Overview of this book

Node-RED is a free and open source flow-based programming tool used to handle IoT data that allows programmers of any level to interconnect physical I/O, cloud-based systems, databases, and APIs to build web applications without code. Practical Node-RED Programming is a comprehensive introduction for anyone looking to get up to speed with the Node-RED ecosystem in no time. Complete with hands-on tutorials, projects, and self-assessment questions, this easy-to-follow guide will help you to become well versed in the foundations of Node-RED. You’ll learn how to use Node-RED to handle IoT data and build web applications without having to write complex code. Once you’ve covered the basics, you’ll explore various visual programming techniques and find out how to make sample flows as you cover web development, IoT development, and cloud service connections, and finally build useful real-world applications. By the end of this book, you’ll have learned how to use Node-RED to develop a real-world application from scratch, which can then be implemented in your business.

Chapter 6: Implementing Node-RED in the Cloud

In this chapter, we will learn how to utilize Node-RED, which can be used standalone on a cloud platform (mainly Platform as a Service). Platform as a Service (PaaS) provides an instance that acts as the execution environment for an application, and the application developers only focus on executing the application created by themselves without using their power to build the environment. Node-RED is actually a Node.js application, so you can run it wherever you have a runtime environment for Node.js.

There are various major mega clouds such as Azure, AWS, and GCP, but Node-RED is prepared as a Starter App (a web application that can be launched on IBM Cloud is called a Starter App) by default in IBM Cloud, so we will use it in this chapter.

In this chapter, we'll cover the following topics:

  • Running Node-RED on the cloud
  • What is the specific situation for using Node-RED in the cloud?
  • IoT case study spot on the...
