altering previous versions (except if the user requests a change explicitly, an extreme and rare event). So you can revert back to a previous version while preserving an audit of all the changes that from the source. This principle is where GitOps starts to differentiate itself from a traditional event-driv- en process (more on that in the next section). Although triggering changes and updates via a reconciliation loop. This design leads to the final principle. Continuously Reconciled The fourth and final principle is another way that GitOps differentiates itself from event-based workflows:

is detected between the two, an alert can be sent, effectively creating a feedback and control loop for managing your cluster. PRINCIPLES OF GITOPS GitOps is based on several core tenets: DECLARATIVE Disaster recovery (DR) is a practice that every organization must have in place to recover from an event that negatively affects business operations. The goal of DR methods is to enable the organization go as planned can be easily rolled back to a previously stable state. With a feedback control loop, you can effectively answer the following questions: • How do I know if my deployment will succeed

reduced significantly, thanks to continuous deployment automation and an integrated feedback control loop. The results are transformative: teams can ship 30-100 times more changes per day, increasing overall error-prone and more reliable. By drastically reducing the time taken to restore service in the event of a problem, GitOps promises much-improved availability for organizations of all kinds. How GitOps

agents act as the feedback and control loop for your operations. 1 3 2 4 eBook 5 Continuous deployment automation with an integrated feedback control loop speeds up your mean time to deployment being continuous deployment (CD) that supports Git-cluster synchronization. This provides a feedback loop that gives you control over your Kubernetes cluster. Here is a typical developer workflow for creating

the desired state of the system is versioned and stored in a Git repository, and a reconciliation loop continuously monitors and enforces that desired state. GitOps takes DevOps practices and puts them
