Ethan Lo - PeerSpot reviewer
Infrastructuer Security at Premise Data
A stable and scalable relational database that ensures a return on investment for its users
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. You can change Google Cloud Spanner's resource configuration, which is done through processing units. Suppose you set up Google Cloud Spanner initially with a hundred processing units, and then you run out of resources since your database used too much CPU. In the aforementioned scenario, you can scale up or down and face no downtime in the production phase. The solution's features are important when running a company twenty-four hours, seven days a week.

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.

Pros

"Google Cloud Spanner is stable."
"We can scale the solution if we need to."
"It is a very scalable solution."
"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."
"The application deployment in the cloud is the best feature of the infrastructure."
"In my current role, I consider SQL Azure the leader for cloud-based RDBMS solutions, far ahead of any other cloud-based RBMS offering."
"Customers can benefit from a lot of cost savings if they go for Azure."
"Microsoft Azure SQL Database scales well, allowing us to increase our compute level or add more instances as required."
"Its cost benefit is most valuable because you are charged per data unit instead of licensing."
"The stability is good."
"The management and the remote access in SQL Azure are seamless."
"I rate Microsoft Azure SQL Database 10 out of 10."
"Your return on investment from SQL Azure would depend on your business applications. The solution will give you more scalability, and more functionality, and would reduce costs from on-premises to cloud databases, so there are a lot of cost reductions."
 

Cons

"The cost can be a bit high."
"The tool needs to improve horizontal scaling."
"The tool lacks to offer AI features."
"I want to improve the deployment of cameras and surveillance infrastructure."
"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."
"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."
"Microsoft Azure SQL Database is one of those solutions that helps consolidate our infrastructure, though unfortunately it is not the only solution we use."
"It does take some time to learn about the environment."
"I was using a user list for connecting a program in OTF for getting information. The connection in SQL Azure can improve by being easier because at the moment I have to use private certificates for user authentication. I had to do additional configuration to have the connections."
"Their support is nice but frequently their responses aren't effective."
"Microsoft Azure SQL Database could be improved by offering an easier way to view all existing roles in the database without needing complex queries found online."
"I would like to see integration with Snowflake."
