So let's look at a few of the best practices involved with the serverless concept.

One function, one task

When we start building functions, we might end up with monolithic functions behind the proxy route and use a switch statement. So, if we have one or a few functions to run our whole app, then we are actually scaling the whole application instead of scaling a specific element of the application. This should be avoided, as scaling would be a problem in this instance, and we also might end up with large and complex functions.
