Deploy OpenStack backend¶
OpenStack is a cloud computing platform that consists of a variety of services, and many of these services rely on backend services like RabbitMQ, MariaDB, and Memcached for their proper functioning. These backend services play crucial roles in OpenStack’s architecture.
RabbitMQ is a message broker that is often used in OpenStack to handle messaging between different components and services. It helps in managing communication and coordination between various parts of the OpenStack infrastructure. Services like Nova (compute), Neutron (networking), and Cinder (block storage) use RabbitMQ to exchange messages and ensure proper orchestration.
Database services like MariaDB are used as the backend database for several OpenStack services. These databases store critical information such as user credentials, service configurations, and data related to instances, networks, and volumes. Services like Keystone (identity), Nova, Glance (image), and Cinder rely on MariaDB for data storage.
Memcached is a distributed memory object caching system that is often used in OpenStack to improve performance and reduce database load. OpenStack services cache frequently accessed data in Memcached, which helps in faster data retrieval and reduces the load on the database backend. Services like Keystone and Nova can benefit from Memcached for caching.
