An application can be deployed to a zone, which is a combination of an environment and a region. This explains the rules governing the various environments. A list of all zones is also available.

prod must have at least one more node than required to handle peak load.
A cluster is a container or content cluster,
and a regular application has a container and a content cluster.
A minimal, typical
prod deployment therefore has 4 nodes.
Dev and Perf
perf are deployed to directly as part of development or testing.
In order to easily deploy application packages from prod applications, resources are downscaled - see Cluster sizes above. To override this downsizing, specify environment and region variants, like:
<nodes deploy:environment="perf" count="5"/>Setting environment explicitly enables exact node count.
perf, the latest active Vespa version is used when deploying.
An instance is not upgraded, unless deployed to.
This means that some times, a deploy takes longer than normal,
as it invokes a Vespa upgrade before deploying the application package.
