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

"Some of the best features of Microsoft Azure Cosmos DB are that it could scale, and we could still use SQL language."
"It is a cloud-based solution that is easy to deploy, easy to access, and provides users with more features compared to other clouds like AWS and GCP."
"Microsoft Azure Cosmos DB offers the response times needed for advanced analytics applications."
"We chose Azure Cosmos DB initially because of the type of data that we needed to store. We have a schema that is very nondeterministic and flexible. It is always changing based on whatever data we need to acquire from different devices, so we needed a document store with a flexible schema."
"When all resources are at the same point, there is no lag and in production we have experienced minimal issues, with the project live for two years without any database problems."
"Azure Cosmos DB's resiliency is valuable. It is available in every Azure region, allowing quick information storage and retrieval. We can partition it to improve indexing, enabling us to retrieve information and recreate website content quickly."
"The most valuable feature of Microsoft Azure Cosmos DB is its ability to handle concurrency and consistency."
"The connectors, such as the MongoDB connector and the integration with SQL, are incredibly valuable."
"Neo4j AuraDB has impacted my organization positively as it was extremely useful to prototype the knowledge graphs for this digital twin platform."
"Integrating the front-end language with Neo4j AuraDB is a very easy process."
"Neo4j Aura is a technically strong and capable managed graph database, and it has been valuable for research and production use."
"From my experience, I particularly like the professional version. Initially, developers often start with the free variant. Once the project grows, we switch to the professional version, which offers multiple databases, expanded memory, and better scalability. This allows us to handle more data and use cloud scaling features."
"The best features Neo4j AuraDB offers are that it is easy to quickly build a solution with their tooling."
"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."
"Neo4j helped us decrease our development time and also the storage level, which was very much helpful."
"The tool is easy to use."
 

Cons

"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."
"There were instances where the DB was not responding, and we lost some part of our business due to that."
"The first one is the ability to assign role-based access control through the Azure portal for accounts to have contributor rights."
"Azure Cosmos DB is generally a costly resource compared to other Azure resources. It comes with a high cost."
"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."
"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."
"Microsoft Azure Cosmos DB's pricing model is complicated, which people don't understand."
"It should offer a simple user interface for querying Microsoft Azure Cosmos DB."
"For me, the thing that was the most painful is the seven-day expiration where you need to reactivate or restart it."
"A production database service was suspended without prior notice, and a platform-side marketplace transition effectively forced migration."
"Some features can help if they can visualize graphs better."
"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."
"There’s room for improvement in Neo4j AuraDB, especially on the developer side. The learning curve can be steep, and the interface for developing and pushing code can be unnecessarily complex. It might be beneficial to simplify this process to help developers ramp up more quickly. Working with graph databases like Neo4j can be more challenging than standard databases, particularly for juniors and those new to graph technology. Streamlining the development process could make it easier for new users to get up to speed. This would be particularly useful for teams with less experience in graph databases. If I could add a feature to Neo4j AuraDB, I’d focus on improving the Bloom interface. It’s excellent for visualizing smaller datasets, but navigating through it becomes challenging as the data grows—say, past 100,000nodes. The interface works well for beginners but doesn’t scale effectively for more advanced users of large datasets. I want a UI that bridges the gap between the easy-to-use Bloom interface and more complex, text-based tools. This would help manage larger datasets more efficiently and improve performance."
"Cost is another factor to consider, as Neo4j AuraDB can be relatively expensive and resource-intensive compared to some alternatives."
"During the product's initial setup phase, there were some issues due to disconnections in the tool's network."
"In terms of AuraDB, the conversations have always been around scalability."
 

Pricing and Cost Advice

"Cosmos DB gave us three accounts for $400. We pay according to the usage."
"Pricing, at times, is not super clear because they use the request unit (RU) model. To manage not just Azure Cosmos DB but what you are receiving for the dollars paid is not easy. It is very abstract. They could do a better job of connecting Azure Cosmos DB with the value or some variation of that."
"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 cost is the biggest limitation of this solution."
"Cosmos DB is a managed offering, so its cost is understandably higher."
"It seems to have helped significantly. We were using a different database system previously, and one of the reasons for acquiring Microsoft Azure Cosmos DB was cost."
"Its pricing is not bad. It is good."
"Cosmos DB is cost-effective when starting but requires careful management."
"The tool's enterprise edition is very expensive."
"I am using an open-source version of Neo4j AuraDB."
"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."
