Effective DevOps with AWS - Second Edition

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.

Chapter 7. Running Containers in AWS

InChapter 6, Scaling Your Infrastructure, our architecture changed quite a bit. We explored different ways to scale our applications in AWS, but one of the major technologies that we left out was containers. Containers are at the heart of the software development life cycle (SDLC) of many major technology companies.

So far, we have used our personal computers to develop our applications. This works well for simple projects, such as our Hello World application. However, when it comes to more complex projects with many dependencies, it's a different story. Have you ever heard of situations in which a certain feature works on a developer's laptop but does not work for the rest of the organization-or-even worse, does not work in production?A lot of these issues stem from the differences between environments. When we build our staging and production environments, we rely on CloudFormation, Terraform, and Ansible, to keep those environments consistent. Unfortunately...
