System Requirements Document (SRD)

Project Name: azure-vpn

1. Introduction

The azure-vpn project is a cutting-edge Virtual Private Network (VPN) application designed to prioritize security, privacy, and ease of use for a broad audience. Developed with the needs of users in Pakistan (PK) in mind, this project aims to deliver a seamless and secure internet experience. The application will cater to both individual users and businesses, ensuring robust encryption, reliable server connections, and user-friendly controls.

This document outlines the system requirements for the azure-vpn project, including functional and non-functional requirements, user personas, design concepts, and technical specifications.

2. System Overview

The azure-vpn application will provide users with a secure and private internet browsing experience by encrypting their online traffic and masking their IP addresses. The system will include features such as:

• User authentication for secure access.
• A wide selection of VPN servers across multiple regions.
• High-speed connections with minimal latency.
• A user-friendly interface for managing connections and settings.
• Advanced security protocols to ensure data privacy.

The application will be available on both web and mobile platforms, ensuring accessibility and convenience for users.

3. Functional Requirements

• As a User, I should be able to create an account and log in securely.
• As a User, I should be able to select a VPN server from a list of available regions.
• As a User, I should be able to connect to and disconnect from the VPN with a single click.
• As a User, I should be able to view my connection status, including IP address and server location.
• As a User, I should be able to configure basic settings such as auto-connect and protocol preferences.
• As an Admin, I should be able to manage server configurations and monitor server performance.
• As an Admin, I should be able to view user activity logs for troubleshooting purposes (with privacy safeguards).

4. User Personas

4.1 Individual User

• Description: A general consumer looking for a secure and private browsing experience.
• Goals: Protect personal data, access geo-restricted content, and browse anonymously.
• Pain Points: Complex interfaces, slow connection speeds, and unreliable servers.

4.2 Business User

• Description: A small-to-medium business owner or employee requiring secure remote access to company resources.
• Goals: Ensure secure communication, protect sensitive business data, and maintain productivity.
• Pain Points: Lack of centralized control, limited server options, and inadequate encryption.

4.3 Admin

• Description: A system administrator responsible for managing the VPN infrastructure.
• Goals: Monitor server performance, ensure system reliability, and troubleshoot user issues.
• Pain Points: Limited visibility into system metrics and inefficient management tools.

5. Visuals Colors and Theme

Color Palette

• Background: #0A1F33 (Deep Navy Blue)
• Surface: #1E3A5F (Steel Blue)
• Text: #F5F7FA (Soft White)
• Accent: #4CAF50 (Emerald Green)
• Muted Tones: #A3B4C4 (Muted Gray-Blue)

This palette reflects a professional and secure aesthetic, emphasizing trust and reliability while maintaining a modern and sleek appearance.

6. Signature Design Concept

The azure-vpn homepage will feature an interactive globe visualization.

• Design Details:

  • A 3D rotating globe will dominate the center of the screen, with glowing markers indicating available VPN server locations.
  • Users can click on a marker to view server details and connect directly.
  • The globe will have smooth animations, with transitions between day and night modes based on the user's local time.
  • Hovering over a server marker will display a tooltip with server stats (e.g., latency, load).

• Micro-Interactions:

  • When a user connects to a server, the globe will zoom in on the selected region, and a glowing connection line will animate from the user's location to the server.
  • Subtle particle effects will indicate encrypted data flow.

This design will create an engaging and memorable first impression, reinforcing the application's focus on global connectivity and security.

7. Non-Functional Requirements

• The system must support at least 10,000 concurrent users without performance degradation.
• The VPN connection should maintain a latency of less than 50ms for local servers and 150ms for international servers.
• The application must comply with GDPR and local data protection regulations in Pakistan.
• The system should achieve 99.9% uptime, with minimal downtime for maintenance.
• The user interface must be responsive and accessible on both desktop and mobile devices.

8. Tech Stack

Frontend

• React for Web
• React Native for Mobile

Backend

• Python
• FastAPI

Database

• MySQL (with Alembic for migrations)

AI Tools

• GPT 5.4 for user-friendly responses
• Litellm for LLM Routing

Orchestration

• Docker
• Kubernetes

9. Assumptions and Constraints

• The application will primarily target users in Pakistan but will support international server connections.
• The system will rely on third-party VPN server providers for infrastructure.
• User activity logs will be anonymized to ensure privacy compliance.
• The application will support English as the default language, with the option to add Urdu in future updates.
