Overview of this book

The DevOps movement has transformed the way modern tech companies work. Amazon Web Services (AWS), which has been at the forefront of the cloud computing revolution, has also been a key contributor to the DevOps movement, creating a huge range of managed services that help you implement DevOps principles. Effective DevOps with AWS, Second Edition will help you to understand how the most successful tech start-ups launch and scale their services on AWS, and will teach you how you can do the same. This book explains how to treat infrastructure as code, meaning you can bring resources online and offline as easily as you control your software. You will also build a continuous integration and continuous deployment pipeline to keep your app up to date. Once you have gotten to grips will all this, we'll move on to how to scale your applications to offer maximum performance to users even when traffic spikes, by using the latest technologies, such as containers. In addition to this, you'll get insights into monitoring and alerting, so you can make sure your users have the best experience when using your service. In the concluding chapters, we'll cover inbuilt AWS tools such as CodeDeploy and CloudFormation, which are used by many AWS administrators to perform DevOps. By the end of this book, you'll have learned how to ensure the security of your platform and data, using the latest and most prominent AWS tools.

The purpose of this chapter is to introduce and lead the reader to transform what is commonly called monolithicapplication into a dynamic and scalable application.

What is a monolithic application?

When people talk about scaling, they often use the term monolithic application. But what is this, exactly? Usually, this refers to a software or an infrastructure where everything(including the presentationpart, backend, and data part) is combined in a single block, called a monolith. In our case, we are focusing on the infrastructure. To explain the concept of a monolithic application, we are going to build an example application with the following components as shown in the figure below:

  • A MySQL database where there is only one table with a single numeric field
  • A backend frontend Java/Tomcat listening on the default 8080 port component that reads the database, shows the value, and increments the numeric value
  • An Apache 2.2 web server listening on default port 80 that communicates...
