaranteed with most web hosting companies so that your website will always be accessible and to reduce the chances of revenue being lost because your website can’t be accessed.
One solution for websites that are unable to predict their future traffic loads is auto-scaling because this will assign additional resources to virtual machines for the short term whilst being placed under a load spike or similar situations. You will never be certain of the resources being used on your cloud virtual machines at any point in time unless you are using specialist monitoring software and so it will be helpful for many businesses to have a solution in place that will take care of increasing resources for them; these additional resources will then be returned to the central pool once the load on your cloud VMs resides, but you will still have the option to reassign these resources permanently if you feel that the increased load on your virtual machines is going to be sustained for a long period of time.
The Cloud Computing is not a technology but a concept that can be defined as a computing model in which processing of data and programs happens somewhere on the internet and can be accessed from anywhere in the world.
Cloud Hosting is a service which is offered by a lot of service providers, in which multiple servers are used for high processing capacity, high availability, which are connected to a storage drive (cloud storage).
From Cloud Hosting Infrastructure, you can uniquely allocate the computing resources to create a Cloud.
Each cloud server is a virtual server which is using the resources of an exclusive and independent server which has the same physical equipments.
In all of the servers, there is always a physical server operating on reserve. This server will be activated automatically if a problem occurs on a physical server’s assets. The cloud server in existing physical server that has the problem will be automatically transferred to the physical server backup, ensuring high service availability. This fast switching is possible because all data of all servers are stored in Storage.
This infrastructure enables companies of any size to make use of cloud computing, high availability, ease of connectivity and low initial investment.
Features and Benefits
1. Scalability Of Computing Resources
The architecture of cloud server lets you allocate or deallocate computing resources like processing power and memory for simple and fast operating, and in some cases without the need to reboot the operating system.
And when you need a computational resource such as memory or processing that is not available on the physical server, migrating to another server will be held at the time of the restart.
Note: Changing disk space on Windows and reducing disk space on Linux requires you to reinstall your operating system.
2. High Availability
Besides the scalability of computing resources, the architecture performs dynamic relocation of cloud server to another cloud server if there is a fault.
Every technology employed in the cloud server is to ensure that services are always active as long as possible. The time for dynamic re-allocation is equivalent to the time of the restart.
3. Exclusive Use Of Resources
To ensure server performance cloud server contracted processing capacity, memory and disk space are allocated exclusively, making use of shared servers.
To ensure scalability and high availability of services, the only form of service used is the shared disk subsystem (Cloud Storage).
4. Costs Proportional To The Computational Resource
Another element generated by differential Cloud Computing is the possibility of hiring computational resources for exclusive use, with features of a dedicated server at a cost proportional to the computing capacity contracted.
Can be used with:
Everyone knows that there is no way to guarantee total safety in any area of our lives, this also applies on IT services.
The dedicated web hosting services have high levels of security, using modern technologies, especially with rigid procedures and a highly qualified team to ensure the tranquillity of your business.
Professionals who have not paid attention to the concept should develop strategies for lost time.
Many IT professionals are well prepared for the continuous advancement of systems and infrastructures based on the concept of cloud computing. Although it is understandable that during the year 2011-2012 this ignorance can be a limiting factor for the career.
Many of these professionals still view cloud computing as a term of fashion and have not given much attention. For some time the concept was really fashionable, but cloud computing has entered into another level. The companies already see the model as potential leverage infrastructure and business environment to reduce costs. In addition, many have gone on virtualization, considered a key step before implementing the cloud.
For professionals who want to recover lost time, here are some suggestions for using cloud computing services to leverage the career.
1 – Focus On Education
In that case, you should start from the basics, how to understand the differences in terms of cloud infrastructure, platform and software as well as how and when to use.
2 – Create A Cloud Computing Strategy
Create a personal strategy that takes the work ahead for updates and be proactive about the next technological steps from your employer. How to create a strategy? Including studies and plans on cloud computing in every aspect of technology resources, including the thinking of business cases, road maps and budgets. It’s good to not to forget, however, political issues involving resources: the strategy must include participation from other areas of the company to reduce political risks.
3 – Encourage Experimentation
One of the most effective ways to stimulate the use of infrastructure as a service (IaaS) or platform as a service (PaaS) is to create prototypes that everyone understands the value that technology can (or cannot) bring. Extract the maximum information from these experiments to review the planning for cloud.
The shared cloud is designed to provide individuals and small businesses that have fairly simple requirements with an affordable way in which they can enter the cloud. With the shared cloud you can specify the resources of your individual virtual machines so that each VM is designed to meet its usage precisely; the eNlight platform from ESDS encourages this by providing you with a control panel that allows you to specify precise resource units during the VM creation process so that you will only ever be paying for the resources that you want or are using and nothing more. Resource wastage can be a big issue for businesses when they have to choose pre-defined cloud hosting plans because more often than not there will be certain resources that they aren’t using to their full potential; for web hosting companies resource wastage can represent a failure to assist their customers in having their needs met in full and by offering to allow customers to choose what they’d like to see from their cloud virtual machines, hosting companies can guarantee that businesses have a platform on which their needs can be met in full.
Although the shared cloud hosts many users, most cloud platforms can guarantee up to 100% uptime because the design of the cloud ensures that hardware and network failure can’t impact on the performance or operation of the cloud as a whole. Even though individual servers in the cluster can fail, virtual machines are often hosted across several servers in the cloud so that additional resources can be located on other hosting nodes if one of the servers that a VM rely on crashes. Storage responsibilities are taken care of by central SAN (Storage Area Network) arrays to provide the highest level of data security possible and if any issues occur here, data is backed up across several hard drives so that data loss is pretty much impossible.
Using the ESDS eNlight platform as an example, you can expect to see the following benefits when using a shared cloud solution:
Private clouds cost a lot to setup and run because of the amount of hardware that forms the basis of this environment and the manpower that is necessary to achieve this. Larger enterprises are the target audience for private cloud hosting because this is the only group that would be able to afford such a vast hosting infrastructure and at the same time only larger businesses with high volumes of customers will have the ability to make full use of what a private cloud is going to be able to offer them. ESDS can provide you with the full set of technologies required to run a private cloud, along with the support necessary to run the infrastructure; even though you may have your own IT support team, it will be more beneficial for your business to use ESDS for support of your private cloud because our staff have developed and have full knowledge of the workings of the eNlight platform.
The private cloud is designed to offer the following benefits to larger businesses:
The shared cloud and private cloud are aimed at two different audiences: shared cloud for small businesses, the private cloud for larger businesses. ESDS believes in offering a hosting service that can meet the needs of any users: individuals and businesses; the choice between the two different types of cloud is one that is going to be based on your needs and precise budget. If you are unsure of how eNlight cloud hosting either in a shared or private environment can benefit you, contact the 24×7 ESDS support team today for advice on what will suit your requirements best.
The provisioning of virtual machines and resources for these has been increased dramatically with the introduction of the eNlight cloud, therefore reducing the time that they a business will have to wait to add additional capacity to its IT infrastructure. eNlight users are provided with a web-based control panel through which they can control their entire cloud hosting experience; it is quite normal for a website to require extra resources as it grows and by choosing an eNlight virtual machine, a webmaster can order additional resources when they need them – these resources will be provisioned to the virtual machine immediately upon completion of the order, with no downtime to talk of.
The eNlight platform from ESDS works automatically to provide clients with the best level of service achievable. ESDS has a 24×7 support team that is available to assist you with your cloud hosting service at any time of the day, but all virtual machine and additional resource orders are taken care of by our automated billing and platform system so that you are allocated your order once you have completed the checkout process. ESDS also offers a range of private
eNlight is a form of shared (or public) cloud hosting, a term which means that you are sharing the cloud as a whole with other users. This provides benefits as it means that ESDS will provide you with full support, whilst you can choose between Windows and Linux OS templates for your virtual machines. Shared cloud hosting is an affordable solution and is a good point at which anyone seeking cloud hosting can begin. ESDS also provides a range of private cloud hosting products for businesses with complex requirements – dedicated servers can also be purchased if you are in need of a dedicated hardware solution.
The issue with existing cloud server platforms is that users are often left with idle resources that they have had to pay before because they could only choose from a set of pre-defined cloud hosting plans, but they have absolutely no need for these resources. Idle resources are a waste of money for cloud clients and for web hosting companies they represent a lack of ability to meet customer’s needs in all respects.
With eNlight cloud hosting you can choose the specific resource allocations that you would like to begin with; as you are charged per unit, you will only be charged for the precise amount of resources that you have purchased and this will put you in a position where you are only paying for what you need. You can then increase the resources allocated to your virtual machines as the demand on your website increases and your virtual machines are put under a greater load so that you have full control over how your servers before and your expenditure at every stage. eNlight also has an auto-scaling feature built-in that you can use to automatically scale the resources of your virtual machines when they are suffering load spikes, doing so guarantees that your virtual machines will never crash due to lack of resources and you can put a cap on how much you are billed by using this method.
The clustered nature of the cloud makes managing a cloud an easy task for server administrators because all aspects of a single cloud can be managed from a single interface. With the virtual machines in an eNlight cloud being distributed across multiple servers in the cloud in order to provide the highest level of performance obtainable, it is important for server administrators to be able to manage every server in the cloud from a single location to ensure that everything continues to be synchronized and work in harmony. eNlight cloud hosting represents an opportunity to reduce maintenance costs and this is recognized in the prices that we charge for resources with our cloud hosting services; ESDS believes in offering affordable web hosting to all users and eNlight allows us to achieve this in the cloud hosting sector.
As a client using eNlight from ESDS you will have full control over your virtual machines from the comfort of our billing system. Features of your VMs that you will be able to control include:
New features are constantly being added to the eNlight cloud – we will soon be introducing the ability to setup a vLAN between multiple virtual machines so that we can introduce cloud-based load balancing.
IaaS-based cloud web hosting platforms provide customers with complete control over their web hosting experience, with emphasis put on the operating system used and the resources of virtual machines. eNlight from ESDS is a prime example of an IaaS implementation because our cloud hosting clients are able to develop their virtual machines with the resource that they wish to see, as opposed to choosing a pre-defined web hosting plan as outlined by other forms of web hosting. IaaS implementations can provide businesses of all sizes with a variation of benefits such as:
Additional control of particular networking components is also a possibility because to some degree it is important for businesses to have control over factors external to their cloud virtual machines. Popular options chosen by larger users of cloud web hosting can include:
ESDS utilizes the concept of IaaS with our eNlight cloud hosting services, one of the most advanced cloud hosting platforms available today. We also offer private cloud solutions for situations where a shared cloud doesn’t provide the desired level of control.
PaaS services related to applications or services that are hosted in a central location where the user doesn’t have control over the operating system layer or any of the hardware involved. The best example of PaaS is where Microsoft Exchange Server email hosting is offered within the context of a shared platform where multiple users share the same Exchange server environment; here the consumer will have no control over the hardware, OS or application layers, but can create additional email accounts that can access and use the Exchange environment. Benefits of PaaS services include:
The only downside to choosing the PaaS hosting model is that you as the web hosting company are responsible for the management of the platform as a whole, but if you have a 24×7 support team such as the one that ESDS has at its disposal then it is easy to appreciate the benefits that PaaS can bring to businesses. PaaS should be seen as an alternative to situations where otherwise a dedicated server would be considered for application where it isn’t really necessary.
You may not realize it, but a majority of the time you are probably using a SaaS-based service. SaaS based services serve the software directly through a web browser in a fashion meaning that the consumers has no control over any of the underlying layers, including the application layer. SaaS is often used to deliver applications that are designed through a specific service through a web browser; these applications could otherwise manifest themselves as desktop-based applications, but this introduces system compatibility issues, as individual versions will need to be developed for different operating systems.
Examples of SaaS applications include HR and Finance applications for businesses that require access from a multitude of locations and because of this a desktop application would be inconvenient; a centralized operation provides a central point from which applications can be managed and updates can be applied without the need for any intervention from consumers. Web hosting companies, including ESDS, use SaaS billing applications for the management of their finances because web hosting billing applications tie into a business’s infrastructure to control further aspects such as servers and web hosting accounts.
The cloud is designed to offer a centralized platform on which applications and services can be delivered to any internet-connected devices, compared to standard web hosting plans that are often designed for the hosting of websites and web applications only. eNlight from ESDS is a scalable platform that businesses of all sizes can take advantage of for their corporate hosting needs as you can host as many virtual machines as you require with us and the availability of resources guarantees that you will be able to match your VMs with the resource assignments that you deem as necessary for the stable running of your cloud servers. Scalability isn’t available with other forms of web hosting and with the eNlight cloud it is instant because you can purchase additional CPU power and other resources for your virtual machines and these will be instantly provisioned to your VMs upon completion of your order; if your servers are facing high loads then this puts you in a position where you can remedy the situation immediately by ordering the resources that your server requires in order to keep up with demand.
One of your main intentions for choosing cloud hosting is likely to be the room that you will have for expansion; this is necessary to ensure that you can grow your website to keep visitor numbers growing and to improve the percentage of returning visitors that you receive. The eNlight cloud can assist with this in the following manners:
Compared to web hosting, the eNlight cloud from ESDS can provide you with a greater level of uptime, which we rate at 99.95% each month. Full support is available 24×7 so that you can have assistance with the setup and configuration of your virtual machines where necessary.
eNlight from ESDS is hosted out of our data center located in Nashik, India. This state of the art facility is a Tier 3 location and makes use of the latest technologies to provide one of the most secure and modern hosting environments available in India. The eNlight SLA details that all hardware is covered by a 99.95% uptime guarantee and we aim to meet this using a number of methods, including a network that is based entirely around Cisco networking equipment because of its notable reliability and using high-specification HP and Dell servers to form our eNlight hosting cluster. The ESDS facility utilizes the following features to provide a secure and reliable environment for our customers:
ESDS offers a range of shared cloud, private cloud and dedicated hosting solutions from our data center in India. For businesses with more complex requirements then we are also able to offer co-location services that are also supported by on-site staff around the clock.
“Cloud computing” – the next leap to the digital world communism “matrix” or a heavy step towards total control over the information? What can we expect in the near future, and what is happening right now on the other side of the monitor?
How It All Began
To go back to the beginning of a generation ago, when many of us have walked under the table, the trees were big, and the computers occupied entire rooms in the Institute. At the time of tube computers, computer was a set of huge cabinets that were calculating, recording and storing the information.
Access to these so-called “mainframe” was carried out with the device as input (keyboard \ card reader) and output (monitor and \ or printer) user space, which in common parlance was called “terminal”. Such terminals in one mainframe could be a few, all depending on the system performance. The user, when he had to calculate some data, received permission to use the computer, and entering the terminal through its program, waiting for processing and output the result.
Since then, dozens of years have passed, along with the development of electronic computers (there was a) decrease in size and is now one of the computing power of the mainframe fits into the normal cell phone. It would seem so much more? What can be improved in this situation?
It turned out there was more to aspire for. Indeed, with increasing computer power grew and the volume of tasks that they had to perform. Previously, a large computer center expected to fly to the moon, and today millions of navigation devices count your way through urban traffic jams.
And if you combine the power of these devices in a large computing center, and expect to get the path of a specific vehicle, and the movement of all vehicles in the city, and if the system receives a signal failure of traffic lights – ensure that the problem is updated to the repair team. For such purposes, we again need to create computer centers that have huge capacities.
But these powers in full will be used only during peak hours, and for example at night time in the equipment which is considerably idle and without much work load. Here to help us, there is a new trend in the computer industry “cloud computing”. Cloud computing is a term defining the shape of a group of powerful server computers that are not constantly engaged in the processing of a particular problem, and provide the resources to different “virtual” services according to their needs.
For example, in the afternoon, 90% of resources will be given to the regulation of road traffic, and at night will receive priority to processing tasks such as the results of the exam, and etc.
Cloud computing can be applied in any field, as in the systems regulating the vital functions of metropolitan, and large enterprises for the processing of priority at a particular point of data.
What’s the difference between conventional computers and cloud computing services?
In the cost! The implementation of “mainframe” – “terminals” are substantial savings to the user’s computer as a terminal, to access the mainframe that does not need an expensive system that prevents the unit under the table, just connect to a monitor and keyboard, a miniature box, which will be on a local area network, transmit data input from the keyboard to the server and return back to the graphical information to the monitor.
Since in this embodiment, all data is stored on the server, it greatly simplifies the task of staff in the organization of data safety. Primarily and more – not only data is stored on the server, but also the software to work with them, so the user is no longer bound to a particular site, he only needs to remember the username and password to access the server of the enterprise.
As a result, he can happily go on a vacation, knowing that in the event of an emergency, from anywhere with an Internet connection you can get into your “workspace” and operate the necessary programs. A company gets more and saves money on licenses for the programs, because there is no need to install them on each user’s computer, just enough to purchase the necessary number of licenses based on the maximum possible simultaneous use of programs.
For home use
The undeniable advantages of this system has a home version of the application. Modern high-speed connection allows you to watch movies, “online” without downloading them to your computer. In the case of cloud all the movies that you bought, will be stored on the servers without taking up space on the shelves of your home, and can be accessed from anywhere. And also to play games, work with texts.
Many well-known companies have already taken up the idea of cloud computing and deploying them. For example Google.docs service allowing to collaborate on documents with people of different area, or eNlight Cloud from ESDS stores and host your files.
At the same time, some of the leading bookkeeping use such systems to store data in a safe place, often abroad, without losing the ability to work with them. The use of such offshore mainframe allows company executives to not to worry about their computers with all the accounting information.
