CLI is the preferred interface for IT professionals as it allows for efficient and precise task execution, along with indexable documentation.

Scripting, not instruction

Combine commands together to enable automation and manage multiple systems simultaneously through copy/paste.

Git repos should serve as the single source of truth for applications, infrastructure, documents, and operations.

Use AWS SAM to develop and deploy automation solutions that integrate both logic and infrastructure.

Cloud and Serverless technologies are integrating infra directly into app development for Dev teams.
