Foreword
Having been a hero for IT organizations, I realize the battles that are waged to sustain the systems we take for granted. They are the enduring talent that knows the exact script to run, or commands to execute, to bring back our desired apps. That life is one that puts family and self care on the back burner due to the impact of constant weekend and evening escalations. Enlightenment and healing come from effective software engineering practices such as GitOps. Talent heroics is perpetuated by the belief that tasks themselves matter more than the value they create. GitOps supports the idea that an SME can create a process whereby the outcome is attained, consistently, without their direct involvement or loss of valuable time. Once you realize the scaling and sustainability that brings, you begin to focus on self-development and continuous improvement. GitOps is the practice of leaving behind worthy evidence of your passage at an organization, building process-based outcomes, using the skills that make you an SME, that persist beyond your move to bigger, more valuable challenges. Sustaining systems, creating services, based on very effective code-based processes. This book is targeted at those individuals in the hope that it will provide them a well-articulated path for enlightenment and healing from their talent heroism.
– Shlomo Bielak (CTO at Benchmark Corp)
