SaaS, an abbreviated name for software-as-a-service, which means the provision of software services over a network, is a completely innovative software application model that is taking shape in the 21st century.
SaaS is a model of software delivery over the network, the vendor provides the application software uniformly on its own server, customers can order the required application software services from the vendor over the Internet according to their actual needs and pay the vendor according to the number of services ordered and the duration, and purchase the services provided by the vendor over the Internet.
Users no longer need to purchase software, but instead, take advantage of the opportunity to rent Web-based software from the Provider to manage their business activities and no longer need to maintain the software. The service provider will have full authority to manage and maintain the software, the software providers will provide Internet applications to customers, but will also take over the offline operation of the software and local data storage so that users can use their subscription software and services anytime, anywhere.
For many small businesses, SaaS is the best way to use advanced technology that eliminates the need to purchase, build, and maintain infrastructure and applications.
One of the earliest SaaS services was online e-mail, which dramatically lowered the threshold for individuals and businesses to use e-mail, changing the way people and businesses communicate. Services for individual users include editing documents online, creating forms, managing appointments, managing contacts, and more. Services for business users include online storage management, online conferencing, project management, CRM (Customer Relationship Management), ERP (Enterprise Resource Management), HRM (Human Resource Management), management of online advertising and application services for specific industries and sectors, etc.
