IronMQ
What IronMQ is
IronMQ is a persistent message queue for communication between services and components in distributed applications. It supports push and pull queues, long polling, error queues, alerts, triggers, and dead-letter queues, with ordering guarantees per queue. Delivery is described as best-effort one-time delivery, a behavior application teams should account for when handling messages.
The service uses HTTPS and REST-based APIs and supports HTTP/REST, Amazon SQS, and OpenStack Marconi protocols. Queues can automatically redirect to alternative availability zones during an outage without code changes. Deployment options are shared, dedicated, and on-premise; the platform listing also includes API, Linux, self-hosted, and web. Iron.io says OAuth and SSL protect data in transit and recommends client-side encryption for especially sensitive payloads at rest. The free Basic plan includes 100K API requests per month, limited queues, and a 64k message-size limit. Entry costs $399 a month; Standard is $799 a month and Premium is $1,249 a month. A full-feature 14-day trial is available only for non-dedicated clusters.
