AWS Serverless
This lesson is part of AWS · All levels
Summary
Serverless means you don't have to manage servers: provisioning, patching, and scaling is done by AWS, so teams can focus on code. The model is event-driven and pay-as-you-go, for example AWS Lambda for functions, API Gateway for APIs, and DynamoDB for serverless databases. The concept of cold start and event-based design is becoming important to understand.
Key points
- Without server management and capacity provisioning
- Event-driven with automatic scaling
- Pay per execution or request, not per hour server
- Popular components include: Lambda, API Gateway, DynamoDB, Step Functions, EventBridge
- Cold start is a pause in the initialisation of a function that is temporarily unemployed.
