About AWS Lambda
Lambda runs your code without servers to manage. Upload a function, configure a trigger, and AWS handles scaling, patching, and availability. You pay only when code executes.
Functions respond to HTTP requests, process queue messages, react to database changes—any event can trigger execution. The runtime handles everything except your business logic.
Lambda changed how developers think about backends. Instead of maintaining servers, you write functions and let AWS handle the rest.

AWS Lambda FAQ
Generous free tier: 1 million requests and 400,000 GB-seconds per month forever. Many small applications run entirely within free tier.
Lambda is AWS's serverless compute service. Run code without managing servers. Pay only for compute time used. Scales automatically.
Lambda is serverless with no server management. EC2 gives full control but requires management. Lambda for events and APIs; EC2 for long-running workloads.
Node.js, Python, Java, C#, Go, Ruby, and custom runtimes. Node.js and Python are most popular. Can bring any language via custom runtime.
Cold start is delay when Lambda initializes a new container. Can be 100ms to several seconds depending on runtime. Keep functions warm for latency-sensitive apps.
