SaaS is Software-as-a-service (software as a service). SaaS providers build all network infrastructure and software and hardware operation platforms required for informatization for enterprises, and are responsible for a series of services such as all pre-implementation and post-maintenance. Enterprises do not need to purchase software and hardware, build computer rooms, and recruit IT personnel. The information system can be used via the Internet. Just like opening a tap to get water, companies rent software services from SaaS providers based on actual needs.
SaaS is a software layout model whose applications are designed for network delivery, allowing users to host, deploy, and access over the Internet. The price of SaaS application software is usually an "all-inclusive" fee, which includes the usual application software license fee, software maintenance fee and technical support fee, which is unified into a monthly rental fee for each user.
For the majority of small and medium-sized enterprises, SaaS is the best way to use advanced technology to implement informatization. But SaaS is by no means just for small and medium businesses. Businesses of all sizes can profit from SaaS.
Before 2008, IDC divided SaaS into two component categories: hosted application management (hosted AM), formerly known as application service provisioning (ASP), and "on-demand software," synonymous with SaaS. Managed application management has been part of IDC's application outsourcing program since 2009, while on-demand software and SaaS are treated as the same delivery model.
The SaaS service model is very different from the traditional licensing model software, and it is the development trend of future management software. Compared with traditional service methods, SaaS has many unique characteristics: SaaS not only reduces or cancels traditional software licensing fees, but also manufacturers deploy application software on a unified server, eliminating the need for end-user server hardware and network security equipment. And software upgrade and maintenance expenses, customers can get the software and services they need through the Internet without other IT investments other than personal computers and Internet connections. In addition, a large number of new technologies, such as Web Services, provide simpler, more flexible, and more practical SaaS.
One of the earliest SaaS services is online e-mail, which greatly lowered the threshold for individuals and businesses to use e-mail, thus changing the way of communication between people and between businesses. Up to now, the types and products of SaaS services have been very rich. Services for individual users include: online
document
editing , form making, schedule management,
contact
management, etc.; services for enterprise users include: online storage management, online conferences , project management,

question
From an industrial point of view, the hardware, software and the entire industry chain of the market in the previous SaaS industry were integrated, which also led to the overwhelm of SaaS in the entire industry chain. A SaaS enterprise needs to do hardware, software, platform, application, Looking for markets, customers, and sales, the industry chain is too long, which is beyond the ability of an enterprise, and because it is self-sufficient, its platform utilization rate is extremely low.

Cloud computing is to directly peel off the application, leaving the platform, and the platform is always the platform, while the cloud computing resources people concentrate on their own scheduling and services. In this way, people who do SaaS can focus on the business they are familiar with and provide others with the application of software and services.
把应用和资源两者剥离开之后，SaaS企业就能够找到自己的生存空间了，在这样的产业模式下生产电车的企业就不用考虑如何发电的事了，他们有更多时间造出更好的电车。
