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."
"Microsoft Azure SQL Database has significantly reduced our total cost of ownership by eliminating the need for a dedicated environment to host SQL."
"The most valuable aspect of Microsoft Azure SQL Database is its accessibility."
"SQL is a simpler database. We use it more than other databases."
"The solution effectively handles storing and maintaining information in databases."
"The automated scalability feature of SQL Azure has proven to be highly beneficial, particularly when deployed in the cloud."
"Microsoft Azure SQL Database supplies reliability and efficiency with its infrastructure, which is very beneficial to our organization."
"I rate Microsoft Azure SQL Database 10 out of 10."
"The most valuable feature is PolyBase."
More Microsoft Azure SQL Database pros
 

Cons

"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."
"I would give their support a ten if they had more tutorials available."
"The pricing is very high."
"Integration needs to be improved for this solution."
"The only thing that concerns me today is the pricing connected with Microsoft Azure SQL Database; everything else is all right."
"I would like to the solutions scalability to be improved."
"What would make SQL Azure better is users having the capability of managing the database solution from the cloud, instead of having to do it from an actual machine because currently, database management via SQL Azure is done on a virtual machine or a PC. The solution should have the data functionality of managing SQL databases inside the cloud."
"Some more documentation and suggestions for network policies could be helpful."
"One area for improvement could be expanding the search queries using vectors or AI inside the database."
"It's a little bit limited in terms of functionality."

Pricing and Cost Advice

Information not available
"If we use a smaller or free-sized Microsoft Azure SQL Database, it is extremely cost-effective and much cheaper than on-premise enterprise licenses, which are expensive."
"When looking at the long-term expenses associated with running software on an on-premises server, the costs are almost equivalent but when we include insurance for devices, onsite fees for servers, and other related costs, we may find that this is a cost-effective solution."
"I find that they are relatively expensive, especially when compared to AWS, where the prices are notably lower."
"We have the licensing fee, and we are also paying a third party to maintain it with an SLA. There is no infrastructure cost, but its running costs are higher than expected. There is the cost of the Azure cloud, which is pricier than expected, but it is not specific to SQL Azure. It is specific to the cloud. You expect it to be cheaper, but it is more expensive to run it."
"I am not aware of the exact pricing, but our monthly bill for Azure is around 80,000. It is less expensive than using SQL Server. It has the pay-as-you-go model, and the charges are based on the usage."
"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."
"We have a three-year contract. The cost was somewhere around $70-80,000 for the original deployment, which was about two years ago"
"It requires a license. As compared to its competitors, such as Oracle, it is affordable and reasonable."
