AWS SQS

You can use a SQS rule to send data such as messages, occupancy, lifecycle and presence events from Ably to SQS. 

Queues are a mechanism for customers to consume, process, store, augment or reroute data from the Ably platform efficiently to your servers. The queue messaging pattern provides decoupling (publishers can publish without waiting for consumers), scalability (adding more consumers increases throughput capacity) and resilience (messages are stored until a consumer has acknowledged the message has been processed successfully.

Message queues are common for managing tasks and workloads where you only require each task to be processed once. 

You can set up rules with Ably that can publish messages to external queuing services such as AWS SQS.
