a) A globally distributed, multi-model database service
b) A service for managing virtual machines
c) A service for creating web apps
d) A data storage service for unstructured data
Answer:
a) A globally distributed, multi-model database service
Explanation:
Azure Cosmos DB is a globally distributed, multi-model database service that provides low latency and high availability for modern applications. It supports various data models, such as key-value, document, graph, and column-family, and it allows for automatic scaling and replication across multiple regions.
With Cosmos DB, developers can easily build globally distributed applications without worrying about data consistency or availability issues. It provides multiple consistency models and guarantees millisecond response times.
Cosmos DB is often used in scenarios such as gaming, IoT applications, and real-time web apps where global data distribution is essential.
