Amazon ECS Managed Instances 🚀☁️ #88

AppSync and a lot of takes on Security....

Oct 15, 2025

In the previous issue, Messaging and integrations 🚀☁️ #87, we looked into the updates with the integrating services - EventBridge, MSK, SQS, SNS.

In this issue, let’s see what the new Amazon ECS Managed Instances are!

Tired of choosing between operational simplicity and infrastructure control? In this issue, we dive into Amazon ECS Managed Instances, the new compute option that brings you the best of both worlds. Discover how this service provides a fully managed, auto-scaling EC2 infrastructure for your containers while still giving you the flexibility to select the right instance types for your unique workloads. Say goodbye to manual patching—your infrastructure maintenance and security updates, powered by Bottlerocket, are now on autopilot, making it one of the most cost-optimized and hands-off ways to run ECS.

Also, you can see some interesting thoughts and takes on ECS Managed Instances on the LinkedIn post.
