The LAMP system is very popular and is all based on OpenSource technology. We can manage and host your server and configure Linux machines to your needs. System administration is a daily routine for us. We use a variety of platforms including OSX, Red Hat, Centos and Ubuntu for development. This text is being written on a Ubuntu machine! We do not use or recommend Microsoft Server technology unless absolutely necessary. If you are currently contracted to a MS vendor you may be interested in the advantages of migrating to a Linux or OSX platform.
