Launching Instance from the Snapshot

We can use either automated backups or manual snapshots to launch a new instance, but remember we’ll get a new end point.To create a snapshot,select the snapshot and choose the “Snapshot Actions”and choose“Restore Snapshot”option,Then automatically an instance launch wizard will launch.You’ll find almost all same as the regular instance launch.

Creating Read Replicas and promoting them

Read replica’s allow you to have a read only copy of your production database.This is achieved by using Asynchronous replication from the primary RDS instance to the read replica.You use read replica’s primarily for very read-heavy database workloads.

To create a read replica select the Instance Action stab and select the Create Read Replica option

Select the Read replica source and give a name for the replica and choose in what availability zone you want to deploy and even we can select the desired availability zone in the destination region also.

Select the appropriate options and click on Create read replica option.Read replica creation will start and we can see the status in dashboard.

Now read replica is created. To verify the master and slave status we can go to details and verify.

And we can promote the read replica to a standalone db instance, but this breaks the replication.

To promote a read replica,choose the“Promote Read Replica”option from“Instance Actions”

If we want to promote a read replica,we must enable the automated backups and need to select the backup retention period,and you can select the backup window.

We will get a note with the following information

Now the read replica is promoted as an individual db instance and no replication is enabled with any other db instances.
