There is an increasing demand to cloud services in the market. In terms of cost and benefit, it is obvious that cloud services lowered investment cost and fixed cost for businesses. Thus, an economic perspective towards cloud services is required for strategic decisions. In this paper, a preliminary evaluation of cloud services was presented, and the common economic issues were identified. Regarding to these issues, the latency was addressed from the economic perspective, and a testing environment was created and implemented in 5 different cases. The results were given in the paper outlining impact of latency in terms of concurrent users and bandwidth allocation. Finally, an alternative cost estimation was proposed.
