Managed Hosting
A Managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone. It is also known as dedicated hosting service, dedicated server. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc. Server administration can usually be provided by the hosting company as an add-on service. In some cases a dedicated server can offer less overhead and a larger return on investment. Dedicated servers are most often housed in data centers, similar to collocation facilities, providing redundant power sources and HVAC systems. In contrast to collocation, the server hardware is owned by the provider and in some cases they will provide support for your operating system or applications.
In a managed hosting environment, your provider owns and is responsible for the data center, network, devices, operating system and application infrastructure components, providing a stable operating environment for your applications. Your IT organization manages your applications and maintains full control over the operating system and application infrastructure. IT hosting, on the other hand, actually goes a step further and includes the management of your applications too.
Managed hosting provides more value than co location and dedicated hosting because it frees more of your IT personnel from mundane infrastructure related tasks, personnel that can now be reallocated to understanding and supporting your business more effectively. Managed hosting also provides greater responsiveness than fully outsourced solutions because it emphasizes a flexible bottom up approach to delivering value that puts you fully in control of your OS, application infrastructure and application.
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.
