IAS servers can accommodate a large volume of accounts and authentications per second. For this reason, they perform well in large organizations. A single IAS server can often meet the dial-up and VPN connection needs for an entire network. However, if you have more complex network access needs, you might need to scale even a single IAS server. For example, certificate-based authentication can generate a large volume of authentication traffic that is transmitted every time a client logs onto the network. If you use certificate-based authentication, you must scale IAS to meet all of your Internet authentication needs.
