A managed IT service is an information technology (IT) task provided by a third-party contractor and delivered to a customer.
In a managed service arrangement, the managed service provider retains responsibility for the functionality of the IT service and equipment, and the customer typically pays a monthly fee for receipt of the service. There are many different types of managed IT service offerings, but the idea behind all of them is to transfer the burden of maintaining IT from the customer to a service provider. In an effective managed services relationship, a customer benefits from predictable pricing and the ability to focus on core business concerns rather than IT management chores.
