Summary

In this chapter, we learned that some services in OpenStack are still not fully stateless, thus they require classical clustering methods, such as Pacemaker. We have analyzed in depth the construction of a cluster of services, with their resource agents and dependencies.

We have also learned the step-by-step setting and configuration of load balancing of high availability MySQL and high availability RabbitMQ via AMQP.

In the next chapter, we will have a deeper understanding of how the OpenStack services work in cooperation with each other in a stateless mode to offer a scalable cloud framework.
