Answer 
Companies used various methods before cloud computing, primarily relying on on-premises infrastructure:

Client-server architecture: Centralized servers provided resources to individual client devices on the local network.

2)Dedicated hosting: Companies rented dedicated physical servers from hosting providers but still managed the software and maintenance themselves.
