Second, SaaS overview

Basic concepts of 1 and SaaS

SaaS(software-as-s-service) means software as a service, and SeaS's Chinese name is soft camp or software operation. SaaS is a software application mode that provides software services based on the Internet. SaaS, as an innovative software application mode that started in the 2nd/kloc-0th century, is the latest trend of software technology development.

2. Comparison between 2.SaaS software and traditional software

Compared with traditional software, Seas software has advantages in the following three aspects:

(1) Low implementation threshold: In the traditional mode, many enterprises, especially small and medium-sized enterprises, are often discouraged by the threshold that software needs to pay high fees at one time, and it is difficult for customers to manage and maintain their own software in the traditional software mode.

(2) Pay on demand: According to Murphy's Law, under normal circumstances, 95% of functions only take 5% of the time. In the traditional mode, enterprises have to pay the full cost for functions that can only use 5%.

(3) Low risk: if the application of the software cannot meet the needs and goals of the enterprise after one-time investment. If the enterprise wants to replace a new software service provider, it will undoubtedly make the one-time investment in licensing fees go down the drain.

According to IDG's prediction, in 2009, 10% ERP software will be transformed into pure SaaS, and with the hot discussion of many media, it seems that the era of SaaS ERP is coming soon. But at the same time, there is a dark cloud over SaaS. It is a worrying security problem of SaaS ERP, and it is also the first hurdle that SaaS ERP selection must face.
