| The Linux Virtual Server Project is an open source project to cluster many real servers together into a highly available, high-performance virtual server. The LVS handles connections from clients and passes them on the the real servers (so-called Layer 4 switching) and can virtualize almost any TCP or UDP service, like HTTP, HTTPS, NNTP, FTP, DNS, ssh, POP3, IMAP4, SMTP, etc.; it is fully transparent to the client accessing the virtual service. |
