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

"Stability-wise, it is a simple solution. I rate the solution's stability a ten out of ten."
"I like the drive and the support of this program."
"Scalability-wise, I rate the solution a ten out of ten."
"The solution is very convenient."
"The most valuable feature is the backup and replication service."
"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 main benefit I receive from Google Cloud Bigtable is the managed service part."
"Bigtable is very user-friendly where streaming data is required."
"Overall, I would rate it a nine out of ten with the only significant issue being the partitioning key functionality."
"It is one of the simpler databases to work with in terms of code management, tracking, and debugging due to its straightforward data storage and retrieval mechanisms."
"Microsoft Azure Cosmos DB simplifies the process of saving and retrieving data."
"Azure Cosmos DB helped improve the quality of our search results."
"Cosmos DB is stable and easy to use."
"The most valuable features include the global write capability, which allows customers to read and write across different regions simultaneously, enhancing performance and availability."
"Microsoft Azure Cosmos DB is a good solution for distributed application requirements. We can perform multi-modeling."
"The connectors, such as the MongoDB connector and the integration with SQL, are incredibly valuable."
 

Cons

"This product needs better security and transparency, and the price should be reduced."
"Pricing-wise, I find GCP can be a little costly, so I would rate it a 3.5."
"The cost of this product is too expensive."
"Improvement should be made as per customer recommended and requirements."
"I've used Bigtable for about three or four years."
"The pricing of the solution needs to be improved."
"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."
"The program is rather expensive - it depends on the size of your data."
"In Microsoft manufacturing, managers really need to know about the product."
"The biggest problem is the learning curve and other database services like RDS."
"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."
"The support tickets are not cheap."
"The model with autoscaling for RU is complicated to optimize RU consumption."
"Cosmos DB is expensive, and the RU-based pricing model is confusing."
"I had a challenging experience implementing the emulator with a Mac. I had to install the emulator in a Docker container because it is not natively compatible. A significant amount of time was spent researching how to enable HTTPS communication when connecting the container and the emulator."
"The UI should be improved since if you provide the option to query directly when signing into the Azure portal, it makes no sense if you have such a poor UI for querying that you can't even feed the reports correctly."
 

Pricing and Cost Advice

"I would like to see better pricing. It is not too expensive, but it isn't cheap either."
"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 gave us three accounts for $400. We pay according to the usage."
"Its pricing is higher compared to solutions like Aerospike. However, it is justified because of the out-of-the-box features that are provided. The availability and resiliency that we have make it worth the price."
"Azure is a pay as you go subscription."
"If you are a small organization or startup building from scratch without the Microsoft Startup Founder Club support, it could be expensive."
"This cost model is beneficial because it allows for cost control by limiting resource units (RUs), which is ideal. However, for our needs, we can't engage with their minimum pricing, which ranges from 100 to 1,000 RUs. At the bare minimum, we need to use 4,000 RUs for a customer. I would like to find a way to gain some advantages from the lowest tier, particularly the ability to scale down if necessary. It would be helpful to have more flexibility in cost management at the lower end."
"The price of Microsoft Azure Cosmos DB could be a bit lower."
"The solution is very expensive."
