Load testing helps Microsoft process millions of daily IoT sensor readings in its facilities, ensuring that data about room occupancy, temperatures, and other factors is available in near real-time. This timely information is crucial for tasks like booking meeting rooms, which can significantly enhance employee productivity and overall experience.

Microsoft employs a Digital Integration Platform powered by Azure Digital Twins to manage IoT sensor data across over 300 buildings globally. This platform allows for simultaneous processing of data from various sensors, ensuring system stability and reliability while handling an expected growth from two million to around 30 million readings per day.

The Microsoft team gathers baseline load data and conducts various tests, including peak load and endurance runs, to evaluate system performance under stress. They utilize tools like Apache JMeter and Azure Kubernetes Service to simulate real-life scenarios, ensuring the platform can handle current and future demands effectively.
