The platform serves as a central system for creating IoT applications and ranges from system monitoring of trams to monitoring of photovoltaic systems. In the run-up to this, in addition to an intensive functionality check, a test was carried out on behalf of Wien IT, in which our platform was exposed to high loads. Multiple devices simultaneously sent a large amount of data to the platform, thereby testing it´s stability. After successfully passing these tests, we were officially selected as the IoT platform provider and are currently entering the implementation phase. We are very pleased with this achievement.
