Software-as-a-service (SaaS) application generation and deployment supporting method and device

The invention relates to a software-as-a-service (SaaS) application generation and deployment supporting method and an SaaS application generation and deployment supporting device, which aim to solve the problems of the conventional SaaS software generation and release. The method comprises the following steps that: A, an independent software vendor obtains a development license of an SaaS application generation and deployment device by registration to become an official development user; B, the independent software vendor downloads a generation and testing tool kit by an independent software vendor (ISV) portlet, and integrates the tool kit into a local generation environment to make the local generation environment become an SaaS application description generation device for rapidly generating SaaS application; C, the independent software vendor performs application generation by utilizing the SaaS application description generation device, and uploads the description of the application into an SaaS application deployment device; D, the SaaS application deployment device adds bottom-layer realization to the application generated by the ISV to deploy the application into the SaaS application supporting multiple tenants and personalized customization; and E, the tenants try on, rent and customize the SaaS application.
