Overview

In-Memory DB is a key-value structure-based in-memory data storage. Data is stored in Random-Access Memory (RAM) instead of a disk and is swiftly available. Rapid access to data is provided by RAM instead of a disk.

IONOS CLOUD DBaaS for In-Memory DB is a fully managed service, compatible with legacy Redis® OSS that gives you access to the capabilities of its data structures. It can be used as a dedicated in-memory data store and a real-time database service. This combination enables In-Memory DB to deliver greater performance.

It is simpler to configure your In-Memory DB instance with IONOS CLOUD DBaaS. You get access to a secure, dedicated In-Memory DB server managed by IONOS CLOUD. DBaaS gives you access to the capabilities of the In-Memory DB data structures, which means that you can use the same code, applications, and tools you already use in your existing databases. You can use the In-Memory DB features, such as patching the In-Memory DB data structures, creating redundant backups, and enhancing security with IONOS CLOUD DBaaS.

When used as an in-memory data store, In-Memory DB accelerates data access from primary instances and associated data stores with minimal latency. This is quicker as compared to interacting with a traditional database. In-Memory DB acts as an in-memory data layer, speeding up the API response time while improving data retrieval.

In-Memory DB supports data persistence by writing data into long-lasting storage. For more information, see Data Persistence.

It is mandatory to specify a periodic maintenance time window for regular maintenance. During the maintenance time window, you may encounter short, occasional downtime. This is typically caused by restarting In-Memory DB or switching to another replica.

Provisioning a new In-Memory DB instance through a fully managed IONOS CLOUD DBaaS is faster than self-managed manual procurement, configuration, and installation of In-Memory DB on local hardware. Software patching and upgrades are performed automatically by DBaaS.

The illustration shows how In-Memory DB instances can be created and managed using IONOS CLOUD DBaaS.

In-Memory DB architecture on IONOS CLOUD DBaaS

As shown in the illustration, you can order and manage an In-Memory DB instance using the API. Simultaneously, you can choose the LAN, VDC, and IP address on which In-Memory DB must be available. The IONOS CLOUD DBaaS Backend provisions the In-Memory DB instance according to your request. The primary In-Memory DB instance will be available on your LAN within the VDC and on the chosen IP address after provisioning.

Supported versions

In-Memory DB is compatible with legacy Redis® OSS stable version 7.2.

The IONOS CLOUD DBaaS takes care of minor version upgrades during maintenance windows. For more information, see Upgrade and Maintenance.

Locations

DBaaS for In-Memory DB is offered in all IONOS CLOUD locations. You can use DBaaS instances running In-Memory DB in the IONOS CLOUD infrastructure.

Security

The communication between clients and In-Memory DB is secured using TLS for secure data transmission if your In-Memory DB is set up to use it. For more information about enabling TLS, refer to the In-Memory DB documentation.
