Redeployment with zero downtime is supported by which options?

• A. CloudHub
• B. Private Cloud Edition
• C. Runtime Fabric
• D. CloudHub or Runtime Fabric

Answer: (D)

Zero-downtime redeployment relies on updating the app without dropping user requests, typically using blue-green or rolling update approaches. CloudHub and Runtime Fabric provide built-in support for this pattern.

In CloudHub, redeploying spins up the new version behind the scenes and_ROUTEs traffic to the old version while the new one starts and passes health checks. Once the new version is healthy, traffic is gradually shifted to it and the old version is terminated, all without interrupting ongoing requests.

Runtime Fabric runs on Kubernetes, so it benefits from rolling updates. New pods running the updated version come up first and pass readiness checks, while existing pods continue serving traffic until the new pods are ready. Then traffic is redirected to the new pods with no downtime.

Private Cloud Edition doesn’t guarantee zero-downtime redeployment on its own; it may require manual orchestration or downtime, depending on configuration and tooling.

So, redeployment with zero downtime is supported by CloudHub or Runtime Fabric.
