Groups, Subgroups and Auto-Sharding in Derecho: A Customizable RDMA Framework for Highly Available Cloud Services
نویسندگان
چکیده
Derecho is an RDMA-based distributed computing framework that unifies group membership management, consistent data replication and persistence. Applications are structured as top-level groups which can be split into subgroups or automatically sharded in a regular manner. To preserve membership invariants, Derecho adjusts subgroup membership as parent-group membership evolves. The resulting mix of features simplifies creation of cloud services.

Derecho: Group Communication at the Speed of Light
Today’s platforms provide surprisingly little help to developers of high-performance scalable services. To address this, Derecho automates the creation of complex application structures in which each member plays a distinct role. Derecho’s data plane runs a novel RDMAbased multicast protocol that scales exceptionally well. The Derecho control plane introduces an asynchronous monotonic logic pro...
متن کاملRDMAvisor: Toward Deploying Scalable and Simple RDMA as a Service in Datacenters
RDMA is increasingly adopted by cloud computing platforms to provide low CPU overhead, low latency, high throughput network services. On the other hand, however, it is still challenging for developers to realize fast deployment of RDMA-aware applications in the datacenter, since the performance is highly related to many low-level details of RDMA operations. To address this problem, we present a...
