The difference between traditional software and saas

Generally speaking, the traditional software is to write the whole project and deliver it to the customer, and the server, code and other technology-related things are deployed and delivered to the customer in a unified way. In this case, the customer may need some technicians to help him run and maintain, and saas means that the customer customizes his own products from saas providers. The technology-related things don't need to be understood, just need to be responsible for the customer's own business and services, and saas providers are responsible for the technology-related things such as servers and operation and maintenance.
