As the practical examples involve the use of AWS, an AWS account is required.

We also provide a PDF file that has color images of the screenshots/diagrams used in this book. You can download it here: https://www.packtpub.com/sites/default/files/downloads/9781789617313_ColorImages.pdf.

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: "This specifies the action type, either Allow or Deny access."

A block of code is set as follows:

aws s3api put-bucket-tagging --bucket <Bucket> --tagging 'TagSet=[{Key=<key>,Value=<value>}]'

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

<!-- Sample policy -->
<CORSConfiguration>
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>
<MaxAgeSeconds>3000</MaxAgeSeconds>
<AllowedHeader>Authorization</AllowedHeader>
</CORSRule>
</CORSConfiguration>

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

 $ pip install --upgrade --user awscli

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: "Depending on your preference, you can select Current version or Previous versions, or both, as required."
