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.

Graph-based knowledge has streamlined interconnected support queries and improves debugging
If I say so, how Neo4j AuraDB can be improved, at a very minute level, I can say that the graphs, if I want things to be in three dimensions. Currently we get them in two dimensions. When we scale this up, the maps become complicated, and in two dimensions things can be complex in visualization purposes. When we put in filters, the connections also vanish sometimes. The visualization side is something that could help. Additionally, if there is a voice search capability, which we can implement, that would add more functionality. With so much AI involved, AI could be helpful if we put in our data and enable it to give insights from the networks already developed in the graph. Some insights could be shown to our client, indicating that their data already contains meaningful insights, which could serve an analytical purpose. Voice search on the graph would be easily understandable and provide faster outputs to the customer.

Quotes from Members

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

Pros

"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."
"The solution's enhanced performance is its most valuable aspect."
"The best features of Microsoft Azure Cosmos DB are the way it maintains the data in partitions and its retention policies."
"Cosmos DB has helped us by providing faster response times for everything, which significantly improved our search results quality."
"It is a NoSQL database."
"One valuable feature of Microsoft Azure Cosmos DB is partitioning. Its performance is very nice."
"The dynamic autoscale or serverless model of Microsoft Azure Cosmos DB has indeed helped reduce our costs and operational effort by allowing us to scale horizontally in a straightforward manner according to our needs."
"It is easy to use because you don't need to know much about Cosmos DB or have prior experience."
"Neo4j AuraDB has impacted my organization positively by improving query performance."
"I like the idea of graphs and nodes and the possibilities Neo4j AuraDB offers."
"Integrating the front-end language with Neo4j AuraDB is a very easy process."
"The most valuable features of Neo4j AuraDB include its flexible data model and broad language support."
"The stability and reliability of Neo4j AuraDB have been very good, as it is a managed service with a 99.95% SLA, so the stability is impressive and I have not faced any outages when the product stopped working abruptly during my tenure of one and a half years."
"The most beneficial things in terms of AuraDB are its speed, its good pricing, the multi-cloud availability."
"Neo4j AuraDB has impacted my organization positively as it was extremely useful to prototype the knowledge graphs for this digital twin platform."
"Overall, Neo4j AuraDB has increased our deployment speed, improved system stability, and lowered operational costs, making our entire database stack more efficient and scalable."
 

Cons

"Cosmos DB should continue evolving in AI features. We expect Cosmos DB to lead on that. There is potential for improved security features, which is important for data storage, especially for Dell Technologies. We must ensure data security remains the top priority."
"I think Microsoft Azure Cosmos DB can be improved by providing continuous backup for multi-region rights. I believe it's available for non-multi-region rights, but there are many features that are locked behind continuous backup that I can't use because it's not enabled yet."
"Azure Cosmos DB could be better for business intelligence and analytical queries."
"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."
"The support tickets are not cheap."
"There were instances where the DB was not responding, and we lost some part of our business due to that."
"Azure Cosmos DB for NoSQL has a less developed interface and fewer SQL commands than MongoDB, and its community support is also smaller."
"The solution cannot join two databases like Oracle or SQL Server."
"I've experienced it crashing a few times, so stability could be better."
"Some features can help if they can visualize graphs better."
"For me, the thing that was the most painful is the seven-day expiration where you need to reactivate or restart it."
"If I say so, how Neo4j AuraDB can be improved, at a very minute level, I can say that the graphs, if I want things to be in three dimensions."
"Neo4j AuraDB is a very strong platform, but there are a few areas for improvement. The pricing model can be somewhat unpredictable as your database grows, since costs scale with node and relationship counts."
"In terms of AuraDB, the conversations have always been around scalability."
"During the product's initial setup phase, there were some issues due to disconnections in the tool's network."
"A production database service was suspended without prior notice, and a platform-side marketplace transition effectively forced migration."
 

Pricing and Cost Advice

"The RU's use case determines our license fees."
"The solution is very expensive."
"Pricing is one of the solution's main features because it is based on usage, scales automatically, and is not too costly."
"The pricing is perceived as being on the higher side. However, if you have large data operations, it might reduce costs due to performance efficiencies."
"Microsoft Azure Cosmos DB's licensing costs are monthly."
"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."
"Azure Cosmos DB's pricing is competitive, though there is a need for more personalized pricing models to accommodate small applications without incurring high charges. A suggestion is to implement dynamically adjustable pricing that accounts for various user needs."
"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."
"I am using an open-source version of Neo4j AuraDB."
"The tool's enterprise edition is very expensive."
"I used the free tier."
"Neo4j AuraDB is reasonably priced, especially considering it removes the need for cloud administration and associated costs. It's a good deal for the professional version, as it includes managed services, which reduces the overhead compared to setting up your own infrastructure. The cost can be higher for enterprise-scale projects, but that's often due to the scale and complexity of the project rather than the product itself. Startups sometimes overestimate their needs and jump to enterprise pricing too quickly, leading to higher costs than necessary."
