Efficient task scheduling in cloud computing can intuitively affect the resource configuration and operating cost of the entire system. However, task and resource scheduling in a cloud computing environment is an NP\u2010hard problem. In this paper, we propose a three\u2010layer scheduling model based on whale\u2010Gaussian cloud. In the second layer of the model, a whale optimization strategy based on the Gaussian cloud model (GCWOAS2) is used for multiobjective task scheduling in a cloud computing which is to minimize the completion time of the task via effectively utilizing the virtual machine resources and to keep the load balancing of each virtual machine, reducing the operating cost of the system. In the GCWOAS2 strategy, an opposition\u2010based learning mechanism is first used to initialize the scheduling strategy to generate the optimal scheduling scheme. Then, an adaptive mobility factor is proposed to dynamically expand the search range. The whale optimization algorithm based on the Gaussian cloud model is proposed to enhance the randomness of search. Finally, a multiobjective task scheduling algorithm based on Gaussian whale\u2010cloud optimization (GCWOA) is presented, so that the entire scheduling strategy can not only expand the search range but also jump out of the local maximum and obtain the global optimal scheduling strategy. Experimental results show that compared with other existing metaheuristic algorithms, our strategy can not only shorten the task completion time but also balance the load of virtual machine resources, and at the same time, it also has a better performance in resource utilization.<\/jats:p>","DOI":"10.1155\/2021\/5546758","type":"journal-article","created":{"date-parts":[[2021,6,10]],"date-time":"2021-06-10T23:06:05Z","timestamp":1623366365000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["GCWOAS2: Multiobjective Task Scheduling Strategy Based on Gaussian Cloud\u2010Whale Optimization in Cloud Computing"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2917-8198","authenticated-orcid":false,"given":"Lina","family":"Ni","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9507-3082","authenticated-orcid":false,"given":"Xiaoting","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0830-2890","authenticated-orcid":false,"given":"Xincheng","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5193-0687","authenticated-orcid":false,"given":"Jinquan","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,6,10]]},"reference":[{"key":"e_1_2_12_1_2","doi-asserted-by":"publisher","DOI":"10.1145\/1327512.1327513"},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1145\/2593512"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1145\/1721654.1721667"},{"key":"e_1_2_12_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2018.07.062"},{"key":"e_1_2_12_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/jiot.2017.2709814"},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2019.2942719"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10723-015-9359-2"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2014.07.030"},{"key":"e_1_2_12_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/tase.2013.2272758"},{"key":"e_1_2_12_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2013.12.034"},{"key":"e_1_2_12_11_2","doi-asserted-by":"publisher","DOI":"10.1145\/2556583"},{"key":"e_1_2_12_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10586-019-02951-z"},{"key":"e_1_2_12_13_2","doi-asserted-by":"publisher","DOI":"10.1007\/s13369-018-3261-8"},{"key":"e_1_2_12_14_2","doi-asserted-by":"publisher","DOI":"10.1142\/s021812661650119x"},{"key":"e_1_2_12_15_2","doi-asserted-by":"publisher","DOI":"10.1063\/1.5112236"},{"key":"e_1_2_12_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jocs.2017.09.016"},{"key":"e_1_2_12_17_2","doi-asserted-by":"crossref","unstructured":"SpringerT.andLinsteadE.
