In 2012 the bandwidth used worldwide is worth growing, because users who access the Web are growing in number and data center service providers, as well as ISPs providing connections to homes and businesses are faced with an ever increasing demand for bandwidth output from their servers.

The bandwidth, which we will cover in this article as a monthly traffic, is surely one of the parameters of interest when one talks of a webhosting solution. Whether it’s a shared hosting solution or a dedicated server, your ISP gives value to bandwidth, which indicates the speed at which our website may provide content to the outside users, and a value of traffic per month , Instead it indicates how many gigabytes does our site use every month. These two values are in fact relevant, in fact if we multiply the bandwidth available to us for the month of use we get exactly the maximum monthly traffic that we use for our web site.

Many customers, when choosing a solution for a new web site, or already launched website, find it difficult to estimate how much bandwidth is needed for their site, and therefore rely on solutions that are often not suitable. In this article we see, briefly, how you can get an idea of bandwidth consumption and how to predict the increase in the short term.

The traffic monitoring carried out by our web site is crucial for several reasons. The most obvious is that many hosting solutions charge the cost as per additional GB over the threshold limit. If our plan includes 20 GB of monthly traffic, and the use is 25 GB in a month, then we will have to pay extra amount to the provider in excess of that 5 GB bandwidth.

The same applies to the VPS and dedicated solutions where the charging is often even   more stringent. Monitoring of the traffic allows us to understand the days with more visits and requests from users, and may be the wake-up call to see if the traffic generated is not entirely “normal“, but produced from attacks on our web site (DDOS Attack) or by search engine bots or other organizations that require our pages all the time.

The speed will change significantly if the bandwidth is completely used: In this case, the provider does not provide us with tools to understand how much bandwidth we are using in real time, except in the case of dedicated servers and VPS. Many shared hosting accounts have such a dedicated bandwidth of 512 kbit / s or 1 Mbit / s, while other vendors prefer not to expose this value.

As previously mentioned, the value of bandwidth is a parameter connected to the monthly traffic, however, it has a greater importance in some cases because it allows to understand exactly how many visitors we can accommodate simultaneously online, with a continuous request for content from our account or server. Take, for example to the streaming services, or to services providing multimedia content, in this case it is essential to have a value guaranteed bandwidth.

If our website is already online, the first thing to do is have an idea of the current consumption that we are producing. In this case we take a look at the statistics of the web server, and more importantly, we cannot use tools like Google Analytics, which do not provide information about the use of bandwidth.

Two tools that we can take into account are AWStats and Webalizer. These two statistics software are installed by almost all hosting providers which allow you to check the bandwidth usage on a monthly, daily and even hourly basis.

Many hosting providers, especially in the case of dedicated servers and VPS, from their control panels provide the ability to monitor the traffic used to be able to get an idea of monthly consumption. The control panels such as Plesk and cPanel provide the ability to monitor the bandwidth usage per web site, on a monthly basis. Once we have a clear idea of the consumption of our website we can certainly provide the best future growth even and especially to move towards a web hosting solution that can guarantee the traffic without any problem.

Now that we have seen that we can use statistics to get an idea of the consumption of our web site, the question is trivial, as we do in the event of a new website. First we must understand what we talk about in detail: a website that was launched with much content online without any promotion on dedicated channels, it is hard to see thousands of visitors on the website daily.

Unfortunately in this case we do not have technical data: Study the impact of an online site meets several qualitative questions. If we plan an advertising campaign on multiple channels, we can now estimate a high number of visits (proportional to the number of channels and the channels chosen for ad), and if our web site relies solely on organic traffic and search engine traffic, we cannot get 2000 daily visits.

We can try to understand the consumer as well for visits: It is easy to “measure” the content. First we make our web pages and do an average of their weight. Today, a page can easily get a weight of 400/500 Kb: we know that in this case if you open it 10 times, we used 4 MB of traffic, if they are opened 100 times, 40 MB is used and so on.

With an estimate of the traffic generated from our website, on a given day, we must consider a number of additional variables: the majority of websites have days during the week where the traffic is higher, these are usually working days, but this pattern may change depending on the website. Like, the night of the Web sites are those where less traffic ever recorded. Once our website has been online for a few weeks we will have a clearer idea of the days with higher consumption and hours in which there is a spike in visits.

If we talk about solutions such as VPS and dedicated servers, then it is evident that the monthly traffic and bandwidth are values that need to be taken into strong consideration: providers set limits in terms of guaranteed bandwidth, such as 10 Mbit / s, and in terms of band burst, ie the quantity of excess bandwidth that can be used for a limited period of time.

If our server has dedicated 10 Mbit / s guaranteed bandwidth and 15 Mbit / s burst of bandwidth, means that for a certain period of time in the day we get to use the value of 15 Mbit / s.

Currently there are dedicated servers and VPS packages which are activated with flat rate, where they also have several terabytes of traffic including: in this case it is useful to understand what is the guaranteed minimum speed for use thereof.

In the case of shared hosting solutions: Nowadays many hosting providers do nothing but place the value of “unlimited” bandwidth that can be delivered out, a practice that may mislead customers as unlimited resources do not exist. This choice is due to the fact that most shared hosting customers have an average consumption of the infrastructure of the hosting provider. This does not mean that our web site can really accommodate millions of visitors, usually the contract of service raises this issue clearly and frees the provider from liability for the suspension of the service if excessive traffic is carried.

I’ve been following cloud computing for some time and every day I see that it is accelerating the ripening process and trying to understand its concept and technologies. Today it is clear that, in its various forms, cloud computing has the potential to significantly change the way IT operates, and manages and allocates its budget, and pays for its use by users. Of course it is a change that does not happen abruptly, but gradually.

Public clouds, for example, while still generating fears of security and privacy, which are in my opinion, largely unfounded, no doubt put pressure on the structure of IT. Why keep a set of dedicated servers often idle, and a staff dedicated to operations that do not add value to upgrades of operating system releases if I can transfer this activity to a trusted provider?

Moreover, when analyzing the portfolio of applications in a company, we found that most of them are not strategic or critical to profile data that is not sensitive in terms of security. And we also observed that most of these applications could operate in an environment of less than 95% availability. However, these applications can be moved to public clouds without any major scares. In fact, a public cloud can offer a level of security and availability much higher than that offered in many of today’s data centers to small and medium enterprises.

The topic cloud also begins to permeate discussions of strategic companies. In a meeting with business executives and the CIO of a large company it became clear that they were already considering that a significant portion of its future computing power would be served by public clouds, with a consequent impact on the IT budget,  which will shift the costs of “Capital Expenditure” to “operational Expenditure”.

On the other hand, the concern of disintermediation by IT users in many areas also appeared at the meeting, as they begin to look for other solutions, cloud, SaaS, without even interacting with the CIO. This is a challenge that IT has to face because uncontrolled spread of a cloud for the organization can create problems of integration, lack of adherence to security policies and increase the risk of audit to identify issues of governance.

The CIO has to play a proactive role in the process of adoption of cloud. Indeed, the question is not whether or not to adopt cloud, but what is the pace of adoption. The first step is to identify which applications exist, which may at first go to public cloud and / or private and create a catalog of services and applications that will be available in the clouds.

For example, the CIO can begin reviewing applications available today under two points of view, a level of criticality and the other how they are strategic to the business. Most applications will be below of the critical level and can be transferred to public clouds.

The pressure for cost reduction is constant and note that it is increasing every year. At the same time the complexity of the business environment demands faster responses and increasingly complex IT solutions. Seems an equation without answers, but if we analyze the potential of cloud, we can immediately identify:

1) Move non-critical (and not strategic) applications and not strategic to public clouds,
2) Implement private clouds for certain controlled environments such as development and testing, increasing the cycle
3) Create service catalogs that allow the user to operate in self-service, with minimal interference from IT.

These actions help to better understand what is cloud and its potential while allowing the organization to adjust and refine their governance processes, already contemplating cloud computing. It also helps to more accurately implement charge back processes that are indispensable when it comes to cloud computing.

Services to create a catalog that includes internal and external applications (SaaS), similar to an Apple AppStore is an innovative and highly efficient way of providing services to users. The IT department can and should define the rules of the game: Which applications can enter the catalog? The IT department should establish an approval process that can evaluate cloud providers and SaaS applications available. Thus, IT does not become a bottleneck and at the same time clearly shows that it is actively driving the process of “cloudification” in company.

The important thing is that, IT understands that its role does not disappear with the cloud computing model. It remains responsible for providing the best services in the lowest possible cost.

Cloud changes the context: IT is no longer the only provider of the service and should leave this monopoly role and assume a new role. So sometimes the best solution is built, developed and operated by IT and other best alternative is to operate in a public cloud. IT should be at the center of these decisions and for that, the mindset must be changed.

Cloud… The name recalls the images of a shadowy fog that is always out of reach. The reality of cloud computing can only seem mysterious. Before entering into this nebulous border in IT, it is important to separate the hype from reality.

In assessing these assumptions related to the cloud, researchers focused specifically on public clouds and made a simple question: Fact or Fiction?

Fiction – But Maybe Not For Long

While migration to the cloud is not yet universal, there is no doubt that it is a wonderful trend that will only grow with increase of its adoption and importance. According to a 2011 survey of Advanced Micro Devices, approximately 37% of companies are already using cloud. And 24% of respondents to the survey in 2011, among data center managers, retailers and engineers, said they have plans to follow or implement a cloud computing in the next 18 months. According to a recent IDC report, worldwide revenue from IT services in public clouds exceeded $ 21.5 billion in 2010 and projected to reach $ 72.9 billion in 2015.

Regardless of which one is more accurate, it is clear that the cloud market is growing – and is much higher than suggested the news a year ago.

Why The Problems And Delays?

Although providers have improved data security and privacy considerably since the beginning, persistent concerns over access to proprietary data, location and transfer continue to limit distributed adoption. The flexibility of the system in general is another concern with public clouds. Additionally, blackouts in various cloud providers are probably reason enough to discourage some businesses that depend on the availability of fixed network for survival.

Switching To Cloud Means That You No Longer Have To Worry About Downtime..

Fiction  

If your company switches to an external cloud provider, the risk of a blackout is simply transferred to their data center provider. The only change is the control. In its own data center, you control the infrastructure and availability of your network and data. This control, of course, brings many problems of ownership and responsibility with it that may have been a factor in the shift to cloud first. The control means responsibility, and the burden of responsibility for ensuring network availability is something that some IT managers prefer not to be responsible.

If your organization chooses private cloud, you can gain a measure of fault protection for a single server, but the damage caused by a total blackout in the data center continues to be destructive. To maintain a robust infrastructure, power and cooling, it is critical to support a private cloud infrastructure. The management and monitoring of data center becomes even more critical.

Finally, it is important to remember that simply switching to cloud does not eliminate the concern about downtime or damage that may cause a blackout to your business. Customers remember the  network failure – not the fact that the failure was the fault of your cloud provider.

Cloud Computing Solutions Always Reduces Costs And Workload

Fiction

This is a common argument for the adoption of cloud, but depending on the applications you plan to support with the cloud, this may or may not be true. At least in the short term, it is likely that a transition to cloud is very laborious.

Businesses that switch to this type of work do so to meet a specific need and leverage resources previously unavailable (especially dedicated servers) that, through the cloud, are available on demand.

But cloud services adapted to the specific needs of your business require a transfer of culture that can be difficult to manage. Even when the setting is appropriate, classifying what can and can not be changed for cloud is a process that takes time. The increased operational efficiency can be light at the end of the tunnel, but it is a short tunnel.

In terms of costs, cloud customers save money only when performing on specific cloud platforms. On the other hand, the report says that maintaining a private data center continues to have the best cost benefit.

The real protection depends on having the right architecture for the right application. Organizations must understand the individual requirements of their applications.

An excellent starting point for an organization wishing to implement a cloud computing platform is to examine the current IT architecture. Only by aligning the applications architecture – computers, network, data center and storage resources, do you get to keep the company on track to achieve the reliability and performance necessary for a good cloud environment?

In the area of cloud computing, real protection depends on having the right architecture for the right application. Organizations must understand the individual requirements of their applications and, if already using a cloud platform, understand the corresponding cloud architecture. With this knowledge, you can make decisions about what cloud platform responds to the needs of reliability and performance of your applications.

Listed here are five points to consider when evaluating cloud computing architectures:

Availability : Not all applications are equal, as all platforms are not on the same cloud. Organizations have to prioritize their applications, identifying those that must always be available and that may have breaks in service, and service breaks are acceptable. They must understand the risks associated with the unavailability of data. For applications that must always be available, it is necessary to consider high-quality technology and business class have been rigorously tested at the expense of developing an internal solution. It is also important to seek solutions for multi-site planning and disaster recovery / business continuity. For most organizations, this means working with a service integrator or a consulting firm, which includes these services in its core business.

Security : Security remains the primary concern for organizations looking to the cloud. Among the main concerns are loss of control of sensitive data, the risks associated with multi-user environments, and responding to various standards and compatibility needed. You must know how a multi-user shared environment is segmented in order to avoid overlapping customer service and breaking the boundaries that must be established between them. As the solution is architected, and the infrastructure of the Cloud service provider (network and virtualization platforms and storage) is secure.

Management : Organizations must understand what are their obligations, rather than just knowing what to expect from a service provider. Most solution providers of cloud do not support public administration. Or potential customers of these solutions have the expertise to design the right solution at home, or should seek the services of an outside vendor. There must always be an understanding of the level of management that their applications need and the identification of a process of changing management.

Performance : As in traditional hosting models, it is important to understand the requirements of workflow that will lie in the infrastructure. Organizations must also understand what their problems are and how is the cloud architecture that they have, or want to purchase. They must make their own tests to understand how a cloud environment can affect the computational resources, network and storage.

Compliance : Organizations must understand where their data is and who interacts with them, and how. They must understand the areas of compliance that the service provider controls and compare with the standards and regulations that they aim to join.

As reported in an article published in the pages of the New York Times, research experts conducted an experiment in which it was planned to find out whether wireless devices can be used for communications between dedicated servers, data center in the future or not.

The researchers set out to find out whether the use of wireless systems will speed traffic between servers, data center , if the basic (cable) system is overloaded in the near future. Several server racks in one of the centers were equipped with small corporations directional antennas for wireless devices and switching, which were installed on top of the server racks.

Used for communications range of ultrashort radio waves: The frequency – 60 GHz, the wavelength – about 5 millimeters. According to the researcher, the detailed system of wireless communications has allowed to significantly accelerate the speed of communication between the racks – from 45% to 95% depending on the specific experimental conditions.

It is known that wireless communications are often not completely reliable. Communication may be interrupted, for example, by the inclusion of a microwave oven or by unfavorable conditions for admission to a particular point. So it is the fact that this idea will be accepted by most operators or the data centers. Nevertheless, the situation in case of data centers is radically different from the usual situation with unreliable mobile phones with unstable connections to Wi-Fi.

The fact is that, the entire situation within the data center is under strict control, all occurring processes are well predicted, and the equipment is serviced by staff for uninterrupted services.  In addition, this system uses directional antennas, ie relationship between the switching devices is carried out through the narrow beams of radio waves.

While in recent months, access to applications is offered in pay per use model,  being hosted on shared data centers (which is known as cloud computing), (arguments) continue flying over the issue of security as a recurring objection to the general expansion of the use of the cloud.

Without wishing to deny the existence of risks, try to propose the following hypothesis: will have to set optimal levels of security that do not impede or complicate access and use of software applications and services.

There is a maximum security level, which is credited with 100% confidence that there will be no risks: always keep your computer off.

Most studies conclude the existence of quasi-apocalyptic risks that are computer security companies or service providers that impact on their levels of safety and business case.

Those who seem to have the most spyware code distributed around the world are governments, who in turn create the laws for the security checkpoint.

The group of non-internet users is precisely the one that seems to have security issues.

The setting of restrictions on access to internet sites has meant that, in most large organizations, employees have not been able to access critical information necessary for their work when they are needed.

The use of antivirus, antispam, … and other security services consume much resources and slow down the PC so that large numbers of personnel management and maintenance of networks and teams in organizations chose to uninstall them and have a copy of their data and their applications, which are  immediately restored on regular basis.

While centers reported that high level of security has localized malware code, which is not on specific devices, internal network or don’t know what type of malware it is, so presumably it exists, but their relation to any risk of physical security is virtually nonexistent.

The greatest risk for loss of information lies in overheating of the machine where it is stored. I would not be mistaken if I say that the control measures and physical security of any data center operating internet is much higher than any company that maintains the machines on their premises.

The above statement is also valid for the control and limitation of physical access to machines.

Below, we have listed some of the important points that can be used to consider the idea that offers remote working for staff members which can be an excellent alternative.

1 – More Productive Officials

When they work from home, they do not have the distractions of the office, and do not spend time in   transit. Several academic studies and surveys show that corporate remote workers are often happier and more productive than those who stay at company headquarters. Some workers may need supervision, but you can do this through production targets rather than to monitor hours worked per day.

2 – Reaching The Professional Team Wherever They Are.. Regardless Of Location

Generally, the adoption of telecommuting involves building the minimum appropriate infrastructure: software and appropriate internet connection. The tools include remote control applications, collaboration software and video conferencing software. It may be easier to reach team members via the web than walk around the office.

3 – Space Saving And Cost Cutting

The remote worker not only uses his own desk and PC, but also electricity, snacks, water, broadband, telephony and more. This reduces costs for the office. Even if you reimburse some costs, such as connectivity to the Internet or using the phone, you’ll save space in the square footage of the company.

4 – Improved Management Of IT And Reduction Of Maintenance Costs

In general, remote workers provide their own connectivity and PCs If you need to install anti-virus, remote access, and other software, the total costs should be much smaller in comparison with the management in-house. You will need to set standards and perhaps implement their fulfillment, such as checking software to ensure that anyone who connects to the network is not infected with a virus or has outdated software.

5 – Enjoy Cloud-Based Services

Instead of hosting servers in your offices, you can take advantage of cloud computing applications that enable telepresence. The cloud applications can provide more reliable service than their your own servers. Cloud providers have multiple redundant data centers to ensure reliable connectivity.

Obviously, you will need to thoroughly investigate the available security and backup options for each service.

6 – Faster Business

If the tools are configured correctly, the remote working can make the company more agile, giving greater flexibility for professionals to meet project requirements. You can quickly find and recruit workers for specific projects.

7 – Cheaper Labor

If you are located in an expensive area, you can save substantial amounts of money. Professionals can live in regions with good and cheapest internet connectivity – and be satisfied with lower wages than in large cities. In addition, many employees accept a lower salary in exchange for remote working.

Finally, if you hire professionals through independent contractors, will save on the costs of payroll.

Remote work with the company can save substantial sums with few real disadvantages if you carefully manage security. The perception of difficulty in supervising remote workers, often seems to be the biggest barrier to implementing remote working, but it is possible to overcome this by looking for profit.

Although server virtualization technology is currently receiving much attention, the concept is not new. Actually the idea came in the mid-1960s, when the Giants and expensive computers of the day reached to a high processing speed but they were unable to seize the expensive computing time due to management processes that needed to be done manually by the operator. To get the best out of expensive computer processing, it was necessary to run multiple processes in parallel. Thus arose the concept of time sharing, which culminated with the idea of virtualization.

Time Sharing: This concept means sharing time, i.e., idle time between the processes are shared with other processes to streamline the system. Multiple jobs are executed simultaneously, and the CPU meets each job for a little while, one by one in sequence. The time dedicated to each job are small enough so that users can interact with each program to recognize that there are no other programs running.

In 1972, an American computer scientist, Robert P. Goldberg introduced the theoretical basis of the architecture for virtual computer systems in his dissertation at Harvard University. In the same year IBM introduced a mainframe that was able to simultaneously run different operating systems under the supervision of a control program – hypervisor.

The IBM System 370 was the first commercial computer entirely designed for virtualization, with which, the operating system CP / CMS allows you to run multiple instances simultaneously. This was followed by the IBM z / VM, which took advantage of hardware virtualization. The VM / CMS is highly regarded and widely distributed in the industry and academia. Several modern approaches to virtualization implementations are very unique for mainframe of computers from IBM.

Over the years, virtualization has begun to fall by the wayside due to creation of new client / server applications and the decline of the mainframe platform that lost power before the rise of the x86 platform. According to VMWare, the widespread adoption of Windows and Linux as the operating system on servers in the 1990s eventually established the x86 architecture as the industry standard.

Due to high costs for the purchase of a mainframe, companies began to acquire x86 servers according to demand, this is a process called low-end (several small machines doing the work of a large dedicated server). In this scenario, instead of having a high initial cost with the purchase of a mainframe, they opt for purchasing smaller servers according to need.

The impact of this new strategy was to ensure  a good deal of backlash against hardware scaling problems, and most of these servers were used for a single application. Thus, according to International Data Corporation, in each implementation of a typical x86 server, the roof of CPU usage was between 10 to 15% of the total capacity of this server.

The servers were oversized for the application that would perform, and as a result, ended up suffering the same problem of mainframes of the 1960s, that is, not all took advantage of their computing power,  and were underutilized.

Then in 1999, VMware Inc. introduced the concept of virtualization on the x86 platform as a more efficient way to operate the equipment of the platform, taking advantage of x86 servers to provide a computational structure that would enable the full utilization of computational resources of these servers.

From 2005, processor manufacturers like Intel and AMD have given more attention to the need to improve hardware support in their products. Intel with its Intel VT and AMD with AMD-V. These hardware contains features which allow to exploit hypervisors that are used with the improved technique of virtualization (full virtualization) that make it easier to implement and enhance the performance.

The term web hosting, more commonly abbreviated as “hosting” means the practice of hosting one or more websites on a web server, accessible over the network and then viewed by online users.

The web hosting is a service provided by millions of companies worldwide who are called “Web Hosting Provider” or simply “hosting provider”. The owners of web hosting allow a website to have a space with certain characteristics (disk space, monthly bandwidth, email accounts, databases and other services). Within this space all web pages, images and general content required for the operation of the website are saved: a domain, such as www.esds.co.in is connected to this space so that the site is publicly accessible.

The web hosting services are hosted on servers, and these in turn reside in particular physical structures called Data Center, designed to have low temperatures and ensure continuity of service, so that websites will always remain visible.

The web hosting providers usually provide different levels of web hosting services that include:

• Dedicated Server
• virtual servers
• colocation web hosting services
• cloud hosting and applications hosting

How Many Web Hosting Companies Are There?

Currently in India, as well as in the rest of the world, there are thousands of companies that provide web hosting services: the distinction between them is mainly due to the fact that each decides to host their servers in a different nation.

These are real companies that work with staff specializing in providing customer service and maintenance of servers online: this type of activity is not performed with the same quality from all operators, and this leads to a differentiation of solutions and prices in the web hosting market.

Please refer to the section on choosing a web hosting company for all information and advice when purchasing a web hosting service.

Key Features Of  A Web Hosting Service

We conclude this brief introduction to web hosting services, listing what are the elements that are usually included in a web hosting service. A web hosting service is built with a number of features and technical elements:

Domain name: (such as www.esds.co.in) to associate the web space (website)
Web Space: 50 MB up to 20/30 GB of space to publish the files
Monthly bandwidth: the amount of bandwidth that we can use for our account
Subdomains: it is shaped as webhosting.esds.co.in, restricted or limited in number
Control Panel: software that allows you to manage your account
E-mail boxes: vary in the number and size available (these services usually also include Antivirus and Antispam)
Databases: MySQL, SQL Server or other types used
Statistics: a tool to monitor the access and visits to the pages of our website
Supported languages: PHP to Ruby on Rails, specify what types of programming languages that we use to write the pages of our website
WebMail: A tool to view your email online, in your browser.

Conclusion

In this article we have seen what is meant by web hosting. Services are often very complex and within them, as we have seen, there are dozens of different characteristics. Use our search engine, on top of this page, for the information and terms that you are not clear about.

The sector recorded a real race for the virtualization of data centers and server hosting, in the wake of technological and economic advantages it can offer. The companies, however, should be conscious of the risk arising from plunging too quickly into cloud computing services, since virtual environments have many implications of compliance and safety.

Without doubt, virtualization creates an additional layer within the IT infrastructure, where often traditional security software, designed for physical environments, has a lack of visibility. This introduces vulnerabilities into the network, and visible gaps in the traffic between VMs. The new virtual machines that are installed automatically on the platform (especially in the case of an uncontrolled expansion of the VM) should be protected, regularly and systematically. The VMs are migrated from one physical platform to another – due to expansion of infrastructure or broken hardware – it also needs to be protected and monitored to avoid downtime during the live migration of VMs.

In addition to these internal threats, companies must protect their virtual environments also against external threats. Virtual environments can be even more dangerous than physical since the same techniques of attack and the same threats that exist in the physical layer exist in the virtual platform, where applications are not physically separated. This means that if a host server is under attack and the virtualization layer is compromised, this too can expose all the virtual machines to compromise on the infrastructure, all applications and data.

What are the best security practices for maintaining a secure virtual network?

The ideal solution must provide the same level of security present on the physical servers, virtual machines and applications:

First of all virtual machines too separate and protect the traffic between them, and hypervisor. The integration with it is important to ensure that the protection is running the hypervisor itself, not only on the virtual machine.

Secondly, the solution must proactively protect against external threats, with firewalls and intrusion prevention capabilities.

Third, to ensure unified management for both physical and virtual environments, making it easier for administrators to manage security.

It is important that the solution does all the above, without compromising the flexibility and scalability of the virtual system – security should help to exploit the benefits of virtualization, and not to mitigate them.

In addition, the solution must provide protection at all levels of security and not only at the network level. Of course, all levels of protection applied to the movement in the physical world, must also be implemented in the virtual environment.

Conclusion

Virtualization, as each new technology presents new risks for a company, incorrect implementation of security for a real environment may negatively impact on a company, exposing it to new risks and threats to security. For this reason, the implementation of the security architecture must be appropriate in a virtual environment, and knowledge of how to stay updated and protected against both internal and external threats, is a must for IT managers.
