changed drastically. The “benevolent dictator for life” of any given codebase is being replaced with a team of developers who have to collaborate on a codebase to move it forward. Instead of a single developer weave.works ▼ The platform team has a critical mission: to provide the resources and capabilities that enable application development teams to work effectively. A platform team delivers self-service APIs 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, knowledge, and support

August 2019, and I was making an internal move at Red Hat from the Ansible team to the OpenShift (Red Hat’s Kubernetes product) team. That was when I was introduced to Christian Hernandez. A font of Kubernetes Kubernetes knowledge, Christian would take the lead on building out some of the most complex systems our team could develop. Not only that, he saw a lot of potential for Kubernetes and was looking for ways pandemic. Meeting customers one-by-one via the communication platform du jour wasn’t scalable. Our team started live streaming, and on October 9, 2020, Christian and I hosted our first stream about GitOps

alongside application code in Git. Keeping your entire system in Git means that your development team uses familiar Git-based workflows and pull requests to deploy both application and infrastructure there is a segregated environment, and the state definition lives outside of it. This allows your team to separate what they actually do from how they are going to do it. CONFIGURATION DRIFT DETECTION customer. SELF-SERVICE With the existing CI/CD approach, the development team remains dependent on the operations team to deploy new changes in production. GitOps empowers teams to become more efficient

when there is a divergence. The ultimate goal of GitOps is to speed up development so that your team can make changes and updates safely and securely to complex applications running in Kubernetes. and adopting continuous delivery in your organization easier and will significantly speed up your team’s ability to ship features. eBook 4 The Principles of GitOps The entire system is described declaratively with an integrated feedback control loop speeds up your mean time to deployment. This allows your team to ship 30-100x more changes per day, and increases overall development output 2-3 times. 1. Increased

Reduces the management overhead of the application infrastructure GitOps allows developers or the Ops team to declare their infrastructure as code and version control them via Git. Whenever a new change is repository. 2. Create a pull request. 3. After that, this code can be reviewed and scrutinized by another team member and finally get approved—which triggers the CI/CD pipeline. The pipeline will then inform the unsatisfactory user experience when using the web application. To address this issue, the delivery team wants to increase the resource allocation for the web application. With GitOps, users can define the

technical level, it is important to remember that some of the most useful questions in a software team are the following: ● Does our production environment contain feature X? ● Has feature X cleared environment X but are not in environment Y yet? These questions are very common in a large software team and unless you have a specialized tool on top of your deployment platform, it is very hard to answer previous section (describing GitOps challenges) , some of the most important questions a software team should consider are: ● Does our production environment contain feature X? ● Has feature

development to the DevOps approach. Instead of throwing code over a wall to a separate engineering team and never seeing it again, they would prefer to have small teams of developers work together to handle The monolithic application should be split up into microservices that can each be owned by a single team. Organizational leaders must also create a new culture that celebrates iterating and failing fast application running and ensure that all services are available to their customers 24x7, the engineering team needed a way to deploy new features quickly without compromising on reliability or security. “Leveraging

introduce new features more rapidly without expert knowledge of how Kubernetes works under the hood. New team members get up to speed faster and become productive much sooner. 3. Audit trails for compliance does it help organizations improve their performance, but it makes it easier for them, too. The team at Mettle, a business finance app created by the innovation arm of Britain’s NatWest Bank, used GitOps topology, while the operations team manages platform-wide configurations for policies, security and compliance, ensuring the guardrails are in place. The role of the ops team is therefore to focus on enabling

operate and maintain a GitOps system effectively, you will need a certain level of visibility. Your team will need to detect, diagnose, and resolve issues promptly, ensuring the system’s stability, reliability access controls based on changes in team compositions, responsibilities, or security requirements. Also, you can further enhance your security posture by educating team members about security practices to the core GitOps principles, understand your deployment strategy, and be sure to empower your team with observability to keep your systems resilient and reliable. A GitOps approach complements the
