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 CI/CD CI/CD is one of the prominent practices in the DevOps movement. This practice delivers applications at frequent intervals to internal or external customers by auto- mating stages of application idea of GitOps is to apply the same workflow to any change that goes into in- frastructure and applications. Changes are proposed by issuing a pull request to the respective Git repository. After reviews

git repository are reflected in the corresponding state of the associated infrastructure and applications through automation.

It provides a fast and secure method for developers to maintain and update complex applications running in Kubernetes. In this Refcard, we will dive into what GitOps means in the Kubernetes open-source system for automating the deployment, scaling, and management of containerized applications. From 2013 to 2014, a revolution in software infrastructure emerged with tools such as Docker

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

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 This process involves re-architecting applications fit into a standardized and vendor-agnostic workflow. It often requires breaking down monolithic applications into microservices, which can be a complex brings about an increase in maintenance tasks. The dynamic and distributed nature of cloud-native applications requires continuous monitoring, updates, and security checks to ensure optimal performance and

building Cloud Native applications that unifies Deployment, Monitoring and Management. It works by using Git as a source of truth for declarative infrastructure and applications. Automated CI/CD pipelines up development so that your team can make changes and updates safely and securely to complex applications running in Kubernetes. Freedom of choice Because there is no single tool that can do everything to the production cluster GitOps separates CI from CD and is a more secure method of deploying applications to Kubernetes. The table below shows how GitOps separates read/write privileges between the

6. Getting started with GitOps 2.0 Introduction GitOps is the practice of deploying applications by using Git Operations only (and not clicking UI buttons). The paradigm already existed in one repositories​”. If you adopt GitOps in a large company with a big number of environments and applications, the number of Git repositories quickly skyrockets. This makes it very hard to keep manager for Kubernetes and is typically seen as the de-facto standard for deploying 3rd party applications in your cluster. It can also be used for your own deployments. Helm works by marrying a set

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 Platform. Once the system is described, it can be versioned in Git. All changes for operations and applications share the same source of truth. Software agents continuously monitor the Git repo and reconcile Kubernetes service used by Fortune 100 companies to run their most sensitive and mission critical applications because of its security, reliability, and scalability. Amazon EKS is deeply integrated with other
