system. THE GITOPS GUIDE TO BUILDING & MANAGING INTERNAL PLATFORMS 3 weave.works ▼ Self-service developer experience (DX) In the past, the only way a developer could get access to servers, data team delivers self-service APIs to developers. This team builds and maintains the platform that is consumed by development teams. The platform they build is a collection of self-service APIs, tools, services are internal customers of the platform team. In order to properly fulfill its role as an internal service provider, the platform team must take a strategic approach to resource management. “The challenge

A more refined way to manage configurations and declare the state of everything in a given Kubernetes cluster called GitOps is something that Christian embraced wholeheartedly

applications running in Kubernetes. Freedom of choice Because there is no single tool that can do everything required in your pipeline, GitOps gives you the freedom to choose the best tools for the different control system, and serving as your canonical source of truth, you have a single place from which everything is derived and driven. This trivializes rollbacks; where you can use a `Git revert` to go back developers are already living in Git, incorporating GitOps into your organization is simple. Having everything in one place means that your operations team can also use the same workflow to make infrastructure

container orchestration capabilities like: • Automated rollouts and rollbacks of deployments • Service discovery and load balancing capabilities − As Kubernetes gives its own IP address to Pods and translates into a faster turnaround for new features and functionality for the customer. SELF-SERVICE With the existing CI/CD approach, the development team remains dependent on the operations team empowers teams to become more efficient and strategic. It enables development teams to be more self-service in nature as they would be less dependent on platform and operations teams to deploy and handle

GitOps? An developer-centric approach to Continuous Delivery and infrastructure operation Treat everything as code Git is the single source of truth Operations through Git workflows 5 GitOps maintenance Pipeline as a service with no Ops overhead Plugins shared across CI engine Pipelines fully isolated from each other Plugin dependencies with undefined update cycles Everything lifecycled as container repository content to remote OpenShift and Kubernetes clusters A cluster-scope Argo CD pulls cluster service configurations into into the OpenShift cluster OPENSHIFT GITOPS 30 GitOps Application Manager

features, failure rate of code changes, frequency of deployment and the time it takes to restore service following an outage. In this white paper, we’ll explain the best way to achieve the results achieved performing well reported an average lead time of between one and six months. 3. Time to restore service This is defined by DORA as the average time from the detection of a user-impacting incident to one week Between one week and one month Between one month and six months Time to restore service Less than one hour Less than one day Less than one day Between one week and one month Change

never seeing it again, they would prefer to have small teams of developers work together to handle everything themselves—from building and testing to deploying. The move to DevOps requires technical and guarantees to track and manage changes across the entire cluster. P.7 Run Weaveworks on Amazon Web Service (AWS) Weavework’s invented and honed GitOps to accelerate and automate the installation of production-grade production-grade Kubernetes. The Weave Kubernetes Platform (WKP) works with Amazon Elastic Kubernetes Service (Amazon EKS). WKP includes enterprise-grade features that extend the richness of GitOps using a
