Overview
Serverless does not mean 'no servers,' but rather that developers do not manage the underlying infrastructure. Code is executed in response to events, and the system scales resources automatically.
Key Features
- No Infrastructure Management: No need to provision or patch servers.
- Automatic Scaling: Scales up or down (including to zero) based on traffic.
- Pay-as-you-go: Billing is based on actual execution time and frequency.
