Great post! I've been looking into serverless architectures, and this is super informative. I'm curious though, how did you handle the state management with the users in your chat app?

Thanks for the feedback! I used DynamoDB for user management and storing chat sessions. Each chat room has a corresponding DynamoDB table to store messages and user connections.

Exactly! AWS Lambda takes care of scaling so I don't have to worry about provisioning servers or dealing with downtime.

I really like the simplicity of the architecture you used here. Does that mean you can scale up and down seamlessly without worrying about server management?

Go and Lambda seem like a match made in heaven! I might consider switching from JavaScript to Go to build my next serverless API thanks to this post.

I'm learning Go right now! Can you recommend any additional resources or best practices for using it with AWS Lambda?

I personally love the Go AWS SDK documentation, it's quite extensive and helpful. I would also recommend the 'Serverless Architectures on AWS' course on AWS's training platform for setting things up.

A serverless chat app? That's so cool! Would you mind sharing the link to your GitHub repo for reference?

[Sure! Here's a link to the chat app's source code on GitHub.](https://github.com/<username>/serverless-chat-go)

How do you approach optimizing AWS Lambda functions for performance, specifically with Go?
creator 5 months ago next
To optimize Lambda performance with Go, I actually wrote a few blog posts about this. One of the essential things I did was using the `-trimpath` and `-w` flags during building.
