What does a VMware administrator do?
A VMware administrator runs a company's virtualisation platform. They provision virtual machines, manage vCenter and ESXi hosts and clusters, balance resources, patch the platform and support disaster recovery. Their job is to keep the virtual environment stable and available, plan capacity ahead of demand and recover services quickly after a failure.
What certification does a VMware administrator need?
The VMware Certified Professional, or VCP, is the common certification for this role in India, and it proves you can run vSphere in production. Employers also value hands on experience with vCenter, HA, DRS, backup and recovery. Windows and Linux server knowledge helps, since virtual machines run those operating systems.
Is VMware still in demand with the move to cloud?
Yes. Many Indian enterprises still run core workloads on VMware in their own data centres, and hybrid setups that mix VMware with public cloud are common. Administrators who add cloud and automation skills stay in strong demand, because someone has to run the virtual platform and bridge it to the cloud.
