Abstract
The invention relates to a fault tolerance optimizing method of intermediate data in a cloud computing environment. The method comprises the following four steps of: 1. collecting a network load, task execution progress and position information; 2. judging and analyzing task input data and mainly judging a data generating position; 3. classifying working modes according to the current environmentand adjusting recourse allocation according to a control parameter; and 4. feeding back a backup condition and updating data backup information. In the invention, the frequency of node failure in thecloud computing environment is taken into consideration at first, the intermediate data is replicated according to the task finishing time requirement and the resource use condition, and real-time monitoring and flexible management are carried out on the network load and task execution progress so as to ensure that the replication of the intermediate data is realized for the system under the condition that performance is free from influence. The fault tolerance optimizing method provided by the invention has wide practical value and application prospect in the field of cloud computing data management.
