To provide services to the infrastructure, vSphere relies on two core components—the hypervisor, which is the virtualization layer for the complete environment, and vCenter Server, which centralizes the management of the ESXi hosts and allows administrators to automate and secure the virtual infrastructure. To complete the vSphere deployment, it is essential to know the interaction between ESXi and vCenter. Let's examine these two components to figure out their role:
- The ESXi hypervisor is the virtual platform on which virtual machines and virtual appliances run. Its main function is to provide the resources to workloads in terms of CPU and RAM. To manage the ESXi resources, ensuring performance and reliability, an additional component is necessary—vCenter Server.
- vCenter Server is a service that centrally manages ESXi hosts...
