Multi-node architecture and it is good from a security point of view
I would rate the stability a seven out of ten. Most of the issues we faced during troubleshooting were due to specific bugs in the environment, and the only solution was to upgrade the database environment or services. But it is not easy to upgrade the database level when third-party applications are involved, as they are not always comfortable with upgrading. There should be some cumulative solution provided by IBM for their customers, just like other vendors. Upgrading to a certain version doesn't always resolve the issue. It might get resolved at the database level, but what about the other applications integrated with that database that are only compatible with older versions?

Automatic tuning and multi-region availability have reduced manual workloads and improved performance management
The features of Microsoft Azure SQL Database that I like the most are easy scaling and high availability. I appreciate those features because it's easy to make Microsoft Azure SQL Database readily available in a multi-region infrastructure. Using Microsoft Azure SQL Database is very easy; it's much easier than SQL on-premise because I don't have to worry about deploying infrastructure, and I can rapidly deploy via infrastructure as code. I am using the automatic tuning feature in Microsoft Azure SQL Database. We are using the new feature of data encryption in Microsoft Azure SQL Database with customer-managed keys only. The reliability and stability of Microsoft Azure SQL Database platform are rock-solid; it's as good, if not better, than what our on-premise stability has been from an uptime perspective.

Quotes from Members

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

Pros

"Multiple business departments rely on reports and predictive analysis to make decisions for future business based on their data warehouse and Db2 network analytics tool. It helps our business department make decisions."
"The reliability is the most valuable feature. It is also user-friendly."
"The feature I appreciate most about Microsoft Azure SQL Database is the ease of use; whenever we navigate to the portal, we realize that it is user-friendly and intuitive, and if there is a problem such as an application being down, we know exactly where to look and what to do to troubleshoot it quickly."
"The database is extremely scalable, allowing seamless scaling up or down with a simple change in parameters."
"The dashboard is valuable."
"This solution offers high availability, and business continuity is in place."
"Its cost benefit is most valuable because you are charged per data unit instead of licensing."
"What I found most valuable in Azure SQL are the functions related to Active Directory and the database services."
"The initial setup was straightforward. It took less than one day for deployment."
"Right now, with Azure, we have everything we need."
 

Cons

"I would give their support a ten if they had more tutorials available."
"In other environments like Oracle or Teradata, they provide their own solutions for troubleshooting issues. They provide built-in AI services or autonomous databases, which I don't see in the Db2 environment."
"Nobody is going to like the price."
"The preset configuration switches we can select on SQL Azure should be made more liberal to work on."
"The pricing plans when using multiple Microsoft solutions are complex and have room for improvement."
"Microsoft Azure SQL Database could improve by having better tooling in terms of connecting to other database platforms and better capabilities around programmable interfaces. There should be more fine-tuning on the storage layer. I would like to see T-SQL improvements to automatically translate features from other database platforms for easier migration, as well as some improvements around column store and native capabilities like those in Iceberg and PowerK built into the SQL Server product."
"They should also simplify the security in Azure. We are using the cloud as a platform, so there is no physical infrastructure. We're using Azure components like databases and servers to create an application. Integrating those components in terms of permissions and security is challenging for us. Maybe there is a lack of knowledge on our side, but it's not straightforward."
"We've had many concurrency issues with it, particularly with applications that do a lot of parallel processing. We noticed that sometimes the Azure SQL databases would spike and peak their CPU units, causing some performance issues for us. It would be helpful if CPU performance were not pinned to the amount of storage you're using, and we could scale different properties of the Azure SQL database independently."
"It should have better profiling capabilities."
"The user interface (UI) could be more flexible."
"There are some limitations for cross-database queries and features. The migration of data from older systems should be easier. For deployment, there are too many options, which sometimes makes it difficult to figure out the best option. There is not enough information to help you to find the best option for deployment. There should be more documentation about this."
 

Pricing and Cost Advice

Information not available
"It is beneficial in terms of cost because you are charged per data unit instead of licensing."
"We pay less than $1000 monthly in licensing fees. There are no additional costs."
"The solution is more cost-effective than Google BigQuery. Compared to Google BigQuery, downloading data can be more expensive."
"It only has a subscription-based license."
"It is quite expensive. I would definitely recommend not using the pay-as-you-go model because this will just mean all your money will go to Microsoft. So, really make sure to control resource usage as much as possible."
"The price could be slightly cheaper."
"SQL Azure is an expensive solution."
"We have had some issues with the licensing of the solution."
