Compute Policies
VMware Cloud on AWS comes with DRS automatically enabled. The DRS parameters at the cluster level are controlled by VMware and cannot be adjusted by the cloudadmin role. However, customers have the ability to create compute policies that incorporate affinity or anti-affinity rules using vSphere categories and tags within the SDDC. These policies help govern workload placement and influence DRS behavior.
There are several types of Compute Policies available:
- VM-host affinity rules: These rules ensure that VMs are placed on the same host to optimize performance. For example, they can be used to isolate intra-VM communication on a single host or allocate important workloads to underutilized hosts to prevent resource contention.
- VM-host anti-affinity rules: These rules maximize workload availability by running applications on separate hosts, reducing the impact of host failures.
- Disable DRS vMotion: Compute policies can be used to prevent workloads from...
