The solution is highly scalable so I rate scalability a ten out of ten.

I would rate the scalability a nine out of ten. There are some areas where improvements can be made from both the Oracle side and our end as well.

The solution is scalable so I rate scalability an eight out of ten. 

Scalability is a problem with any middleware platform that is built on virtual machines. OSB is horizontally scalable. I would like to see more containers there so that you don't need to depend on your infrastructure teams to spin up servers and install the operating systems and other things. Currently, you can't just spin up things or scale on the fly because they are hosted on regular VMs versus the containers. On the SOA side of things, there is a limitation on how you can vertically scale them because of the way it maintains the state. Because of that limitation, you cannot scale them vertically. You have to scale them horizontally. Because it maintains the state, depending on the type of integration, it needs a lot of memory for JVM, etc. 

The scalability of Fusion Middleware depends on the expertise needed for specific applications. If there is someone who knows about all the applications, then just one person can handle everything. So, the scalability varies based on the expertise needed for the specific applications you are using. I would rate the scalability of the solution as a nine out of ten. We have almost 1,000 users at our company. The usage frequency of this solution varies. It is not in constant use but rather follows a schedule. Typically, it is utilized every two months, with specific tasks and activities assigned to different individuals during those periods. We plan to increase the usage in the future.

I rate the scalability an eight out of ten. About 25 people in the organization use the solution.

It is indeed scalable. 

We have no problem with scalability. We use Oracle Identity Management at one of the largest companies in telecommunications. We have 500 private systems in the product. We have no problem with scalability at this point with 40,000 users.

We have six people for its operation. For development, we use Accenture and four or five dedicated people. There are six more people required for the operation of OIM in the company.

The scalability is good.

There are more than 100 people using this solution and we do not have plans to increase usage.

It is scalable. 

Minor issues.
