AI Assistant (beta) to help accelerate your learning

The objectives of the first section are to present the DevOps culture and to provide all of the keys for the best Infrastructure as Code practices. This section explains the DevOps application on cloud infrastructure, showing provisioning using Terraform and configuration with Ansible. Then, we improve this by templating this infrastructure with Packer.

We will have the following chapters in this section:

Chapter 1, DevOps Culture and Practices
Chapter 2, Provisioning Cloud Infrastructure with Terraform
Chapter 3, Using Ansible for Configuring IaaS Infrastructure
Chapter 4, Optimizing Infrastructure Deployment with Packer

Key benefits

Learn to utilize business resources effectively to increase productivity and collaboration

Leverage the ultimate open source DevOps tools to achieve continuous integration and continuous delivery (CI/CD)

Ensure faster time-to-market by reducing overall lead time and deployment downtime

Description

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
