A managed IT services provider (MSP) is most often information technology (IT) services provider that manages and assumes responsibility for providing a defined set of services to its clients either proactively or as the MSP (not the client) determines that services are needed.[26][27] Most MSPs bill an upfront setup or transition fee and an ongoing flat or near-fixed monthly fee, which benefits clients by providing them with predictable IT support costs. Sometimes, MSPs act as facilitators who manage and procure staffing services on behalf of the client. In such context, they use an online application called vendor management system (VMS) for transparency and efficiency. A managed service provider is also useful in creating disaster recovery plans, similar to a corporation's. Managed Service Providers tend to prove most useful to small businesses with a limited IT budget.[28]
Cloud computing has allowed managed IT services to expand beyond the regions and borders that would constrain the average break/fix IT through the adoption of Software as a Service (SaaS) technologies, as well as Infrastructure as a Service (IaaS) and Platform as a Service(PaaS) also. These capabilities allow managed IT services to scale at a rate dramatically larger and faster than in-house IT operation or break/fix providers.
