Introduction 08 Chapter 1–What is GitOps? Origins in DevOps Kubernetes and containers Cloud-Native DevOps A DevOps Operating Model GitOps Principles Declarative Versioned very positive feedback and later became a recurring show. Eventually, this work led us to the Cloud Native Computing Foundation’s GitOps Working Group (and later the OpenGitOps project). By then, GitOps 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

approach to software delivery. Here are some of the key reasons: Manage deployments from on-premise to cloud to edge Scale infrastructure to meet demands Enable built-in compliance Enforce zero-trust security great example of an organization that needs to support legacy applications and extend them with cloud capabilities and modern practices like GitOps. The platform approach at Deutsche Telekom enables repeatable and reusable. This trait is especially useful when an application needs to be scaled at cloud burst speed. Being in the retail space, MediaMarktSaturn has many days of unusually high traffic

GitOps is a way to do Continuous Delivery. More specifically, it is an operating model for building Cloud Native applications that unifies Deployment, Monitoring and Management. It works by using Git as a The entire system is described declaratively. Kubernetes is just one example of many modern cloud native tools that are “declarative” and that can be treated as code. Declarative means that configuration cluster, make a small update to the application and deploy the change with Weave Cloud. In our product Weave Cloud, the GitOps core machinery is in its CI/CD tooling with the critical piece being continuous

ABOUT GITOPS FOR KUBERNETES Thanks to the DevOps movement, the focus on and responsibilities and tweaks would be taken care of by an automated mechanism. Since Kubernetes and many other cloud-native technologies are almost entirely declarative, infrastructure definitions can be kept alongside

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 positive effect is not limited to the performance of engineering teams. Technology, in particular cloud native technology like Kubernetes and its ecosystem of projects, is now a core competency for organizations practices and operating models for managing cloud native technologies that together make the promise of DevOps easier to realize. Created for a cloud-native world, GitOps makes developers more productive

infrastructure. In this article, we will have a look at GitOps and how to leverage it for delivering cloud-native applications. What is GitOps? GitOps is a set of practices that are aimed at managing the underlying to consider is the Git repository. As GitOps is platform-agnostic, users can utilize any local or cloud-based Git repository such as: GitHub BitBucket Azure Repos GitLab Etc. Then comes the CI/CD pipeline communications between them. There are multiple available operators such as: Kubernetes Operator Terraform Cloud Operator Azure Service Operator Etc. GitOps workflow Now, we’ve got a Git repository and a properly

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 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 CloudWatch, Auto Scaling Groups, AWS Identity and Access Management (IAM), and Amazon Virtual Private Cloud (VPC), providing a seamless experience to monitor, scale, and load-balance applications.
