# Managed Redis
DuploCloud supports Redis database instances. Redis stands for Remote Dictionary Server and is a fast, open-source, in-memory, key-value data store. Redis can function as a database, cache, message broker, and queue.
Redis delivers sub-millisecond response times, enabling millions of requests per second for real-time applications.
