Replicas

The Replicas page in the Console shows the runtime state of application replicas running for the selected instance.

Applications running in the instance are displayed in separate tables, such as Storefront and Additional applications.

What this page helps you verify

The Replicas page allows you to inspect the runtime state of application instances.

Use this page to verify:

• whether replicas are healthy and ready to serve traffic
• whether containers are restarting
• which deployment version is running in each replica
• whether a deployment rollout is replacing replicas
• whether runtime configuration was applied to running containers

What replicas represent

Applications running in the instance are deployed as containerized workloads. Each replica represents a running container instance of an application.

The number of replicas may change automatically due to:

• autoscaling
• deployments
• platform runtime operations

Deployments use a Blue/Green strategy.

When a new version is deployed:

• a new set of replicas is created for the new version
• health checks verify that the new replicas are ready
• traffic is switched to the new replicas
• replicas from the previous version are terminated

Because both versions may exist temporarily during this process, the total number of replicas may increase until the deployment completes.

Autoscaling behavior is managed by the platform and cannot be modified from the Console.

Application groups

Replicas are displayed in groups based on the application they belong to.

Typical groups include:

• Storefront – replicas serving the storefront application
• Additional applications – replicas for supporting services running in the instance, such as Middleware

Each group shows the runtime state of replicas belonging to that application.

Replica diagnostics

Selecting a replica opens detailed runtime diagnostics for that instance.

Containers

Provides information about the containers running within the replica and their runtime state. This helps confirm whether the expected container image is running and whether containers are restarting.

Environment variables

Displays environment variables injected into the container. This allows you to confirm that configuration changes were applied to the running application.

Events

Shows lifecycle events related to the replica, such as container start, restart, or scheduling events. These events help explain why replicas were created, restarted, or replaced.

Logs

Displays logs produced by the selected replica. Logs provide insight into the behavior of the running application instance.
