Proposta da gestão de redes de computadores em ambientes vrtuais uilizando tecnologias AWS: um estudo prático no Instituto Médio Politécnico e Profissionalizante – IMED (2021-2023)

Abstract

The present study, titled “Proposal for Computer Network Management in Virtual Environments Using AWS Technologies: A Practical Study at the Instituto Médio Politécnico e Profissionalizante – IMED (2021- 2023)”, identifies that traditional computer network management faces issues with scalability, integration of new technologies, resource efficiency, and maintenance complexity. This highlights the need for virtual environment management for companies looking to optimise operations during growth. The study adopted qualitative and descriptive research, semi-structured interviews with IMED's administrator and network technician, document analysis, and content analysis. The simulation methodology using AWS technologies employed Amazon EC2 and VPC to create virtual instances and private networks, respectively, with secure connectivity via Internet Gateway and Security Groups. Route 53 and Elastic Load Balancing managed domains and balanced traffic. Automation tools like AWS CloudFormation, CLI, and SDKs standardized and automated the infrastructure, while Amazon CloudWatch was used for continuous monitoring, supporting the sustainable growth of IMED's network. The results revealed that IMED has a robust and well-managed network infrastructure with critical components like switches, routers, servers, storage devices, and wireless access points. This infrastructure ensures efficient and secure connectivity with real-time monitoring, strict security policies, and proactive maintenance. The contracted company prepares reports on the network infrastructure, used by the administrator to monitor performance, security, and support strategic decision-making. Virtualization with AWS technologies can mitigate identified challenges, offering flexibility, scalability, and efficiency. The AWS virtualized infrastructure improved network latency from 100 ms to 40 ms and reduced response time from 150 ms to 80 ms. Bandwidth increased from 1 Gbps to 10 Gbps, and CPU usage dropped from 85% to 50%. Availability increased from 99.5% to 99.9%, and operational costs became lower and scalable. CPU usage in the physical infrastructure ranged from 83% to 88%, while in the virtualized infrastructure, it ranged from 48% to 53%. Network latency in the physical infrastructure ranged from 98 ms to 107 ms, and in the virtualized infrastructure, it ranged from 38ms to 43ms. These improvements highlight the efficiency, scalability, and cost-benefit of AWS virtualization. Additionally, the solution's resilience, demonstrated in tests, ensures service continuity. The recommendation is clear: migrating to AWS is the ideal choice to ensure the institution's sustainable growth.
