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.
