Amazon SNS now supports FIFO topics in five additional regions

You can now use Amazon Simple Notification Service (SNS) FIFO topics in five additional AWS Regions: Asia Pacific (Hyderabad), Asia Pacific (Melbourne), Europe (Spain), Europe (Zurich), and Middle East (UAE). You can use Amazon SNS FIFO topics, in combination with Amazon Simple Queue Service (SQS) FIFO queues, to build applications that require messages to be sent and processed in a strict sequence and without duplicates.

Amazon SNS is a fully managed, reliable, and highly available pub/sub messaging service that enables you to decouple microservices, distributed systems, and serverless applications. Both Standard and FIFO topics support publishing messages in batch and fanning out messages to multiple subscriptions with high durability, filtering, encryption, and privacy, while FIFO topics provide the added benefit of ordering and deduplication of messages. Using Amazon SNS FIFO topics and Amazon SQS FIFO queues together, you can build modern applications that leverage a publish/subscribe architecture without writing custom code for message ordering and deduplication.

You can start using FIFO topics today, via the AWS Management Console, AWS Software Development Kit (SDK), Amazon SNS Command Line Interface (CLI), and the Amazon SNS Application Programming Interface (API). You can also provision FIFO topics via AWS CloudFormation.
