AWS EC2 I3 Instance Types and Storage Persistence

Steve REzhener has a warning for us:

You can see the different types in Fig 1. This blog post is going to talk about a storage optimized instance. the I3 instance type family, its little-known problem, and the solution in the form of  Elastic Block Storage (a.k.a. EBS).
