AC Solutions

Software as a Service (SaaS) is a model of cloud computing based on the distribution of software where an application is stored and made available to the users by its producer over the Internet. This eliminates the need to install software and activate it on the client’s computer. The SaaS model transfers the duty of administration, update, and technical servicing from the consumer to the vendor. As a result, the user cedes the control over the software and the duty to provide the continuity of its operation to the supplier.
