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 helped improve our organization's search result quality significantly when we started using it about eight years ago."
"The most valuable aspect of Cosmos DB is its performance."
"Overall, I would rate it a nine out of ten with the only significant issue being the partitioning key functionality."
"Cosmos is preferred because of its speed, robustness, and utilization."
"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 standout features are its ability to do data compression easily and the ability to scale horizontally."
"The best feature of Microsoft Azure Cosmos DB is API access, which makes it very easy to interact with the database without needing to write queries."
"For example, we have people spread across multiple locations; if they update data in Australia, we can access it in another location within a fraction of a second."
"Integrating the front-end language with Neo4j AuraDB is a very easy process."
"Overall, Neo4j AuraDB has increased our deployment speed, improved system stability, and lowered operational costs, making our entire database stack more efficient and scalable."
"The speed of recommendation really increased after we converted the first graph we had to a Neo4j AuraDB graph, as the response time reduced from about 5 to 10 seconds to about 1 to 5 seconds in most cases."
"The tool is easy to use."
"Neo4j AuraDB has impacted my organization positively as it was extremely useful to prototype the knowledge graphs for this digital twin platform."
"The most beneficial things in terms of AuraDB are its speed, its good pricing, the multi-cloud availability."
"I like the idea of graphs and nodes and the possibilities Neo4j AuraDB offers."
"Neo4j helped us decrease our development time and also the storage level, which was very much helpful."
 

Cons

"The tool's pricing is expensive."
"For the third-party driver support they are currently providing, they need to ensure it stays up to date with the market throughout development."
"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."
"It would be nice to have more options to ingest the data, for example, more file options or more search options. Currently, you can use JSON, but if there were other file types you can use for data ingestion, that would be nice."
"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."
"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."
"A limitation in Azure Cosmos DB is the 2 MB document size. Developers need more systemic support in chaining multiple documents if more than 2 MB is required."
"A minor improvement would be enabling batch operations through the UI. Currently, to delete all documents in a collection, we must use an API, which some of my team finds inconvenient for admin tasks."
"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."
"During the product's initial setup phase, there were some issues due to disconnections in the tool's network."
"Cost is another factor to consider, as Neo4j AuraDB can be relatively expensive and resource-intensive compared to some alternatives."
"A production database service was suspended without prior notice, and a platform-side marketplace transition effectively forced migration."
"I've experienced it crashing a few times, so stability could be better."
"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."
"For me, the thing that was the most painful is the seven-day expiration where you need to reactivate or restart it."
"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."
 

Pricing and Cost Advice

"Azure is a pay as you go subscription."
"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."
"Cosmos DB is expensive compared to any virtual machine based on conventional RDBMS like MySQL or PostgreSQL."
"Its pricing structure is quite flexible."
"Pricing is mid- to high-end."
"Its price is very good for the basic stuff. When you go to a more complicated use case, especially when you need replication and availability zones, it gets a little costly."
"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."
"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."
"I used the free tier."
"The tool's enterprise edition is very expensive."
"I am using an open-source version of Neo4j AuraDB."
"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."
