Functions as a Service

← Back to Serverless

The core serverless compute model where developers deploy individual functions that the cloud provider executes on demand. AWS Lambda, Google Cloud Functions, and Azure Functions are the major FaaS platforms. Functions are stateless, short-lived, and billed per invocation and execution duration.

Key Properties

• AWS Lambda
• Cloud Functions
• Per-Invocation Billing
