To use this book, you will need access to computers, servers, or cloud-provider services where you can provision virtual machine instances. To set up the lab environments, you may also need larger cloud instances that will require you to enable billing.

We assume that you are using an Ubuntu host (18.04, codename Bionic Beaver at the time of writing); the book provides steps for Ubuntu environments.

You will need AWS, GCP, and Azure credentials to perform some of the recipes in this book. 

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to copy/pasting of code.
