-==== Clustering or not clustering? ====
-When deploying RabbitMQ, you have two possibility:
-* Deploy rabbit in a cluster
-* Deploy only one rabbit node
-Deploying only one rabbit node can be seen as dangerous, mostly because if the node is down, your service is also down.
-On the other hand, clustering rabbit has some downside that make it harder to configure / manage.
-So, if your cluster is less reliable than a single node, the single node solution is better.
-Moreover, as many OpenStack services are using RabbitMQ for internal communication (a.k.a. RPC), having a highly available rabbit solution is a must have.
-==== One rabbit to rule them all? ====
-You can also consider deploying rabbit in two ways:
-* one rabbit (cluster or not) for each OpenStack services
-* one big rabbit (cluster or not) for all OpenStack services
-There is no recommendation on that part, except that if you split your rabbit in multiples services, you will, for sure, reduce the risk.
-=== Which version of rabbit should I run? ===
-You should always try to consider running the latest version of rabbit.
-We also know that rabbit before 3.8 may have some issues on clustering side, so you might consider running at least rabbitmq 3.8.x.
