Serverless in 2025 — What I’ve Learned

I spent the last few weeks moving parts of an internal web app to serverless, and it’s been both freeing and frustrating.

The freeing part is obvious — I don’t patch servers anymore, scaling happens automatically, and I can focus on features instead of infrastructure. That speed of iteration is game-changing.

The frustrating part? Debugging async chains in Lambdas, unpredictable cold starts, and vendor quirks. It’s not magic — complexity just moves around.

For new applications — APIs, event-driven workloads, or projects with spiky traffic — serverless is a huge win. Deployment is faster, teams can focus on product, and operational overhead is significantly reduced.

For legacy systems, long-running jobs, or compliance-heavy applications, traditional architectures still make more sense. The key isn’t choosing a “better” model, it’s understanding which approach fits your project and your risk tolerance.

Serverless isn’t hype anymore. In 2025, it’s a standard tool in the toolkit, and knowing when and how to use it makes a real difference in web application development.
