VMware Distributed Resource Scheduler (DRS)
VMware Distributed Resource Scheduler (DRS) is a feature introduced by VMware that automates the allocation and balancing of computing resources across a cluster of hosts within a virtualized environment. Introduced in the mid-2000s, DRS continuously monitors CPU, memory, network, and storage usage across hosts and VMs, and dynamically migrates VMs between hosts to optimize resource utilization and performance. DRS uses load balancing algorithms to ensure that resource demand is evenly distributed among hosts, thus preventing resource contention and maximizing the efficiency of the infrastructure. By intelligently balancing workloads, DRS improves system performance, enhances scalability, and simplifies management in VMware vSphere environments.
