The main focus of this book is to shed light on serverless and different service provider for serverless. It also teaches how to adopt an automated way to set up DevOps for serverless functions.

You have an understanding of DevOps, continuous integration, and continuous deployment, and should have some knowledge of popular DevOps tools such as Jenkins, ELK (Elasticsearch, Logstash, and Kibana). It is an added advantage if you know about different cloud service providers, such as AWS, Azure, and Google.

Most of my tutorials are build on top of MacBook and Docker containers, so I would recommend using some form of Linux for the tutorials.

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/9781788623445_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: "In the statement, we pass the parameter to the CLI and the stage value is populated in the serverless.yml file."

A block of code is set as follows:

# serverless.yml
service: myService
provider:
  name: aws
  runtime: nodejs6.10
  memorySize: 512 # will be inherited by all functions

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

$ pip install zappa

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: "Click on Users on the left-hand sidebar, then click on the Add User button and add the username adm-serverless."
