Architecture for Amazon Web Services / AWS

We're planning to upgrade our AWS to more recent hardware. The current setup is EC2 Classic intance-based servers attached to volumes which contain all of the apps data. The concept behind it is that if one of the instance-based servers were lost, we could recreate the server from its AMI and re-attach the volume with the data an be up and running again.

As we upgrade to servers as EC2/EBS volumes (and into a VPC), the risk of server being destroyed is mitigated. Is it worth it just keep all the apps on the new servers and forget about keeping them on attached volumes?

The strategy we used when moving to VPC was to make as few changes as possible. Just launch new servers in a public VPC, nothing else. If you start to change too much at once and encounter a problem, it will be harder to identify the source of the problem because there are so many changes.

For that reason, I recommend keeping your current setup. There might be advantages of a new architecture, but wait until after you've safely migrated to VPC.
