3. vSphere
A collection of products including not only virtualization, but also control and inter-face layers, VMware virtualization platform vSphere. It provides various key elements (vCompute, vStorage, vNetwork), application services, vCenter Server, vSphere Client and so on.
Features of VMware vSphere:
- vCenter Server: A centralized management tool used to configure, provision and manage virtual IT environments.
- vSphere Client: vSphere 6.7 has the final version of Flash-based vSphere Web Client. Newer workflows in the updated vSphere Client release includes vSphere Update Manager, Content library, vSAN, Storage policies, Host profiles, VMware vSphere Distributed Switch™ topology diagram and Licensing.

- Virtual SMP: Enables a single VM to use multiple physical processors at a time.
- vMotion: Enables live migration with transaction integrity.
- Storage vMotion: Enables VM file migration from one place to other without service interruption.
- High Availability: If one server fails, VM is shifted to other server with spare capacity to enable business continuity.
- Distributed Resource Scheduler (DRS): Assigns and balances compute automatically across hardware resources available for VMs.
- Fault Tolerance: Generates copy of primary VM to ensure its continuous availability.
- Distributed Switch (VDS): Spans multiple ESXi hosts and enables considerable reduction of network maintenance activities.
