Segment.com on cost savings using DynamoDB, autoscaling and ECS
great post.

1. DynamoDB hot shards were a big problem -- and it is terrible that diagnosing this requires a ticket to AWS support! This heat map should be a built-in feature.

2. ECS auto-scaling gets a solid thumbs-up.

3. Switching from ELB to ALB lets them set ports dynamically for individual ECS Docker containers, and then pack as many containers as will fit on a giant EC2 instance.

4. Terraform modules to automate setup and maintainance of ECS, autoscaling groups, and ALBs

Charity Majors - AWS networking, VPC, environments and you
'VPC is the future and it is awesome, and unless you have some VERY SPECIFIC AND CONVINCING reasons to do otherwise, you should be spinning up a VPC per environment with orchestration and prob doing it from CI on every code commit, almost like it’s just like, you know, code.'
