Conventions Used

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

Code in text: 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: “You will use the detect_labels API from Amazon Recognition in the code.”

A block of code is set as follows:

{
  "Effect": "Allow",
  "Principal": {
    "CanonicalUser": "b035577b325d98aa1e72ca0000EXAMPLE"
  },
  "Action": "s3:GetObject",
  "Resource": "arn:aws:s3:::abcuser-bucket/*"
}

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

aws iam create-login-profile --user-name Packt --password Ch@ng3mE --password-reset-required

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: “In CloudWatch, each Lambda function will have a log group and, inside that log group, many log streams.”
