IronMQ vs TIBCO FTL

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, and triggers, as well as dead-letter queues and ordering within each queue. Delivery is described as best-effort and one-time, a behavior application teams should account for in message handling. Its HTTPS and REST-based APIs support HTTP/REST, Amazon SQS, and OpenStack Marconi protocols. During an outage, queues can automatically point to alternative availability zones without code changes. Deployment options include shared, dedicated, and on-premise environments. Documentation lists client libraries for Go, Ruby,.NET, Java, PHP, Python, Node, and Rust, plus community-supported Apache Camel and Clojure libraries. 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; a full-feature 14-day trial is offered for non-dedicated clusters.

TIBCO FTL is an application-to-application messaging system designed for low latency and high performance. Applications can exchange messages through brokers or directly with one another using peer-to-peer messaging. Messages contain named fields with typed values, and subscribers can use content matchers to select them. Persistence services retain messages for durable subscribers and replicate message and acknowledgement data across services for fault tolerance. API references are listed for C,.NET, Java, and Go; TIBCO also describes messaging for REST, web, and mobile-based devices. Security documentation covers authentication, authorization, TLS, secure transports, and server data directories. FTL channels enable publish-subscribe messaging among eFTL applications and between eFTL and FTL applications. Listed platforms include API, Linux, macOS, self-hosted, web, and Windows. The Community Edition is listed at free. Enterprise Edition pricing is on request, and a non-expired license is required to start it. TIBCO lists online support cases and live chat available around the clock for other assistance.
