Chapter 13 Serverless Applications Flashcards
Endpoint types for API Gateway
- Regional endpoints: inside AWS region
- Edge Optimized Region: connection points via CF edge locations
- Private Endpoints: only live inside a VPC
For API Gateway, what is a ‘stage’?
A named reference to a deployment, which is a snapshot of the API.
What is a canary release?
When you launch a deployment and allow original deployment to remain. Only a small portion of traffic is routed to the new deployment.

2. three
AWS SAM is an extension of ______
AWS Cloudformation.
SAM is beneficial because it allows you to easily tie Lambda functions with a SAM specific concept called an ‘event’. This event could be something like an API Gateway endpoint.
Three main benefits of serverless model
- no server management
- flexible scaling
- automated high availability
How to secure your APIs with API Gateway?
Use Gateway to setup authorizers with Amazon Cognito user pools on an AWS Lambda Function
