Explanation

Azure Cosmos DB is a globally distributed, multi-model database service that can be used to store and query large amounts of data with low latency. Cosmos DB supports various data models, including NoSQL, and is designed for high throughput and low latency. It can be used to store the data from the IoT devices and can handle the high write and read throughput required for the solution. Azure Time Series Insights is a time-series data platform that is designed for analyzing time- stamped data. It can be used to visualize the data from the IoT devices in near real-time, providing a way to monitor and analyze the device data in real-time. It also has built-in support for IoT data, making it a good choice for this scenario.
