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.

Solutions Architect at a tech vendor with 10,001+ employees
Cloud database service has reduced admin workload and delivers reliable automated operations
There are no managed detection response solutions or backup and recovery and point detection response. Flash storage is not available as Flash Creek store. Robotics process automation and application security testing are not available; I went to the working solutions, but most of the time it did not work. Oracle Database as a Service in particular is the Oracle business suite or the Oracle data access. As far as working with it as a service, I have not even received a reply yet from the relational database service. I do not know how many people are using Oracle Database as a Service in my organization. For the diabetes service, I have used some of the perks from Arkin. I rate Oracle Database as a Service at a nine overall.
