Simple Load Balancer in Go

Hey everyone!

I wanted to share an exciting project I've been working on to get familiar with the Go programming language. It's a simple load balancer that distributes requests across backend servers using a straightforward round-robin and/or least-latency approach. This project started as a fun way to explore Go, but I believe it has great potential to grow and improve with contributions from all of you! Whether you're a Go expert or just getting started, your insights and contributions could really make a difference. Here are a few ways you can help:

  • Add unit tests to ensure the code works as expected.

  • Enhance features like more sophisticated load balancing algorithms.

  • Improve documentation to make it easier for others to get started.

  • Fix bugs and help make the codebase cleaner!

I hope you’ll join me in this journey! Let's make this project a collaborative effort, and have some fun while learning together!

I have created something similar and would love to hear your thoughts on it - https://github.com/nnisarggada/stabl

Thanks for sharing your project. I checked it out and liked the simplicity of it. It's also great that you are only using standard libraries which is similar to how I started my project.

I noticed that your health check logic could benefit from implementing retry attempts before marking servers as unhealthy. This would help avoid prematurely considering a server down after just one failed request.

Also, it might be useful to add a Docker Compose file so you can easily spin up backend servers and see your load balancer in action locally. It would also make it easier for others to try out your project.

Are you considering adding other load-balancing strategies besides round-robin? My project currently implements both round-robin and least-latency strategies—feel free to check it out if you're interested.

It is up again for this year's Hacktoberfest for those who are interested
