Offers good performance to users
The tool lacks to offer AI features. In the future, I would like the product to offer AI features to users. Nowadays, we are creating small acronyms for our SQL Server. We put some templates. If I just put your name and stop it, the entire cloud can be explored, but such features are not there in Google Cloud Spanner. As a layman rather than a developer, if I create a tool or a procedure. If I write a procedure and then when you describe a procedure, a dummy procedure will be written for you, and it will be available for you as a template in SQL Server, but such kind features are not there in Google Cloud Spanner.

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

"The most valuable feature of the solution is its scalability. Scalability comes with two options, among which Google Cloud Spanner can scale horizontally, compared to other relational databases that scale vertically."
"The solution is stable and reliable."
"We can scale the solution if we need to."
"It is a very scalable solution."
"Google Cloud Spanner is stable."
"The application deployment in the cloud is the best feature of the infrastructure."
"The effectiveness of Microsoft Azure SQL Database security features in meeting our compliance standards is crucial because we are SEC compliant, and that is one of our main criteria for compliance; otherwise, our investors would be very upset."
"It is easy to scale in Azure in a way that I cannot scale on-prem."
"The most valuable aspect of SQL Azure is the SQL language itself. It's open and everybody can use it at my company. Also, we thought in the beginning that the response time would be inadequate, but it's actually decent. It's much better than expected. Then again, I'm not a programmer, but that's what I hear from our development team."
"Our migration to Azure for most databases has increased our organization's efficiency and reduced the maintenance required to manage on-premises infrastructure."
"The scalability is good, as we have 100 users and one can upgrade the system by performance and by the size of the storage, moving between different types of storage using block or docket in any way you choose without losing data, so the scalability is very good and we plan to increase our usage."
"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."
"I like that Microsoft Azure SQL Database is almost identical to an on-premise SQL Server except for a few things, like how you edit rows and some jobs that you can't run."
"The interface is awesome."
 

Cons

"The tool needs to improve horizontal scaling."
"The tool lacks to offer AI features."
"Google came up with something called Cloud Spanner Emulator, which fails to work like the real product if I want to develop some code and run a database locally on my machine."
"The cost can be a bit high."
"I want to improve the deployment of cameras and surveillance infrastructure."
"The way it has been designed, in the on-premises deployments, the underlying Windows OS is highly scalable but has a very large resource requirement. A lot of power-related and memory-related things are there, which I have not seen in the RHEL and Oracle. I have not tried SQL on RHEL EXEC. On Windows, infrastructure-wise, a very large workload is running on the SQL. This issue is related to Windows, not SQL."
"SQL Azure's performance monitoring features need to be improved. It has a pricing calculator, but it would be great if we could get a rough estimate of the pricing based on fewer parameters, like the data size and the scale of the company."
"The solution lacks feedback tools."
"Microsoft Azure SQL Database could improve by providing more support for Availability Groups within Managed Instance."
"I think that the cost management in SQL is not clear because we may use some tax to identify products, but in some cases identifying the transactions in SQL is not easy for some financial cost centers."
"The solution could improve by allowing the export of the data more seamlessly. It is difficult to copy and back up data."
"Azure SQL can improve by adding more machine learning features like other databases, such as Cassandra or Cosmos DB."
"It's a little bit limited in terms of functionality."
 

Pricing and Cost Advice

"The solution is expensive."
"It is expensive."
"Google Cloud Spanner is an expensive solution."
"Price-wise, I heard that Google Cloud Spanner is on the higher side."
"SQL Azure is an expensive solution."
"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 would rate the pricing a seven out of ten."
"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."
"We have a three-year contract. The cost was somewhere around $70-80,000 for the original deployment, which was about two years ago"
"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."
"Microsoft services are costly, which is the only problem we face. So, pricing is an area of improvement."
