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.

Delivers superior search and data aggregation capabilities
Neo4j helps with advanced search needs, providing good search results and aggregates compared to MongoDB. Aggregating with MongoDB can be difficult; however, with Neo4j, it's easier. Aggregating data, backing up, and creating new clusters are user-friendly from the back end. In DevOps web deployment, we noticed no database issues. We created Docker instances and set them up efficiently, managing databases up to 50 gigabytes.

Quotes from Members

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

Pros

"Reading and inserting data into Microsoft Azure Cosmos DB is a very smooth process."
"The feature I have found most valuable in Microsoft Azure Cosmos DB is its scalability and speed."
"In Microsoft Azure Cosmos DB, one valuable feature is its ability to store data in multiple regions. If one region fails, it automatically switches to a healthy region, ensuring minimal latency and disaster recovery without impacting data latency in applications."
"Cosmos DB has helped us by providing faster response times for everything, which significantly improved our search results quality."
"Microsoft Azure Cosmos DB is very easy to use."
"The scalability and ease of use with the APIs of Microsoft Azure Cosmos DB have allowed us to meet our customers' expectations pretty easily with little barrier to entry."
"It's highly scalable and supports consistency, security, and multiple security options."
"Microsoft Azure Cosmos DB helped improve our organization's search result quality significantly when we started using it about eight years ago."
"As a graph database, I am surprised at their performance and response time."
"It is good for search-based tasks, providing solid search results and aggregate results."
"Creates the ability to visualize outputs."
"Enables people to understand what the business problem is and how the technology helps."
"The solution's best feature is how it differs from traditional SQL databases. It's hard to map people and find those near me in SQL, which requires long, complex queries. Neo4j Graph Database makes this easier with simpler queries. It also supports more data types, like JSON, which SQL doesn't."
"It enables circumstances which would have been a complex problem to be simplified."
"Neo4j helps with advanced search needs, providing good search results and aggregates compared to MongoDB."
"The graph modeling paradigm suits our data set well, where there may be orders of magnitude more connections between data points than data points themselves."
 

Cons

"Areas of improvement for Microsoft Azure Cosmos DB include indexing. While it makes data retrieval easier, it also increases costs. If there's a better way to improve indexing at a lower cost, that would be really helpful, but that's the major point for now."
"New features can be included and its stability can be further improved."
"Azure Cosmos DB could be better for business intelligence and analytical queries."
"In Microsoft Azure Cosmos DB, I would suggest improvements in security."
"There were instances where the DB was not responding, and we lost some part of our business due to that."
"One of the most frustrating aspects of Microsoft Azure Cosmos DB right now is that you can only store one vector per document."
"I hope they improve the service. Before last year, improvements on Cosmos DB were very slow."
"From a scalability perspective, the key database has to be optimized in a better way that can support auto-scaling architecture or scalability architecture."
"There are concerns about performance and whether the tool can necessarily scale to provide the solution."
"For me, when the tool was deployed on an on-premises model, it was a little bit difficult the first time."
"The tool could improve by having more resources, especially for Golang, which we use. It lacks good basic libraries and doesn't have an ORM (Object-Relational Mapping) tool, which many NoSQL databases have. We thought about building an ORM for the Neo4j Graph Database but are too busy."
"There are things I found unintuitive or difficult to understand, however I can't say this is a deficiency in the product and likely more a function of my relatively low experience."
"So far, we have not had any issues and are happy with the product in general."
"The only problem is that the community is quite small."
 

Pricing and Cost Advice

"Pricing is one of the solution's main features because it is based on usage, scales automatically, and is not too costly."
"Its pricing structure is quite flexible."
"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."
"Cosmos DB's pricing structure has significantly improved in recent months, both in terms of its pricing model and how charges are calculated."
"For the cloud, we don't pay for the license, but for the on-prem versions, we do pay."
"Microsoft Azure Cosmos DB is moderately priced, where it is neither expensive nor cheap."
"With heavy use, like a large-scale IoT implementation, you could easily hit a quarter of a million dollars a month in Azure charges if Cosmos DB is a big part of it."
"Pricing is mid- to high-end."
"The solution is open source so that you can use it for free. They also offer an enterprise version with its billing. If your company is earning well, I suggest using the enterprise version. Otherwise, you can deploy it on your own cloud and pay based on usage."
"The tool is not expensive."
