Internet Week: A Single Image For LinuxMay 16, 2000, 15:03 (0 Talkback[s])
"A small company called Linux Networx has developed software that creates single-system-image clusters of multiple Linux systems, which could make the platform more suitable for database apps. With a single system image, all of the servers on a network look and function like one computer."
"Single-system-image clustering is more robust than other kinds of clustering technology available: failover clustering, where if one server fails, another server in the cluster can take over its workload; load balancing, where multiple servers balance the workload; and message passing, which includes the Beowulf technology for Linux. Beowulf is an open source effort that allows multiple systems to perform parallel processing on the same task. But that sort of clustering is suited to scientific and technical applications rather than commercial and Internet computing."
"The Linux Networx software is based on standard, open source technology called BPROC, which allows servers to spawn programs or processes on other servers. The software clones a master server's software onto multiple servers, to help users quickly set up clusters of large numbers of machines."
