Research on dynamically detecting SLA violation for multi-resources
Chen Lian · Jisuanji gongcheng yu sheji · 2014
To solve the problem of SLA violation caused by different resources of different jobs,a method for dynamically checking SLA violation and its algorithm are proposed,which are both based on a SLA model for different resources,such as CPU,ram and disk.By reserving partial resources or recycling pieces of resources for the VMs(virtual machines)which are mostly possible to violate SLAs,it promotes utilization of different resources greatly on a host as a whole and satisfies the requirement for different resources of jobs.By modeling a distributed multi-queue system,and conducting simulation of the mentioned model and algorithm,the correctness of the model and feasibility of the algorithm are verified,SLA violation is reduced and execution of jobs is accelerated.
