Hi @sergio-5261, kudos for sharing this here.

It’d be even better if you include a summary or excerpt from the blog post as a hook to get readers excited. The most valuable posts on the Community often thrive on discussions so it’s better we put forward talking points.

I’m curious what led you to AWS Lambda instead of Vercel functions?
