RedHat Xen Virtualization

Realize your Virtualization with the assistance of CompecTA Consultation!

Nowadays, one of the greatest problem of the companies’ IT infrastructure is the expanding of server pools by chance. Having many applications and having a server for each application causes inefficiency in the usage of system room, in cooling and power consumption, in management point of view. The result is the inflexible IT infrastructure which does not support the workload and unexpected increase in the number of applications or which does not support the need in changing the IT strategies. Therefore IT managers enhance the rate of system usage and their flexibility besides the simplification of existing infrastructures.

What is Virtualization?

Virtualization, is the hardware and software solution that provides cost saving in new product and service development expenses which keeps you aways from the unneccessary software and hardware so that the available physical hardware could be used more efficiently with the support of virtual machines. By this way, tens of servers can be installed into a physical server.

“The average size of an institution can reach to the feedback rate of 472% within a year via the basic virtualization application. This is a significant feedback rate for which relatively cost efficient and easily applicable solution."

IDC July 2008

Enchance the Efficiency

Instead of using a separate physical server, enhance the usage capacity of your physical server by installing more than one virtual server into one server. And decrease your costs to 50 percent.

Decrease Power Consumption and Cooling Expenses.

You can decrease your needs regarding power consumption and cooling by running more application on less number of servers which is proportional to the number of servers.

Enhance your Flexibility

You can automatically move the virtual server which is located on server to another physical server without an interruption and within seconds. Thus, when the usage capacity of your application increases then you can automatically move the server which processes the application to another available physical server.

Do not stop your System for Maintenance and Operation

During performing of maintenance and hardware upgrading where you have the application running on, you can handle the operation without any interruption by transferring the virtual server to another physical server.

You can create Test Servers

You can test the new applications or test the virtual servers that you will create the new version of your application and you can use it if the application is confident. Thus you will not need to another physical server for test purposes.

Facilitate your Back-up

Virtual servers are the files which are created in the physical server' s hard disk. You will only copy this file as it serves as back-up to entire application adjustments and you can run this back-up file on desired physical server.

Run your Old Applications

You can run the old applications by installing old version operation system on the virtual server which is not supported by available operating system. Thus, you will not have to allocate an additional physical server for this application.

Do not afraid of the Hardware Failure

The virtual server which contains the application can automatically move to physical server without an interruption and without an interference in case of any failure in the server that you keep your very important application.

Virtualization is not the purpose, rather it is a Tool

It is the first priority of the companies to be strong in competition and to be one step ahead from the competitors. Nowadays, work processes are realized through the IT infrustructures. Having an effecient IT infrastructure ensures more ability in work performance with less cost. In that respect, if the aim is the productivity then the virtualization is the most suitable tool for the purpose.

The results of Virtualization Application

The virtualization that applied to medium sized companies, provides improvements for the system management, number of users that shall be serviced, uninterrupted service and flexibility point of view.

Virtualization Running Principle

More than one virtual server can run on physical server with virtualization engine. Virtualization engine is the software layer that runs on operating system of physical server. Virtualization engine handles all operating systems and take a place for interfacing between the software and hardware. This engine has continuous communication with hardware and can reach physically to anything related to hardware. Virtualization engine checkes the thing that needed to be performed on operating system side or on software side and acts as acted by hardware. Operating systems or softwares are not interested in how their requests are realized and they assumed that they are in connection peer to peer with hardware. Thus each server assumes that he runs on normal physical server. In this way, virtual servers can be created that is free from the hardware and which is transferable among the physical servers.

Why CompecTA?

CompecTA, was founded to cover the needs for professional engineering services that requires know-how in IT sector. The basic item of the staff profile is that the project engineers are educator origin besides, they are capable to reflect their experience in training as well. The point that we care while performing the engineering and the consulting is to ensure customer-oriented solutions. Analysing the relation between the job requirements and the technical requirement lies behind to make a decision to the best virtualization technology.

All virtualization solutions leaded by CompecTA are tested in his laboratories and prepared to perfect applicability by performing many stres tests. CompecTA also gives virtulation trainings regardless the curriculum is independent or dependent, besides providing the consultation for virtualization technologies.
