ADSelfService is highly scalable.

It's scalable. There are many deployment options. If you want the on-premise option, you have that. If you want the cloud option, you have that option too. It's pretty good in terms of scalability.

I have installed this product on an EC2 instance. It's basically in the cloud. It's not on-premises because the server is in the cloud. It's an EC2 instance.

Scalability-wise, I don't think that there are going to be any issues with it. We keep hiring and pushing it out to more and more people. We'll never hit the 10,000 user mark so we don't know about that kind of scale but for our 500 or so users, it has not been an issue.

As the solution is user self-registration, it scales up as fast as the users are ready. So I would say it's very scalable.

There is no room for scaling. It's only dedicated to a simple task to handle the request for the active director account, mail account, and unlock. We have about 6,000 users now. We are establishing new sites and plan to reach 10,000 users next year.

The solution is generally very stable but we do get some errors and time delays that require uploading the login again which is frustrating.
