As 5G systems evolve, efficient resource allocation and the optimization of Quality-of-Service (QoS) metrics, including response time, energy efficiency, scalability, and resource utilization, have become increasingly critical. Given the scheduler\u2019s central role in orchestrating containerized workloads, this study analyzes diverse scheduling strategies designed to address these competing objectives. A novel taxonomy is introduced to categorize existing approaches, offering a structured view of deterministic, heuristic, and learning-based methods. Furthermore, the review identifies key research challenges, highlights open issues, such as QoS-aware orchestration and resilience in distributed environments, and outlines prospective directions to advance multi-objective scheduling in Kubernetes for next-generation networks. By synthesizing current knowledge and mapping research gaps, this work aims to provide both a foundation for newcomers and a practical reference for advancing scholarly and industrial efforts in the field.<\/jats:p>","DOI":"10.3390\/computers14090390","type":"journal-article","created":{"date-parts":[[2025,9,15]],"date-time":"2025-09-15T16:27:33Z","timestamp":1757953653000},"page":"390","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Optimizing Kubernetes with Multi-Objective Scheduling Algorithms: A 5G Perspective"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9555-7781","authenticated-orcid":false,"given":"Mazen","family":"Farid","sequence":"first","affiliation":[{"name":"Faculty of Information Science and Technology (FIST), Multimedia University, Melaka 75450, Malaysia"},{"name":"Centre for Intelligent Cloud Computing, COE for Advanced Cloud, Multimedia University, Melaka 75450, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heng Siong","family":"Lim","sequence":"additional","affiliation":[{"name":"Faculty of Engineering and Technology, Multimedia University, Melaka 75450, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3679-8977","authenticated-orcid":false,"given":"Chin Poo","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Computer Science, University of Nottingham Ningbo China, 199 Taikang East Road, Yinzhou District, Ningbo 315100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charilaos C.","family":"Zarakovitis","sequence":"additional","affiliation":[{"name":"ICT Department, axon logic IKE, 14122 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7637-9158","authenticated-orcid":false,"given":"Su Fong","family":"Chien","sequence":"additional","affiliation":[{"name":"ICT Department, axon logic IKE, 14122 Athens, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"957","DOI":"10.1109\/COMST.2021.3067807","article-title":"Survey on Network Slicing for Internet of Things Realization in 5G Networks","volume":"23","author":"Wijethilaka","year":"2021","journal-title":"IEEE Commun.
