Common SaaS practices
How to commercialize existing applications as SaaS?
In order to reduce or even disappear, some vendors use virtualization technology to deploy all software on the Enterprise Server. Employees only need to log on to the domain of the enterprise, the OS-level virtual mechanism is automatically enabled. If you select the software that runs the virtual desktop, the software will be immediately sent from the server, cached locally, and started for execution, turn desktop software into SaaS immediately.
The idea of using virtualization technology to turn software into SAAS is similar to "VOD, video on demand". You can call it "sod, software on demand) or select an application (AOD, application on demand ). At present, large enterprises have adopted this technology internally to work everywhere (without a fixed seat). ISP providers are also using this platform, prepare to provide software rental services to its customers (the software is regarded as a service and is billed on time ).
The SAAs approach of SOD is similar in technology and concept to diskless node, which is quite different from thin client. However, SOD is not the same as diskless workstation. Everything (including OS) on the diskless workstation is sent from the server and the software is executed on the client; the rule of SOD is that only the application software is sent to the client.
SAAS Using SOD has the following obvious advantages:
However, SOD still has disadvantages:
No matter which method is used, the biggest benefit of SAAS is to simplify the deployment and maintenance of software and reduce the human needs of the MIS department, which is the most attractive part of SAAS.
Many vendors such as Google and IBM are implementing SaaS, and the network infrastructure has been fully built. In the next few years, more and more software will exist in the form of SAAS.
