Service Performance Evaluation of IaaS Cloud Computing Center Under Batch Arrivals
摘要
Abstract
An analytical model based on queue system is proposed to deal with performance analysis of cloud center under batch arrivals. Some important performance indicators are acquired at steady status;these indicators include blocking probability, instance service probability, percentile response time, average queue length, and so on. The system performance influenced by changing buffer size and batch arrivals size is analyzed through numerical simulation. The numerical simulation results indicate that when buffer size is increased, the system performance with batch arrivals is better than single arrival under the same queuing intensity, and the system performance decreases as the burstiness of the number of every batch arrivals increase.关键词
