Cloud computing enables enterprises to access professional IT services without having to setup a professional IT production environment (data center) first. Especially in times of digital transformation, this could be a big chance for smaller enterprises which usually are challenged in accessing professional IT services. Theoretically, cloud computing seems to put professional IT service within reach of these enterprises. Additionally, advances in cryptography seem to sweep aside common security and privacy concerns. This paper argues that, on the current level of cloud computing and even assuming advances in cryptography, small enterprises in general will fail to seize this opportunity, making it more difficult for them to take part in the process of digital transformation. We propose a way for addressing this problem by providing automated cloud brokerage on SaaS level for smaller enterprises based upon sector specific IT architectures with variation points, thus making IT architectures and complete system environments accessible from the cloud and providing cloud brokerage as a service.
