When it comes to the decision of adopting Virtualization for an IT environment, many questions crop up in mind. Few queries that will certainly make you think twice about virtualization are:
- HOW MUCH SUITABLE WILL IT BE FOR THE EXISTING INFRASTRUCTURE
- NUMBER OF PHYSICAL HOSTS REQUIRED
- AVAILABILITY OF THE BEST AND COST-EFFECTIVE STORAGE OPTION
- RISK INVOLVED WITH CRITICAL APPLICATION
- EXPENSE OF THE INITIAL OUTLAY
Here comes the importance of Capacity Plan. Most of the doubts can be cleared through this Capacity Plan. With the help of Capacity Planning, we can measure the system performances including processor utilization, total storage, disk I/Os and much more. Though many critics may raise doubts about the effectiveness of Capacity Plan, but still this is the best answer to all the queries. Now in order to get 100% genuine information regarding the cost and scalability of a virtual IT environment, one needs to go through various channel of information and do cross-check.
At the beginning, Virtualization was costly for both the end-user as well as the engineer/analyst. The cost related to the capacity plan process was significantly high in the early days of virtualization. But nowadays, the market has changed a lot. There are many organizations, including ValueCare Inc, who are providing the service at an affordable cost.
As virtualizations are of different types, the cost of setting up an IT environment based on Virtualization platform varies. Virtualization platform is primarily three types:
- Full Virtualization: It helps to simulate the actual hardware that will allow software consisting of guest operating system, to run without any modification. .
- Partial Virtualization: In this case, the target environment is simulated partially. Some guest programs, therefore, may need modifications to run in this virtual environment.
- Para Virtualization: A hardware environment is not simulated; however, the guest programs are executed in their own isolated domains, as if they are running on a separate system. Guest programs need to be specifically modified to run in this environment.
