Learning DevOps

By: Mikael Krief

Overview of this book

The implementation of DevOps processes requires the efficient use of various tools, and the choice of these tools is crucial for the sustainability of projects and collaboration between development (Dev) and operations (Ops). This book presents the different patterns and tools that you can use to provision and configure an infrastructure in the cloud. You'll begin by understanding DevOps culture, the application of DevOps in cloud infrastructure, provisioning with Terraform, configuration with Ansible, and image building with Packer. You'll then be taken through source code versioning with Git and the construction of a DevOps CI/CD pipeline using Jenkins, GitLab CI, and Azure Pipelines. This DevOps handbook will also guide you in containerizing and deploying your applications with Docker and Kubernetes. You'll learn how to reduce deployment downtime with blue-green deployment and the feature flags technique, and study DevOps practices for open source projects. Finally, you'll grasp some best practices for reducing the overall application lead time to ensure faster time to market. By the end of this book, you'll have built a solid foundation in DevOps, and developed the skills necessary to enhance a traditional software delivery process using modern software delivery tools and techniques

Summary

In this final chapter, we have seen that the implementation of DevOps culture within projects requires the use of best practices regarding the automation of all manual tasks, the proper choice of tools, a less monolithic project architecture, and the implementation of monitoring.

On a large scale, for the organization of teams and the company as a whole, we have seen that the agile method, as well as multidisciplinary teams, contributes strongly to the implementation of DevOps culture.

To finish this book, my advice to all you readers who are adopting DevOps practices is to implement and monitor them on small projects and to start by using the tools that are most familiar and accessible to you. Then, as soon as your DevOps process is working properly, you can extend it to larger projects.
