Understanding the Serverless Execution Model
Dive into how serverless functions actually run: invocation models, cold starts, concurrency, and the stateless nature of functions.
Functions as the Unit of Compute
In serverless, the function is the unit of deployment and scaling. The platform provisions compute only when an event arrives, and scales to zero when idle.
Event-Driven Invocation
Functions run in response to events — an HTTP request, a queue message, a file upload, a schedule. The event payload lands in your handler.
