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: “The configuration patch is applied to HTTP_FILTER and in particular to the HTTP router filter of the http_connection_manager network filter.”

A block of code is set as follows:

"filterChainMatch": {
                    "destinationPort": 80,
                    "transportProtocol": "raw_buffer"
                },

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

"filterChainMatch": {
                    "destinationPort": 80,
                    "transportProtocol": "raw_buffer"
                },

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

% curl -H "Host:httpbin.org" http://a816bb2638a5e4a8c990ce790b47d429-1565783620.us-east-1.elb.amazonaws.com/get

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Cloud computing is utility-style computing with a business model similar to what is provided by businesses selling utilities such as LPG and electricity to our homes"
