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 best thing about the solution is that it is tightly integrated with Azure Functions and Azure App Service, making it easy to deploy to the cloud."

"Great auto-scaling and security features."

"Hosting these types of databases on-premises can be challenging, but if you have the ability to do it on Azure, that is beneficial, and it also removes security obstacles as well."

"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 product's initial setup phase is very easy."

"The most valuable features of SQL Azure are its reliability and quick scalability."

"We've saved time setting up the databases. While I'm not involved in the maintenance, I'm sure that's also a big factor. It's hosted in the cloud, so we don't have to maintain the servers."

"Microsoft's expertise in SQL Server is a significant advantage."

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."

"They could improve Azure SQL by adding some of the features available on-prem, such as cross-database queries and the ability to run particular jobs. We need to migrate those to something else, like a function or logic app."

"We have a very small database running on SQL Azure. We have not been able to load bigger systems on it. It is still not something that is feasible. All our heavy-duty systems are on SAP, and it should have more compatibility with other vendors such as SAP. Its price can definitely be lower. It is pretty pricey."

"Lacking in technical documentation."

"The initial setup was very complex."

"The latency and availability of Microsoft Azure SQL Database can be problematic when connecting to an instance in a geographically distant location."

"One area for improvement is data virtualization. Companies use different data sources, creating a separate data virtualization layer, and there are more data sources behind that layer. For example, we have different data layers for Excel, SQL Server, PostgreSQL, etc. Creating a data virtualization layer would help because you retain the metadata of your source data."

"Lack of flexibility for developers in terms of performance assistance."

"Adding users to Azure SQL could be easier. You need to script it out, but it would be nice if it had a UI where you can click and add them. It's not a major thing because we script things all the time, but it would be a minor thing that helps us."

Pricing and Cost Advice

Information not available

"SQL Azure's licensing cost is expensive."

"It is beneficial in terms of cost because you are charged per data unit instead of licensing."

"The pricing is actually complicated, and that is probably one downside of it. In some respects, although we can plan for the costs on a month-by-month basis, we are finding it hard to project our costings for it. Fundamentally, Microsoft is offering two pricing models, and it is challenging to understand the differences between the two. We're basically on the DTU model at the moment. That may change in the future as the size grows, but it is one of those things that we'll end up monitoring as we progress. At the moment, to get a reasonable response, generally, the price is a little high for us, but it is one of those things for which we know that we can do improvements on our code. So, it is not just the service that's the problem; it is some of the things that we need to do as well."

"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."

"You can use it for smaller instances and pay less. You can also go for the premium product with all the security, scalability, and business continuity features, but you have to pay a premium amount."

"The price of the solution is reasonable."

"We have a three-year contract. The cost was somewhere around $70-80,000 for the original deployment, which was about two years ago"

"I believe the licensing is more on a global scale."
