Identify Key Characteristics Of Azure Cosmos DB

You work as a database architect for MDFT Pro, a well-known training agency that is developing a global online learning platform for Microsoft certification courses. The platform needs to support millions of students worldwide with real-time features like live chat, instant quiz feedback, and collaborative learning tools. Mark, the global platform director, has asked you to evaluate Azure Cosmos DB for this high-performance, globally distributed application.

Claire, the development team lead, needs to understand the key characteristics that make Azure Cosmos DB suitable for their online learning platform, which requires fast data access for student profiles, course progress, real-time messaging, and instant leaderboard updates across multiple continents.

What are the key characteristics of Azure Cosmos DB?

Choose all correct answers from the options below.

Explanations for each answer:

It requires no administration is incorrect. Azure Cosmos DB is a Platform as a Service (PaaS) offering, which means some administration is still required. While Microsoft manages the infrastructure, database administrators still need to configure settings, manage security, optimize performance, and handle data modeling.
It supports multiple geographic regions is correct. Azure Cosmos DB provides turnkey global distribution, allowing you to replicate your data across multiple Azure regions worldwide. This enables low-latency access for users regardless of their geographic location and provides high availability through automatic failover capabilities.
It supports relational data only is incorrect. Azure Cosmos DB is specifically designed as a NoSQL database that handles semi-structured and unstructured data. It doesn't support traditional relational data structures like SQL tables with foreign keys and joins.
It has very low latency for data reads and writes is correct. Azure Cosmos DB is designed for ultra-low latency, guaranteeing single-digit millisecond response times for both reads and writes at the 99th percentile. This makes it ideal for real-time applications that require immediate data access and updates.
It supports a single application programming interface (API) is incorrect. Azure Cosmos DB supports multiple APIs including SQL API, MongoDB API, Cassandra API, Gremlin API, and Table API. This multi-API support is one of its key features, allowing developers to use familiar programming interfaces.
