Many Enterprises struggle with Security and Compliance, I created a book that gives you copy-and-paste Playbook code and solves the most Security challenges, and verify the Compliance of your infrastructure that you could use to save time every day. 

A wealth of knowledge that has been painstakingly assembled to help you on your journey with Ansible

Embark on a journey into the heart of Ansible. Uncover the secrets of efficient automation, troubleshoot with finesse, and elevate your code quality with linting rules. 'Unleashing the Power of Ansible' is your key to mastering IT automation in a world hungry for seamless efficiency. Are you ready to transform the way you orchestrate systems?

Many Linux System Administrators struggle with Ansible, I created a book that gives you copy-and-paste Playbook code and solves the most common errors that you could use to save time every day. 

Build a clear foundation for reliable Ansible automation. Visual explanations connect inventories, playbooks, variables, roles, validation, and safe operations to everyday systems engineering.

This book is not just a Python course with a networking flavour or a networking course with a few scripts attached. You already know how routing converges, why VLANs leak, and what a half-open TCP session looks like on the wire. What this book adds is the ability to transform that knowledge into code that runs across hundreds of devices, reports accurately on its findings and never makes changes that cannot be undone.

Ansible has transformed IT automation, but even the most well-designed playbooks can encounter unexpected errors, cryptic logs, or behaviors that defy expectations. "Ansible Troubleshooting: A Practical Guide" is your roadmap to navigating these challenges with ease. , this book provides the insights and techniques you need to diagnose and resolve issues efficiently.

Most network automation books stop at "here is a playbook that configures a VLAN." This one keeps going — through data models that survive their second year, rollouts that stop at the first device instead of the four hundredth, and the discipline that turns a repository of clever playbooks into something your colleague can run while you are on holiday.

The ultimate practical guide designed to fast-track your technical skills without the fluff. Whether you are a developer, student, or DevOps engineer, this essential reference delivers actionable insights to solve real-world problems instantly. Master your craft and stream-line your workflow today!

In this book, you build a production-grade system with a multi-stage pipeline that compiles, tests, scans, provisions infrastructure with Terraform and Bicep, deploys with zero downtime, validates with Newman, manages packages through Azure Artifacts, and instruments every stage with the security controls that modern AI-era applications require.

Terraform is easy—until teams, compliance, and day-2 reality arrive. This hands-on playbook shows how to scale IaC with GitOps, CI/CD, policy, and operational safety.

I'm writing this in the second half of 2025 soon after retiring with 35 years in software development. I used Salt extensively for the last 7 years, and before that I had been using Puppet for 7 years. I was often involved in tasks that eventually became known as DevOps, mostly focusing on configuration management at smaller companies. I became disillusioned with Salt after the company was sold to VMware which itself was later acquired by Broadcom. Now in late 2025, Salt isn't getting much attention or support from its current owner. Many of the core Salt developers have left the company, and the cadence of bug fixes and releases seem to be slowing down Also before retiring, I looked at the job market and found almost nobody is looking for people with Salt experience while at least some people were still looking for Ansible experience With that in mind, I decided to learn Ansible by porting the Salt states for my home lab over to Ansible. I kept notes along the way, and thought other developers might benefit if I published what I learned.
