This report provides a comprehensive IT infrastructure proposal for Technosavy Limited, addressing the company's need for a more scalable, secure, and manageable network. The proposal includes an analysis of the current flat network model and its limitations, followed by a detailed design based on a three-layered hierarchical model (Access, Distribution, and Core layers). It outlines the required hardware and software components, including servers, network devices, and operating systems. The report also proposes a network IP addressing scheme, explores cloud-based design options with service provider recommendations (CtrlS Cloud and Microsoft Azure), and discusses dynamic application scaling using virtualization and cloud technologies. Finally, the report presents a network simulation using Cisco Packet Tracer, demonstrating DHCP, DNS, and web server configurations, and illustrates how clients dynamically obtain network configurations and access the web server. The report concludes with recommendations for Technosavy Limited to enhance their network infrastructure.
