# In-Memory DB

With IONOS Cloud DBaaS, you can quickly set up and manage In-Memory DB, an open-source and in-memory data structure store that stores key-values, and is compatible with the Redis® OSS API. This capability makes it a versatile choice for various applications such as databases, caches, message brokers, or streaming engines.

The IONOS DBaaS offering for In-Memory DB delivers a fully managed service combined with an in-memory cache while also serving as a dynamic real-time database service. This combination leverages memory's rapid access speeds, ensuring high performance. It is particularly well-suited for frequently accessed data that rarely changes, allowing for significant reductions in the load on central databases through efficient in-memory caching.

You can initiate In-Memory DB via the DCD, APIs or automation tools like Ansible and Terraform.
