VMware vSphere is the leading enterprise virtualization platform, consisting of the ESXi hypervisor and vCenter Server management platform.
Key Features
- ESXi bare-metal hypervisor for running virtual machines
- vCenter Server for centralized VM and host management
- vMotion for live migration of VMs between hosts
- High Availability (HA) and Distributed Resource Scheduler (DRS)
- vSAN for software-defined storage
- NSX-T for software-defined networking
Enterprise Use
vSphere is the dominant server virtualization platform in enterprise data centers. Organizations use it to consolidate physical servers, improve resource utilization, and enable disaster recovery through VM replication. Veeam Backup & Replication is the most common backup solution for vSphere environments.
Tips
- Size clusters with N+1 capacity to ensure HA can restart VMs after a host failure.
- Monitor datastore capacity and performance — storage bottlenecks are the most common VM performance issue.
- Use vCenter tags and custom attributes to organize VMs for filtering and reporting.
