Let’s suppose that we have an aws application hosted and that requires 24×7 availability and can be down only for a maximum of 10-15 minutes. How will you make ensure that the database hosted on your ebs volume is backed up properly?
Answer / Ramakant Sachan
To maintain the required availability, you can use Multi-AZ (Availability Zone) deployment, which automatically creates and maintains synchronous standby replicas of your DB instance in a different Availability Zone. Backups can be scheduled using Amazon Database Service (RDS) snapshots that can be set to create on a daily basis or any custom schedule. You should also configure automatic failover to switch to the standby replica if the primary DB instance becomes unavailable.
