Executive SummaryUpdated on Jan 25, 2026

Microsoft Azure Cosmos DB and Chroma are database solutions competing in the scalable and efficient database solutions category for business needs. Chroma's focus on modern analytics capabilities provides a competitive edge for data-intensive applications.

Features: Microsoft Azure Cosmos DB delivers globally distributed, multi-model data handling capabilities with strong consistency options and low latency. Chroma enhances these offerings with sophisticated data modeling capabilities, a strong emphasis on analytics, and advanced AI integration. While Microsoft Azure Cosmos DB sets a standard in comprehensive feature offerings, Chroma's advanced analytical focus appeals to specific data-driven needs.

Ease of Deployment and Customer Service: Microsoft Azure Cosmos DB integrates seamlessly with Microsoft’s cloud ecosystem and provides extensive documentation, allowing businesses already familiar with Microsoft services to experience smoother deployment. Chroma offers a streamlined setup and emphasizes easy integration of analytics features. Both provide strong customer support; however, Microsoft benefits from an expansive cloud infrastructure support network.

Pricing and ROI: Microsoft Azure Cosmos DB is perceived as a high-cost solution, justifying its expense with a robust feature set suitable for large enterprises interested in global reach. In contrast, Chroma is seen as a more cost-effective solution with lower upfront costs, appealing to smaller businesses focused on analytics. Whereas Microsoft Azure Cosmos DB justifies its pricing with comprehensive features, Chroma ensures a significant ROI through specialized data capabilities and reduced initial financial obligations.

Used for RAG (Retrieval-augmented generation) and provides good documentation

If I have to deploy my application in a scalable environment with lots of data and users, I sometimes need to create multiple instances of my database or have a distributed database across different machines. Using Kubernetes, I can quickly increase the horizontal spread of Milvus because it is containerized and readily available. I don't have to do anything by myself. New users can go to Chroma's 'Get Started' page and follow it like a tutorial. Then, they will be ready to use the solution. Chroma has helped us reduce the overall project post production time. Overall, I rate the solution an eight out of ten.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It's very easy to set up and runs easily."

"The solution's most valuable feature is its documentation, which allows new users to easily learn, deploy, and use it."

"The standout features are its ability to do data compression easily and the ability to scale horizontally."

"The ability to scale automatically is very valuable. Additionally, multi-region support automatically synchronizing to a different region for multi-region applications is a cool feature. It's more of a lift with other databases to configure that extra region and set up replication, even if it's on the cloud. With Azure, it's just a button click. It's that simple."

"The most valuable feature of Azure Cosmos DB is its scalability. That is the biggest reason I use Azure Cosmos DB."

"The solution's read capacity and write access functions are very fast so users don't have to wait when fetching or displaying data on a screen."

"Reading and inserting data into Microsoft Azure Cosmos DB is a very smooth process."

"Microsoft Azure Cosmos DB has reduced our total cost of ownership by about half, allowing us to sell our product for about half of what we were selling it before, and Microsoft Azure Cosmos DB is probably 70% of the reason why that's true."

"Cosmos DB is effective at handling large queries."

"Some of the best features of Microsoft Azure Cosmos DB are that it could scale, and we could still use SQL language."

Cons

"The hybrid algorithm needs improvement."

"I think Chroma doesn't have a ready-made containerized image available."

"In Microsoft Azure Cosmos DB, I would suggest improvements in security."

"The query is a little complex. SQL server should have more options. But the query should be better."

"The topic of RU consumption needs better documentation. Now that Microsoft has partnered with different LLM organizations, such as OpenAI, a bot could guide us through different metrics present in Microsoft Azure Cosmos DB."

"Continuing to educate customers on how they can take better advantage of Microsoft Azure Cosmos DB without having to completely rewrite their entire application paradigm would be beneficial. They can help them understand that there are multiple options to interact with it. They do not necessarily have to start from scratch. They can refactor their existing application to be able to use it better."

"Its stability can be further improved."

"I would give a low rating to Microsoft support, as whenever I talked to them, I never got a solution. I had to guide them."

"There is room for improvement in their customer support services."

"There aren't any specific areas that need improvement, but if there were a way to achieve the right cosine similarity score without extensive testing, that would be very beneficial."

Pricing and Cost Advice

"The current version is an open-source."

"Microsoft provides fair pricing."

"Its price is in the middle, neither too low nor too high."

"Cosmos DB is cost-effective when starting but requires careful management."

"This cost model is beneficial because it allows for cost control by limiting resource units (RUs), which is ideal. However, for our needs, we can't engage with their minimum pricing, which ranges from 100 to 1,000 RUs. At the bare minimum, we need to use 4,000 RUs for a customer. I would like to find a way to gain some advantages from the lowest tier, particularly the ability to scale down if necessary. It would be helpful to have more flexibility in cost management at the lower end."

"When we've budgeted for our resources, it's one of the more expensive ones, but it's still not very expensive per month."

"The RU's use case determines our license fees."

"The customer had a high budget, but it turned out to be a little bit cheaper than what they expected. I am not sure how much they have spent so far, but they are satisfied with the pricing."

"From a startup point of view, it appears to be expensive. If I were to create my startup, it would not have the pricing appeal compared to the competition, such as Supabase. All those other databases are well-advertised by communities. I know there is a free tier with Azure Cosmos DB. It is just not well advertised."
