===== Technology: Remus Project Brings Transparent High Availability To Xen on Wednesday November 11, @05:48PM Posted by timothy on Wednesday November 11, @05:48PM from the when-servers-go-south-a-song dept. An anonymous reader writes "The Remus project has just been incorporated into the Xen hypervisor. Developed at the University of British Columbia, Remus provides a thin layer that continuously replicates a running virtual machine onto a second physical host. Remus requires no modifications to the OS or applications within the protected VM: on failure, Remus activates the replica on the second host, and the VM simply picks up where the original system died. Open TCP connections remain intact, and applications continue to run unaware of the failure. It's pretty fun to yank the plug out on your web server and see everything continue to tick along. This sort of HA has traditionally required either really expensive hardware, or very complex and invasive modifications to applications and OSes." ===== -- Soh Kam Yung my Google Reader Shared links: (http://www.google.com/reader/shared/16851815156817689753) my Google Reader Shared SFAS links: (http://www.google.com/reader/shared/user/16851815156817689753/label/sfas) _______________________________________________ LUGS Mailing list - [email protected] List FAQ: http://wiki.lugs.org.sg/LugsMailingListFaq Info page: http://www.lugs.org.sg/mailman/listinfo/slugnet To unsubscribe send an empty email to: [email protected]
