What does vCenter Server do continuously in the background?

vCenter Server plays a crucial role in managing a virtualized environment by continuously directing actions on virtual machines and hosts. It acts as the central management platform for VMware's virtualization stack, ensuring that resources are efficiently allocated and tasks are executed as intended.

This includes managing resource allocation, start and stop operations of virtual machines, migrating workloads across hosts (e.g., through features like vMotion), and monitoring the state of the infrastructure. By handling these actions in the background, vCenter Server helps maintain optimal performance and availability of virtualized environments, enabling administrators to focus on strategic management tasks rather than manual oversight.

While storing configurations of virtual machines, providing a graphical user interface for management, and monitoring network traffic are important aspects of a virtual environment, the continuous direction of actions is what fundamentally supports the operation and efficiency of the entire system.
