Which scenario is Cosmos DB NOT particularly suitable for?

Cosmos DB is a globally distributed, multi-model database service designed for high availability, scalability, and performance. It excels in scenarios that involve large volumes of rapidly changing data, such as IoT telemetry, retail transactions, and user data from mobile applications.

When considering the context of static website hosting, this scenario typically relies on serving static files like HTML, CSS, and JavaScript. Using a database like Cosmos DB for this purpose would not be efficient and could introduce unnecessary complexity, as static website hosting often utilizes content delivery networks (CDNs) or simple storage solutions that are optimized for serving static content. This makes Cosmos DB less suitable for such use cases compared to other storage options.

In contrast, scenarios like IoT and telematics, retail and marketing, and mobile applications involve dynamic data that require quick read and write capabilities, as well as the ability to handle large volumes of transactions across distributed locations. Cosmos DB is designed to meet those needs effectively, providing low-latency access and scalability, which are crucial for applications in these domains.
