This chapter covered an end-to-end development aspect of a holographic application with IoT scenarios. Overall, the chapter was segregated into three different aspects of development. First, we discussed setting out a backend infrastructure where we simulate sensor data in Azure Event Hub and pass it through Azure Cosmos DB - SQL (DocumentDB) by parsing the raw data through Stream Analytics Jobs. Secondly, we discussed exposing a Web API for the sensor data stored into Azure Cosmos DB - SQL (DocumentDB), and finally, building the holographic application that connects with Azure Services to display live data in our application.

With all that covered, this chapter builds up a solid foundation for building a different connected scenarios application with unlimited possibilities using HoloLens and Microsoft Azure stacks. We will take this learning forward and in the next chapter, we will build another connected holographic solution.
