This document outlines the comprehensive technical architecture for "PantheraConnect," a highly scalable and resilient platform designed to facilitate collaboration and communication. This architecture emphasizes modularity, cloud-native principles, and robust security, providing a solid foundation for future growth and feature development.
This deliverable provides a detailed technical architecture design for PantheraConnect, encompassing system diagrams, API specifications, database schemas, infrastructure plans, and scalability recommendations. The proposed architecture leverages a modern microservices-oriented approach, containerization, and cloud-native services (AWS-centric) to ensure high availability, performance, and maintainability. The design focuses on a clear separation of concerns, robust data management, and a secure, scalable deployment environment.
PantheraConnect is envisioned as a platform that enables users to create profiles, publish content (posts, articles), comment on others' content, and interact through various social features. It will support real-time notifications, media uploads, and a personalized user experience.
Core Components:

Prepared For: PantheraHive Stakeholders
This document outlines the comprehensive technical architecture for the "PantheraHive Project Management System" (PPMS). The proposed architecture is designed to be scalable, secure, highly available, and maintainable, leveraging modern cloud-native principles and best practices. It details the system's components, their interactions, data models, infrastructure plans, and strategies for ensuring future growth and resilience. This design aims to provide a robust foundation for a high-performance, user-friendly project management solution.
The PantheraHive Project Management System will facilitate efficient project planning, task management, collaboration, and reporting for teams.
2.1. Key Functional Requirements:
2.2. Key Non-Functional Requirements:
The PPMS architecture follows a microservices pattern, orchestrated within a cloud environment, providing flexibility and independent scaling.

4.1. Frontend Architecture
* State Management: React Query for data fetching and caching, Zustand/Jotai for global state.
* Styling: Tailwind CSS or Styled Components.
* Deployment: Static assets served from AWS S3 via CloudFront CDN.
4.2. Backend Services Architecture (Microservices)
Each microservice is an independently deployable, scalable unit.
* User Service: Manages user profiles, authentication (integrates with Auth0/Cognito), roles, and permissions.
* Project Service: Handles project creation, updates, deletion, and retrieval.
* Task Service: Manages task lifecycle (create, assign, status updates, dependencies).
* Collaboration Service: Manages comments, file attachments, and activity feeds.
* Notification Service: Sends real-time and email notifications (integrates with SQS/SNS).
* Reporting Service: Generates analytical reports based on project and task data.
* Synchronous: RESTful APIs for direct service-to-service communication or via API Gateway.
* Asynchronous: Message queues (AWS SQS/SNS) for event-driven communication (e.g., "Task Updated" event triggers Notification Service).
4.3. API Gateway
4.4. Database Layer
4.5. Message Queue/Broker
* Asynchronous task processing (e.g., sending email notifications, generating reports).
* Decoupling services.
* Event-driven architectures (e.g., "Task Created" event published to SNS, subscribed by Notification Service).
4.6. Authentication & Authorization
All APIs will adhere to RESTful principles and be documented using OpenAPI (Swagger) specification. This ensures clear contracts between frontend and backend, and between microservices.
