That phrase became Sun Microsystems Inc.’s slogan, and that vision has become truer over time. And yet, why are huge hunks of software still installed on individual computers as though they were isolated lumps of hardware?
如果您在没有Internet连接的地方孤立，则可能需要在计算机上安装几个软件包。但是如今，这种情况很少发生，因为连接与手机服务一样无处不在。在企业层面，一切都是联网的。因此，具有传统最终用户许可协议（EULA）的软件包安装已过时。
Widely used operating systems such as Microsoft Windows require regular upgrades for improved security and bug fixes, and these typically arrive automatically via the network. When you’re online, have you noticed how your computer is commandeered suddenly by Windows, or by anti-virus or Java updates? If the user is not present when the update install-prompt arrives, the software takes over and does a self-install. On returning, the user finds that all open applications have been exited and the computer has been mysteriously re-booted. There is virtually no software that is immune from this dreaded update disease.
Virus-protection software such as Symantec or McAfee cannot be sold as one-install packages because protection must be updated constantly to protect against the latest virus dangers that arrive constantly. Indeed, when any licensed computer is booted up, it automatically keeps checking for updates.
安装软件通常要求用户每台计算机拥有完全付费的许可证。要在家中或在其他位置工作，远程许可证是没有用的。大型包装的安装过程可能很复杂且耗时。此外，移至新计算机涉及多个软件包安装，然后进行了更新和错误修复。包装软件的包装软件在多少计算机上仍处于休眠状态？
Software as a Service (SaaS, typically pronounced “sass”) is here, and it’s the wave of the future. SaaS is a software deployment model in which enterprise applications are delivered and managed as services to meet the needs of multiple customers simultaneously. Applications are licensed for use on demand, removing the cost and burden of installed software on every computer. This greatly reduces the ongoing maintenance required for conventional “full” installations, and facilitates central control of all updates and upgrades.

Suppliers establish an ongoing revenue stream using centralized control, offering flexibility without the complexity and high initial cost of equipping computers that may be used only occasionally. On-demand licensing makes usage a variable expense, typically far less than traditional up-front, per-user pricing. In addition, it reduces user investments in server hardware.
The distinction from complete applications delivered over the Internet is that SaaS solutions are developed specifically to leverage browsers, making them “Web-native.” The design and architecture of SaaS applications are specifically built to enable multiple users to access a shared-data model.
SaaS改变了安装的负担，并将应用程序从用户转移到供应商。用户可以在没有其他人员资源的情况下利用快速功能。企业客户从供应商的最新技术功能中受益，而没有与软件更新和升级相关的中断和成本。
SaaS providers leverage economies of scale in management and customer support through software development lifecycles. Saas-delivered software enables end-users to deploy automation more quickly, experience more predictable costs and achieve a faster return on investment (ROI). Studies have demonstrated ROI within in six months or less, typically two to four times faster than fully installed EULA alternatives.
Why go stale? Go SaaS!
