Definition
A managed service is a third-party offering where an external provider takes responsibility for managing specific IT functions or infrastructure for a client. This arrangement allows organizations to outsource complex or time-consuming tasks, freeing up internal resources to focus on core business objectives. The provider typically operates under a service level agreement (SLA) that outlines performance expectations and responsibilities. For instance, a company might engage a managed service provider to handle its network security monitoring and incident response. This differs from simply purchasing software or hardware, as it involves ongoing management and support by the vendor. Understanding managed services is crucial for cloud security certifications like CCSP and AWS exams.
