In this chapter, we are going to modify an existing service and create an entirely new service. First up, we are going to add support for message queues (MQs); as you will learn, MQs are invaluable for communication in an IoT system. This chapter we will set up the plumbing for a basic insecure message queue. But as we move along, we will add security and more in later chapters. In addition, we will also discuss GraphQL, which, if you’ve only used REST, you are in for a treat. GraphQL helps solve many of the limitations and frustrations that come in a RESTful system.
