Learnings From Our Work

What we learn running other people's cloud - cost, migrations, architecture and the failures worth planning for.

Is Spot actually lowering your AWS bill AT ALL?

Surprisingly, the answer could be No Just one of the 5 losses here can reduce savings by HALF! (Hint: its the instance types)

  • Level: Advanced
  • Cost Optimization
  • Compute
  • EC2
  • Spot

Deleted an EBS volume and expected the billing to stop? Maybe not. AWS introduced EBS Recycle Bin and rules could catch it leaving your full volume recoverable. That means that billing continues at the normal storage rate until retention expires or volume recovery. Having a safety net is certainly useful, but left unchecked a wide retention rule could cost you big time. Contact us today to learn about how we can help you tune and optimize cost for your EBS workload.

Are ALB rules costing you money a single config change could save? If you have dozens of ALB listener rules, prioritize the most used ones. If “Rule Evaluations” is your highest LCU dimension, re-ordering the list reduces evaluations, since they stop at the first matching rule.

AWS Cost Optimization Overview

Does cost optimization always have to be a trade off with performance? How do automated agents affect your spend? And most importantly, what kind of ice cream is best paired with cost analysis? Let's find out!

This is a fun, if niche, new ASG feature that will help with API throttling where this workflow is used: https://aws.amazon.com/about-aws/whats-new/2026/08/amazon-ec2-auto-scaling-batch-termination For workloads that need to selectively scale-in specific instances from a central control plane, you can now do that in bulk (100 instances per API call). Every ASG API shares a single throttle bucket, so this API wasn’t viable for larger workloads before. For most use cases, ASG scaling policies work great, and Lifecycle Hooks can be used to gracefully shut down more stateful workloads. But for applications that need it, this is a welcome change! Do you have scaling questions you want to hear more about?
