There are two types of scalability: vertical and horizontal. We scaled vertically so that ORUEI is more stable. If one is down and then another is up. So it is friendly to the concept of scalability. We're not using it very much, but Oracle has come out with a cloud solution. The product o called Oracle Management Cloud, OMC. OMC has similar features, but it can be deployed on the cloud and also on-prem. So we are thinking of using the OMC for the cloud, and for on-prem, we will still use ORUEI.

I would rate the scalability a nine out of 10. This rating is based on the fact that when customers provide the hardware and other necessary elements, there can be certain limitations. 

These limitations might prevent them from achieving the same level of product quality. However, if they consider enhancing the expandability of features and the quality of their service, it could potentially improve their rating. Currently, their score is around five, mainly due to certain limitations they've experienced over the past five years. This could be related to administrative changes or hybrid setups, but I'd say it's about a nine at the moment.

No issues.

In order to scale it up, you might have to understand the solution a bit more. We have about 250 people using the solution currently. We use it pretty extensively.
