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: "To create the Redis ElastiCache cluster, first we need to create the security group using the AWS::EC2::SecurityGroup type".

A block of code is set as follows:

AmazonElastiCache amazonElastiCache = AmazonElastiCacheClientBuilder
         .standard()
         .withClientConfiguration(getClientConfiguration())
         .withCredentials(getCredentials())
         .withRegion(getRegions())
         .build();

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

AmazonElastiCache amazonElastiCache = AmazonElastiCacheClientBuilder
         .standard()
         .withClientConfiguration(getClientConfiguration())
         .withCredentials(getCredentials())
         .withRegion(getRegions())
         .build();

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

export PATH=~/.local/bin:$PATH

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: "Choose the Account type of your choice, and provide the required details, and click Create Account and Continue."

Warnings or important notes appear like this.

Tips and tricks appear like this.
