Part 0: Intro, Part 1: Auth and Part 2: CRUD and Part 3: Notification

Introduction

In this part, we would create a CI/CD process using AWS tools. There are a few AWS services for that:

• CodeBuild - continuous integration service.
• CodeDeploy - deployment service.
• CodePipeline - continuous delivery service.

Introduction

An enum type is a special data type which holds a list of constants. Enum type variable must be equal to one of those constants.

• Consumer - processes SQS and sends notifications to the waitees.

Introduction

• CRUD Waitlist - lambda function to handle all the operations on the waitlist.
• CRUD Waitee - lambda function to handle all the operations on the waitee from specific waitlist.

Introduction

We start our dive deep into the architecture from Auth section. To remind you from the previous part it has the next design:
