The Allocation of Cloud Computing Resources Based on the Improved Ant Colony Algorithm Cloud computing is the development of distributed computing, parallel computing and grid computing, or defined as the commercial implementation of these computer science concepts. The allocation of cloudcomputing resource is a hot topic. Many scholars have done some research in this area. In this paper, we adopt the improved ant colony optimization algorithm to compute the allocation of the cloudcomputing resource and to analyze the impact of bandwidth, the load of network and response time on the cloud resource. Analysis and simulation results show that the throughput is increased and the response time isreduced based on the improved ACO compared with the routing algorithm (OSPF).
