ADVREL04-BP02 Deploy new code or resources in staggered phases, separated by sufficient time, to verify that the changes are successful

Implement gradual, phased deployments to minimize risks and service impacts when updating systems.

Implementation guidance

When deploying new code or resources, it is possible for unintended results to occur. Various deployment strategies can be used to reduce frequency and service impact.

By making changes through a blue/green deployment methodology, you can significantly reduce the impact of any potential issues and avoid downtime.

When a blue/green deployment isn't possible, a rolling deployment methodology should be used to reduce the number of resources being modified simultaneously. With a rolling deployment, changes are made in small batches, with a pre-determined amount of buffer time between batches. If an issue occurs with the deployment, the unchanged resources can continue handling traffic, avoiding downtime.
