☁️ Serverless Architecture Simulator

Visualize Lambda cold starts, auto-scaling, and pay-per-invocation in real time

🤔 What Is Serverless Computing?

Serverless computing lets you run code without provisioning or managing servers. When a request arrives, the cloud provider spins up a container, executes your function, and tears it down when idle. Cold starts happen when a new container must initialize from scratch (slow); warm starts reuse an existing container (instant). You pay only for actual execution time.

Why does this matter? Serverless architecture powers modern applications from APIs to data pipelines. AWS Lambda alone processes trillions of invocations per month. Understanding cold starts, concurrency limits, and cost optimization is essential for building efficient cloud-native systems.
