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."
"It is a very scalable solution."
"The application deployment in the cloud is the best feature of the infrastructure."
"We can scale the solution if we need to."
"Google Cloud Spanner is stable."
"The solution is stable and reliable."
"SQL Azure is reliable and scales well."
"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 reason we moved to the cloud was for the convenience of not having any physical hardware to maintain."
"We've cut costs by around 70 percent."
"It's easy to work with large amounts of data, query it, and bring it back to a visualization tool to show it to the end users."
"The initial setup is straightforward."
"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."
"I prefer using Microsoft SQL Server because I like the experience and the way Microsoft handles the query tuning and security."
 

Cons

"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 tool lacks to offer AI features."
"The tool needs to improve horizontal scaling."
"Lacking in technical documentation."
"SQL Azure could improve the feature set. They are catching up to Microsoft SQL Server."
"The pricing is very high."
"I need Microsoft to allow their network to access open source technologies."
"The document storage is primarily relational, which is not ideally suited for SQL. If there were better integration with SharePoint for document handling in SQL, it would greatly benefit the organization. Moreover, the current on-premise limitations prevent direct file pulling, limiting certain capabilities."
"The pricing plans when using multiple Microsoft solutions are complex and have room for improvement."
"Its compatibility with existing applications can be improved. Its compatibility is currently a little bit imbalanced."
"SQL Azure could improve by adding more features."
 

Pricing and Cost Advice

"The solution is expensive."
"Price-wise, I heard that Google Cloud Spanner is on the higher side."
"It is expensive."
"Google Cloud Spanner is an expensive solution."
"The price in general of Azure SQL could improve."
"It's reasonably priced and when you compare it with other products in the cloud environment, it's cheaper."
"SQL Azure's licensing cost is expensive."
"Compared to other providers, the pricing is definitely on the affordable side."
"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."
"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."
"Offers options for paying the license on a yearly or a monthly basis."
"It is expensive. Snowflake and PostgreSQL are cheaper than this. Google is also cheaper than Azure. Its licensing is on a pay-as-you-go basis. It is based on usage and storage."
