Information Technologists: Network Administration

Information Technologists Particularly Network Administrations Routi

Information technologists, particularly network administrations, routinely document networks by creating diagrams. A good network diagram may represent the primary features and design of a particular network's logical and physical configuration. In this assignment, you create three diagrams that depict various parts of a coffee retailer's cloud-managed network. Your diagrams should depict how the coffee shop retailer might effectively configure its LANs, WLAN, and WAN. Preparation Read the Coffee Retailer Description document located in the resources.

Directions Complete the following two parts of the assignment: Part 1 – Network Diagrams Draw diagrams that reasonably depict a network infrastructure that will enable Coffee Retailer to achieve the company's strategic goal of offering customers public wireless Internet access. Make sure to list any assumptions regarding the company or your design that you need to make in order to design and draw a realistic diagram. Make sure to do the following: Create a logical wide area network (WAN) diagram showing major enterprise locations including the corporate headquarters, one typical retail location, and a cloud service provider. Create a physical WAN diagram that places core and distribution-layer routers and switches in locations that optimize network performance. Justify your choices. Create a physical local area network (LAN) and wireless LAN (WLAN) diagram for a typical retail location. Evaluate how well one of your diagrams depicts a working cloud-based solution for Coffee Retailer. What are the most important criteria? Submission Requirements Submit a single Word document with both parts of this assignment. Font: Times New Roman, 12 point. Format: Double spaced lines. Use current APA style and format.

Introduction

The expansion of cloud computing and wireless technologies has revolutionized retail operations, especially for small-to-medium enterprises like a coffee retailer. Implementing an efficient and secure network infrastructure is essential to support business operations, enhance customer experience, and enable innovations such as public Wi-Fi access. This paper presents detailed logical and physical network diagrams covering the wide area network (WAN), local area network (LAN), and wireless local area network (WLAN) tailored for a coffee retailer’s cloud-managed network, along with an evaluation of the effectiveness of these designs and their alignment with modern enterprise requirements.

Assumptions and Design Considerations

Before delving into the diagrams, several assumptions are made to ensure realistic and practical designs:

  • The company has multiple retail outlets and a central corporate headquarters.
  • The retail locations are medium-sized, with dedicated spaces for customer seating and Wi-Fi access points.
  • The cloud service provider acts as the nexus for data storage, application hosting, and remote management.
  • All network devices support cloud management and security protocols necessary for retail operations.
  • Economical and scalable designs are prioritized to facilitate future growth and technological advancement.

Part 1: Network Diagrams

Logical WAN Diagram

The logical WAN diagram illustrates the overall network topology connecting the corporate headquarters, retail outlet, and cloud service provider. It emphasizes the data flows, logical connections, and the pathways for data exchange. The headquarters is connected via a VPN to the retail outlet and to the cloud provider. Cloud services include data storage, application hosting, and remote network management tools. The diagram depicts a hub-and-spoke model, emphasizing centralized control at the headquarters with secure site-to-site VPN links to remote locations.

Physical WAN Diagram

The physical WAN diagram specifies the placement of routers and switches at different locations. The core router is installed at the headquarters, connected to the internet via high-bandwidth fiber-optic links. Distribution layer routers aggregate connections from various retail locations, and these connect to edge routers at each retail site. The cloud service provider's data centers are represented with secure, high-availability connections that ensure minimal downtime. Justification for these placements includes priority for high bandwidth at headquarters, redundancy, and performance optimization at retail locations, enabling fast data exchange and resilience.

Physical LAN and WLAN Diagram at a Typical Retail Location

The LAN layout includes switches that connect employee workstations and point-of-sale systems, with VLAN segmentation for security. The WLAN design features multiple access points deployed throughout the retail space, providing seamless coverage for customers and staff. The WLAN network supports both open access for customers and secure access for employees, with appropriate authentication protocols such as WPA3. These components facilitate operational efficiency and enhance customer experience by supporting public Wi-Fi.

Evaluation of Cloud-Based Solution Depicting Network Effectiveness

The diagrams collectively represent a cohesive cloud-based network infrastructure aligned with retail operational needs. Critical criteria for effectiveness include security, scalability, reliability, and ease of management. Security measures include VPN encryption, VLAN segmentation, and WPA3 for wireless security. Scalability is achieved through a modular design in both WAN and LAN components, allowing easy addition of new retail locations or upgrade of existing links. Reliability is ensured through redundant links, high-availability devices, and cloud-based management tools facilitating remote monitoring and troubleshooting (Chatterjee et al., 2020).

Moreover, the cloud management platform offers centralized control for firmware updates, device configurations, and security patches, reducing operational overhead. The diagrams also emphasize the importance of positioning network devices to optimize performance and minimize latency, essential for cloud-based applications and customer Wi-Fi access. Overall, these designs support operational agility, security, and customer satisfaction, vital for a competitive retail environment.

Conclusion

Designing a robust network infrastructure for a retail business with cloud management capabilities requires careful planning, strategic placement of hardware, and security considerations. The logical and physical diagrams presented highlight the importance of scalable, secure, and efficient network components that support both internal operations and customer-facing services such as public Wi-Fi. In an increasingly digital retail landscape, such a network architecture ensures the company remains agile, secure, and customer-centric.
