In this chapter, we talked about two important areas where the development effort often goes: input management and identity management. We looked at how to build a resilient and scalable order-ingestion system and how to integrate data into a different data store. Through machine learning, you learned how to predict data (and how to apply it to real-business data). With Azure AD B2C, you finally learned how to outsource the identity management to Identity-as-a-Service (IDaaS).
In the next chapter, we will look at how to enhance mobile application development with Microsoft Azure, Visual Studio, and open source technologies.
