What is vmware

The memory usage can be configured manually or dynamically. You have the option of limiting the memory usage on certain servers to prevent consumption of too much memory.

VMWare also allows you to allocate hard disk space from the available hard disk storage pool. The drives you set up will appears as if it is a physical hard disk that is installed on the server. Every VM virtual machine already includes an operating system and application. Each virtual machine on the server will operate independently on its own without any connection to other virtual machines.

The individual servers are just the same as the physical dedicated servers. Traditionally, a minimum vSphere cluster recommendation requires a shared storage infrastructure and three physical hosts. With the introduction of vSAN, a dedicated shared storage array is no longer needed. VMware has also partnered with public cloud providers to provide vSphere compatible infrastructure.

The second option is the vCloud Air Network of service providers. Service providers leverage VMware's cloud platform vCloud Director to provide multi-tenant cloud infrastructures. The IBM flavor of public cloud is the only publicly available option. Pricing for vSphere varies wildly based on desired features, the number of licenses, and other specifications.

It's complicated enough to merit a white paper on pricing and package differences that any potential vSphere customer should take the time to review. That doesn't include a year support subscription, the pricing for which also varies greatly based on the version of vSphere purchased.
