Amazon Simple Notification Service (Amazon SNS) now supports FIFO (first in, first out) topics in Canada West (Calgary) region.
You can now use Amazon SNS FIFO topics with Amazon SQS FIFO queues to provide strict message ordering and message de-duplication. The FIFO capabilities of these services work together to act as a fully managed service to integrate distributed applications that require data consistency in near-real time. You can also subscribe Amazon SQS standard queues to SNS FIFO topics, which provide best-effort ordering and at-least once delivery.
To learn more, visit Message ordering and de-duplication (FIFO topics) in the Amazon SNS Developer Guide. To get started, see the following resources:
- FIFO topics example use cases in the Amazon SNS Developer Guide.
- FIFO topics pricing in the Amazon SNS Pricing Page.
