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

Evolving project management

We have previously discussed some good DevOps practices to apply to projects, but all this can only be implemented and realized with a change in the way that projects are managed and teams are organized.

Here are some good practices that can facilitate the implementation of DevOps culture in project management within companies.

First of all, it should be remembered that DevOps culture only makes sense with the implementation of development and delivery practices that will allow applications to be delivered in short deployment cycles. Therefore, in order to be applicable, projects must also be managed with short cycles. To achieve this, one of the most suitable project management methods to apply DevOps culture and has proven its worth in recent years is the agile method, which uses sprints (short cycles of 2 to 3 weeks) with incremental, iterative deployments...
