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: "The document comprises of two primary sections: a Parameters section, which contains a list of actions to be performed by the document, followed by a mainSteps section that specifies the action, which in this case is the aws:configurePackage to be performed by the document. In this case, the document when invoked will ask the user to select either apache2, mysql-server, or php from the dropdown list followed by an optional version number of the software you select."

A block of code is set as follows:

{ 
    "Effect": "Allow", 
    "Action": [ 
      "ec2messages:AcknowledgeMessage", 
      "ec2messages:DeleteMessage", 
      "ec2messages:FailMessage", 
      "ec2messages:GetEndpoint", 
      "ec2messages:GetMessages", 
      "ec2messages:SendReply" 
    ], 
    "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:

{ 
    "Effect": "Allow", 
    "Action": [ 
      "ec2messages:AcknowledgeMessage", 
      "ec2messages:DeleteMessage", 
      "ec2messages:FailMessage", 
      "ec2messages:GetEndpoint", 
      "ec2messages:GetMessages", 
      "ec2messages:SendReply" 
    ], 
    "Resource": "*" 
},

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

# wget https://s3.amazonaws.com/ec2-downloads-windows/SSMAgent/latest/debian_amd64/amazon-ssm-agent.deb

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 the Create Role wizard, select the EC2 option from the AWS service role type, as shown in the following screenshot. Next, select the EC2 option as the use case for this activity and click on Next: Permissions button to continue."
