    transformation @ Amazon Modern applications approach Infrastructure as Code Continuous Integration Continuous Deployment Demo Agenda
  4. Development transformation at Amazon: 2001–2002 monolithic application + teams 2001

    Lesson learned: decompose for agility 2002 microservices + 2 pizza teams
  5. Microservice development lifecycle developers services monitor release test build delivery

  6. What changes do you need to make to adopt these

    best practices? Serverless No provisioning/management Automatic scaling Pay for value billing Availability and resiliency Microservices Componentization Business capabilities Products not projects Infrastructure automation DevOps Cultural philosophies Cross-disciplinary teams CI/CD Automation tools DEV OPS Architectural patterns Operational Model Software Delivery
  7. Operational responsibility AWS Lambda Serverless functions AWS Fargate Serverless containers

    ECS/EKS Container-management as a service EC2 Infrastructure-as-a-Service More opinionated Less opinionated AWS manages Customer manages • Data source integrations • Physical hardware, software, networking, and facilities • Provisioning • Application code • Container orchestration, provisioning • Cluster scaling • Physical hardware, host OS/kernel, networking, and facilities • Application code • Data source integrations • Security config and updates, network config, management tasks • Container orchestration control plane • Physical hardware software, networking, and facilities • Application code • Data source integrations • Work clusters • Security config and updates, network config, firewall, management tasks • Physical hardware software, networking, and facilities • Application code • Data source integrations • Scaling • Security config and updates, network config, management tasks • Provisioning, managing scaling and patching of servers

    of releasing modern applications Infrastructure as code
  14. Infrastructure as code (IaC) Declarative I tell you what I

    need I tell you what to do Imperative
  15. IaC goals 1. Make infrastructure changes repeatable and predictable 2.

    Release infrastructure changes using the same tools as code changes 3. Replicate production environment in a staging environment to enable continuous testing
  16. AWS Serverless Application Model (SAM) • Open source framework for

    building serverless applications on AWS • Shorthand syntax to express functions, APIs, databases, and event source mappings • Transforms and expands SAM syntax into AWS CloudFormation syntax on deployment • Supports all AWS CloudFormation resource types github.com/awslabs/serverless-application-model
  17. SAM template AWSTemplateFormatVersion: '2010-09-09’ Transform: AWS::Serverless-2016-10-31 Resources: GetFunction: Type: AWS::Serverless::Function

    Properties: Handler: index.get Runtime: nodejs8.10 CodeUri: src/ Policies: - DynamoDBReadPolicy: TableName: !Ref MyTable Events: GetResource: Type: Api Properties: Path: /resource/{resourceId} Method: get MyTable: Type: AWS::Serverless::SimpleTable Just 20 lines to create: • Lambda function • IAM role • API Gateway • DynamoDB table
  18. SAM CLI: test, package and deploy pip install --user aws-sam-cli

    sam logs sam validate sam local sam init sam build sam package sam deploy sam publish github.com/awslabs/aws-sam-cli
  19. AWS Cloud Development Kit (CDK) • Open source framework to

    define cloud infrastructure in TypeScript, Python, Java, C#, … • Provides library of higher-level resource types (“construct” classes) with built-in AWS best practices, packaged as npm/pip/maven modules • Provisions resources with CloudFormation • Supports all CloudFormation resource types AWS CDK github.com/aws/aws-cdk
  20. CDK template import ec2 = require('@aws-cdk/aws-ec2'); import ecs = require('@aws-cdk/aws-ecs');

    import cdk = require('@aws-cdk/cdk'); class BonjourFargate extends cdk.Stack { constructor(parent: cdk.App, name: string, props?: cdk.StackProps) { super(parent, name, props); const vpc = new ec2.VpcNetwork(this, 'MyVpc', { maxAZs: 2 }); const cluster = new ecs.Cluster(this, 'Cluster', { vpc }); new ecs.LoadBalancedFargateService( this, "FargateService", { cluster, image: ecs.DockerHub.image("amazon/amazon-ecs-sample"), }); } } const app = new cdk.App(); new BonjourFargate(app, 'Bonjour'); app.run();
  21. import ec2 = require('@aws-cdk/aws-ec2'); import ecs = require('@aws-cdk/aws-ecs'); import cdk

    = require('@aws-cdk/cdk'); class BonjourFargate extends cdk.Stack { constructor(parent: cdk.App, name: string, props?: cdk.StackProps) { super(parent, name, props); const vpc = new ec2.VpcNetwork(this, 'MyVpc', { maxAZs: 2 }); const cluster = new ecs.Cluster(this, 'Cluster', { vpc }); new ecs.LoadBalancedFargateService( this, "FargateService", { cluster, image: ecs.DockerHub.image("amazon/amazon-ecs-sample"), }); } } const app = new cdk.App(); new BonjourFargate(app, 'Bonjour'); app.run(); CDK template
  22. 22 Lines 400 lines CDK template import ec2 = require('@aws-cdk/aws-ec2');

    import ecs = require('@aws-cdk/aws-ecs'); import cdk = require('@aws-cdk/cdk'); class BonjourFargate extends cdk.Stack { constructor(parent: cdk.App, name: string, props?: cdk.StackProps) { super(parent, name, props); const vpc = new ec2.VpcNetwork(this, 'MyVpc', { maxAZs: 2 }); const cluster = new ecs.Cluster(this, 'Cluster', { vpc }); new ecs.LoadBalancedFargateService( this, "FargateService", { cluster, image: ecs.DockerHub.image("amazon/amazon-ecs-sample"), }); } } const app = new cdk.App(); new BonjourFargate(app, 'Bonjour'); app.run();
  23. CDK CLI: synthesize and deploy npm install -g aws-cdk cdk

    init app --language typescript cdk synth cdk deploy

    of releasing modern applications Continuous integration
  26. Continuous integration goals 1. Automatically kick off a new release

    when new code is checked in 2. Build and test code in a consistent, repeatable environment 3. Continually have an artifact ready for deployment 4. Continually close feedback loop when build fails
  27. AWS CodePipeline • Continuous delivery service for fast and reliable

    application updates • Model and visualize software release process • Builds, tests, and deploys your code every time there is a code change • Integrates with third-party tools
  28. AWS CodePipeline: Supported sources Pick branch AWS CodeCommit GitHub Pick

    object or folder Amazon S3 Pick Docker tag Amazon ECR
  29. AWS CodePipeline: Supported triggers Amazon CloudWatch Events • Scheduled (nightly

    release) • AWS Health events (Fargate platform retirement) Webhooks • DockerHub • Quay • Artifactory
  30. AWS CodeBuild • Fully managed build service that compiles source

    code, runs tests, and produces software packages • Scales continuously and processes multiple builds concurrently • No build servers to manage • Pay by the minute, only for the compute resources you use • Monitor builds through CloudWatch Events
  31. AWS CodeBuild: Lambda buildspec version: 0.2 phases: build: commands: -

    npm ci - npm test - > aws cloudformation package --template-file template.yaml --output-template packaged.yaml --s3-bucket $BUCKET artifacts: type: zip files: - packaged.yaml

  36. Continuous deployment goals 1. Automatically deploy changes to staging environments

    for testing 2. Deploy to production safely without impacting customers 3. Deliver to customers faster: increase frequency, reduce failure rate
  37. AWS CodeDeploy • Automates code deployments to any instance or

    function • Handles the complexity of updating your applications • Avoid downtime during deployment • Roll back automatically if failure is detected • Deploy to Amazon EC2, Lambda, or on-premises
  38. CodeDeploy – Lambda deployments Enable in your serverless application template
