A cloud zone defines a set of compute resources for a cloud account type, such as AWS or vSphere, in a specific account region that are used when you deploy a blueprint. Cloud zones are specific to a project.
Additional placement controls include placement policy options, capability tags, and compute tags.
Placement policy drives host selection within the specified region
default - place compute resources on hosts randomly
binpack - place compute resources on the most loaded host
spread - place compute resources evenly on all available hosts
Blueprints contain constraint tags to help determine deployment placement. During deployment, blueprint constraint tags are mapped to matching capability tags in cloud zones to determine which cloud zones are available for compute resource placement.
Compute tags help to further control placement during blueprint deployment after the cloud account match has been made.
After you create a cloud zone, you can validate its configuration.
