Amazon EC2 migration from one region to the other
- by Gnanam
I'm using the following Amazon EC2 resources in the US East (Virginia) region:
1 Running Instance
1 Elastic IP
2 EBS Volumes
100 EBS Snapshots
1 Key Pair
2 Security Groups
5 My Own AMIs (customized based on
my application stack)
My instance is based on Linux distribution (CentOS) and my AMIs are S3-backed. Both EBS volumes are mounted on this running instance.
We're planning to migrate our deployment to US-West region. Because Amazon EC2 resources are not shared across regions, my questions are:
What are all the factors that I need to consider in advance?
What are all the recommended & different ways of migrating each EC2 resources from one region to the other?
Are there any hidden risks involved during and/or after the migration?
Experts ideas/suggestions/recommendations on this are highly appreciated.
