1. Spot interruptions didn't matter much as AWS Batch looks for spots with low interruption probability. Auto retries kicked-in whenever those did get interrupted.
2. Checkpointing was a pain (we relied mostly on AWS Batch's JobState and S3, not ideal), but the current capability to mount EFS (Elastic Filesystem) looks like it would solve this?
3. No hot swapping on-demand with spot and vice versa. Interestingly, ALB (Application Load Balancer) supports such mixed EC2 configurations (AWS Batch doesn't).
