A Strategy to Improve the Efficiency of I/O Intensive Application in Cloud Computing Environment

An I/O intensive application is one of the most common applications in cloud computing, which is a dominant type in some occasions. However, few studies have focused on how to improve the processing efficiency of such specific type of applications. We have found out the performance bottlenecks based on the features obtained from I/O-intensive applications. By analyzing the features of files, we put forward a packagebased strategy. It means all small sized files are packaged before the specific I/O operations by using this kind of applications. This can remarkably shorten the time of addressing files and fully use of the I/O resources. To verify the strategy, we have done extensive experiments. The experimental results show the packaging strategy can efficiently improve the processing efficiency of I/O-intensive applications in cloud computing, which can be beneficial for increasing the resource efficiency of cloud data centers.
