The bagel they save for the regulars. Don't skim, savour.
Summary
This article discusses the limitations of privacy in public cloud computing and explores technical approaches to enhance confidentiality for virtual machines (VMs). It examines how traditional Linux cloud stacks fall short in protecting VM memory from cloud providers and presents solutions being developed to create confidential VMs that maintain privacy even from the host infrastructure. The content focuses on technical implementations, security architectures, and the ongoing development work needed to rethink Linux's cloud infrastructure for enhanced data protection.
