CloudAMQP vs Eclipse Mosquitto

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.

Eclipse Mosquitto is a free, open-source message broker for MQTT 5.0, 3.1.1 and 3.1. It uses publish/subscribe messaging, a pattern suited to connected devices such as sensors, phones, embedded computers and microcontrollers. The project describes it as lightweight, with applications from low-power single-board computers to full servers. Mosquitto runs on Linux, macOS, Windows and self-hosted environments. The project also provides a C library for MQTT clients and the mosquitto_pub and mosquitto_sub command-line tools. MQTT and MQTT over WebSockets are supported, and delivery guarantees are configurable. A public test server offers plain MQTT, TLS, client-certificate TLS and WebSocket options. The project lists manufacturing, healthcare, automotive and smart-home systems among broker application areas. Community support is best effort through GitHub, a mailing list, Matrix and Cedalo forums. Cedalo offers hosted or on-premises instances, consulting and custom development.
