How do I use a placement policy to spread VMs by memory

If you want to balance your deployed resources across multiple cloud zones, you can use the IaaS API to define the placement policy in a project and its cloud zones. When you deploy a cloud template that uses the project,
VMware Aria Automation
 allocates new VMs to zones and clusters with the most free memory, effectively spreading them for better memory usage.

Prerequisites for defining a placement policy

How to specify spread by memory in your project

This example shows how to find the project with cloud zones where you want to place your VMs. Then using the project ID, you update the project with
"placementPolicy": "SPREAD_MEMORY"
 to spread VM memory use across the cloud zones.

How to specify spread by memory in cloud zones

This example shows how to use the cloud zone IDs in the project ID
6c2f2d0d-ecee-42e3-90be-7bb66d6da2f9
 to check free memory in compute resources. Provided that free memory is available, you update the cloud zones with
"placementPolicy": "SPREAD_MEMORY"
.
