Driven by the profound potential of the public cloud and the associated complexity in using it, CloudBank serves as an integrated service provider to the research community through a comprehensive set of user-facing and business operations functions. These services span the spectrum from novice to advanced cloud users, including front line user support, cloud solution consulting, training, and assistance in preparing proposals that include cloud resources. CloudBank provides innovative financial engineering options that will give researchers more flexible cloud terms tailored for their needs and contribute to the sustainability of CloudBank operations. CloudBank helps NSF by bundling multiple small requests that come directly to NSF into a bulk request to cloud providers, dis-incentivizing more costly direct connections. Through this aggregation and innovative financial contract types, CloudBank passes along savings to researchers that would otherwise be unavailable to them.
