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.

Positive experience with virtual cloud network creation and database migration highlights patching challenges

The best feature of Oracle Exadata Cloud at Customer is that it can be managed without needing only DBAs. We have many features, including the observability feature that helps check performance and generates numerous reports about performance. We have also implemented APIs, enabling us to create and perform many operations. This means we need DBAs who can work with APIs. We are autonomous in the patching process and don't need Oracle for patching. If you configure the process of patching, it will be executed automatically. We are using dynamic scaling which is implemented on an external virtual machine, helping us to downscale or upscale the CPU. Oracle Exadata Cloud at Customer has supported our organization's compliance and data sovereignty without problems. I have observed some limitations. For example, regarding encryption, though it is mandatory for Exadata Cloud at Customer, we cannot encrypt the database with external keys. Currently, with Exadata Cloud at Customer, using external keys is not possible.

"We can scale the solution if we need to."

"It is a very scalable solution."
