Summary

In this chapter, you learned how to deploy a serverless API backed by an infinitely scalable database and fronted by an infinitely scalable web application. You covered more of the nuts and bolts of connecting serverless code to other services, along with logging and security considerations. Having the serverless code implement the API may feel like an over-complication at the moment (why not call the Cosmos DB directly from the controller of the MVC client application?), but the benefits of it being loosely coupled to the web application while the functions are also loosely coupled to each other will become apparent later.

Now that you've covered the basics of creating a simple architecture, we can add some more interesting features and components in the next chapter.
