Paper For Above Instructions

In the modern landscape of information technology, choosing the appropriate architecture for software systems is paramount. This paper aims to present a summary of the chosen architectural design along with the hardware and software specifications that support the deployment of the application. For this purpose, we will analyze both client-server architecture options and the associated hardware/software requirements.

Architectural Design Summary

For the architecture of our application, we have opted for a 3-Tiered Client-Server architecture. This architecture comprises three distinct layers: the presentation layer (client), the application layer (server), and the database layer (data server). The rationale behind selecting the 3-Tiered architecture lies in its scalability, maintainability, and ease of deployment. Compared to 2-Tiered architectures, the 3-Tiered system separates concerns more effectively and allows for independent scaling of each layer, leading to improved performance under load (Shahin et al., 2021).

In choosing between Thin Client and Thick Client systems, we have selected a Thin Client model. This choice favors simplicity in client-side management because most operations and processing are handled on the server side, which decreases the need for powerful client devices (Voller et al., 2020). The Thin Client architecture also offers enhanced security, as sensitive data is not stored locally and minimizes the potential attack surface on client devices.

Hardware/Software Specification Summary

The hardware and software specifications for this architecture must account for both client and server requirements. The chosen architecture demands specific configurations that ensure optimal performance and reliability across all layers.

Client Requirements

For our Thin Clients, we need to ensure that the devices meet basic operational needs without requiring significant processing power. The specifications are as follows:

  • Hardware: Standard Desktop or Laptop with a minimum of 4 GB RAM, Intel i3 processor, and at least 128 GB SSD.
  • Software: Operating System options can include Windows 10 or Ubuntu 20.04 LTS.
  • Network: Minimum 100 Mbps internet connection for efficient operation.

Server Requirements

The servers must be equipped with powerful specifications to handle multiple simultaneous requests and data processing. The specifications are:

  • Application Server:
    • Hardware: 16 GB RAM, Quad-Core Processor, 500 GB SSD or HDD.
    • Software: Windows Server 2019 or Linux distribution with the necessary application server software.
  • Database Server:
    • Hardware: 32 GB RAM, 8-Core Processor, RAID-configured storage (1 TB).
    • Software: SQL Server 2019 or MySQL (latest stable version).

Network Requirements

The network infrastructure must support both server communication and client access efficiently. The following network requirements are recommended:

  • Router with gigabit speed and support for VLANs.
  • Switches with at least 24 ports for internal network distribution.
  • Firewall to ensure secure communication between clients and servers.

Conclusion

In conclusion, the selected 3-Tiered Thin Client architecture provides a robust solution to meet the needs of modern software applications, ensuring scalability, security, and ease of management. The hardware specifications laid out serve to underpin the effectiveness of this architecture, facilitating optimal performance for both clients and servers. This comprehensive approach ensures that the system can adapt to future demands while maintaining an efficient and effective operating environment.
