Executive SummaryUpdated on Nov 2, 2025

Couchbase Enterprise and Microsoft Azure Cosmos DB compete in the NoSQL database category. Based on various comparisons, Cosmos DB seems to have an edge due to its seamless cloud integration and global accessibility.

Features: Couchbase Enterprise highlights superior horizontal scalability, ease in application and data merging, and robust documentation. It offers Sync Gateway for mobile support and low latency multi-database paradigms. Cosmos DB provides multi-modal database capabilities, globally distributed access, and flexible scaling. Its ecosystem integration and adaptability across APIs like MongoDB and Gremlin are significant advantages.

Room for Improvement: Couchbase Enterprise could enhance failover processes, integration documentation, and cluster management. Some users point to challenges with certain upgrades and replication reliability. Cosmos DB could improve its complex pricing models, integration with third-party solutions, and end-user documentation, with feedback also suggesting better cost management and support for complex queries.

Ease of Deployment and Customer Service: Couchbase Enterprise offers deployment flexibility across public, private, and hybrid clouds, including on-premises. However, customer support receives mixed reviews concerning responsiveness. Cosmos DB focuses on public cloud deployments with consistent support quality, though users note potential improvements in integration support and client communication.

Pricing and ROI: Couchbase Enterprise is considered reasonably priced due to low integration costs and high ROI in operational efficiency. It offers various licensing options but may incur additional costs for supplemental tools. Cosmos DB is seen as expensive with a complex resource unit-based pricing model, though it provides value through scalability and cloud-native benefits, often suiting larger enterprises due to high availability and performance costs, demanding prudent usage to maintain cost-effectiveness.

Effortless synchronization and reliable performance streamline everyday operations

It just works. I used other products and they didn't do what Couchbase does. It works out of sight once everything is set up. When the user makes changes on their list in the app on their mobile phone, it syncs straight away. If there's an internet interruption, it resumes as soon as internet is available. I didn't have to do anything as a developer.It's great because it's very different from MySQL where you have to update tables. With document type databases, you just say there's a new element in your document, and that's fine. It's really good to use.

reviewer2724105

Senior Director of Product Management at a tech vendor with 1,001-5,000 employees

Provides super sharp latency, excellent availability, and the ability to effectively manage costs across different tenants

For integrating Microsoft Azure Cosmos DB with other Azure products or other products, there are a couple of challenges with the current system. Right now, the vectors are stored as floating-point numbers within the NoSQL document, which makes them inefficiently large. This leads to increased storage space requirements, and searching through a vast number of documents in the vector database becomes quite costly in terms of RUs. While the integration works well, the expense associated with it is relatively high. I would really like to see a reduction in costs for their vector search, as it is currently on the expensive side. The areas for improvement in Microsoft Azure Cosmos DB are vector pricing and vector indexing patterns, which are unintuitive and not well described. I would also like to see the parameters of Fleet Spaces made more powerful, as currently, it's somewhat lightweight. I believe they've made those changes intentionally to better understand the cost model. However, we would like to take a more aggressive approach in using it. One of the most frustrating aspects of Microsoft Azure Cosmos DB right now is that you can only store one vector per document. Additionally, you must specify the configuration of that vector when you create an instance of Microsoft Azure Cosmos DB. Once the database is set up, you can't change the vector configuration, which is incredibly limiting for experimentation. You want the ability to try different settings and see how they perform, as there are numerous use cases for storing more than one vector in a document. While interoperability within the vector database is acceptable—for example, I can search for vectors—I still desire a richer set of configuration options.
