DevOps on AWS
- 2. DEVOPS ON AWS Eric Johnson @edjgeek Rackspace Best Practices AWS Evangelist | Cloud Architect at Rackspace
- 4. 4 DevOps Goal • Continuous Integration • Continuous Delivery Rackspace recommends automated monitoring and response be a part of your DevOps process Automate
- 7. 7 The Serverless Paradigm? • Really, No Servers? • Serverless technologies are Abstracted Services in AWS with API Access only users API AWS Lambda Amazon DynamoDB Amazon RDS Amazon CloudFront Elastic Load Balancing AWS CodePipeline Amazon Lex Amazon Polly Amazon Rekognition Amazon Cognito Amazon API Gateway* Amazon SNS
- 8. Responsibility Model – Infrastructure Services
- 9. Responsibility Model – Abstracted Services
- 10. 10 What Changes? • Release • We no longer release to machines • But we DO release
- 11. 11 A Serverless Stack S3 Hosted Client User Service Customer Service Orders Service Reporting Service Amazon API Gateway* Amazon SNS User Table Customer Table Orders Table Reporting Table
- 14. 14 AWS Serverless Application Model (SAM) • Function • API • Simple Table
- 15. Function Simple Table 15 SAM Examples AWSTemplateFormatVersion : '2010-09-09’ Transform: AWS::Serverless-2016-10-31 Description: A hello world application. Resources: HelloWorldFunction: Type: AWS::Serverless::Function Properties: Handler: index.handler Runtime: nodejs6.10 CodeUri: ./dist AWSTemplateFormatVersion : '2010-09-09’ Transform: AWS::Serverless-2016-10-31 Description: A Simple Table. Resources: HelloWorldTable: Type: AWS::Serverless::SimpleTable Properties: PrimaryKey: Name: id Type: String ProvisionedThroughput: ReadCapacityUnits: 5 WriteCapacityUnits: 5
- 16. 16 Manually Deploying SAM • AWS CLI • CloudFormation ‣ Package ‣ Deploy AWS CLI AWS CloudFormation
- 17. Before Package (service.yml) After Package (.sam/pack.yml) 17 AWS CloudFormation Package (CLI) AWSTemplateFormatVersion: '2010-09-09’ Transform: AWS::Serverless-2016-10-31 Description: A hello world application. Resources: HelloWorldFunction: Type: AWS::Serverless::Function Properties: Handler: index.handler Runtime: nodejs6.10 CodeUri: ./dist AWSTemplateFormatVersion: '2010-09-09’ Transform: AWS::Serverless-2016-10-31 Description: A hello world application.

- 18. Deploy Steps Packaged YAML 18 AWS CloudFormation Deploy (CLI) • Use updated YAML • Create Change Set • Execute Change Set aws cloudformation deploy --template-file .sam/pack.yml --stack-name myStack AWSTemplateFormatVersion: '2010-09-09’ Transform: AWS::Serverless-2016-10-31 Description: A hello world application.

- 19. CodeBuild to the Rescue buildspec.yml 19 Automating the Package Process • Build • Test • Package version: 0.1 phases: install: commands: - echo "Installing dependencies” pre_build: commands: - echo "Tests Running” build: commands: - echo ”Compiling” post_build: commands: - echo "Packaging & uploading to S3” - aws cloudformation package … artifacts: files: - .sam/pack.yml
- 20. Code Pipeline Cft (Partial…) 20 Automating the Deploy • Why not deploy from the CodeBuild? • Deploy from CodePipeline with CloudFormation Name: Deploy Actions: - Name: CreateChangeSet ActionTypeId: Category: Deploy Owner: AWS Provider: CloudFormation Configuration: ActionMode: CHANGE_SET_REPLACE StackName: !Ref Service TemplatePath: BuiltOutput::pack.yml - Name: ExecuteChangeset ActionTypeId: Category: Deploy Owner: AWS Provider: CloudFormation Configuration: ActionMode: CHANGE_SET_EXECUTE
