The concept of server virtualization is gaining popularity at a fast pace. The technique is used to minimize infrastructure cost and making the processes more refined and consolidated. The flow of data is also easily manageable through server vitalization. As you may know that server virtualization means hosting multiple virtual machines on a single server, each of these virtual machines are accessible by a user who uses them as his personal desktop. Although many companies now tend to shift to server virtualization, the decision should be taken after considering at least the following facts:
Selecting A Right Virtual Server
Before selecting a virtual server, remember that capacity of all virtual servers is not same. Some are good to host few virtual machines but in case you intend to host several servers through one virtual server, your requirements will change entirely. Microsoft Virtual PC is a good option for small setup but for more complex networks you may consider ESX Servers of VMWare.
Software Licensing Terms And Conditions
In case you plan to run virtual application, make sure you have read the terms and condition of the software provider carefully. Although in such a scenario, the application or software is installed only on server and used by multiple users, many software companies require a separate license for each user. They consider each user a separate user rather than a user sharing virtually installed software. There are few companies that allow you to install single software on server and give access to multiple users.
Ensure That The Applications Run Well In Virtual Environment
All applications and software are not usable for virtual environment. Before making a purchase, make sure that the software is supported by your virtual environment. Read through their features and specifications and make your decision accordingly.
Make A Shift From Windows Virtual Server
As already mentioned virtual servers from windows may not be appropriate for large and complex setups. There are number of virtual servers available and making a shift from windows can be a wise decision when it comes to virtual server. Try Virtuozzo which is supported by all operating systems. Many experts also recommend Xen and Open VZ.
Understanding Your Requirements
Going virtual requires good planning before actual deployment of the system. Your existing hardware capacities have to be taken into consideration and future requirements should also be taken into account. In case you think that the company will be expanding its operations in coming year or two, proper planning should be done for that expansion as well. Try completing your paper work before selecting your hardware and software for virtual environment.
Security concerns are greatly addressed by virtual environment. Server virtualization provides you an extra control over your data. The data usage, access and amendments can be easily monitored. You can also set permission rights and maintain your data integrity. It is difficult for hackers to access virtual servers. Data recovery is also easier in case of you having virtual server in place
Embedding The Change Is Business Process.
One of the main aspects of changing work environment is training the existing staff. Managing the virtual server is not very easy and professionals are required. In case your existing staff is not capable of to handle the system, proper training would have to be arranged or new staff would be required.
