I would rate the stability a nine out of ten. 

Stability-wise, Oracle Exadata Express Cloud Service is more of a seven out of ten. For example, when you have a requirement related to the solution's performance, you must contact the provider to request specific changes. It's similar to every other application.

The solution is very stable. We have customers who are running their mission-critical applications on Oracle Cloud, OCI Cloud, or Oracle Cloud Infrastructure with PaaS. Additionally, we have customers who are running their core ERP application on the SaaS. It is very stable and Cisco is committed to the service availability. The is one of the biggest things as compared to any other vendor. We have not faced a major problem, any downtime, customer losing data, or any similar situation.

I have no complaints about the solution's stability. But that depends on which database I use. I have other databases in projects and databases on very high container databases. People who have all the information from smartphones and events are placed in the databases one by one when they are looking and doing some business actions. These are very fast databases. These are not relational databases anymore. These are real containers.

I rate the tool’s stability an eight out of ten. There are some misconceptions regarding maintenance. I have never set up an infrastructure with zero downtime. Oracle must provide an infrastructure that has no downtime.

The product is highly stable. I rate its stability a nine out of ten.

The solution is very stable.

Exadata is a highly stable and mature solution.
