At its core, our MultiSite solutions are based on our patented DConE technology, and is designed to ensure the uninterrupted delivery of critical data-based services. It provides a reliable and efficient infrastructure that minimizes service outages, optimizes your developer experience, and tackles the complexities of geographically dispersed clients.
Distributed Coordination Engine (DConE)
DConE enables active-active replication without single points of failure or scalability bottlenecks. DConE operates transparently from two perspectives: it does not alter the behavior of the underlying application (e.g. Subversion), and it preserves the illusion of a single server system performing at LAN-speed despite running on multiple servers being geographically dispersed. This capability is achieved through three key elements:
- • A highly efficient, fault-tolerant, and fully decentralized active-active replication algorithm.
- • A configurable quorum-based approach, requiring agreement among a subset of servers (nodes) rather than all nodes, for transaction ordering.
- • A design maximizing the efficient use of server and network resources to deliver LAN-speed performance over a WAN while ensuring one-copy equivalence of data across the distributed system.
