A font of Kubernetes knowledge, Christian would take the lead on building out some of the most complex systems our team could develop. Not only that, he saw a lot of potential for Kubernetes and was 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

cluster and auto-commits (or reverts) to the git repo in order to keep the consistency. This is very complex to accomplish and not all teams want to let their deployment solution have write access to their that you have to accept if you wish to use GitOps with Helm charts making the process much more complex than needed. Continuous Deployment and GitOps do not mix together GitOps is great as a Continuous release should be so easy to perform/monitor/rollback that any team member can handle a deployment event and still have access to all critical information such as which Git commit was deployed and what

business gets it right. In a cloud-based world, software development, delivery and maintenance is a complex process. DevOps improves success enormously, but there remains room for failure. GitOps is, in 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

Git at the center. It provides a fast and secure method for developers to maintain and update complex applications running in Kubernetes. In this Refcard, we will dive into what GitOps means in 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

as the single source of truth. It simplifies and standardizes the deployment and management of complex systems, improves collaboration between development and operations teams, and increases the reliability workflow. It often requires breaking down monolithic applications into microservices, which can be a complex and resource-intensive task - but one that will pay off by providing flexibility in the future. changes from the Git repository but lacks the automation benefits of pull-based deployments. Complex architectures with a mixture of Kubernetes and non-Kubernetes workloads can leverage a combination

GUIDE TO BUILDING & MANAGING INTERNAL PLATFORMS 6 ▼ ▼ As the infrastructure stack becomes more complex, what organizations need is a consistent way to build and deliver applications from on-prem to edge configuration drift Drift of any sort plagues operations teams. Especially as the stack becomes more complex, drift leads to incompatibility between different parts of the stack. GitOps counters this challenge practices the norm without any added effort. Leverage Flagger and a service mesh tool to execute complex progressive delivery patterns like canary releasing and blue-green deployments.initial workshop

It automates complex error prone tasks like having to manually update YAML manifests. With the operator pattern, an
