Queuing theory algorithm to find the minimal number of VMs to satisfy SLO response time

This paper presents a queuing algorithm to find the minimal number of VMs to satisfy Service Level Object (SLO) response time. Using queuing theory, the model guarantees SLO for cloud-hosted applications or services by using minimal number of resources with its maximum capacity. Our proposed algorithm reduces cost for both clients and service providers. Clients pay for the usable resources and the service providers provide minimum needed resources.
