Applying DevOps

Hands-On Training: applying DevOps immediately

(Software Architects, Software Developers, Software Tester, DevOps Engineers)

Relevance of DevOps and Technologies

DevOps is revolutionizing the way software is developed, deployed, and operated by shortening release cycles and consistently ensuring quality. The essence of DevOps is automation. This not only boosts efficiency but also systematically reduces error sources, creating shorter feedback cycles that enable true agility. DevSecOps takes this further by continuously integrating automated security checks into the process. Key technologies central to this include containers, for a consistent execution environment and thus platform independence. Kubernetes enables container orchestration across multiple hosts and even clusters, thereby providing fail-safety and scalability. With GitHub Actions as an automation platform, a dynamic CI/CD solution can be realized that natively corresponds to the GitOps approach. Professional monitoring and observability solutions offer continuous monitoring and enable real-time understanding of system behavior to continuously improve system reliability.

Why This Course Stands Out

In this course, we'll jointly work through 10 continuous development stages to build a real-world project. You'll directly apply the introduced technologies, gaining valuable experience in integration, troubleshooting, and implementing security best practices from the start. This approach will equip you with a holistic understanding of DevOps and how tools, concepts, and technologies work together, allowing you to put your knowledge to immediate, productive use.

Course Structure: Hands-On Project with Continuous Evolution

We'll start with an existing web application of appropriate size – already versioned in Git. It consists of a frontend, backend services with individual databases, and a message broker. We'll refresh containerization basics using Docker/Compose and then dive into Kubernetes, the foundation for scalable and reliable container management across multiple hosts and clusters.

Next, we'll use GitHub Actions for automated CI/CD, simplifying the application deployment process. We'll focus on proven secret management methods and implement centralized logging and monitoring using the "EFK stack" plus Prometheus and Grafana.

As we progress, we'll deploy the Istio service mesh for advanced network control, security, and observability. Finally, we'll introduce Helm and Argo CD, tools that streamline and scale the DevOps stack for complex applications.
