and system operations teams, which store infrastructure con- figurations. Applications use sensitive data, notably the token or credentials that grant access to a database. For operations, the critical secret information in a Git repository—even a private one behind a firewall—poses a security threat. Git secrets shouldn’t be stored in clear text, even in a private, hosted repository. In this chapter, I Encrypted Secrets Storing encrypted secrets is one of the most popular ways to avoid exposing sensitive data. This solution involves encrypting the secret before uploading it into Git. Later, when the secret

installment in the largest and longest-running project of its kind, pulling together six years of data drawn from over 31,000 technology professionals worldwide. It charts the performance of engineering concepts – speed and stability – might be expected to represent a trade-off. On the contrary, DORA’s data shows businesses that perform well in one tend to perform well in the other. Moreover, businesses via redundancy, which is significantly easier to achieve using GitOps. By storing all configuration data in Git, organizations can consistently deploy identical and complete Kubernetes Platforms to different

Self-service developer experience (DX) In the past, the only way a developer could get access to servers, data, or software was to ask a system administrator. In the modern era, however, developers require on-demand financial services and healthcare, compliance is a high priority. They have specific needs to have data stored only on-premises and ensure a complete audit trail of all actions performed within the system organization looks to deliver an outstanding developer experience—and manage infrastructure from data center to edge—an internal platform is the key enabler. Weaveworks, one of the key organizations

and behavior of a system based on its external outputs, events, and data. It involves gathering and analyzing various types of data including logs, metrics, and traces in order to gain insights into a
