OpenVZ Virtualization Keeps E-mail Filtering Service Up and Running
JunkEmailFilter.com Uses Operating System Virtualization to Manage its Network of Servers
For higher levels of control and security, JunkEmailFilter.com uses open source virtualization software, known as OpenVZ, to sort through e-mail to filter out viruses and junk e-mails so that its clients only receive the e-mails they want to see.
“In our business, it’s a necessity to have redundant systems in different locations in case bad things happen,” says Marc Perkel, support manager at JunkEmailFilter.com. “People are dependent on us to get their e-mail through, so we cannot afford downtime.”
The company has set up virtual servers with OpenVZ operating system server virtualization software and maintains backups so that, if necessary, a virtual server can be restored on another physical server and started up immediately.
