needed to manage version control, configuration management, Infrastructure as Code, CI/CD, and observability have drastically increased. This puts an additional burden on the developer as they now must and declared in your Git repo; then your GitOps system will create those for you. OBSERVABILITY Observability from a GitOps perspective is the ability to constantly have access to monitoring the and canary strategies can be also considered as various approaches to progressive delivery. OBSERVABILITY AS A DEPLOYMENT CATALYST An essential component of GitOps is feedback and control. But what is

principles of GitOps, • how your deployment strategy affects your GitOps plan, and • why observability is a critical part of GitOps and how it differs from monitoring Introduction | 04 3 KEY integration / continuous delivery (CI/CD), choosing between pull- or push-based architecture, and observability. Getting Started with GitOps Looking for an In-Depth Introduction to GitOps? Learn the differences mixture of Kubernetes and non-Kubernetes workloads can leverage a combination of both. Robust observability and reconciliation strategies must be thoroughly planned in this scenario, and built-in by design
