Use cases

Now that we have a basic understanding of Cloud Functions, let's have a look at numerous use cases. Remember that, in each of these use cases, you can still use other compute options. However, it is a matter of delivering the solution quickly, taking advantage of in-built autoscaling, and paying only for what we have used.

Application backends

Instead of using virtual machines for backend computing, you can simply use functions. Let's have a look at some example backends:

• IoT backends: In the IoT world, there's a large number of devices that send data to the backend. Cloud Functions allow you to process this data and auto-scale it when needed. This happens without any human intervention.
• Mobile backends: Cloud Functions can process data that's delivered by your mobile applications. It can interact with all the GCP services to make use of big data, machine learning capabilities, and so on. There is no need to use any virtual machines and...
