虽然SaaS的一些特性在科学领域，特别是在科学网关领域已经被利用了很长时间，但SaaS模型还没有被广泛采用。例如，很少有科学SaaS提供商是公开可用的，很少有利用弹性云平台的，除了Globus之外，没有一个实现基于订阅的模型来收回运营成本。Globus采用SaaS模式已经7年了，并且正在快速接近支持长期可持续性的订阅水平。本文讨论了SaaS范式，并探讨了其在科学领域的适用性。然后，我们将描述如何实现、部署和操作生产Globus SaaS服务。
While some properties of SaaS have long been leveraged in science, particularly in science gateways, there is yet to be widespread adoption of SaaS models. For example, few scientific SaaS providers are publicly available, few leverage elastic cloud platforms, and none--with the exception of Globus--implement subscription-based models to recoup operations costs. Globus has employed the SaaS model for 7 years and is fast approaching subscription levels that will support long-term sustainability. In this paper we discuss the SaaS paradigm and explore its suitability to scientific domains. We then describe how production Globus SaaS services are implemented, deployed, and operated.
