Major cloud providers such as Amazon, Google and Microsoft provide nowadays some form of infrastructure as a service (IaaS) which allows deploying services in the form of virtual machines, containers or bare-metal instances. Although software-based solutions like homomorphic encryption exit, privacy concerns greatly hinder the deployment of such services over public clouds. It is particularly difficult for homomorphic encryption to match performance requirements of modern workloads. Evaluating simple operations on basic data types with HElib, a homomorphic encryption library, against their unencrypted counter part reveals that homomorphic encryption is still impractical under realistic workloads.
