BUILDING & MANAGING INTERNAL PLATFORMS Internal platforms are a great way to enable an outstanding developer experience. GitOps is the best way to enable this platform approach. These two sentences are a a concise summary of the key ideas in this paper. In the last few years, the role of the developer has changed drastically. The “benevolent dictator for life” of any given codebase is being replaced forward. Instead of a single developer who owns the codebase making all the decisions, a group of developers works together to make a product. In this situation, developer experience is of utmost importance

increased, and the focus has shifted rightly so to improving the developer experience. In the last few years, the number of tools and systems needed to manage version control, configuration management the developer as they now must oversee more and more components of the application. Ideally, the developer focuses mainly on delivering business value via code. Thus, to improve developer experience infrastructure and application configuration changes. In an ideal world, this approach allows the developer to focus on working and pushing code to Git, and then, further deployment and tweaks would be

as processes improve. “To become Agile, it is not sufficient to just install a handful of new tools, apply some new methods, and rename your milestones to ‘iteration exit.’ Agile will challenge the security risks. Industry has relevant domain experience and Agile development expertise. Developer Expertise Agile development expertise is unavailable or lacks domain experience. Program development and operational testing is conducted serially following development. Limited resources and tools available to conduct parallel development testing. Leadership actively supports Agile development

“you build it, you own it” development process requires tools that developers know and understand. GitOps is our name for how we use developer tooling to drive operations. GitOps is a way to do Continuous to your infrastructure when commits are pushed and approved in Git. It also makes use of diff tools to compare the actual production state with what’s under source control and alerts you when there pipeline, GitOps gives you the freedom to choose the best tools for the different parts of your CICD pipeline. You can select a set of tools from the open source ecosystem or from closed source or depending
