Most applications don’t need a queuing or subscriber service—they need both. With Cloud Queues, you get one API to manage two queue models:
Post messages to a queue, retain those messages for up two weeks, and allow workers to claim and delete them when finished.
Post notifications such as system status and updates to a queue, and allow subscribers to GET messages without claiming them.
Cloud Queues is built off a simple REST API. Here are some basic calls from the Cloud Queues API:
Sign up for the Rackspace public cloud or use your existing account, and provision a Cloud Server (normal charges apply).
Create Queues for producer-consumer or publisher-subscriber models: There is no limit to the number of queues or messages your application can use.
Start posting and claiming messages: See the API documentation for information on message TTL, claim TTL, and other metadata options.
Get fully managed, scalable messaging for your distributed application.
