Collecting compliance data has become more efficient while managing unstructured inputs for reporting
The features that I find most valuable within Microsoft Azure Cosmos DB are probably the cost, as the cost optimization is good. The storage and queryability are good for what we're doing; it's a lot of unstructured data, so having a platform to put that in and then be able to harvest that data out for the reporting we do is essential. In terms of cost saving, it was probably easily 30 to 40% cheaper than doing a standard SQL, which is what we saw just on piloting and getting in there. We were initially thinking 20 to 25%, but we were probably more at the 35 to 40%. We are using Microsoft Azure Cosmos DB's hybrid search today. The value that it has added to my AI or search workloads is that I think it's optimized that process and made it easier. We have a lot of unstructured data coming from different dissimilar systems and different data sources, so correlating those things together and making sense of it has been very beneficial. Microsoft Azure Cosmos DB has had pretty good performance with searching through large amounts of data; it's been fast, and we haven't seen a lot of performance degradation while building larger queries and bringing in a large set of data. The dynamic auto-scale or serverless model from Microsoft Azure Cosmos DB has helped reduce costs and operational effort; however, it's hard to quantify how that plays out since you're using a shared service. It shifts my focus away from building, managing, and upgrading to adding value.

Handles large data volumes effectively but connection issues require attention
The Oracle NoSQL solution is used primarily for storing data for our web applications. We work alongside the DBA team for this purpose, given that specific departments manage aspects of its use. We choose it specifically to handle large scales of data, such as in one of our bank customer's scenarios using more than nine hundred gigabytes of data.

Quotes from Members

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

Pros

"We have both our SaaS app and the analytical side running without throttling issues."
"It's highly scalable and supports consistency, security, and multiple security options."
"Microsoft Azure Cosmos DB is very fast. Data retrieval and data storage are very quick."
"Reading and inserting data into Microsoft Azure Cosmos DB is a very smooth process."
"I would recommend Microsoft Azure Cosmos DB to other users without hesitation."
"The biggest benefit of Microsoft Azure Cosmos DB is the general cloud model that Azure gives you, providing more flexibility from a cost and data perspective while offering reasonable pricing and the best security solutions with zero trust protection, and with Azure you can start small and grow as you need."
"The most valuable aspect of Cosmos DB is its performance."
"The benefits of Microsoft Azure Cosmos DB were immediate for us."
"Try it! You’ll be impressed."
"NoSQL has high availability; I think it's perfect from a technical perspective, and it's quick to run and go."
"The product meets expectations when it comes to stability."
"With Oracle NoSQL, our clients have a highly scalable, simple to set up database that performs very well when data is organized correctly from the beginning."
"The tool is easy to learn."
"So far, we find stability to be very reasonable, it is dependable and we do not have any big issues."
"We have a support agreement with Oracle, ensuring full support for the product. It is crucial for our public-facing features. Oracle NoSQL is easy to manage and has fast data retrieval. Its compatibility with Oracle Database is seamless, making integration between NoSQL and relational databases smooth and effortless. Oracle NoSQL and NoSQL data replication in our environment works efficiently. Oracle fully supports it, and we can easily configure and manage authentication for the NoSQL database."
"Oracle NoSQL is pretty scalable."
 

Cons

"Because there is no local way of doing things, Azure Cosmos DB will always be considered expensive."
"We would like to see advancements in AI with the ability to benchmark vector search capabilities, ensuring it answers questions accurately. During our initial implementation, we faced challenges with indexing and sorting, which are natively available in other offerings but required specific configurations in Cosmos."
"Microsoft Azure Cosmos DB can be improved by providing more fine-grained control over certain aspects, such as connections and threads. There could be more control over how many connections are made."
"Azure Cosmos DB is generally a costly resource compared to other Azure resources. It comes with a high cost."
"Our use case was a failure with Microsoft Azure Cosmos DB, and we do not have any other opportunity to use Microsoft Azure Cosmos DB."
"The size of the continuation token in Azure Cosmos DB should be static rather than increasing with more data, as it can lead to application crashes. They should use a static key size."
"Slight enhancements in integration interfaces, expanded dashboard functionalities, and broader use-case support would be beneficial."
"It's still new, and good training resources are harder to find. Even the most recent books on Cosmos DB are several years old, which is ancient in IT terms."
"The installation is difficult."
"I would rate Oracle NoSQL six or 6.5 out of ten based on my experience."
"We've had some issues with stability. During our testing, we were able to drop an entire database by writing huge amounts of data."
"Oracle could improve how NoSQL works in containers. I don't think NoSQL needs any new features, but I want to see new features in the Oracle Cloud Infrastructure. I would like to see some improvements in OCI's building options."
"Focusing on making the administration easier compared to other solutions like MongoDB could be beneficial. Simplifying the administrative tasks could enhance the user experience."
"The main areas that need improvement with NoSQL are in the area of big data and user-friendly presentation."
"Personally, I’d like to see some improvements in the monitoring UI for it."
"You will get high performance when you organize your data correctly at the beginning. Otherwise, there are instability issues."
 

Pricing and Cost Advice

"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."
"Azure is a pay as you go subscription."
"We are not consuming so much yet since we are at the beginning of using this solution. I would rate the pricing of Microsoft Azure Cosmos DB a six out of ten."
"Microsoft provides fair pricing."
"The pricing for Cosmos DB has improved, particularly with the new pricing for Autoscale."
"It is expensive. The moment you have high availability options and they are mixed with the type of multitenant architecture you use, the pricing is on the higher end."
"It is cost-efficient as long as you understand the right setup to optimize usage. Knowing the data needs of the organization and adjusting the Microsoft Azure Cosmos DB usage accordingly helps save costs, but if you don't know, you could end up spending more than necessary."
"Cosmos DB is expensive compared to any virtual machine based on conventional RDBMS like MySQL or PostgreSQL."
"The product is expensive and Oracle could work to lower the licensing cost."
