![]() ![]() Reasons for the growth of hypervisors and virtualization included better hardware capabilities, which would now allow a single machine to do more simultaneous work cost-control efforts that led to consolidation of servers improved security and reliability due to hypervisor architecture improvements and the ability to run OS-dependent applications on different hardware or OS environments. ![]() Jumping ahead to the mid-2000s, hypervisors took center stage when Unix, Linux and other Unix-like operating systems began to utilize virtualization technologies. The virtualization aspect allowed programmers to deploy and debug without jeopardizing the stability of the main production system and without having to deploy additional costly development systems. In the late 1960s and through the 1970s, most virtualization and hypervisor work was seen on mainframe computers developed by IBM, for use in building time-sharing systems, testing new operating system ideas or even exploring new hardware concepts. After virtualization and cloud, what’s left on premises?.The hypervisor drives the concept of virtualization by allowing the physical host machine to operate multiple virtual machines as guests to help maximize the effective use of computing resources such as memory, network bandwidth and CPU cycles. Usually done as software although embedded hypervisors can be created for things like mobile devices. Hypervisor definitionĪ hypervisor is a process that separates a computer’s operating system and applications from the underlying physical hardware. While the benefits of virtualization and cloud computing may now seem like old hat within the IT infrastructure, that wasn’t always the case, and it is hypervisor technology that has helped drive innovation in the world of cloud computing. Hypervisors often get overlooked as a technology in favor of the flashier concept of virtualization, but you can’t get to the fun of virtualization until you understand what a hypervisor does within a computing system. ![]()
