• Azure Table API: Built to provide low-latency, automatic indexing, global distribution, and other features of Azure Cosmos DB to existing Azure Table storage applications with minimal effort[1].

Turnkey Global Distribution

One of the standout features of Azure Cosmos DB is its turnkey global distribution. This allows you to distribute your data across multiple Azure regions with just a few clicks, keeping your data close to your users to boost application performance. The multihoming APIs ensure that your application always knows where the nearest copy of your data lies, without any configuration changes, even as you add or remove regions[1].

Multi-Master Support

With multi-master support, you can write data to any region associated with your Cosmos DB account, and these updates propagate asynchronously. This enables seamless scaling of both write and read throughput worldwide, with single-digit millisecond write latencies at the 99th percentile and 99.999% write and read availability. The comprehensive and flexible built-in conflict resolution makes it crucial for building globally distributed applications[1].

Data Modeling in Azure Cosmos DB

Data modeling in Azure Cosmos DB is different from traditional relational databases due to its NoSQL nature. Here are some best practices and methods to ensure effective data modeling:

Understanding Access Patterns

• Analyze the categories of queries your application will run.
• Determine the rate of operations (reads compared to writes).
• Plan the process for updating or removing data.

For instance, if your application frequently accesses a customer’s order history, you should design your schema to reduce cross-document queries[3].

Choosing the Right Partition Key

• Select a partition key with high cardinality (a large number of unique values) to ensure even data distribution across partitions.
• This approach helps in better load balancing and performance, as the total number of Request Units (RU/s) is evenly divided across all physical partitions[1][3].

Embedding and Referencing

• Manage data embeddings (storing related data together in a document) and references (storing related data separately and linking them) carefully.
• Focus on understanding your access patterns and plan for future scalability needs to design a schema that supports easy updates and efficient data retrieval as your system scales[3].

Global Access and Local Speed

Azure Cosmos DB replicates your data worldwide, ensuring that users always connect to the nearest data center for lightning-fast access. Here are some key benefits:

Automatic Failover

• If one region experiences issues, other regions automatically step in to keep your application reliable and resilient.
• This ensures predictable performance, no matter how big your data or traffic gets, thanks to the SLAs covering speed, availability, and consistency[3].

Flexible Scaling

• Azure Cosmos DB adapts as your application grows, whether you need more storage or throughput.
• It scales automatically, helping you handle spikes in traffic without overspending or missing a beat[3].

Use Cases and Applications

Azure Cosmos DB is widely used in various sectors due to its robust features and scalability.

Real-Time Gaming

• For real-time gaming applications like GTA V, Azure Cosmos DB delivers lightning-fast performance and global distribution with millisecond latency, making it a game-changer[4].
