Introduction 08 Chapter 1–What is GitOps? Origins in DevOps Kubernetes and containers Cloud-Native DevOps A DevOps Operating Model GitOps Principles Declarative Versioned stored and versioned in Git, and by taking advantage of declarative configurations in Kubernetes. Cloud-Native DevOps So if GitOps isn’t anything new, why are we hearing so much about it now? Much like how technologies have changed the game for DevOps practi- tioners. The ways in which Kubernetes and cloud-native systems manage immutable instances (containers) have allowed DevOps practitioners to further

Serverless is a cloud-native development model that allows developers to focus on building and running applications without project and attract developers to participate. In addition, we should also be active in social networking, such as maintaining social media such as public accounts, publishing quality technical articles

the flexibility of user space programming. Applications User space Kernel System calls Files Networking Process Memory Flying for years across the galaxy and back, The crew learned to modify their to adapt to the evolution of the kernel. Applications User space Kernel System calls Files Networking Process Module Memory One day, a concerned Captain Tux reviewed the crew And remembered that comes from the original Berkeley Packet Filter (used in tcpdump), but now extends way beyond just networking, enabling users to programmatically extend almost any functionality of the operating system.
