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

"It is a very scalable solution."
"We can scale the solution if we need to."
"Google Cloud Spanner is stable."
"The solution is stable and reliable."
"The application deployment in the cloud is the best feature of the infrastructure."
"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 easily scalable, and it is faster than SQL Server. It is also less expensive than using SQL Server. It has the pay-as-you-go model, and the charges are based on the usage."
"The most valuable aspect of Microsoft Azure SQL Database is its accessibility."
"The product is quite stable. The performance is great and it's reliable."
"Microsoft technical support is good."
"The most valuable features of SQL Azure are its reliability and quick scalability."
"The main advantage of it is that there is no infrastructure cost; we don't have to host it here, and we can grow it or shrink it depending on the demand with no restraint on capacity."
"Coding does not require much effort."
"It's a good cloud solution, very easy to use on any platform and works well."
 

Cons

"I want to improve the deployment of cameras and surveillance infrastructure."
"The tool needs to improve horizontal scaling."
"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."
"The tool lacks to offer AI features."
"I think Microsoft Azure SQL Database should be cheaper. The license is expensive, but not always; it depends on the case regarding pricing and licensing."
"For simple queries, it usually goes smoothly, but more complex issues tend to lead to tough discussions and often require escalation to our Microsoft contact due to slower response times."
"My only concern regarding the pricing, setup cost, and licensing of Microsoft Azure SQL Database is that we have a large database size but limited compute requirements, which has forced us to move towards a higher core just to meet our database sizing requirements."
"We've had many concurrency issues with it, particularly with applications that do a lot of parallel processing."
"Certain features available commercially may not be applicable in our gov cloud."
"One area for improvement is setting up logs, especially for servers like VM SQL. It was also tricky to connect services on VNets to on-premise."
"The user interface (UI) could be more flexible."
"Price definitely will be the negative point. It is quite expensive."
 

Pricing and Cost Advice

"Google Cloud Spanner is an expensive solution."
"It is expensive."
"The solution is expensive."
"Price-wise, I heard that Google Cloud Spanner is on the higher side."
"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."
"When you go with SQL Azure Database, you can create a small database, which is around $4 to $5 per month for development purposes."
"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."
"It is expensive for us. We are looking for something less expensive and thinking of migrating the whole system."
"Microsoft services are costly, which is the only problem we face. So, pricing is an area of improvement."
"The price could be slightly cheaper."
"We have had some issues with the licensing of the solution."
"Its price can definitely be lower. It is pretty pricey."
