Our client had an IT infrastructure in place which was built around Microsoft technologies. To make their business process more efficient and intelligent, they wanted to revamp this existing PDA based system to a more modern and powerful solution. It wanted to deliver goods with the assistance of IoT-connected mobile devices with Bluetooth printers and Bluetooth temperature sensors mounted in the trucks. Further it also wanted to be able to gather intelligence about customers’ shopping behavioral patterns so that it could provide them with the most relevant goods and services. One of the core challenges in this project was to develop a system that could handle these multiple connected devices which were expected to generate million events every single day. Further the system needed to be scalable so that it can handle large data from thousands of trucks. The system also needed to have provisions for storing and analyzing this huge amount of collected data so that patterns could be identified within it.
