5. Lambda-Less AppSync for SaaS

6. AppSync Direct Integrations
AppSync DynamoDB

7. SaaS Needs a Lambda Function
AppSync Lambda DynamoDB
STS
Custom Authorizer

8. Cross Account Tasks in Step Functions
Step Functions
Task 1
Task 2
Task 3
STS

9. Step Functions With AppSync
AppSync Step Functions DynamoDB
STS
Custom Authorizer

10. •Every tenant must have its own role
•There hard account limits on roles
•Changes to the roles needs to be managed
•DynamoDB mapping isn’t as easy as AppSync’s direct
integration
Things To Be Aware Of

11. Tenant Provisioning

12. How I’ve Done It in the Past
EventBridge Lambda SDKs

13. Problems with This Approach
•Different than what you’re used to (CDK)
•Difficult to see what belongs to a tenant
•Updates are challenging

14. A Better Option
CDK S3 EventBridge Step Functions CloudFormation

20. Multi-Account Tenant Provisioning

21. Cross account role for the task

22. What Didn’t Work with That Approach
•Didn’t allow for rolling deployments
•Multi-account, multi-region,
CloudFormation is complicated!

23. Another Way
CDK S3 EventBridge Step Functions CloudFormation
Account 1
CDK S3 EventBridge Step Functions CloudFormation
Account 2

24. Recap
•Step Functions can be used in tenant specific
workflows in a way that supports data protection
•Step Functions are a great way to manage tenant
specific resources with CDK and CloudFormation
•Managing tenant specific resources in a multi-account
system doesn’t have to be complicated
