3. 1. Lambda invoking is often bad.
4. 1. [Problem] sometimes hard to see your logic. packed in.. - Transcribe:StartBatchJob - WaitJobComplete - SNS:Publish - SES:SendEmail - DynamoDB: UpdateItem : return FALLBACK?
5. 1. [Solution] Extract Lambda by SDK integration
6. Eliminate Lambda (as much as possible). Express (and don’t hide) your logic on your StateMachine.
7. 2. The new process and benefit for WorkflowStudio Prototype first. Business logic first.
8. 2. Circulation your workflow Console and Repository
9. 2. Alteration ASL easy on the Workflow Studio (1) Handling all the exceptions.
10. Output modification. 2. Alteration ASL easy on the Workflow Studio (2)
11. Don’t needed write ASL direct. Designing isolated In/Out. Mutually exclusive errors and fallbacks.
12. 3. Point of view for variable injection in CI/CD
13. 3. Pulling variables in the workflow SSM:GetParameters on top of Workflow.
14. 3. Inject variables from AWS-SAM
15. 3. [Recommended Way] Inject variables from AWS-SAM Reset injected values to inside Workflow as variables on top.
16. Refer them as workflow parameters. 3. [Recommended Way] Inject variables from AWS-SAM
17. Manage credential on the single point. Dynamic or static more suitable in your use-case .
18. 4. Design Patterns Exception Handler Catching all exceptions
19. 4. Design Patterns Delaying operation in StateMachine. Delay
20. 4. Design Patterns Run different operation depending on StateMachine input. Action & Choice
21. 4. Design Patterns Avoid StateMachine Nesting with EventBridge. Flatten
22. 4. Design Patterns Real time notification from StateMachine. Async Notification
23. 5. Use case (Shifter, SAML integration workflow)
24. Switch operation per phase in a workflow
27. More traceability comes from SDK integration.
28. Monitoring performance by default with X-Ray.
29. Thanks for listening everyone. See you at the next meetup.
