Original: The Complete 90-Day DevOps Roadmap I Wish Existed When I Started (Free, No Signup)
Short summary
A detailed 90-day DevOps roadmap structured in five phases: Linux fundamentals, Docker and CI, AWS cloud deployment, Kubernetes orchestration, and job prep. Each layer is ordered so you can debug the layer above it, with 45-60 minutes of daily work totaling ~80 hours. The plan includes hands-on projects using a real FastAPI app carried through each phase, all starting at zero cost on local infrastructure.

- •Ordering principle: each layer must let you debug the layer above it
- •Hands-on projects with a FastAPI app deployed progressively from local Docker to AWS ECS Fargate
