IaC on AWS Cloud
- 1. Indore, India IaC on AWS Bhuvaneswari Subramani | 3rd July 2021 https://bhuvana.pro/ /bhuvanas @installjournal
- 2. Agenda • Infrastructure as Code on AWS • AWS CloudFormation • AWS Serverless Application Model (SAM) • AWS CDK (CDK) • IaC Solutions in AWS Marketplace
- 3. Infrastructure as Code on AWS
- 4. Managing Infrastructure as Code SOURCE Developers commit changes BUILD Changes are built STAGING Code is deployed and tested PRODUCTION Developers commit changes AWS CodeCommit AWS CodeBuild Third Party Tooling AWS CodeDeploy AWS CodePipeline AWS CodeDeploy
- 5. IaC Tools AWS CloudFormation Terraform AWS Serverless Application Model Ansible AWS CDK chef puppet c
- 6. Apply DevOps Principles to IaC
- 8. AWS CloudFormation • Create and provision AWS infrastructure deployments predictably and repeatedly • Resources are written in text files using JSON or YAML format. Use Cloud9 or your favorite editor • Version Control the template • Helps build the specified services in safe, repeatable manner
- 9. AWS CloudFormation Template Stack Parameters Mappings Resources Outputs Template Parameter Values Create / Update sync Env => Test / Prod
- 11. AWS CloudFormation Template Anatomy JSON vs YAML Except resources all sections are optional
- 13. CI / CD for Infrastructure & WebApp Source Build Deploy
- 14. Pipeline view of Infra Rollout + Web App Deployment
- 15. AWS Serverless Application Model (SAM) c
- 16. AWS Serverless Application Model • AWS CloudFormation extension, optimized for serverless • AWS SAM is supported directly by AWS CloudFormation • YAML or JSON • Supported Resources • Api, Application, Function, HttpApi, LayerVersion, SimpleTable, StateMachine c
- 17. AWS SAM Template Anatomy • Transform declaration Transform: AWS::Serverless-2016-10-31 • Globals section AWS::Serverless::Function, AWS::Serverless::Api, etc. • Resources section Combination of CloudFormation & AWS SAM resources • Parameters section Objects declared in Parameters section cause SAM deploy
- 18. AWS SAM CLI • CLI tool for local development, debugging, testing, deploying, and monitoring of serverless applications • Supports API Gateway “proxy-style” and Lambda service API testing • Response object and function logs available on your local machine • Uses open-source docker-lambda images to mimic Lambda’s execution environment • Can tail production logs from CloudWatch logs • Can help you build in native dependencies
- 19. AWS SAM CLI Commands • sam build – install dependencies • sam deploy – deploy AWS SAM application with AWS CloudFormation • sam init – initialize a serverless application • sam local: • generate-event– generate sample payloads from event sources • Invoke invokes a Lambda function once • start-api – set up local endpoint to test your API • start-lambda – start a local endpoint to test your local lambda • sam logs – fetch logs for a function • sam package – package an AWS SAM application • sam publish – Publish an AWS SAM application to the AWS Serverless Application Repository • sam validate – Verifies whether an AWS SAM template file is valid
- 20. CI / CD for Lambda Deployment using AWS SAM
- 21. AWS CDK (CDK)
- 22. AWS CDK • AWS CDK to define your cloud resources in a familiar programming language • AWS CDK supports TypeScript, JavaScript, Python, Java, C#/.Net, and (in developer preview) Go • Define reusable cloud components known as Constructs • Compose Constructs together into Stacks and Apps
- 23. AWS CDK
- 24. AWS CDK Development Workflow Create App Add Code Build Synthesize Deploy
- 25. AWS CDK Development Workflow Create App Add Code Build Synthesize Deploy Add code to the app to create resources within stacks Build the app Synthesize stack(s) in app to create AWS CloudFormation template Deploy stacks to your AWS account
- 26. AWS CDK Toolkit The AWS CDK Toolkit is a command line tool for interacting with CDK apps • cdk lists (ls) – Lists the stacks in the app • cdk synthesize (synth) – Synthesizes and prints the CloudFormation template for the specified stack(s) • cdk bootstrap – Deploys the CDK Toolkit stack • cdk deploy - Deploys the specified stack(s) • cdk destroy - Destroys the specified stack(s) • cdk diff – Compares the stack with deployed or local CloudFormation template • cdk metadata – Displays metadata about the specified stack • cdk init – Creates a new CDK project in the current directory from a specified template • cdk context - Manages cached context values • cdk docs (doc) – Opens the CDK API reference in your browser • cdk doctor - Checks your CDK project for potential problems
- 27. IaC Solutions in AWS Marketplace
- 28. IaC Solutions in AWS Marketplace
- 29. Key benefits of using solutions from AWS Marketplace
- 30. Key Take Aways AWS CloudFormation AWS Serverless Application Model AWS CDK c Better together: AWS SAM and AWS CDK
