I've been hearing a lot about IoT architecture recently, and Shaspa's story really illustrates how Informix fits in. Briefly, a 4-tier IoT architecture has these components:
2. Gateway devices that collect sensor data. For example, one gateway device in each smart house. Informix is here!
3. Cloud or other centralized storage for data from gateways. Informix is here!
4. Business intelligence software
Shaspa implemented a "smart building" solution with Informix embedded in the gateway device that collects sensor data in each building. They also use Informix to store the data from all the buildings. Read about it here.
