The clients\u2019 high availability requirement is a challenge because it limits the possible admission control in front of the edge cloud. This work proposes an orchestrator with a mathematical programming model in a global viewpoint to solve resource management problems and satisfying the clients\u2019 high availability requirements. The proposed Lagrangian relaxation-based approach is adopted to solve the problems at a near-optimal level for increasing the system revenue. A promising and straightforward resource management approach and several experimental cases are used to evaluate the efficiency and effectiveness. Preliminary results are presented as performance evaluations to verify the proposed approach\u2019s suitability for edge and core cloud computing environments. The proposed orchestrator significantly enables the network slicing services and efficiently enhances the clients\u2019 satisfaction of high availability.<\/jats:p>","DOI":"10.3390\/s21051882","type":"journal-article","created":{"date-parts":[[2021,3,8]],"date-time":"2021-03-08T12:12:18Z","timestamp":1615205538000},"page":"1882","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Optimization-Based Resource Management Algorithms with Considerations of Client Satisfaction and High Availability in Elastic 5G Network Slices"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8475-7400","authenticated-orcid":false,"given":"Chiu-Han","family":"Hsiao","sequence":"first","affiliation":[{"name":"Research Center for Information Technology Innovation, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank Yeong-Sung","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Information Management, National Taiwan University, Taipei 10617, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1907-2691","authenticated-orcid":false,"given":"Evana Szu-Han","family":"Fang","sequence":"additional","affiliation":[{"name":"Department of Information Management, National Taiwan University, Taipei 10617, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Fang","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Information Management, National Taiwan University, Taipei 10617, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yean-Fu","family":"Wen","sequence":"additional","affiliation":[{"name":"Graduate Institute of Information Management, National Taipei University, New Taipei City 23799, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yennun","family":"Huang","sequence":"additional","affiliation":[{"name":"Research Center for Information Technology Innovation, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang-Che","family":"Su","sequence":"additional","affiliation":[{"name":"Research Center for Information Technology Innovation, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ya-Syuan","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Information Management, National Taiwan University, Taipei 10617, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsin-Yi","family":"Kuo","sequence":"additional","affiliation":[{"name":"Research Center for Information Technology Innovation, Academia Sinica, Taipei 115, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"80","DOI":"10.1109\/MCOM.2017.1600935","article-title":"Network Slicing for 5G with SDN\/NFV: Concepts, Architectures, and Challenges","volume":"55","author":"Ameigeiras","year":"2017","journal-title":"IEEE Commun.
