1. I have a microservice which pushes the messages to the SQS Fifo queue. If in future the SQS is down, How can I configure a secondary SQS as a failover. Could also please mind in explaining how AWS manages the high availability of SQS.

2. IS SQS a region based service or an Availability-zone based service.

CodePudding user response：

You can read the SLA here. SQS is regional, and highly-available within each region.

Here's a guide to Disaster Recover on SQS, which provides suggested architectures for:

1. Active-Active
2. Backup & Restore
3. Pilot Light
4. Warm Standby
