The factors to be considered in the planning of Application Virtualization

In the Application virtualization planning, the most important is a server can withstand the most users, users can get the best experience, also does not affect its scalability, reasonable use of resources.

Now the server's configuration is getting better, the CPU's kernel number and memory is bigger and larger, how to use and plan rationally, become a very important problem in the prophase of the project.

For example, how to use Windows Server 2003 as an Application virtualization server, can only assume a certain number of users, if the number of users need more servers, so management becomes a problem.

With Windows Server 2008, you get better performance, but some applications are not compatible, which is a problem that project planning must take into account.

In order to create an optimal planning scenario, you must balance the number of virtual machines with the operating system and performance of the virtual machine.

First, the server must be built on the user's needs and application characteristics,

Resources require a number of special applications for CPU and memory requirements are larger, the application determines the number of CPUs and memory size required.

Applications typically publish many applications on a single server, and how to plan properly is a problem.

Second, scalability

In planning, you must consider the later extensibility, such as the migration of virtual machines, the increase in the number of servers.

In order to migrate successfully, sufficient resources must be considered at the time of planning.

Like Xenmotion. , vmotion,live migratin need adequate resources.

III. licences

Microsoft's license should be considered in the planning,

The Standard Edition and the Enterprise Edition price difference is many, to many enterprises, the price also becomes an invisible factor.

The number of licenses also affects the number of virtual machines.

Note: In addition to, for example, xenmotion,live migration, or vmotion can also affect the number of licensing.

The license for the standard and Enterprise Editions is bundled with the virtual machine. If the virtual machine is on an enterprise server and needs to migrate to another server, the new physical server must have sufficient license.
