Multiple customers could access the same apps at the same time, a feat only mainframes could do. Starting in the 1990s, application service providers (ASPs) hosted applications on behalf of thei…

This is how Salesforce and every other SaaS operator runs. Every tenant is a customer/user who has common access and specific privileges in the software instance. The d…
