Automating Infrastructure with AWS CDK

Transcript

1. Presented by Rumesh Hapuarachchi Automating Infrastructure with AWS CDK
4. Infrastructure as Code
5. Infrastructure as Code Repetable & Predictable Same tools as your code Replicating environments for better testability
7. AWS Cloud Development Kit (AWS CDK)
8. Engineers love coding • Languages which they already know • Java, JS, TS, Python, Go, C# • Existing tools & workflows • Abstractions • Libraries • Use logics when defining your infrastrucure
11. From code to cloud "Source" "Compiler" "Assembly Language" "Processor"" synthesize deploy AWS CF CF Template CDK CLI
12. AWS CDK Main Components • Core Framework (App, Stacks, Resources) • AWS Construct Library • AWS CDK CLI
13. Construct Levels Image Credits: Sebastian Korfmann
14. 99x.io npm install -g aws-cdk
15. Commands • cdk init • cdk synth • cdk diff • cdk deploy • cdk destroy
16. Let's Build Our First App
17. 99x.io Testing?
18. Isn't that same as Jest? Testing with CDK • Snapshot tests • Fine-grained assertions • Validation tests
19. Show me some code?
20. Best Practices • Layer your application to reduce blast radius • Use multiple, isolated environments for dev, test, stage and prod • Smaller files • Make use of Parameter Store and Secrets Manager • Do not overengineer
21. Helpful Resources • https://cdkpatterns.com/ • https://github.com/cdk-patterns/serverless • https://docs.aws.amazon.com/cdk/api/latest/docs/aws- construct-library.html
