Instance deregistration from ECS clusters

Hello,

I’m happy to announce a new release of AutoSpotting, which now also drains ECS tasks from terminating EC2 instances, making sure no new tasks are scheduled on them and triggering the immediate launch of new replacement tasks by ECS.

You can get it as usual on the AWS Marketplace. This feature is so far only available from CloudFormation but Terraform support will be made available soon, stay tuned.

Another new AutoSpotting release in less than a week

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.

Hello,

Over the years many people asked us to explain the difference between AutoSpotting and standard Autoscaling groups, as well as between AutoSpotting Community edition and the commercial offering on the AWS Marketplace.

We just added this feature comparison matrix on GitHub, so you can easily see how they all compare.

New AutoSpotting bugfix release - 1.3.1

Fixing regressions in 1.3.0: incompatibility with instances out of the DefaultVPC and Lambda timeout when replacing Spot instances

April 29, 2024

Hello,

After releasing AutoSpotting 1.3.0 a couple of weeks ago, I’ve been working with a few customers who noticed a couple of regressions introduced in this latest version:

AutoSpotting failed to launched instances except in the Default VPC (major).
AutoSpotting Lambda timeouts while waiting for terminated Spot instances to be in Running State in case the Grace Period is longer than 2 minutes (medium), resulting in failure to clear suspended ASG. processes**.**

This release is meant to address those and is strongly recommended to users that don’t use Default VPCs for EC2 instances launched by AutoSpotting.

Releasing AutoSpotting 1.3.0(new features) and 1.2.3(important billing bugfix)

After almost 8 months since the previous AutoSpotting release, we’re happy to announce not one, but two AutoSpotting releases at the same time, packed with lots of improvements.

I was hoping to release this much earlier, but somehow each time we got quite close, customers reported yet another little but important edge case that would be be great to fix and then another and so on…

How ECS capacity providers inspired me to fix an ancient AutoSpotting issue

I’m excited to announce that a new version of AutoSpotting is now available.

For some context if you’re not familiar with AutoSpotting, it’s a tool that makes it easy to adopt Spot instances in existing Autoscaling groups, without requiring configuration changes, by replacing their instances with Spot clones using attach/detach API calls.
