A Placement Vulnerability Study in Multi-tenant Public Clouds
Public infrastructure-as-a-service clouds, such as Amazon EC2, Google Compute Engine (GCE) and Microsoft Azure allow clients to run virtual machines (VMs) on shared physical infrastructure. This...
MANTA: Machine Learning Augmented Tiering Advisor
Memory tiering has been used to expand memory capacity, particularly in datacenters, by combining fast DRAM with slower tiers, including CXL-attached memory. Its effectiveness depends on keeping...
It's a Feature, Not a Bug: Secure and Auditable State Rollback for Confidential Cloud Applications
It's a Feature, Not a Bug: Secure and Auditable State Rollback for Confidential Cloud Applications
Replay and rollback attacks threaten cloud application integrity by reintroducing authentic yet stale data through an untrusted storage interface to compromise application decision-making. Prior...
ARMS: Adaptive and Robust Memory Tiering System
Memory tiering systems seek cost-effective memory scaling by adding multiple tiers of memory. For maximum performance, frequently accessed (hot) data must be placed close to the host in faster...
From Good to Great: Improving Memory Tiering Performance Through Parameter Tuning
Memory tiering systems achieve memory scaling by adding multiple tiers of memory wherein different tiers have different access latencies and bandwidth. For maximum performance, frequently accessed...
Efficient Storage Integrity in Adversarial Settings
Storage integrity is essential to systems and applications that use untrusted storage (e.g., public clouds, end-user devices). However, known methods for achieving storage integrity either suffer...
On Scalable Integrity Checking for Secure Cloud Disks
Merkle hash trees are the standard method to protect the integrity and freshness of stored data. However, hash trees introduce additional compute and I/O costs on the I/O critical path, and prior...
Examem: Low-Overhead Memory Instrumentation for Intelligent Memory Systems
Memory performance is often the main bottleneck in modern computing systems. In recent years, researchers have attempted to scale the memory wall by leveraging new technology such as CXL, HBM, and...
