Virtualization with VMware vSphere and ESXi

Platform virtualization refers to the creation and management of virtual machines that act like real computers with an operating system. All programs executed on such virtual machines are separated from the underlying hardware resources.

In hardware virtualization, the actual (physical) machine is the host where the virtualization takes place, and the virtual machines are the guest machines. The software that creates the virtual machines on the host hardware is called a hypervisor. At Livewire IT, we specialize in the implementation of the enterprise-level hypervisor by VMware called ESXi. ESXi is a bare metal embedded hypervisor that runs directly on the host server hardware without an additional underlying operating system.

The major benefits of virtualization can be summarized as follows:

  • Advanced resource utilization: fewer physical servers needed that contributes to energy savings, run multiple operating systems and applications on a single computer
  • Maximized uptime: technologies such as live migration, storage migration, and distributed resource scheduling improve business continuity
  • Improved disaster recovery
  • Isolated applications
  • Advanced support for Cloud Computing
  • Speed up and simplify IT management, maintenance, and application deployment

Virtualization is one of the most effective ways to reduce IT expenses while boosting efficiency and reliability for businesses of any size.
