The evolution of MSP started in the 1990s with the emergence of application service providers (ASPs) who helped pave the way for remote support for IT infrastructure. From the initial focus of remote monitoring and management of servers and networks, the scope of an MSP's services expanded to include mobile device management, managed security, remote firewall administration and security-as-a-service, and managed print services. Around 2005, Karl W. Palachuk, Amy Luby (Founder of Managed Service Provider Services Network acquired by High Street Technology Ventures), and Erick Simpson (Managed Services Provider University) were the first advocates and the pioneers of the managed services business model.
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.
