A kind of job transfer scheduling algorithm based on Hadoop Deng, Van Tong, Peak cloud environment Service cluster There is a problem of non-uniform distribution in job submission, which leads to the aggregation of jobs at one time, which causes the response time of the job to exceed the user tolerance range. To solve this problem, a queue based job transfer scheduling strategy (JTSA) is proposed under the Hadoop platform using two-level queue technology. The experimental results show that in the case of a sharp increase in the number of operations, the total completion time has little effect and can be more significant ...

Predicting cloud platform service performance trends using moving averages Chen Guang reckons, Baixiaoying, Huang, Li Yangyang, weekly column system performance prediction provides a basis for predictive resource scheduling and an important aspect of cloud platform management. The method of performance prediction is summarized from three aspects of data, processing and forecasting. In this paper, a moving average line method is proposed to predict the long-term development trend of service performance. Aiming at the problem that the prediction signal will be changed frequently in the performance small range fluctuation, this method is further improved and the standard deviation is introduced to effectively filter the jitter signal. In the Amazon Elastic Computing cloud environment ...

A database engine for large-scale data processing Wang Yi, Liu Great Wall, Ma Jianqing when data volumes rise from GB to terabytes or even petabytes, high-performance parallel databases can be computationally costly to ensure scalability and fault tolerance.
