First

Good evening to all. I say about Little intro about VMware tools usage, but before seeing vmware we will understand why vmware came to industry.
Think about we have one big IT industry and  have thousands employees  so we need to maintain them records and also per day large nos of mail transactions will happen.  So need proper configuration servers needed for control and maintain the all systems like client request and server response and other similar processes . so system admin decide to  maintains those systems using three kind of servers. First one database server, second  mail server and last one file server.  Each server have good configuration like 2 TB hard drive, 4 GB ram  and supports processors.

If admin  build single server with above configuration, just fix approximately Rs 20000. Same time admin build three servers the cost crossed Rs. 60000. Here if we get proper working environment , must power on all servers. So every actions should proper. 
Now think about, any  possible to build all servers enter to single system. If above statement it's right, lots of profit will receive.
