With the complexity of the disruptive Big Data technology, it is hard to conclude a single solution as the silver bullet for every problem. At the same time, Big Data fundamentals have not changed since Google's 2004 White Paper publications.

With two decades of hands-on experience, computing fundamentals have never changed in spite of the upcoming technologies like Big Data, Cloud, Internet of Things, digitization, and so on. I feel that easy user interaction makes a product innovative in our industry.

For example, WhatsApp was built with two key fundamentals, namely, real-time messaging and device-embedded authorization. Real-time messaging with traditional sign-on application was quite common in the last decade. The key difference is the mobile-enabled automatic sign-in in WhatsApp. In this era of customer satisfaction, this technology has been well received by the end users for the product's success.
