Amazon SNS now supports FIFO topics in Canada West (Calgary) region

[Amazon Simple Notification Service (Amazon SNS)](https://aws.amazon.com/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](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-fifo-queues.html) 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](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/standard-queues.html) 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)](https://docs.aws.amazon.com/sns/latest/dg/sns-fifo-topics.html) in the Amazon SNS Developer Guide.
