Modeling multi-environment within GitOps tools at any moment. Those continuously compare the current state with the desired state to ensure the system is running like expected. The most popular GitOps tools today are ​Flux organizations are adopting GitOps tools, it is clear that a set of best practices are needed in several areas that are not currently covered by the existing tools. In this guide, we will describe
