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 Twitter handles. Here is an example: "We have selected the bucket called velocis-manali-trip-112017."

A block of code is set as follows:

{
    "Sid": "AllowCreationOfServiceLinkedRoles",
    "Effect": "Allow",
    "Action": [
        "iam:CreateServiceLinkedRole"
    ],
    "Resource": "*"
}

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

{
    "Sid": "AllowCreationOfServiceLinkedRoles",
    "Effect": "Allow",
    "Action": [
        "iam:CreateServiceLinkedRole"
    ],
    "Resource": "*"
}

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

wget https://d1wk0tztpsntt1.cloudfront.net/linux/latest/install
sudo bash install

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: "On the wizard, select Choose or create role, tag your instance, and install the AWS agent."
