Introduction 08 Chapter 1–What is GitOps? Origins in DevOps Kubernetes and containers Cloud-Native DevOps A DevOps Operating Model GitOps Principles Declarative Versioned Software-as-a-Service (SaaS) company that hosted applications on their platform using Kubernetes as the infrastructure layer managing the applications. One day there was an incident where a configuration 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

Introduction GitOps has gained popularity in the cloud-native ecosystem, particularly in Kubernetes-based environments, where managing infrastructure as code operational framework that aims to streamline and automate the deployment and management of applications and infrastructure using Git as the single source of truth. It simplifies and standardizes the teams, and increases the reliability and reproducibility of deployments. GitOps is popular in the cloud-native ecosystem, particularly in Kubernetes-based environments, where managing infrastructure as code

In this Refcard, we will dive into what GitOps means in the Kubernetes world, key principles, and the advantages for cloud-native ecosystems. and tweaks would be taken care of by an automated mechanism.

The openEuler open source community was officially established on December 31, 2019, with the It enhances server and cloud computing features, and incorporates key technologies including cloud-native CPU scheduling algorithms for hybrid service deployments and KubeOS for containers.

that enable them to be more productive and deliver applications more quickly. The tools and services that developers need to build and ship applications are what make up the developer experience (DX). Crafting to them whenever needed. Application development teams Application development teams deliver applications and products to end-users. These teams are aligned according to the organization’s priorities consistent way to build and deliver applications from on-prem to edge. Deutsche Telekom is a great example of an organization that needs to support legacy applications and extend them with cloud capabilities

can find the operations side tricky when they’re trying to spin up infrastructure on modern, cloud-native technologies. They need a way to confidently and securely deploy changes to Kubernetes that doesn’t how to deploy, configure, monitor, update, and manage Kubernetes, it components, and all the applications that run on it. In GitOps, a Git repository contains declarative descriptions of all desired according to the four following principles: Kubernetes is just one example of many modern, cloud-native tools that are declarative and can be treated as code. The system’s entire infrastructure must

Performance: The Facts How GitOps Boosts Business Performance: The Facts 2 INTRODUCTION As cloud-native applications have become more prevalent, the concept of DevOps has changed the way software is developed native technologies that together make the promise of DevOps easier to realize. Created for a cloud-native world, GitOps makes developers more productive while improving application stability, security it clear that when DevOps is implemented properly, both speed of development and stability of applications are improved. This in turn correlates directly with organizational success: profitability and

around the world and is divided into user space (where most applications run) and kernel space (which provides an interface for applications to interact with the underlying hardware). The kernel has visibility highly performant, but needs to provide a stable interface to applications, so it lacks the flexibility of user space programming. Applications User space Kernel System calls Files Networking Process contributed upstream, they also need constant adjustments to adapt to the evolution of the kernel.
