Software as a Service. Refers to software which works under the model of the user paying to use the software instead of the traditional model of paying for owning the software (or owning a license for it). Typically SaaS is used for software packages which are run across the internet.
软件即服务。不同于传统的购买软件、或购买软件授权的模式,它倾向于用户付费使用软件,用软件提供商提供服务。典型的SaaS一般被用于互联网。
