This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc.
Dedicated servers are hosted in data centers, often providing redundant power sources and HVAC systems.
[citation needed] Using a dedicated hosting service offers the benefits of high performance, security, email stability, and control.
[citation needed] Availability, price and employee familiarity often determines which operating systems are offered on dedicated servers.
[3] Red Hat Enterprise is a commercial version of Linux offered to hosting providers on a monthly fee basis.
These include CentOS, Fedora Core, Debian, and many other Linux distributions or BSD systems FreeBSD, NetBSD, OpenBSD.
[citation needed] Support for any of these operating systems typically depends on the level of management offered with a particular dedicated server plan.
To achieve the same type of network without a multi-provider blend of bandwidth, a large investment in core routers, long term contracts, and expensive monthly bills would need to be in place.
The expenses needed to develop a network without a multi-provider blend of bandwidth does not make sense economically for hosting providers.
Bandwidth was traditionally measured inline speed access that included the ability to purchase needed megabits at a given monthly cost.
Providers will often deploy various software programs for scanning systems and networks for obtrusive invaders, spammers, hackers, and other harmful problems such as Trojans, worms, and crashers (Sending multiple connections).
They have since started introducing pricing models that allow dedicated hosting providers the ability to purchase and resell software based on reduced monthly fees.
This is due to rogue IRC users triggering DDoS attacks against the provider, which may overwhelm their networks, lowering service quality for all customers.
