Serverless computing separates function execution from state management. Simple retry-
based fault tolerance might corrupt the shared state with duplicate updates. Existing …

At the heart of state machine replication, the celebrated technique enabling decentralized
and secure universal computation, lies Atomic Broadcast, a fundamental communication …

Cloud services improve their availability by replicating data across sites in different
geographical regions. A variety of state-machine replication protocols have been proposed …

State machine replication (SMR) uses consensus as its core component for reaching
agreement among a group of processes, in order to provide fault-tolerant services. Most …

Many distributed systems, eg, state machine replication and distributed databases, rely on
establishing a consistent order of operations on groups of nodes in the system. Traditionally …

Memory disaggregation is an emerging data center architecture that improves resource
utilization and scalability. Replication is key to ensure the fault tolerance of applications, but …

Atomic multicast is a communication abstraction that allows for messages to be addressed to
and reliably delivered by multiple process groups, while ensuring a partial order on …

Strictly serializable (linearizable) services appear to execute transactions (operations)
sequentially, in an order consistent with real time. This restricts a transaction's (operation's) …

When put under stress, traditional state-machine replication protocols typically exhibit
response times that by far exceed the average level of normal-case operation. The common …

Cloud storage systems often adopt state machine replication (SMR) to ensure reliability and
availability. Most SMR systems use" full-copy" replication across all nodes, which leads to …
