Conventions used

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 X handles. For example; “IoT platforms need to support SigV4, X.509 and custom authentication, while providing fine-grained access control with IoT policies down to the MQTT topic level.”

A block of code is set as follows:

def sum_of_squares_of_odd_numbers(numbers):
    # initialize the sum to zero
    sum = 0
    # loop through the list of numbers
    for number in numbers:
        # check if the number is odd
        if number % 2 == 1:
            # square the number and add it to the sum
            sum += number ** 2
    # return the sum
    return sum

Bold: Indicates a new term, an important word, or words that you see on the screen, for example, in menus or dialog boxes. For example: “Cloud providers such as AWS, Microsoft Azure, and GCP provide many options out of the box that can help you to modernize your system.”
