Failover strategy #7

Closed ArnabRaxit closed 6 years ago

ArnabRaxit commented 6 years ago
  1. ASG with min=max=1 instance
  2. Take a backup of the instance as AMI every 5 mins.
  3. Update launch configuration with latest AMI. ( since AWS doesn't support editing launch configs; create a new one and attach to the ASG)

With this strategy, MTTR is ≈ 4 mins

We are not using ASG/LC now as the application is now backed up on daily basis. And pgdump every two hours (planned). The project team has determined this to be acceptable level of availability for this application.
