Application manifests

Can the team deploy the representative application and its dependencies?

Azure Red Hat OpenShift: With Azure Red Hat OpenShift, deploy the representative application and its dependencies.

Azure Kubernetes Service: With Azure Kubernetes Service, deploy the representative application and its dependencies.

The workload becomes ready and all mandatory integrations work.

Persistent data

Can the team restart a stateful test workload using its volume configuration?

Azure Red Hat OpenShift: With Azure Red Hat OpenShift, restart a stateful test workload using its volume configuration.

Azure Kubernetes Service: With Azure Kubernetes Service, restart a stateful test workload using its volume configuration.

The workload recovers the expected data.

Workload identity

Can the team access one cloud service through the intended workload identity?

Azure Red Hat OpenShift: With Azure Red Hat OpenShift, access one cloud service through the intended workload identity.

Azure Kubernetes Service: With Azure Kubernetes Service, access one cloud service through the intended workload identity.

Only the required permissions are granted.

Upgrade exercise

Can the team rehearse a supported non-production upgrade?

Azure Red Hat OpenShift: With Azure Red Hat OpenShift, rehearse a supported non-production upgrade.

Azure Kubernetes Service: With Azure Kubernetes Service, rehearse a supported non-production upgrade.

Downtime, rollback and remaining operating tasks are documented.

Scope and architecture

Azure Red Hat OpenShift provides a managed OpenShift platform, while AKS provides managed Kubernetes. Evaluate OpenShift-specific application and administration requirements before deciding that the simpler Kubernetes service covers the same scope.

A common Kubernetes API does not make cloud storage, ingress, workload identity and network policy configuration automatically portable. OpenShift also adds its own platform conventions and administration model.

Cost and migration planning

For Azure Red Hat OpenShift, include selected OpenShift and Azure resource configuration. For Azure Kubernetes Service, include cluster configuration, compute, storage and networking. Use the same workload and resilience assumptions, then confirm current vendor terms for the selected configuration.

Deploy the actual manifests, images, secrets, ingress and persistent volumes in a non-production environment. Document remaining node, upgrade, security-policy and capacity responsibilities for the exact selected operating mode.
