3. The Experiment • Small project • Not much previous AWS experience • Keep costs low • Learn about AWS PaaS offerings?
4. The Constraints • Only AWS • Only Paas • No Frameworks
5. The Project • Provide a service to calculate a user score based on events - Think StackOverflow
6. Let’s get going… • I want to define my first couple of API endpoints, what are my options? API Gateway
7. Quickly Produce a Mocked Endpoint Request: GET https://**yourapi**.execute-api.eu-west-1.amazonaws.com/Test/user/id/1/score Response: { “userId”: “1”, “score”: 2 }
8. I Think I’m Ready to Automate AWS CLI CloudFormation • Bash script • Procedural • Desired state configuration • Declarative
9. CloudFormation
10. Provisions What do we have so far? API Gateway CloudFormation $ aws cloudformation deploy --template-file cfTemplate.yml \ --stack-name score --capabilities CAPABILITY_IAM GET https://**yourapi**.execute-api.eu-west-1.amazonaws.com/Test/user/id/1/score
11. Make It Do Something! API Gateway Lambda Execute
12. CloudFormation Serverless Application Model
13. CodePipeline CodeBuild CloudFormation GitHub CodePipeline S3
