Key insights

  • Azure Cosmos DB: A fully managed, globally distributed database service from Microsoft that supports NoSQL, relational, and vector workloads.
    It delivers low latency, high availability, and elastic scale for cloud-native apps.
  • Global distribution: Replicate data across regions with multi-region writes and SLA-backed availability.
    This design gives applications single-digit millisecond responses for users worldwide.
  • NoSQL and multi-model: Store schemaless JSON documents and use multiple APIs including PostgreSQL, MongoDB, and Cassandra, plus vector support for AI workloads.
    Query data with SQL-like syntax or the API that matches your app.
  • Request Units (RU/s): The currency for throughput and performance in Cosmos DB that affects cost and latency.
    Choose provisioned, serverless, or autoscale modes to match workload needs.
  • Partition key: A required design choice that drives scalability and query performance.
    Pick a key that balances data and request load across containers and partitions.
  • SDK & CRUD: Use CosmosClient SDKs (for example C#/.NET) to create accounts, databases, containers, and perform CRUD operations and queries.
    These practical skills are important for developers and AZ-204 exam preparation.
