Consistent performance and seamless cloud integration enhance analytics capabilities while reducing management complexity
One point for improvement in Google Cloud Bigtable is that people have confusion in mapping. There are many similar products available, and Google has managed services for similar products as well. It would be easier if the journey of knowing when to use Google Cloud Bigtable versus other Cloud SQL and alternates such as Cloud Spanner is made clearer for users. Regarding additional functionality for Google Cloud Bigtable, I am uncertain if LLMs can be integrated or if Google Cloud Bigtable can act as a vector store for LLM-specific use cases where we are interacting or using generative AI capabilities.

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.

Quotes from Members

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

Pros

"I like the drive and the support of this program."
"Bigtable is faster than other competitors in the market. It helps us collate all the data, and the security features are great. The latency is low, and the computation speed is fantastic. Bigtable is also a managed service, so you don't have to worry about anything aside from analyzing the data ingested."
"The solution is very stable; we've never experienced bugs or glitches, we haven't had crashes, and it works well and as expected 100% of the time."
"Bigtable is very user-friendly where streaming data is required."
"Stability-wise, it is a simple solution. I rate the solution's stability a ten out of ten."
"This solution is much more scalable than more traditional databases - at least the ones we are aware of."
"The most valuable feature is the backup and replication service."
"Scalability-wise, I rate the solution a ten out of ten."
"I appreciate Microsoft Azure Cosmos DB's robust document management and consistent availability."
"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."
"It is a scalable product."
"Microsoft Azure Cosmos DB is a good solution for distributed application requirements. We can perform multi-modeling."
"Microsoft Azure Cosmos DB simplifies the process of saving and retrieving data."
"The solution's read capacity and write access functions are very fast so users don't have to wait when fetching or displaying data on a screen."
"From a global distribution perspective, Microsoft Azure Cosmos DB is good and easy to handle."
"Having a NoSQL solution that can do that in a 100 percent Azure shop is the best fit we could want."
 

Cons

"The program is rather expensive - it depends on the size of your data."
"The cost of this product is too expensive."
"I've used Bigtable for about three or four years."
"When it comes to complex queries, a user can't get any help from a drop-down box and pick columns. It would be great if some improvements could be made in the aforementioned area concerning the solution."
"It would be nice if the pay-as-you-go license were a little cheaper."
"This product needs better security and transparency, and the price should be reduced."
"The pricing of the solution needs to be improved."
"Pricing-wise, I find GCP can be a little costly, so I would rate it a 3.5."
"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."
"I have to say technical support is not very good as it takes too long. Sometimes it can take them two or three days to respond to your ticket."
"I hope they improve the service. Before last year, improvements on Cosmos DB were very slow."
"The auto-scaling feature adjusts hourly. We have many processes that write stuff in batches, so we must ensure that the load is spread evenly throughout the hour. It would be much easier if it were done by the minute. I'm looking forward to the vector database search that they are adding. It's a pretty cool new feature."
"It is easy to use, but optimization has been a mixed experience. It has been more of trying to figure out how to do so. We have not found much support there, so we have to come up with our own way of optimizing it in different ways. That is one area of improvement."
"A further simple application is required for Brazil."
"There are some disadvantages as it is costly compared to other NoSQL databases. It has a complex pricing model and has a strict partitioning strategy."
"Because there is no local way of doing things, Azure Cosmos DB will always be considered expensive."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"The Cosmos DB pricing model, initially quite complicated, became clear after consulting with Azure Advisor, allowing us to proceed with confidence."
"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 gave us three accounts for $400. We pay according to the usage."
"Its price is in the middle, neither too low nor too high."
"Microsoft Azure Cosmos DB is moderately priced, where it is neither expensive nor cheap."
"The price of Microsoft Azure Cosmos DB could be a bit lower."
"When we've budgeted for our resources, it's one of the more expensive ones, but it's still not very expensive per month."
"The pricing for Cosmos DB has improved, particularly with the new pricing for Autoscale."
