How can we combine CloudFormation and Beanstalk?

• CF has a beanstalk resource type.
• Slam beanstalk into your CF templates

How do we prevent RDS data loss when beanstalk deleted?

• Decouple RDS instances from beanstalk app; launch separately
• Mod inbound rules to allow access from beanstalk to RDS

Can we use CDK instead of CF?

• Sure, it’s more concise if you prefer Python / TypeScript etc
• It still resolves to CF under the hood

Which deployment targets can we use with CodeDeploy?

• ec2
• on-prem
• lambda
• ecs

How do we avoid reinventing the wheel in the CDK?

• Use AWS Construct Library

Can you do serverless stuff in the CDK?

• Yes, or use SAM, it’s a similar vibe
