As regards the operating systems you will need, there are no real prerequisites. Most of the tools we will use are cross-platform and compatible with Windows, Linux, and macOS. Their installations will be detailed in their respective chapters.

The cloud provider that serves as an example in this book is Microsoft Azure. If you don't have a subscription, you can create a free account here: https://azure.microsoft.com/en-us/free/.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "To execute the initialization, run the init command."

A block of code is set as follows:

resource "azurerm_resource_group" "rg" {
     name = var.resoure_group_name
    location = var.location
     tags {
         environment = "Terraform Azure"
     }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

resource "azurerm_resource_group" "rg" {
    name = "bookRg"
    location = "West Europe"
    tags {
        environment = "Terraform Azure"
    }
}

Any command-line input or output is written as follows:

git push origin master

Bold: Indicates a new term, an important word, or words that you see on screen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Choose the integration of Git in Windows Explorer by marking the Windows Explorer integration checkbox."
