13. HBC 2018 microservice architecture multi-tenant services increased adoption of AWS Lambda safe deployments
15. HBC email types • order acknowledgement • order shipment partial • order shipment full • order cancel • ready for pickup in store
16. Queue consumer Event queue Email Dashboard UI Email Sender Email Render External Email Provider Feature Flag service
17. Email Render Product Detail service Delivery Date Estimation service request HTML Feature Flag service
18. HBC email system • multi-tenant design • Cloudwatch Metrics • Cloudwatch Alerts
19. HBC email system • code coverage threshold • components deployed independently • safe deployments
20. aws-cli
21. $ brew install aws-cli

33. Traffic Shifting
34. You can now shift incoming traffic between two AWS Lambda function versions based on pre-assigned weights. You can now also use AWS CodeDeploy to automatically manage the rollout of new function versions. This allows you to gradually shift traffic between two versions source: aws.amazon.com
35. Traffic Shifting configurations AllAtOnce Canary10Percent30Minutes Canary10Percent5Minutes Canary10Percent10Minutes Canary10Percent15Minutes

39. Traffic Hooks
40. AWS traffic hooks • PreTraffic hook • PostTraffic hook
41. AWS CodeDeploy UI https://console.aws.amazon.com/codesuite/codedeploy/deployments
42. https://github.com/awslabs/serverless-application-model/pull/605
43. Future work at HBC additional validation logic in Pre Traffic hook implement Post Traffic hook utilize AWS Cloud9 IDE
44. Final thoughts
45. traffic shifting
46. small incremental releases
47. engineering velocity is a competitive advantage
48. The end
