ORC - Increasing Cloud Memory Density via Object Reuse with Capabilities

Explore a 15-minute conference talk from OSDI '23 that introduces Object Reuse with Capabilities (ORC), a novel approach to increase cloud memory density. Delve into the challenges of memory de-duplication in multi-tenant cloud environments and learn how ORC addresses these issues by supporting fine-grained sharing of binary objects while maintaining strong tenant isolation. Discover how ORC leverages hardware support for memory capabilities, implements a new relocation type for per-tenant state creation, and allows untrusted guest object loading with safety verification. Examine the experimental results demonstrating ORC's superior memory density and lower overhead compared to hypervisor-based de-duplication methods. Gain insights from researchers at Imperial College London, University of Otago, and The University of Tokyo as they present their innovative solution for optimizing cloud resource utilization.
