Multitenant is very scalable for the paid version. The free version is limited to three pluggable databases. If your requirements are greater than that, you'll need the paid version and then you can get thousands of databases, so it's very scalable. The extra resources required to add databases are very small. 

I rate Oracle Multitenant nine out of 10 for scalability. It can be complicated to scale up the solution, but it's scalable. We have 35,000 users. 

I would rate the scalability of Oracle Multitenant as a ten out of ten. We have approximately 15 users at our company.

It's really scalable. The licensing is easy. As you continue having more workloads, you continue to license for more calls. It moves up with you.

We are a bank and we have many, many users. 

We have had no issues with scalaing it.

I compared the performance of a CDB with 10 PDBS with 10 distinct databases, and the Multitenant databases in total run much faster.

We are all stand-alone right now. We are not interact, so I'm hoping, with the kind of product Oracle comes up with, that it will definitely be scalable.

There have been no issues scaling it for our needs.

I feel that it is a scalable solution, but we have not reached that stage where we will start choking on the capacity. We have not reached that 255 in one, single container database, but I hope it will not choke. We have not reached that stage yet where we are reaching that limit.

Scalability of Multitenant architecture comes with the Multitenant option. You need Enterprise Edition plus Multitenant in order to have multiple pluggable databases managed by the same instance. Without the option, and in Standard Edition, you can create at most one pluggable database in a container database (CDB).

This solution is scalable.

This solution is scalable.

This is a good product for consolidation purposes.

Release 12.2 has really improved on scalability. If you put 250 pluggable databases on one machine and the resource manager isn't up to par, you can't really move it around much.
