reduce the incidence of failures, safety nets must be introduced to catch them before problematic code makes it into production. GitOps introduces key safety nets. With the entire state of a running application deployments can be rolled back quickly and easily. As well as reducing failure rate, these two safety nets help increase deployment frequency, the first of DORA’s SDO measures. Time to restore service is

Although triggering changes and updates via webhooks or other events is a valid way to automate reconciliation whenever there is a divergence. I explain where GitOps fits into CI/CD in the next section. GitOps and CI/CD CI/CD is one of the prominent practices in the DevOps movement. This practice cornerstone of DevOps practitioners? I’ll try to answer that question in this section. Traditional CI/CD Workflows In a previous section, we introduced traditional CI/CD as being event-driven. This should be

In this section, we will talk about the solution software delivery and not just those who handle source code. As we explained in the previous section (describing GitOps challenges) , some of the most important questions a software team should consider ways, such as introducing an automation mechanism for Pull Requests (more on this in the next section) or even creating a higher-level abstraction layer for specifying different environments.
