You've likely seen the AWS launch post and are intrigued by what AWS Lambda Managed Instances (AWS LMI) can offer. You may have even read my overview of AWS LMI in an earlier blog post.

In this post, we'll look at AWS Lambda On-Demand costs, how costs change with AWS LMI, when it makes sense to use AWS LMI and when it makes sense to stick with On-Demand AWS Lambda.

You've optimized your Lambda functions six ways from Sunday, but costs are still eating your budget. AWS LMI might help.

You've bought in to using containers to package AWS Lambda functions but now you're curious...

If you had to, could you migrate that same function to AWS Fargate?

You're a Docker pro - or maybe you just work somewhere with strong opinions about how containers should be built. Either way, let's talk about bringing your own container images to AWS Lambda.

You're a Go (or Rust) developer and you're really looking forward to deploying your awesome Lambda application in a OS-only container. Let's look at how to do it.

Your Lambda function just hit the 250MB unzipped size limit.

Again.

You're wrestling with Layers and code dependencies, wondering if there's a better way.

There is — and it might surprise you how simple container packaging makes this problem disappear.

Welcome to the Curious Dev Blog! This is where I'll explore the fascinating world of software development, share insights, and dive deep into the technologies that shape our digital world.
