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.
In House—the process where an organization hires its own IT service providers and pays their salary, benefits, and further training, as well as the infrastructure they oversee. This is typically an extremely costly endeavor, and often businesses that try to procure in-house IT lack the capabilities to fully service their system as well as an inability to grow.
