A Managed Network Service Provider is usually a company that provides a number of hosted IT services for you. These managed network services can vary from Internet access and email to Managed DNS and Database applications.
The Managed service provider can alleviate the IT strain on your company and ensure that specialist expertise is always available when something is wrong.
For example,Managed hosting is one such service which is essentially a dedicated server that is
complimented by a full suite of maintenance, technical support, and monitoring services. This is
different from dedicated Web hosting which although customers are provided with their own
servers, they are still responsible for most of the administrative and maintenance duties.
Unmanaged services on the other hand , give the customer complete remote server administration freedom and capability. However a large amount of time and technical expertise is required, as you are solely responsible for the management of the server not the managed hosting provider.
For this reason,unmanaged servers and other services are only recommended for individuals and companies with extensive server or IT administration resources or expertise.
