3. Topics Covered Infrastructure as Code AWS Cloud Development Kit CDK Constructs CDK Stacks Mini-project: URL Shortener service 3 3
4. Infrastructure as Code Process of managing of infrastructure through code instead of manual process. Going throug the AWS Console to create one EC2 instance is tiring enough, imagine doing it for 50 EC2 Instances, a Load Balancer, API Gateways and much much more. Hence, it’s just easier to write down what you want and have AWS do it automatically. 4 4
5. Writing down instructions = code Deploying infrastructure based on instructions = Infrastructure as Code 5 5
6. AWS CloudFormation CloudFormation is the original tool for IaC by AWS. Allows you to define the infrastructure using JSON and YAML. Example of CFN to deploy a WordPress instance 6 6
7. Configuration file based IaC have some drawbacks: 1. It’s hard to write JSON or YAML files 2. The power of a programming language is not utilized Enter CDK, a software development framework with support for Python, Java, JS, TS etc. Better than just declarative config files 7 7
8. CDK Constructs It is the basic building block of AWS CDK applications. Can be a single resource; AWS S3 bucket. Can be higher level abstraction consisting of multiple resources, like Lambda linked to DynamoDB More details and info here and here A construct represents a cloud component and encapsulates eveything AWS needs to create the component 8 8

10. CDK Stacks A unit of deployment in AWS CDK is a stack. A CDK stack is a combination of all the constructs we have defined in our application. cdk ls Allow us to manage all cloud components (ie constructs) as a single unit CDK App <— entrypoint for CDK Stacks <— contain all the constructs (components) 10 10
