AnalyticsPBI for Azure: Turning Real-Time Signals into Real-Time Analytics

By Terence Craig

PBI 3 0 archslide 3For the second post on AnalyticsPBI for Azure (first one here), I thought I would give you some insight on what is required for a modern real-time analytics application and talk about the architecture and process that is used to bring data into AnalyticsPBI and create analytics from them. Then we will do a series of posts on retrieving data. This is a fairly technical post so if your eyes start to glaze over, you have been warned.

In a world that is quickly moving towards the Internet of Things, the need for real-time analysis of high velocity and high volume data has never been more pronounced. Real-time analytics (aka streaming analytics) is all about performing analytic calculations on signals extracted from a data stream as they arrive—for example, a stock tick, RFID read, location ping, blood pressure measurement, clickstream data from a game, etc. The one guaranteed component of any signal is time (the time it was measured and/or the time it was delivered).  So any real-time analytics package must make time and time aggregations first class citizens in their architecture. This time-centric approach provides a huge number of opportunities for performance optimizations. It amazes me that people still try to build real-time analytics products without taking advantage of them.

Until AnalyticsPBI, real-time analytics were only available if you built a huge infrastructure yourself (for example, Wal-Mart) or purchased a very expensive solution from a hardware-centric vendor (whose primary focus was serving the needs of the financial services industry). The reason that the current poster children for big data (in terms of marketing spend at least), the Hadoop vendors, are “just” starting their first forays into adding support for streaming data (see CloudEra’s Impala, for example) is that calculating analytics in real-time is very difficult to do. Period.
