This page describes self-service maintenance, which lets you accept a maintenance update on your cluster outside of the typical flow of scheduled maintenance. To see which vulnerabilities are addressed by each self-service maintenance update, see Memorystore for Redis Cluster maintenance changelogs.
Overview
Memorystore for Redis Cluster releases software improvements regularly, such as patches for known vulnerabilities, through new maintenance versions. Although Memorystore for Redis Cluster schedules maintenance updates once every few months to ensure that you have the latest maintenance version, you might want to use self-service maintenance if any of the following conditions apply:
- You need an update sooner than your next scheduled maintenance event.
- You want to stay up-to-date with CVE patches necessary for FedRAMP Compliance.
You're not required to update to the latest version manually. You can let Memorystore for Redis Cluster update your maintenance version automatically during your next scheduled maintenance event.
Impact of self-service maintenance
Self-service maintenance updates have the same impact on your applications as standard maintenance updates. For more information, see About maintenance.
