Amazon MQ vs CloudAMQP

Amazon MQ is a managed message broker service for Apache ActiveMQ and RabbitMQ. AWS handles broker provisioning, setup, upgrades, operation, maintenance, and failure recovery, while existing broker applications can migrate through standard messaging protocols without rewriting messaging code. Brokers can be launched from the AWS Management Console, CloudFormation, CLI, or API calls. Deployment options include single-instance, replicated-cluster, and active/standby modes, with availability and durability features across Availability Zones. ActiveMQ supports JMS, NMS, AMQP, STOMP, OpenWire, WebSocket, and MQTT, with clients for Java, Node.js, Go, Python, Ruby, and C++. RabbitMQ supports classic, classic mirrored, and quorum queues; quorum queues require RabbitMQ 3.13 or newer. CloudWatch receives broker and queue metrics every minute, and CloudTrail records related API calls. Data at rest uses AWS KMS encryption and broker connections use TLS; TLS 1.3 is unavailable for RabbitMQ brokers. Brokers can run inside an Amazon VPC, with private connections across VPCs and accounts for RabbitMQ. The service supports dead-letter queues, per-queue ordering, and configurable delivery guarantees. It is paid, with an AWS Free Tier plan for eligible new customers for six months; pay-as-you-go broker usage is hourly and storage monthly, with standard transfer fees potentially applying.

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.
