Principal Cloud & Platform Architect with 15+ years of experience designing, building and operating cloud-native platforms in enterprise and scale-up environments. I specialize in Kubernetes platforms, GitOps delivery models and secure infrastructure foundations across AWS, Azure and GCP. My focus is on creating scalable, reliable platforms that enable engineering teams to deliver autonomously while reducing operational risk and long-term complexity. I work at the intersection of architecture, reliability and enablement, supporting both technical teams and leadership in making pragmatic, long-term infrastructure decisions. I am a CNCF Golden Kubestronaut, reflecting deep, end-to-end expertise in Kubernetes operations, security and platform engineering. Currently open to strategic roles and missions involving cloud platform architecture, Kubernetes foundations, GitOps transformations and infrastructure reliability. https://speakerdeck.com/ocalzi 2026-04-17 12:14:05 -0400 This AMA will give attendees a candid look at the CNCF certification journey — the wins, the struggles, and the strategies that really work. By sharing my own path to Kubestronaut and answering live questions, I’ll help demystify certifications and give the community practical insights they can immediately use in their own growth.

It is a lack of infrastructure knowledge. You can write perfect code, but if you don't know how to securely deploy, scale, and manage it in a modern cloud environment, global enterprises simply cannot hire you. For Open Source Connect Session 11, we are fixing this. I am hosting Olivier Calzi, a Senior SRE in Europe and a Cloud Native Computing Foundation (CNCF) Golden Kubestronaut. Olivier has spent 15+ years designing enterprise-scale platforms, and he has agreed to give our community a step-by-step masterclass tailored explicitly for absolute beginners. If you are looking to break into Platform Engineering or DevOps in 2026, save this post so you don't lose this roadmap. Here is what we are unpacking: 1. The "Shift Left" Mindset: Why modern development requires you to understand CI/CD pipelines and declarative infrastructure from day one. 2. The Certification Pathway: Not all certs are created equal. Olivier will explain why the KCNA and CKA are the most trusted indicators of real skill. 3. The AI Infrastructure Link: How mastering container orchestration (Kubernetes (Official)) is the prerequisite for scaling modern AI applications.
