API

The IONOS CLOUD Database as a Service (DBaaS) In-Memory DB API lets you provision and manage fully managed In-Memory DB clusters for caching, real-time analytics, and message brokering workloads.

In-Memory DB API versions

DBaaS In-Memory DB offers two versions of the In-Memory DB API. Version 2 (2.0.0) is the recommended version for production workloads, while Version 1 (1.0.0) is the legacy implementation.

In-Memory DB v1 and In-Memory DB v2 refer to IONOS CLOUD's DBaaS API versions, not In-Memory DB software versions.

Note: The In-Memory DB v2 API is now in General Availability (GA). Any IONOS CLOUD contract can provision In-Memory DB v2 clusters without prior activation. For more information, see In-Memory DB v2 API.

Important:

• In-Memory DB v2, powered by Valkey, is now available, bringing Valkey (Redis®-compatible) engines in versions 8, 8.1, and 9. It also adds extended snapshot retention and native IONOS CLOUD Observability integration.
• Use In-Memory DB v2 to create clusters using the DCD or the API.
• In-Memory DB v1 has officially reached End of Life (EOL) and all legacy v1 clusters have been decommissioned effective August 31, 2026.
• An automatic migration from v1 to v2 is impossible. You must manually migrate existing v1 clusters to the new v2 infrastructure through the v2 API. For step-by-step instructions, see Manual migration.

What can you do with the In-Memory DB APIs?

The In-Memory DB API lets you provision and manage In-Memory DB clusters programmatically using standard HTTPS requests.

You can also use the In-Memory DB API to:

• Provision and configure clusters with your chosen size, version, and persistence settings.
• Monitor the operational status of any cluster.
• Retrieve and list clusters in your account.
• Modify cluster configuration, such as scaling resources or updating settings.
• Delete clusters you no longer need.
• Manage and retrieve snapshots for a cluster.
• Restore a cluster from a snapshot and track restore progress.
• Connect In-Memory DB instances to your managed Kubernetes clusters.
