A solutions architect wants to design a solution to save costs for Amazon EC2 instances that do not
need to run during a 2-week company shutdown. The applications running on the EC2 instances store
data in instance memory that must be present when the instances resume operation.
Which approach should the solutions architect recommend to shut down and resume the EC2 instances?

The solution architect should use EC2 hibernation to save costs during the 2 weeks company shutdown. Hibernation preserves the in-memory data & allows the instance to resume with the same state. This avoids the need to manually reload data and only charges for EBS storage while the instance is hibernated. It's a cost effective solution for workloads that require the instance to resume with the same memory state.
