I am preparing a layout for designing a cloud platform (IoT application) for a battery management system. The voltage, current and temperature of the battery would be recorded. The data from the BMS would be sent via hardware such as Raspberry Pi, etc. and Cloud could be any (Google Cloud IoT / Microsoft Azure / Amazon). Since everything is on design phase, What could be the possible challenges to this application? Are the data fetched on time or time delay estimated is to be done??
