Agile cannot solve all of the DoD’s IT acquisition challenges, but offers a set of principles that can help reduce cycle times and risks to deliver IT in a complex environment. “The US joint Agile within the unique and complex DoD acquisition environment. This guide seeks to adapt proven principles of Agile development specifically to the DoD context. More and more federal acquisition programs exploring a more flexible approach than the traditional defense acquisition framework to apply Agile principles effectively.

implementing a successful GitOps strategy. In this ebook you will learn: • a refresher on the the core principles of GitOps, • how your deployment strategy affects your GitOps plan, and • why observability contributes to the automation of infrastructure. This includes version control, collaboration, compliance, and CI/CD. GitOps is a specific implementation of DevOps that uses Git as the single source respective companies. As a base for exploring and planning your GitOps strategy, review the OpenGitOps Principles, published by the GitOps Working Group: The desired state of a GitOps managed system must be:

automated process ensures the production environment matches the described state. P.4 Weave the principles of GitOps into everyday workflow The foundation of GitOps is based on the declarative nature deployment of committed files. GitOps leverages these attributes according to the four following principles: Kubernetes is just one example of many modern, cloud-native tools that are declarative and managing Kubernetes, teams can increase their overall output 2-3 times and easily meet security and compliance regulations.

Kubernetes. In this Refcard, we will dive into what GitOps means in the Kubernetes world, key principles, and the advantages for cloud-native ecosystems. ABOUT GITOPS FOR KUBERNETES Thanks to the 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 DESCRIPTION Thanks to modern up with the ability to monitor and notify us in this way. COMPLIANCE AND AUDITING CAPABILITIES GitOps helps to follow the compliance and auditing capabilities as needed and regulated in different

network policies and multiple pod networks for traffic isolation. It also provides operators with compliance (via the open source project OpenSCAP) and file integrity (via the open source project AIDE). integrated into the SUSE Rancher platform by late 2022. 3.2.3.2 OpenShift OpenShift offers Compliance Operator, which offers CIS scanning for clusters and nodes out of the box. It has a cron that that runs the scan as often as you want and stores the reports in a PV. It offers additional compliance standards like ACSC, NIST and NERC and offers the possibility to create your own profiles to perform
