Improvement and Modernization of Corporate Virtualization Infrastructure: An Approach to Mitigate Risks and Enhance Efficiency
| Resumo: | This dissertation investigates the modernization of a corporate virtualization estate whose Nuxis-based platform has reached end-of-life. A risk-driven evaluation framework is defined to compare technical, operational, and economic options, supported by a state-of-the-art synthesis of hypervisors and management stacks. Requirements and acceptance criteria are made explicit to guide decision-making across availability, disaster recovery, security/governance, observability, automation, and cost (TCO/ROI). A controlled proof-of-concept (PoC) validates key platform behaviors on a single representative virtual machine, exercising live migration, backup/restore, remote backup replication, centralized log forwarding, and API/RBAC enforcement. The results indicate feasibility under laboratory constraints and outline a migration path consistent with a hybrid strategy. The work does not include formal performance or scalability benchmarks; external validity is therefore limited and discussed as a threat. Future work proposes a staged pilot (8–12 heterogeneous VMs) with capacity exercises and production-grade economic assessment to generalize the findings. |
