Effective DevOps with AWS - Second Edition

By: Yogesh Raheja, Giuseppe Borgese, Nathaniel Felsen

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.

Creating our first web server

Now that we have our environment set up, we are finally ready to launch our first EC2 instance. There are a couple of ways to do that. Since we just installed and configured awscli and we want to see effective ways of managing infrastructures, we will demonstrate how to do this using the CLI.

Launching a virtual server requires having a certain amount of information ahead of time. We will use the aws ec2 run-instances command, but we need to supply it with the following:

  • An AMI ID
  • An instance type
  • A security group
  • An SSH key-pair

Amazon Machine Images (AMIs)

An AMI is a package that contains, among other things, the root file system with the operating system (for example, Linux, UNIX, or Windows) as well as additional software required to start up the system. To find the proper AMI, we will use the aws ec2 describe-images command. By default, the describe-images command will list all available public AMIs, which is way over 3 million by now. To get the best out of...
