Cloud-based services have introduced a new kind of workload composed mainly by short-lived, ephemeral processes. This is a significant departure from traditional virtualization workloads, where VMs (Virtual Machines) are expected to run uninterrupted for a large amount of time, even surviving Host migrations. New needs called for new optimization techniques, which in turn triggered the creation of specialized VMMs (Virtual Machine Monitors) and the adaptation of the existing ones, alongside with the development of new isolation techniques.

Enarx - Attested, Secured Execution with AMD’s SEV - Nathaniel McCallum, Red Hat, Inc. & David Kaplan, Advanced Micro Devices, Inc. AMD SEV (Secure Encrypted Virtualization) is a new CPU security technology available in AMD's EPYC processors and provides new levels of protection for virtualized workloads. AMD SEV can encrypt the memory and register state of VMs individually, isolating them from the hypervisor. Enarx is an open source project led by Red Hat, leveraging TEEs, and providing attestation and protection for run-time workloads. It is written in Rust and aims to reduce the number of trust relationships required when running executables in the private or public cloud. It currently supports AMD SEV, and this session will: a) Discuss SEV capabilities and roadmap; b) Introduce the Enarx architecture; c) Present some of the components of Enarx; d) Show a demonstration of an early set of Enarx capabilities.
