Role-Based Access Control (RBAC) is the most widely used model for advanced access
control deployed in diverse enterprises of all sizes. RBAC critically depends on defining …

Storage as a Service (StaaS) is a vital component of cloud computing by offering the vision
of a virtually infinite pool of storage resources. It supports a variety of cloud-based data store …

Serverless computing is becoming increasingly popular, enabling users to quickly launch
thousands of shortlived tasks in the cloud with high elasticity and fine-grain billing. These …

We present BEAT, a set of practical Byzantine fault-tolerant (BFT) protocols for completely
asynchronous environments. BEAT is flexible, versatile, and extensible, consisting of five …

Windows Azure Storage (WAS) is a cloud storage system that provides customers the ability
to store seemingly limitless amounts of data for any duration of time. WAS customers have …

Amazon Aurora is a relational database service for OLTP workloads offered as part of
Amazon Web Services (AWS). In this paper, we describe the architecture of Aurora and the …

Distributed storage systems for large clusters typically use replication to provide reliability.
Recently, erasure codes have been used to reduce the large storage overhead of three …

Erasure codes, such as Reed-Solomon (RS) codes, are being increasingly employed in
data centers to combat the cost of reliably storing large amounts of data. Although these …

Erasure codes such as Reed-Solomon (RS) codes are being extensively deployed in data
centers since they offer significantly higher reliability than data replication methods at much …

We design flexible schemes to explore the tradeoffs between storage space and access
efficiency in reliable data storage systems. Aiming at this goal, two new classes of erasure …
