Over the last five years, 'The DevOps Handbook' has been the definitive guide for taking the successes laid out in the bestselling The Phoenix Project and applying them in any organization. Now, with this fully updated and expanded edition, it's time to take DevOps out of the IT department and apply it across the full business.
Chapter 1: What is DevOps?
* Defines DevOps as a collaborative approach between development (Dev) and operations (Ops) teams to improve software delivery.
* Example: A software development team working with the operations team to ensure seamless deployment and maintenance of their products.
Chapter 2: The DevOps Toolchain
* Introduces the tools and technologies that support DevOps practices, such as version control, continuous integration, and deployment automation.
* Example: Using Git for version control, Jenkins for continuous integration, and Puppet or Ansible for deployment automation.
Chapter 3: Building a DevOps Culture
* Emphasizes the importance of fostering collaboration, transparency, and accountability within DevOps teams.
* Example: Encouraging open communication, conducting regular team retrospectives, and defining clear responsibilities for each team member.
Chapter 4: Measuring DevOps Success
* Provides metrics and best practices for measuring DevOps effectiveness, such as lead time, deployment frequency, and change failure rate.
* Example: Tracking the time it takes for new features to go from development to production, and identifying areas where the process can be improved.
Chapter 5: Continuous Integration
* Explains the benefits and best practices for continuous integration, including automated builds, unit tests, and code coverage analysis.
* Example: Using a tool like Jenkins to automatically build and run tests on every code change, providing immediate feedback to developers.
Chapter 6: Continuous Deployment
* Describes the principles and techniques of continuous deployment, emphasizing the benefits of automating the deployment process.
* Example: Utilizing tools like Ansible or Kubernetes to define and automate the deployment of software updates with minimal downtime.
Chapter 7: Infrastructure as Code
* Introduces the concept of infrastructure as code, where infrastructure is defined and managed using code instead of manual configuration.
* Example: Using a tool like Terraform to define and manage cloud resources, such as servers, networks, and databases.
Chapter 8: Security in DevOps
* Discusses the importance of incorporating security considerations into DevOps practices, including secure coding, vulnerability management, and access control.
* Example: Implementing a code review process to ensure security vulnerabilities are identified and addressed before deployment.
Chapter 9: Scaling DevOps
* Provides guidance on scaling DevOps practices to large organizations, including managing dependencies, automating testing, and developing a robust DevOps infrastructure.
* Example: Utilizing a service-oriented architecture (SOA) to modularize and reuse components, reducing the complexity and effort required for large-scale DevOps adoption.
