Serverless: Code Without Infrastructure

Serverless computing lets you build and run applications without thinking about servers at all—you just upload code, and the cloud provider handles the rest.

"Serverless" is a bit of a trick name—there are still servers, but they are hidden from you. Unlike IaaS (where you manage the server) or PaaS (where you manage the environment), with Serverless (like AWS Lambda), you just manage functions. You upload a snippet of code (e.g., "resize this image"), and the cloud runs it only when needed.

This is the ultimate money saver for random tasks. If nobody uploads an image, you pay zero. If a million people do, it scales instantly to handle it. It kills the need for "always-on" servers. Incorporating serverless functions is a key strategy in our Cloud Development Services to slash your cloud bill while keeping you agile.
