SaaS providers build all the network infrastructure, software and hardware operating platforms needed for enterprise informatization, and are responsible for all services such as pre-implementation and post-maintenance. Enterprises can use information systems through the Internet without buying software and hardware, building computer rooms and recruiting IT personnel. Just as water can be used by turning on the tap, enterprises rent software services from SaaS providers according to actual needs.
SaaS is a software layout model, and its application is specially designed for network delivery, which is convenient for users to host, deploy and access through the Internet. The price of SaaS application software is usually a "all-inclusive" fee, including the usual application software license fee, software maintenance fee and technical support fee, which are uniformly included in the monthly rental fee of each user. For most small and medium-sized enterprises, SaaS is the best way to adopt advanced technology to implement informatization. However, SaaS is not only suitable for small and medium-sized enterprises, but also enterprises of all sizes can benefit from SaaS.
Before 2008, IDC classified SaaS into two categories: hosted AM (formerly called application service provision (ASP) and customized software on demand (synonymous with SaaS). Since 2009, managed application management has been a part of IDC's application outsourcing plan, and customized software and SaaS are regarded as the same delivery mode.
SaaS has become an important force in the software industry. As long as the quality and reputation of SaaS can continue to be confirmed, its charm will not fade.
