Avocado - A Secure In-Memory Distributed Storage System
Explore a conference talk introducing Avocado, a secure in-memory distributed storage system designed for untrusted cloud environments. Delve into the system's architecture, which combines Trusted Execution Environments (TEEs) with innovative solutions to overcome hardware limitations and extend trust to distributed settings. Learn about Avocado's cross-layer contributions, including a trusted network stack, fault-tolerant replication protocol, and scalable memory management. Discover how this system achieves strong security, fault-tolerance, consistency, and performance, outperforming traditional Byzantine Fault Tolerance (BFT) approaches. Gain insights into Avocado's practical implementation and its significant speed improvements for YCSB workloads compared to existing solutions.
