From an IT perspective, you no longer need to own and operate your own hardware and software assets. This removes the need for maintenance and updates, and either reduce or remove the need for a full-time IT assistant. A cloud service provider is a 3rd-party who hosts your software on remote servers where they provide the infrastructure to store and process your data. With SaaS, you no longer need to maintain the physical servers or the cloud-based software application, instead you pay a subscription for access to an already developed software application via a web browser which host information on a cloud.
