Technology is advancing day by day, but nothing disappears; only the new things come up one step above the existing technology. Same thing occurred in the field of Operating Systems. General operating system can be thought of as heavy system software which works as a platform for other application software to run over the existing machine and efficiently utilizing the resources, although conventions operating systems itself consumes heavy system resources such as memory for their operations and disk space for installation. But with the advent of cloud OS the scenario has been changed. Now the operating system requires no more installation. In this paper, we enlighten the evolutionary journey of cloud operating systems and their revolutionary benefits.
