Real-time customer analytics has boosted performance and simplified flexible JSON operations
I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella. I would say that there is a need for developer experience enhancements, including a simpler user interface, better debugging, SQL++ guidance, and more visibility into granular workload-level costs while reporting. Couchbase Capella can improve the accuracy and reliability of its AI output. Though it is not guaranteed that the large language model answer will be correct, improvements can be made by grounding the large language models and controlling parameters such as temperature to provide better results.

Real-time messaging has transformed customer updates and now powers responsive AI experiences
The primary benefits of Microsoft Azure Cosmos DB include horizontal scalability. The main advantage is that it handles data growth without requiring database redesign when traffic increases. Low latency access is another key benefit, as read and write operations are very fast, which is extremely helpful for real-time applications. Flexibility is also valuable because Microsoft Azure Cosmos DB uses JSON schema format, which contrasts with traditional table schemas that require time-consuming changes. In modernization scenarios where client requirements change rapidly, Microsoft Azure Cosmos DB offers more flexible schema design. High availability is another important feature, as it is well-suited for business-critical systems. My overall experience using Microsoft Azure Cosmos DB with other Azure services shows that it is more flexible compared to SQL Database and more readable because of its JSON format, making it easy to understand. It is more interactive because viewing the Microsoft Azure Cosmos DB schema clearly shows what is happening in the application and what will be achieved. In contrast, SQL requires writing many queries to obtain details, making Microsoft Azure Cosmos DB more suitable and flexible. My team's experience developing with Microsoft Azure Cosmos DB SDKs and APIs has been very comfortable and easy to implement. We are currently migrating .NET applications to Python-based AI solutions using Copilot, where we performed reverse engineering and are moving to forward engineering. We use APIs to connect with Microsoft Azure Cosmos DB and manage database containers and items, performing CRUD operations such as create, delete, and read operations, and querying JSON. We are using REST APIs with Python-based solutions, with a service layer and Microsoft Azure Cosmos DB integration.

Quotes from Members

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

Pros

"The initial setup was straightforward."
"For specifics, I can say that performance is 80% faster, with a four-fold increase in throughput requests and application availability uptime rising from 99.9% to 99.9999%, and the application can now handle three times more traffic."
"The way the nodes are managed is interesting."
"I would rate it a ten out of ten for stability."
"The most valuable features of Microsoft Azure Cosmos DB include the TTL, the ability to scale up and down as needed, and geo-replication, which comes out of the box."
"The graphical representation of data is the most valuable feature of the solution."
"Microsoft Azure Cosmos DB has positively impacted my organization by reducing the operational effort required to manage scalable NoSQL workloads and making it easier to support applications as data volumes and users grow."
"I would recommend Cosmos. It made our lives a lot easier. There's not a big learning curve in order to understand the structure and how to use it."
"Microsoft Azure Cosmos DB is easy to use and implement for application programmers."
"One valuable feature of Microsoft Azure Cosmos DB is partitioning. Its performance is very nice."
"The customer gave us the feedback that they are able to easily find the data they are looking for. It is very quick."
 

Cons

"The product could be improved by including a log section for tracking activities, enhancing database integration, and providing more transparency regarding pricing and monitoring activities."
"I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella."
"Rebalancing could be improved."
"Once you create a database, it calls the container, and then items show up. A better description and more guidance would help because the first time I created it, I didn't understand that a container is similar to a table in SQL."
"One of the primary challenges with Cosmos DB as a non-relational data store is the careful data modeling required due to the lack of collection-level joins when using the SQL API."
"We should have more freedom to tweak it and make our own queries for non-traditional use-cases."
"The solution cannot join two databases like Oracle or SQL Server."
"The RUs still appear to be a black box for everyone. Even though they explain read and write RUs, it remains unclear for many users."
"There's a little bit of a learning curve because I was new to Azure. But once you learn the tool, it's pretty straightforward."
"I would like to see certain improvements and enhancements in Microsoft Azure Cosmos DB."
"Microsoft Azure Cosmos DB's performance could be better. In large volumes of documents, the querying process becomes slow and complicated."
 

Pricing and Cost Advice

Information not available
"Cosmos DB is expensive compared to any virtual machine based on conventional RDBMS like MySQL or PostgreSQL."
"Cosmos DB is a PaaS, so there are no upfront costs for infrastructure. There are only subscriptions you pay for Azure and things like that. But it's a PaaS, so it's a subscription service. The license isn't perpetual, and the cost might seem expensive on its face, but you have to look at the upkeep for infrastructure and what you're saving."
"The pricing and licensing model was initially difficult to understand, but as soon as I learned what was going on and how it was priced, it was pretty easy."
"Pricing is one of the solution's main features because it is based on usage, scales automatically, and is not too costly."
"Cosmos DB is a highly cost-optimized solution when used correctly."
"Cosmos DB is a managed offering, so its cost is understandably higher."
"Its pricing is higher compared to solutions like Aerospike. However, it is justified because of the out-of-the-box features that are provided. The availability and resiliency that we have make it worth the price."
"Our experience with the pricing and setup cost is that it aligns with what we expect based on the pricing we see. However, I would absolutely like it to be less if possible."
