Disaster recovery on EC2
Protecting your mission-critical EC2 instances from long-term or permanent outages in the AWS Regions that host your cloud workloads doesn't have to be a difficult task. In this blog, I will show you how to replicate and failover his EC2 instances across regions.
Indicates that the instance was launched in Northern Virginia.
- Create a clone instance from the same AMI in another region.
- Snapshot primary instance volume
- Copy snapshot to DR region
- Create a volume from the replicated snapshot
Note: It is important to select the same availability as your instance
- Detach the volume from the instance and attach the volume created from the snapshot to the DR instance.
Note: Be sure to stop the instance before detaching the volume.
