IronMQ

Key Features

FIFO & Guaranteed One Time Delivery In the put-get-delete paradigm of IronMQ, messages placed on a queue are guaranteed to be delivered once and only once. The first message in is the first message out for when ordering is important to your application. Pull Queues, Push Queues, & Long Polling IronMQ supports a variety of methods of getting messages. Pull queues periodically ask a client to check for messages, push queues inform subscribers when a message is added, and long polling allows you to keep a connection open with a queue until a message has been added. Error Queues & Alerts Messages that do not reach their intended subscriber will be placed on an error queue to be retried until delivery is successful. Place alerts on your queues that notify your systems when they reach a certain number of messages for incorporating actions such as auto-scaling, failure detection, load-monitoring, and system health. Isolated & Private Clusters For advanced users with critical messaging needs, custom environments can be configured. Isolated clusters provide you a cloud service without the crowd. Private clusters are for your queues and your queues only. Automated Region Failover IronMQ is a global service that runs on multiple clouds and availability zones. For advanced users with critical messaging needs, your queues can automatically point to alternative zones in case of an outage without having to change any code.
