Dedicated servers need security options so that you can protect your website against hackers, viruses, and breakage. Firewall configurations are important but time-consuming. Some hosting providers will provide extra built-in security features, so you do not have to worry about it and get started with your server without any security to install except for additional options that you may want.
Ok, buddy, are you having an aneurism? This thread wasn't made to promote anyone or anything - it was made to dispel misleading bullcrap from shitty, unscrupulous GSPs and try and encourage more people getting a dedicated box, after the constant pain we regularly see when yet another poor sap gets crap performance with no refund after cancellation of service from a GSP in the Squad server host community. Time and again we see the same complaints from people, about the same companies that prey on people with little technical know-how that just want to run a game server.
A dedicated server, or computing server, is a machine with its own dedicated physical resources. Unlike a virtual server, which uses a portion of a machine's physical resources for its virtualization technology, a dedicated server gives you access to all of the machine's available RAM, storage, and computing power. Applied to cloud computing, dedicated server solutions can also be referred to as 'bare-metal', highlighting the physical availability of the machine's resources in contrast to standard cloud solutions based on virtual instances.
Availability, price and employee familiarity often determines which operating systems are offered on dedicated servers. Variations of Linux and Unix (open source operating systems) are often included at no charge to the customer. Commercial operating systems include Microsoft Windows Server, provided through a special program called Microsoft SPLA. Red Hat Enterprise is a commercial version of Linux offered to hosting providers on a monthly fee basis. The monthly fee provides OS updates through the Red Hat Network using an application called Yum. Other operating systems are available from the open source community at no charge. These include CentOS, Fedora Core, Debian, and many other Linux distributions or BSD systems FreeBSD, NetBSD, OpenBSD.
