It's a very scalable tool because it allows those working on it to work with clusters, especially if we discuss PingFederate's horizontal scalability. One can use any number of nodes needed, but usually, two or three nodes are enough during the production phase. For how the solution has been set up and programmed, I rate the solution's scalability a nine out of ten. Owing to an NDA that my company has signed, I can't disclose the exact number of my company's customers who use the solution, but I can say that many use the solution, and it goes more than 50 in number.
