In this chapter, we will walk through an example to demonstrate serverless platforms working together on a Docker cluster, and we will demonstrate several serverless/FaaS use cases.
We will discuss a mobile payment scenario and implement it using functions but, unusually at this level of infrastructure, we will connect all three FaaS platforms together. The main ideas demonstrated by the content of this chapter are the concept of using functions as a Glue, using functions to wrap the legacy web-based application, and using functions as a data stream processing program.
In the next section, we will start with the settings and scenario used by this chapter.
The topics covered in this chapter are:
- A mobile payment scenario
- A Parse platform as a backend
- Preparing a WebHook in Fn
- An event state machine with a blockchain
- Wrapping a legacy with a function...
