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?

It is very easy to implement, manage, and offers great insights into what is happening inside the engine

Microsoft Azure SQL Database is integrated into other Azure capabilities and has a great foundation being on SQL Server with a long history of security, performance, and usability from a DBA perspective. Once you've set up a server, adding databases is easy. There's a minor challenge with having data in separate databases that you want to connect like we do on premises. I'm looking forward to using some of these new AI-driven functions that have come out around vectorization. Having the data closer to my transactional databases or data makes it easy to augment and enhance the Database and applications I currently use. It's great that Azure SQL now seamlessly integrates with Microsoft Fabric. It's a first-tier service in the cloud that connects to web applications and other databases. The data transformation orchestration capabilities within Database Factory and similar capabilities make it effortless to move that stuff forward.

Quotes from Members

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

Pros

"The reliability is the most valuable feature. It is also user-friendly."

"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."

"We have used SQL for a long time. Azure SQL has helped teams across the organization to use SQL's full potential. I can't say what the cost savings were precisely, but I believe it has reduced the total cost of ownership."

"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 scalability and simple management of the infrastructure are the most valuable features."

"I rate Microsoft Azure SQL Database 10 out of 10."

"The automated scalability feature of SQL Azure has proven to be highly beneficial, particularly when deployed in the cloud."

"Its cost benefit is most valuable because you are charged per data unit instead of licensing. You can easily migrate your on-premise SQL to the cloud with a managed instance. That's what it is designed to do. It is easy to take your on-premise or older SQL instance and move it to the cloud. It makes it easy to get off your on-premise SQL and start utilizing the cost benefit of the cloud."

"The initial setup was straightforward. We did not migrate from an existing system but implemented it from scratch and did not require Microsoft support. We were building Power Platform apps using SharePoint databases and Excel. And after that, we realized that we had to integrate it with SQL. It wasn't too hard, and our partners have people with experience."

"My main use case for SQL Azure is for a self-reading application related to portfolio management. In this application, users can have portfolios designed and managed based on recommendations from their brokers. These recommendations are sent to users, and if consumed, they get executed and added to their portfolios, which can be easily maintained through mobile applications. This involves using Kafka for messaging and execution."

More Microsoft Azure SQL Database pros

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."

"I think this product can improve its integrations with business intelligence software. The integrations are always cumbersome due to the approvals, passwords, et cetera."

"Microsoft Azure SQL Database could improve by having better tooling in terms of connecting to other database platforms and better capabilities around programmable interfaces."

"The managed SQL MI does not allow us to control the zone it runs in, which affects latency."

"If there are areas for improvement, one aspect could be the user interface. It could be made more user-friendly and similar to Google BigQuery's interface."

"We've noticed an unexpected increase in the cost of running the server over the past few months."

"Improvement could be made in the performance tools, offering a better overview of core issues like process activity and latency, as we currently rely on third-party tools and SQL jobs for monitoring and alerts. A comprehensive built-in solution for performance analysis would be beneficial."

"Azure SQL had a bit of a learning curve to start, but it was fairly simple once I understood how to develop it. I was using PowerShell to connect to it, and I've never connected to online databases through Azure using PowerShell. Scripting the PowerShell connections could be simpler. The coding is familiar, but figuring out how to use it initially can be easier."

"Azure SQL had a bit of a learning curve to start, but it was fairly simple once I understood how to develop it."

Pricing and Cost Advice

Information not available

"The price in general of Azure SQL could improve."

"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."

"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."

"With one being expensive and five being competitive, I would give the product a four out of five as it's relatively competitive. It is also important to note that pricing is based on usage."

"I recommend considering a pay-as-you-go pricing model initially."

"When you go with SQL Azure Database, you can create a small database, which is around $4 to $5 per month for development purposes."

"It's reasonably priced and when you compare it with other products in the cloud environment, it's cheaper."

"I find that they are relatively expensive, especially when compared to AWS, where the prices are notably lower."
