Featured Reviews

PranavVighe - PeerSpot reviewer
Senior Consultant Data Engineer at IRT Digital Analytics
Real-time customer analytics has boosted performance and simplified flexible JSON operations
I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella. I would say that there is a need for developer experience enhancements, including a simpler user interface, better debugging, SQL++ guidance, and more visibility into granular workload-level costs while reporting. Couchbase Capella can improve the accuracy and reliability of its AI output. Though it is not guaranteed that the large language model answer will be correct, improvements can be made by grounding the large language models and controlling parameters such as temperature to provide better results.
Matthew Parker - PeerSpot reviewer
Ai Team Lead at Phoenix Software
Integrates with familiar tools and supports reliable data storage for AI applications
Microsoft Azure SQL Database can be improved overall by being able to compete with some of the features that come from things such as PostgreSQL. From my team's perspective in terms of building AI applications, more native integrations with some of the newer AI data types, such as vectors for storing embeddings, would be beneficial. I think all of that is coming. It is just a big product, so I think it is naturally a little bit behind the curve. However, that is not necessarily a bad thing because a lot of customers, because it has been around for so long, they trust it and they are willing to wait until those features become available.

Quotes from Members

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

Pros

"The way the nodes are managed is interesting."
"The initial setup was straightforward."
"For specifics, I can say that performance is 80% faster, with a four-fold increase in throughput requests and application availability uptime rising from 99.9% to 99.9999%, and the application can now handle three times more traffic."
"In my current role, I consider SQL Azure the leader for cloud-based RDBMS solutions, far ahead of any other cloud-based RBMS offering."
"The on-premise SQL Server licenses can be used since it is on Azure, so it's a significant savings for the customers."
"Its easy usage is the most valuable."
"The solution effectively handles storing and maintaining information in databases."
"The administration console in Azure, all in one is the most valuable feature."
"Overall, Azure SQL has been great. The ease of deployment and scalability are significant reasons we push our larger clients to Azure. We could throw the kitchen sink at the thing if we wanted."
"The interface is awesome."
"Microsoft Azure SQL Database scales well, allowing us to increase our compute level or add more instances as required."
 

Cons

"The product could be improved by including a log section for tracking activities, enhancing database integration, and providing more transparency regarding pricing and monitoring activities."
"Rebalancing could be improved."
"I believe that the documentation should be increased, and features such as vector AI search and other AI capabilities need improvement for Couchbase Capella."
"The Microsoft Azure SQL Database is not the latest version of Microsoft SQL Server; it's a really old engine that does not have the newest features, is very slow, and too expensive, so I really don't think it's a good solution for most cases, except when you specifically need to put your data on the cloud."
"There are compatibility issues that prevent Azure SQL Database from being a direct replacement for SQL Server running on a virtual machine. For instance, handling application-initiated DBCC commands is a challenge."
"They should also simplify the security in Azure. Integrating those components in terms of permissions and security is challenging for us."
"The pricing is actually complicated, and that is probably one downside of it."
"We have a very small database running on SQL Azure. We have not been able to load bigger systems on it."
"Some data types are not available on SQL Azure while it's available on SQL Server."
"We've had many concurrency issues with it, particularly with applications that do a lot of parallel processing."
"The price is very high, especially when you compare it to other solutions."
 

Pricing and Cost Advice

Information not available
"I would rate the pricing a seven out of ten."
"It is expensive for us. We are looking for something less expensive and thinking of migrating the whole system."
"I would like it to be cheaper, but comparatively, it is reasonably priced."
"The pricing is flexible and can be adapted based on our requirements but the pricing options are complex especially if we are using a VM."
"There is no licensing cost for the solution."
"The solution is moderately expensive."
"In terms of the cost, SQL Azure is a pay-per-use solution, particularly because it's a cloud subscription, so you pay as much as you use it."
"I have an annual spend number, and it is in the hundred thousand dollar range. There are no additional costs to the standard licensing fees. Even though you have to look at the cost numbers of what you're going to be charged on a monthly basis, what you have to also remember is that your application may need a lot of rewriting and things like that. You get charged not just for the monthly costs but also for the transactions that occur. If your access to the data layer is not so efficient, your costs will go up because you're pulling far more data than you potentially need. These are hidden costs that nobody ever considers. If your application is not written very efficiently, you may actually increase your costs over on-prem versus cloud."
