Cloud computing is a method of delivering computing resources. In fact cloud computing has emerged as a new paradigm for hosting and delivering services over the Internet. Cloud computing services ranging from data storage and processing to software, such as customer relationship management systems, are now available instantly and on demand. Virtualization facilitates the provision of flexible resources and improves energy efficiency through the consolidation of virtualized servers into a smaller number of physical servers. Virtualization and Application of virtual machines in cloud computing is a cutting edge theory and in most of related works was described as a progressive architecture in processing jobs and allocating resources. However application of virtual machines imposes its own disadvantages in computing. In this paper an approach for processing services is presented considering elimination of virtual machine and its disadvantages. This approach considers delivering of services based on users request and operating systems instead of establishing new virtual machine for each new service request. Simulation results showed that the VM-free approach has had the characteristics and advantages of other methods and furthermore has improved drawbacks
