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) we need dedicated tools for all these questions. Ideally, a GitOps solution should have native support for measuring and storing historical data for: ● Business features implemented in each release Codefresh already has strong CD foundations, but they are based on the push-model (deploying Helm packages on a cluster). With the addition of Argo, our customers can now create GitOps pipelines if they

these tools and resources that eliminate obstacles. Developers should not have to file a list of support tickets and wait forever to get what they need. It’s a good idea to have a consistent process in that build features and release code into production. Platform teams, on the other hand, exist to support application development teams and make resources available to them whenever needed. Application The platform they build is a collection of self-service APIs, tools, services, knowledge, and support. Development teams have a high degree of autonomy, but they also rely on the platform team to
