Such servers dynamically cater to the on-demand requests put forward by the clients seeking solutions to their applications through an interface. The scheduling activity concerned with scientific applications is designated under the NP hard problem category since they make use of heterogeneous resources of dynamic capabilities. Recently cloud computing researchers had developed numerous meta-heuristic approaches for providing solutions to the challenges arising in the task scheduling activities. Scheduling of tasks poses a major concern in cloud computing environment. This decreases the efficiency of the system considerably, if not handled properly. Hence, an improvised task scheduling algorithm that enhances the performance of the cloud is needed. There are two factors that affect the cloud environment: service quality and energy usage. To increase the performance in above suggested factors (memory, makespan and energy efficiency), an efficient hybridized algorithm, obtained by integrating the Cuckoo Search Algorithm (CSA) and Whale Optimization Algorithm (WOA), called the CWOA had been proposed in this work. The performance of our proposed CWOA algorithm had been compared with Ant Colony Optimization, CSA and WOA and it was found to produce an improvement of 5.62%, 4.36% and 2.27% with respect to makespan, 16.36%, 19.19% and 13.13% with respect to memory utilization and 19.08%, 19.34% and 16.75% with respect to energy consumption parameters, respectively. Comprehensive results have been tabulated in the result section of this article.<\/jats:p>","DOI":"10.1093\/comjnl\/bxab028","type":"journal-article","created":{"date-parts":[[2021,3,18]],"date-time":"2021-03-18T20:11:12Z","timestamp":1616098272000},"page":"1860-1873","source":"Crossref","is-referenced-by-count":17,"title":["CWOA: Hybrid Approach for Task Scheduling in Cloud Environment"],"prefix":"10.1093","volume":"65","author":[{"given":"K","family":"Pradeep","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering , , Chennai, Tamilnadu 600 127, India"},{"name":"Vellore Institute of Technology , , Chennai, Tamilnadu 600 127, India"}]},{"given":"L Javid","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of IT , , Chennai, Tamilnadu 600 119, India"},{"name":"St. Joseph\u2019s Institute of Technology , , Chennai, Tamilnadu 600 119, India"}]},{"given":"N","family":"Gobalakrishnan","sequence":"additional","affiliation":[{"name":"Department of IT , , Chennai, Tamilnadu 600 119, India"},{"name":"St. Joseph\u2019s College of Engineering , , Chennai, Tamilnadu 600 119, India"}]},{"given":"C J","family":"Raman","sequence":"additional","affiliation":[{"name":"Department of IT , , Chennai, Tamilnadu 600 119, India"},{"name":"St. Joseph\u2019s College of Engineering , , Chennai, Tamilnadu 600 119, India"}]},{"given":"N","family":"Manikandan","sequence":"additional","affiliation":[{"name":"Department of CSE , , Chennai, Tamilnadu 600 119, India"},{"name":"St. Joseph\u2019s College of Engineering , , Chennai, Tamilnadu 600 119, India"}]}],"member":"286","published-online":{"date-parts":[[2021,5,3]]},"reference":[{"key":"2022071813385707000_ref1","doi-asserted-by":"crossref","first-page":"640","DOI":"10.1016\/j.future.2015.08.006","article-title":"Symbiotic organism search optimization based task scheduling in cloud computing environment","volume":"56","author":"Abdullahi","year":"2016","journal-title":"Future Gener.
