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.

Getting started – monitoring

Let's start with a simple definition of monitoring and then we will gradually move towards cloud monitoring. It is about observing progress of some operation or activities performed and to make sure that end goal or performance objectives are achieved as desired. It expands its area from observing to analysis, from analysis to detection, and from detection to notifications to respective stakeholders for corrective measures.

In general, what kind of monitoring we do in traditional environment? Let's start considering component of Cloud service Model to understand it in a better perspective. In Cloud computing, there are three service models:

  1. Infrastructure as a Service

  2. Platform as a Service

  3. Software as a Service

To get a clue from it, it is extremely important to monitor Infrastructure as well as platform running web application. Let's take a case of AWS EC2 instance that can be used to deploy our sample Spring Application – PetClinic. We need to ensure that Instance...
