Learning DevOps: Build Faster, Smarter, and More Reliable Delivery Pipelines
Learning DevOps, 2nd Edition provides a practical and comprehensive introduction to modern DevOps culture, automation, infrastructure as code, continuous integration, continuous delivery, containerization, security, testing, and deployment strategies.
DevOps is more than simply adopting a collection of tools. Successful implementation requires collaboration between development and operations teams, repeatable processes, automation, reliable infrastructure, security integration, and a culture focused on continuous improvement. This book brings these elements together and demonstrates how they can be applied throughout the software delivery lifecycle.
Infrastructure as Code & Cloud Automation
Explore infrastructure as code concepts and learn how tools such as Terraform, Ansible, and Packer can be used to provision, configure, automate, and manage cloud infrastructure. Azure-based examples demonstrate how infrastructure can be created consistently and efficiently while reducing manual configuration.
Development Environments & Source Control
Learn how Vagrant can help create local development environments and explore Git fundamentals, Git commands, and Git flow. These practices provide a foundation for managing source code and creating consistent development workflows.
CI/CD & Automated Software Delivery
Discover how continuous integration and continuous delivery can transform traditional software delivery processes. Build automated pipelines using technologies such as Jenkins, Azure Pipelines, and GitLab CI, helping development teams integrate, test, and deliver software more efficiently.
- Continuous integration workflows
- Continuous delivery pipelines
- Infrastructure deployment automation
- Pipeline-based software delivery
- Automated development processes
Docker & Kubernetes Containerization
Understand how applications can be packaged and deployed using Docker and managed at scale with Kubernetes. The book introduces practical containerization concepts and explains how container platforms fit into modern DevOps environments.
Testing, Quality & DevSecOps
Software delivery must be supported by effective testing and security. Explore API testing with Postman, static code analysis with SonarQube, security and performance testing, and the integration of security practices throughout the DevOps process.
Security-focused technologies and approaches, including Inspec, HashiCorp Vault, and the Azure Secure DevOps Kit, are introduced to demonstrate how security and compliance can become integrated parts of the delivery lifecycle.
