Modeling multi-environment way you will have full traceability on each production change and can also easily answer critical DevOps metrics such as lead time (the time it takes from a commit to reach production). Observability environment) is often missing or considered secondary knowledge. Additionally, some of ​the classic DevOps metrics​ are very hard to monitor with current GitOps tools. Especially the lead time (the time

your DevOps teams P.2 Git familiar with DevOps and GitOps For over a decade, software companies have been trying to move away from the waterfall approach to application development to the DevOps approach work together to handle everything themselves—from building and testing to deploying. The move to DevOps requires technical and cultural changes at an organizational level. A new set of tools that can Organizational leaders must also create a new culture that celebrates iterating and failing fast. Moving to DevOps is almost always worth the effort. It allows developers to roll out changes and updates very quickly
