This will be a use case identification + live coding presentation. - At first we’ll define requirements to build an infrastructure to support development for a _self-sufficient_ team of DevOps engineers: 5 minutes. - We’ll then identify a use-case for AWS Organisational Units, VPC setup with Transit Gateway peering and AWS Codestar connection to an on-premises GitHub server: 10 minutes. - We’ll deep dive into couple use cases to extend AWS CDK with Custom resources to implement the infrastructure: 5 minutes. - We’ll use CDK CLI to deploy the infrastructure to a set of test AWS accounts. We’ll also deploy an AWS pipeline to tie the infrastructure together and will talk about potential next steps to extend this infrastructure: 10 minutes.
