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.

In each AWS region there is already a default VPC that has been created. If you want to know all of the details of this, I would recommend that you read the Default VPC and Default Subnets documentation at https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/default-vpc.html. However, in short, it is possible to say that everything you put there is potentially exposed to the public network if the security group that you configure allows that. 

Routing and subnet types

In the official documentation at https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Scenarios.html, there are four scenarios described for your VPC configuration, and it will be useful to look into that. It is important to understand that access...
