Might not be beginner friendly if you are migrating a complex data estate.

What recommendations would you give to someone considering this product?

Ask questions as to why you need a NoSQL database in the cloud. Look at the pros and cons of your product in the long run.

What differentiates Azure Cosmos DB from other similar products?

Azure Cosmos DB differentiates itself from other NoSQL and globally distributed database platforms through its combination of global distribution, low latency guarantees, flexible APIs, and strong SLAs. Unlike many similar products, Cosmos DB allows you to replicate your data across any number of Azure regions with single-digit millisecond read/write latency and automated failover. It provides five consistency models, giving developers fine-grained control between performance and data accuracy, rather than the rigid strong/eventual choices offered by most competitors.

What is your favorite aspect of this product?

My favorite aspect of Azure Cosmos DB is its global distribution combined with predictable low-latency performance. The ability to replicate data across multiple Azure regions with just a few clicks—and still maintain single-digit millisecond response times—makes it incredibly powerful for building truly global applications. What stands out even more is the flexible consistency models. Instead of being forced to choose between just strong or eventual consistency, Cosmos DB offers five well-defined levels. This gives you fine-grained control to balance performance, cost, and accuracy based on your application’s needs.

What do you dislike most about this product?

The aspect I dislike most about Azure Cosmos DB is the complexity around cost management and partitioning. While the platform delivers excellent performance, the pricing model based on Request Units (RU/s) can be difficult to estimate accurately, especially for new workloads. Small design mistakes—like an inefficient partition key or uneven data distribution—can quickly lead to higher-than-expected costs. Another challenge is the limited visibility into partition-level insights. Although metrics are available, identifying hot partitions or workloads that consume disproportionate RUs often requires deeper diagnostics and external tools.

What recommendations would you give to someone considering this product?

My main recommendation for anyone considering Azure Cosmos DB is to spend time upfront on data modeling and choosing the right partition key. This single decision has the biggest impact on performance, scalability, and cost. A well-designed partition strategy ensures even data distribution, predictable RU consumption, and smooth scaling as workloads grow. I would also suggest beginning with serverless or autoscale if you’re unsure about throughput requirements. This helps avoid over-provisioning and provides a clearer view of real workload patterns before committing to fixed RU/s. Another important one is to understand consistency models
