An application instance can be deployed to one or more zones. A zone in this documentation
refers to a Vespa zone, the basic target location for the deployment of an application instance. A zone is
identified by an environment and a region identifier, for example
prod.aws-us-east-1c. This zone can be found in the below list of zones in Vespa Cloud.
A zone supports one or more availability zones.
The prod.aws-us-east-1c zone is in the AWS availability zone with AZ ID use1-az6.
Zones in Azure and GCP support the availability zone given by the region identifier, for example
prod.gcp-europe-west3-b is in the GCP availability zone europe-west3-b.
You can read more about zones supporting more than one availability zones in regional zones.
If an application requires zone-specific configuration (e.g., different capacity requirements per zone), use environment and region variants. Also see deployment.xml.
dev zones for development and performance testing:
| Environment | Default | Region | Availability Zones |
|---|---|---|---|
| dev | Yes | aws-us-east-1c | use1-az6 |
| dev | No | aws-euw1-az1 | euw1-az1 |
| dev | No | azure-eastus-az1 | |
| dev | No | gcp-us-central1-a | |
| dev | No | gcp-us-central1-f |
prod zones for production serving,
with a CD pipeline:
| Environment | Region | Availability Zones |
|---|---|---|
| prod | aws-us-east-1 | use1-az1 to use1-az6, except use1-az3 |
| prod | aws-us-east-1c | use1-az6 |
| prod | aws-use1-az4 | use1-az4 |
| prod | aws-use2-az1 | use2-az1 |

| prod | gcp-us-east4-c | |
| prod | gcp-us-west1-c |
The prod zones use ephemeral instances for system tests and staging tests,
running in test and
staging environments.
These are internal zones, and never directly deployed to, included here for reference:
| Environment | Region | Availability Zones |
|---|---|---|
| test | aws-us-east-1c | use1-az6 |
| test | gcp-us-central1-f | |
| staging | aws-us-east-1c | use1-az6 |
| staging | gcp-us-central1-f |
