Elevator Pitch
This talk demos a proven pattern for CDK-based infra as code. Learn to create clear, scalable CFN stacks following 12-factor principles, easily separated by environment in CI/CD. See real-world examples of new Kubernetes API access entries and Karpenter, addressing the lack of practical resources.
Description
This talk presents a CDK implementation pattern inspired by “12 factor app”, focusing on configuration separation and stack modularization.
We’ll address techniques to reduce the complexity of monolithic stacks, applying principles of separation of concerns and allowing environment differentiation through command-line arguments. This facilitates the integration of CDK into common CI/CD environments such as GitHub Actions, GitLab CI/CD, or Harness.
We’ll use the deployment of a VPC, an EKS cluster, and Karpenter, using CDKs to demonstrate the project pattern and structure, covering:
- VPC: Analysis of a 3-subnet architecture and its implementation in CDK.
- CDKs How to pass contexts to Sub Stacks, such as the VPC.
- EKS: New authentication methods with CDK:
- Context transfer between VPC and EKS stacks.
- Migration from ConfigMap to the Access Entries API.
- Implementation of Pod Identities for authenticating kubernetes resources to AWS IAM.
- Karpenter: Advantages in EKS autoscaling, impact on costs and scaling speed.
Notes
Technical requirements: 1. Ability to project code samples 2. Stable internet connection for live demos
Why this talk matters: 1. Addresses common pain points in scaling infrastructure-as-code 2. Provides a proven pattern I’ve used for production deployments 3. Fills gaps in current resources, where most CDK courses and interactive samples are too basic.
