## What the paper covers

- ### What Auto Mode Changes

  Who runs nodes, scaling, networking and storage, from the AWS shared responsibility model
- ### Managed or Self-Hosted Argo CD

  When the EKS Capability for Argo CD fits and when to run it yourself
- ### Open-Source Platform Stack

  SigNoz, Falco, Trivy and External Secrets Operator, deployed through GitOps
- ### Migration One Application at a Time

  Strangler pattern, a pitfalls table and a DNS rollback plan for every application
- ### Cold-Standby Disaster Recovery

  A second region defined in code, with recovery targets set from a timed drill
- ### Worked Cost Example

  Control plane, EC2 and the Auto Mode fee, worked from AWS list prices
