A dedicated server is most appropriate when any of the following apply:
- you expect your site or application to generate a high volume of traffic and you don't want to compete with other sites on a shared server for resources.
- you have specific setup requirements (operating system, Apache version, php version, special software) not filled by shared servers.
- your site is mission-critical and can tolerate no downtime, even from server reboots. Dedicated servers are rebooted only when doing so meets the needs of the single customer using it.
- You need maximum security and don't want a server that also hosts other customers.
Operating systems supported include Linux (RedHat, CentOS, Debian, Ubuntu) and FreeBSD.
