Web应用程序，SAAS？ [英] Web application, SAAS?

问题描述

我想试试undestand真正的SAAS是什么。它是软件即服务，而hotmail的展望是SAAS的一个例子。但我仍然困惑。
假设，我建立了一个网络应用程序医院管理系统，它保留所有病人的记录，所有这一切，它是一个软件即服务。什么具体的东西需要是一个软件即服务，或只是一个Web应用程序是SAAS ???

I am trying to undestand "What really SAAS is". It is Software as a Service, and hotmail outlook is one example of SAAS. But I am still in confusion. Suppose, I built an web app "Hospital Management System" which keeps the record of all patient and all that, Is it a Software as a Service. What specific things are needed to be a Software as a Service, or just a web app is a SAAS????

推荐答案

软件是部署和管理的SAAS，用于为同一部署中的多个用户。这意味着软件不是在客户端部署，并且不需要每个租户一个。

A software is SAAS if it is deployed and managed to serve mutiple users (tenant is the term here) from the same deployment. That means the software is not deployed at the client side and it need not be one per tenant.

如果您将您的医院管理系统部署在您的基础设施中，您的医院管理系统将是一个SAAS和多家医院使用它们，就像你为每个人创建一个。

Your Hospital Management Systems would be a SAAS if you deployed it in your infrastructure and multiple hospitals used them as if you had created one for each of them.
