Few understand big data from its core computing principles. Among those select knowledge experts is Dejan Milojicic, an IEEE Computer Society Past President and Distinguished Technologist with HP Labs. The IEEE Big Data Podcast interview with Mr. Milojicic dives into the everyday fundamentals—from generation to filtering—and then into the vastness of big data's architecture. Is it a simple look into the future? Today, it's more about information… rather than the data itself. Understanding the difference between data "at rest" and data "in flight" and determining how they're secured is what will have the greatest impact for tomorrow.
