Ecs on AutoSpotting

Releasing Additional Terraform Building Blocks to the LeanerCloud ONCE Bundle

Sun, 02 Jun 2024 00:00:00 +0000

Announcing a new release to the LeanerCloud ONCE bundle, which consists of the Terraform serverless microservice building blocks.

The bundle also contains the Optimizer CLI FinOps tool for GP2 to GP3 conversion for EC2 and EDS, and rightsizing with conversion to Graviton for RDS, Elasticache and OpenSearch, released previously.

These Terraform building blocks are a set of example Terraform modules for building serverless applications using Lambda and ECS Fargate. They will have a slightly different license from the CLI tools, which will allow you to use them to build proprietary products and use within your team, which is not permitted for the CLI tools.

How we maximized task density on our ECS cluster by avoiding burstable instances

And why we had to deploy NAT Gateways in our public subnets

June 28, 2023

As I’ve mentioned in my previous posts, I’ve been recently working with an AI startup to help them optimize their AWS costs.

After quickly doing the basic things like converting EBS volumes to GP3 using EBSOptimizer, right-sized and converted their RDS databases to Graviton and a few other low hanging fruits, the bulk of the work was about converting their individual instances running Docker-compose to ECS.

Why Kubernetes Wasn't a Good Fit for Us

My thoughts on when to Kube or not to Kube…

June 16, 2023

Hello again,

In my previous post I explained the reasons why we ended up choosing ECS instead of Kubernetes for my current LeanerCloud customer.

That post was mostly focused on the customer’s needs and how ECS was a better fit for them.

That blog became pretty viral with over 20k views so far and I received a lot of feedback saying that it was contrarian, and that I should have talked more about where Kubernetes makes sense and why it didn’t make sense for us at this stage.

Why I recommended ECS instead of Kubernetes to my latest customer

And how a cost optimization exercise often leads to deeper modernization of cloud applications

June 08, 2023

It’s been a while since my last post here, and since then I’ve been pretty busy. I’ve been working with an innovative AI startup, helping them optimize their AWS cloud setup. At the same time I’ve been preparing an Udemy course on using ChatGPT for cloud-native software development with a DevOps focus.

In this post I’ll talk about my work with this startup, my thought process and what I recommended them, including the potentially controversial recommendation mentioned in the title.

Another New AutoSpotting Release in Less Than a Week

Fixing ECS load balancer draining

April 15, 2023

Over the last 7 years I’ve been working hard to make AutoSpotting the best solution for running Spot Instances in Autoscaling groups.

Just a few days ago I released our biggest release ever which makes AutoSpotting managed groups of Spot instances even more resilient to low capacity situations than the vast majority of Autoscaling groups configured with a single OnDemand instance type.

As I always keep improving the experience based on user feedback, I just released a new version of AutoSpotting that improves reliability for ECS users, making AutoSpotting with ECS a more highly available solution than plain ECS itself!
