It covers the intersection of development, security, and operations, equipping you with both the technical expertise and soft skills required for this role. Apart from the necessary theory, it provides a large number of examples as well as hands-on labs to familiarize you with practical applications.
The book begins with essential soft skills, introducing you to frameworks like Agile and Lean along with Scrum and Kanban. To better explain the topic and practical applicatins, an example Python project of an executable package is included. Then the book take you into a deepdive, demonstrating the process of gradually improving the project adding the explained topics as new features avoiding unnecessary rework. The book also covers security topics including source code compliance analysis and vulnerabilities scans, system security, data encryption and identity validation using GPG, X.509 certificates and PKI.
The book delves on the most commonly used protocols (HTTP, TLS, LDAP), providing also an overview of service protocols such as SOAP and REST. Along with this it also covers containers (Docker, Podman), with an overview of Kubernetes and Helm, and a hands-on lab for installing Rancher and Deploying Gitea on top of it. Gitea is also exploited to delve into Git. The book ends showing how to operate with Ansible using playbooks, roles and collections. After reading this book you will be able to solve complex challenges, create secure and maintainable solutions, and become a trusted and respected member of any DevSecOps team.
