Series Introduction – From Automation to AI: A Practitioner's Journey

From Automation to AI – A Practitioner’s Journey

This series documents my journey of learning Artificial Intelligence from the perspective of a Solution Architect working on:

• Automation frameworks
• Infrastructure as Code (Terraform / Ansible)
• DevOps and CI/CD platforms
• Cloud Management Platforms (CMPs) and self-service catalogs

The goal is not to become a data scientist.

The goal is to understand:

• Where AI fits in modern architectures
• How AI complements automation and IaC
• How to design, integrate, and govern AI-enabled platforms

This is a learning journal and a practical reference—written for my future self and for engineers walking a similar path.

Who This Series Is For

This series is intended for:

• Solution architects
• Automation and platform engineers
• DevOps and IaC practitioners
• Engineers building self-service or CMP platforms

If you already work with:

• Pipelines
• Desired state
• Guardrails
• Scale and governance

You are the intended audience.
