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.

Cloud database has reduced infrastructure effort and now lets us focus on clean transactional data
Currently, we have not identified significant improvement areas for SkySQL. However, enhanced AI functionality would be beneficial. We use AI in Snowflake but not in SkySQL. If SkySQL could write SQL queries automatically using AI or improve SQL query performance, this would be valuable for future use cases.When comparing SkySQL to other databases such as Databricks and Snowflake, these platforms offer more AI-related functionality and data lineage capabilities, allowing visibility of the complete data journey from source to target. SkySQL currently lacks data lineage functionality. Since we transform data using stored procedures and views, implementing data lineage functionality would help us track the complete journey of data from source through all intermediate transformation steps to the final layer. I rate SkySQL an eight out of ten.

Quotes from Members

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

Pros

"Change feed is a pretty amazing feature. Once you make the changes, they are quickly read for you, and then you also have geo-replication. You can do a lot of things in your region, and the same regions can be replicated all over the world."
"Microsoft Azure Cosmos DB offers the response times needed for advanced analytics applications."
"The most valuable feature of Microsoft Azure Cosmos DB is its real-time analytics capabilities, which allow for turnaround times in milliseconds. This is crucial for applications like fraud detection."
"Cosmos DB makes life easier because if we want to use Mongo-type data, or Cassandra-type data, or maybe even just a simple cable storage-type data, then graph, there are multiple ways to do this."
"The biggest benefit of Microsoft Azure Cosmos DB is the general cloud model that Azure gives you, providing more flexibility from a cost and data perspective while offering reasonable pricing and the best security solutions with zero trust protection, and with Azure you can start small and grow as you need."
"The peace of mind that Microsoft Azure Cosmos DB provides regarding global distribution is invaluable."
"The searching capability is exceptional. It is very simple and incomparable to competitors."
"Cosmos DB's greatest strengths are its easy setup and affordability, especially for those who understand its usage."
"We never face performance issues, and backup and scalability are all managed automatically, which has significantly improved our SLA."
"SkySQL is easy to use and has reliable performance, offering scalability and fast execution."
"In my experience, the best feature that SkySQL offers is a fully managed database service which reduces operational overhead, along with its high availability and automatic failover for business-critical applications, and its scalability to handle growing data volumes and overloads, plus automated backups and disaster recovery capabilities."
"Compared with all of these options, we concluded that SkySQL is one of the best solutions addressing those criteria."
 

Cons

"Better documentation on how to integrate with other components would be helpful because I was struggling with this."
"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."
"The size of the continuation token in Azure Cosmos DB should be static rather than increasing with more data, as it can lead to application crashes. They should use a static key size."
"One area for improvement is the ease of writing SQL queries and stored procedures in Microsoft Azure Cosmos DB. Writing an SQL query and a stored procedure on top of that is a little challenging."
"It is not as easy to use as DynamoDB."
"The only problem I face is more with infrastructure as code templates that don't cover everything that can be set up or configured on the portal, requiring some manual work which is additional work for us."
"Azure Cosmos DB is generally a costly resource compared to other Azure resources. It comes with a high cost."
"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."
"More end-to-end deployment guides, additional reference architectures, dashboards, and more proactive performance tuning recommendations would make the platform even easier to adapt and manage."
"I believe one area for improvement would be more advanced monitoring and reporting features."
"It is still early in our evaluation of SkySQL, so we do not have major concerns, but if anything, we would like to see even better documentation, onboarding guidance, and monitoring capabilities to make adoption and ongoing management easier."
"When comparing SkySQL to other databases such as Databricks and Snowflake, these platforms offer more AI-related functionality and data lineage capabilities, allowing visibility of the complete data journey from source to target."
 

Pricing and Cost Advice

"Cosmos should be cheaper. We actually intend to stop using it in the near future because the price is too high."
"It is cost-effective. They offer two pricing models. One is the serverless model and the other one is the vCore model that allows provisioning the resources as necessary. For our pilot projects, we can utilize the serverless model, monitor the usage, and adjust resources as needed."
"Azure Cosmos DB's pricing is competitive, though there is a need for more personalized pricing models to accommodate small applications without incurring high charges. A suggestion is to implement dynamically adjustable pricing that accounts for various user needs."
"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."
"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."
"Because of the lack of understanding about RUs, the costs become unpredictable. It sometimes goes over the budget."
"Cosmos DB's pricing structure has significantly improved in recent months, both in terms of its pricing model and how charges are calculated."
"The Cosmos DB pricing model, initially quite complicated, became clear after consulting with Azure Advisor, allowing us to proceed with confidence."
