Virtualização de Redes na Infraestrutura do Datacenter do Tribunal de Contas do Estado do Amapá

Abstract

Network virtualization emerges as a transformative paradigm for modernizing IT infrastructure in the public sector, representing a strategic alternative to overcome the limitations of traditional physical infrastructures. This research analyzes the implementation of Software Defined Networking (SDN) and Network Functions Virtualization (NFV) technologies in institutional data centers, focusing on resource optimization, strengthening information security, and streamlining operational costs. The proposed architecture is based on the consolidation of network functions onto virtualized platforms, enabling advanced traffic segmentation through VLANs and the implementation of granular security policies via micro-segmentation. The results demonstrate significant gains in operational flexibility, with a substantial reduction in service provisioning time and the capacity for dynamic adaptation to institutional demands. Regarding security, virtualization enables efficient isolation between network segments and the centralized implementation of policies, critical aspects for compliance with the Brazilian General Data Protection Law (LGPD). Economically, a significant reduction in the dependence on dedicated hardware is verified, with the consolidation of multiple functions onto unified platforms. It is concluded that network virtualization constitutes a viable and strategic solution for public agencies, promoting not only operational efficiency and security but also alignment with the digital transformation guidelines established in Brazilian legislation.
