teams across the world against four key measures: lead time for new features, failure rate of code changes, frequency of deployment and the time it takes to restore service following an outage. In frequencies, ranging between once a month and once every six months. 2. Lead time for code changes This metric refers to the average time from check-in to production release. Businesses that perform best against not performing well reported an average lead time of between one and six months. 3. Time to restore service This is defined by DORA as the average time from the detection of a user-impacting incident

is now getting the new version. But how do you promote this release to environment Y? Every time somebody declares that adopting GitOps is an easy process, I always ask how promotion between different single repository with 10 branches. This means that you need to open/close 10 pull requests each time you do a release. ● 10 Git repositories. This means that you need to write your own solution that without saying that different people might want a completely different approach for rollbacks. At the time of writing, however, the present GitOps tools have very little support and guidance on how you perform

Specifically, continuous integration (CI) and continuous delivery (CD) tooling. My mindset at the time was, “We can do better.” We had new, declarative tools for infrastructure and a new paradigm to work At the time, someone was trying to do better: A small, scrappy startup called Weaveworks. They’re the ones who coined the term GitOps in 2017. Our futures would be entwined for a significant time after multiple workshops and GitOpsCons and attended regular meetings to help shape GitOps. The entire time, Christian Hernandez established himself as one of the preeminent experts in GitOps. He deftly fielded

declarative, which means deployments are reliable and that any action can be replayed or rolled back at any time. Most of our teams operate their software and systems and are managing their infrastructure including ecosystem of available cloud-native open source projects in order to remain innovative and improve their time to market. However, they needed to implement cloud-native technologies within their highly regulated Principal Engineer, MediaMarktSaturn The path to GitOps adoption Take a phased approach The time it takes for your organization to adopt a GitOps approach greatly depends on where you are in your

Declarative definitions kept in Git allow developers to use familiar workflows, reducing the time it takes to spin up new development, test environments, or deploy new features to a cluster. Teams achieve vs. how it should be achieved, and then the automated system should take care of it ahead of time. The opposite of declarative is an imperative approach where you try to define the sequence of steps run the old version alongside the new version of your application; microservices run at the same time and then switch user traffic from the old to the new version. Once the new version is perfectly

infrastructure changes are available chronologically, enabling users to identify infrastructure changes over time easily. It is also helpful in: Troubleshooting Auditing Rollbacks Changes are automatically applied source-controlled, validated infrastructure reduces configuration errors that can occur during deployments, saving time for Ops teams to diagnose and fix those errors. Besides, source control allows multiple teams to work trails to identify details related to infrastructure changes such as Responsible users Deployment data time Affected resources Etc. The GitOps approach also helps to streamline the management of authentication

When combined - Traceable changes to infrastructure and applications ○ Understand exact state during any prior time period ● Accessible - Changes only require a pull request ● Git as a system of record for the desired
