DevOps for Web Development

Overview of this book

The DevOps culture is growing at a massive rate, as many organizations are adopting it. However, implementing it for web applications is one of the biggest challenges experienced by many developers and admins, which this book will help you overcome using various tools, such as Chef, Docker, and Jenkins. On the basis of the functionality of these tools, the book is divided into three parts. The first part shows you how to use Jenkins 2.0 for Continuous Integration of a sample JEE application. The second part explains the Chef configuration management tool, and provides an overview of Docker containers, resource provisioning in cloud environments using Chef, and Configuration Management in a cloud environment. The third part explores Continuous Delivery and Continuous Deployment in AWS, Microsoft Azure, and Docker, all using Jenkins 2.0. This book combines the skills of both web application deployment and system configuration as each chapter contains one or more practical hands-on projects. You will be exposed to real-world project scenarios that are progressively presented from easy to complex solutions. We will teach you concepts such as hosting web applications, configuring a runtime environment, monitoring and hosting on various cloud platforms, and managing them. This book will show you how to essentially host and manage web applications along with Continuous Integration, Cloud Computing, Configuration Management, Continuous Monitoring, Continuous Delivery, and Deployment.

Introduction


We all know what Continuous Integration (CI) is, right? It is the first step in our journey.

 

"The journey of a thousand miles begins with one step."

 
 -- Lao Tzu, the father of Taoism

In simple words, CI is a software engineering practice where each check-in made by a developer is verified by either of the following:

  • Pull mechanism: Executing an automated build at a scheduled time

  • Push mechanism: Executing an automated build when changes are saved in the repository

This step is followed by executing a unit test against the latest changes available in the source code repository.

Jenkins doesn't need the introduction; it is an open source and one the most popular CI tools available in the market. It helps in automating the repetitive task of CI. Jenkins makes the process effective and transparent.

 

"We are what we repeatedly do. Excellence, then, is not an act, but a habit."

 
 -- Aristotle

The next question you may ask is what makes Jenkins so popular. I already gave you one reason...
