kept 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 in Git allow developers to use familiar workflows, reducing the time it takes to spin up new development, test environments, or deploy new features to a cluster. Teams can ship more changes per day

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 building DX teams to work with platform teams to improve overall organisational productivity and development velocity.” James Governor, — Source Redmonk.com Executive summary Adopting the platform approach they would go about building and maintaining the platform. Further, how they would build a new development culture around the platform that makes software delivery seamless. In this paper, we look at

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

standardizes the deployment and management of complex systems, improves collaboration between development and operations teams, and increases the reliability and reproducibility of deployments. GitOps them to infrastructure automation. Whereas DevOps is the practice of automating the software development lifecycle, GitOps contributes to the automation of infrastructure. This includes version control allowing for rapid, repeatable, and error-free provisioning of infrastructure. Popular tooling to support IaC includes Terraform, Pulumi, Ansible, Salt, and Puppet. These tools provide the necessary capabilities

This built-in observability allows for fast iteration and experimentation, and allows development teams to make crucial decisions before they deploy new features. Features or other updates like

GitOps is only part of your whole development strategy and you should make sure that all other processes and workflows are ready to work with approach for rollbacks. At the time of writing, however, the present GitOps tools have very little support and guidance on how you perform a rollback in a standard way. Observability for GitOps (and Git)

GitOps is our name for how we use alerts you 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 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

way we develop and manage applications, resulting in faster, more consistent, more collaborative development cycles. It has evolved further by incorporating microservices-based architectures and even databases management solutions such as Terraform. The goal of GitOps is to simplify and streamline the development process. This leads to building reproducible infrastructure with proper state management, which 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

away from the waterfall approach to application 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 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 quickly in response to users’ feedback without taking down the whole application and improves development metrics by orders of magnitude in some cases. However, developers using the DevOps approach can
