Apache Qpid Broker-J vs CloudAMQP

Apache Qpid Broker-J is free, open-source Java message-broker software for self-hosted deployments. It stores, routes and forwards messages using AMQP, supporting versions 0-8, 0-9, 0-9-1, 0-10 and 1.0, plus AMQP over WebSockets. Administration is available through REST, AMQP Management and a web console. Routing and queue features include header-based routing, message groups, server-side selectors, dead-letter queues, and last-value, priority and sorted queues. Pluggable persistence supports Derby, SQL and BDB stores. Listed operational features include high availability, producer flow control and flow to disk. Authentication can use LDAP, Kerberos, OAuth2 or SSL client certificates; access control lists and SSL secure connections are supported. The listed current release is 10.1.1, with source archives and tar.gz or zip binaries. Installation documentation covers Windows and UNIX systems. The project uses Apache License 2.0.

CloudAMQP is a managed cloud service for LavinMQ and RabbitMQ messaging clusters. It automates cluster setup, operation, and scaling, with a control panel for monitoring and alarms sent through email, webhooks, or external services. Plans support AMQP, AMQPS, HTTPS, STOMP, and MQTT; dedicated plans also support WEB-STOMP. The service runs on Amazon Web Services, Google Cloud Platform, Microsoft Azure, DigitalOcean, and Scaleway. It supports configurable delivery guarantees, per-queue ordering, dead-letter queues, and messages up to 128 MB. RabbitMQ clusters use Quorum Queues to replicate messages across nodes and reconnect clients after a node failure. SSL/TLS protects data in transit, with network isolation and VPC options on some clouds. CloudAMQP states that it is SOC 2, GDPR, and HIPAA compliant. Free plans are available; paid plans start at $19/mo. Customers cannot access nodes via SSH.
