RabbitMQ for PCF
RabbitMQ for PCF enables PCF app developers to provision and use the RabbitMQ message broker with a single command.
RabbitMQ for PCF v1.8 supports two types of service, an on-demand service and a pre-provisioned service. This table summarizes the main differences between the two:
|Available Since||VMs it Runs On||How VMs are Created||Metrics Name Prefix|
|On-Demand Service||New for v1.8||Dedicated VM that serves a single service instance||PCF creates each VM on-demand when app developer creates service instance||
|Pre-Provisioned Service||v1.2||Multi-tenant VMs shared by apps across PCF deployment||PCF creates all VMs when operator deploys or updates service||
This RabbitMQ for PCF v1.8 documentation describes both service types. Documentation for RabbitMQ for PCF v1.7 and earlier only describes a pre-provisioned service.
For PCF RabbitMQ versions before v1.8.0, the RabbitMQ Service instances correspond to a unique RabbitMQ Vhost on the multi-tenant RabbitMQ cluster. RabbitMQ for PCF v1.8.0 introduced On-Demand Broker (ODB) support. That means that a new, single-tenant, cluster can be created and dedicated to a single app.
RabbitMQ is a fast and dependable open-source message server, which supports a wide range of use cases including reliable integration, content-based routing and global data delivery, and high-volume monitoring and data ingestion.
Emerging as the de facto standard for cloud messaging, RabbitMQ is used for efficient communication between servers, applications and devices, and creates lasting value by enabling rapid development of modern decentralized application and data architectures that can scale with your business needs.

- Cannot scale-out if Erlang Cookie is not specified
- Changing Erlang Cookie value results in failed deployment
- IPsec does not work with this version of the tile and it must be installed into a non-IPsec subnet or by excluding the deployment IPs following the steps in the documentation
- As of Ops Manager v10.0.0, errands set to the When Changed rule do not always run when the tile has relevant changes. One-time rules should be set when using Ops Manager 1.10.7 or earlier to ensure that Update All Service Instances is run.
