Which deployment option supports redeployment with zero downtime?

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

Answer: (D)

Redeploying with zero downtime means updating an application while users still receive responses, by bringing up a new version and switching traffic to it without breaking ongoing requests. CloudHub can do this by spinning up a fresh worker for the new version and then routing all traffic to it, so there’s no moment of unavailability. Runtime Fabric works at the container level and can deploy the new version to new pods or instances, then gradually shift traffic to the updated deployment, ensuring continuous availability. Private Cloud Edition and Pivotal Cloud Foundry don’t guarantee this seamless swap by default and often require more manual steps or downtime during redeployment. That’s why the option that supports zero-downtime redeployment is CloudHub or Runtime Fabric.
