Assistant: Hello! How are you today?
User: Architectural Overview

The platform is designed as a set of decoupled microservices orchestrated via an API Gateway. This separates the user-facing application from the complex backend processes, including the AI/LLM interactions and the knowledge base management. We will use AWS services as a concrete example, but the principles are cloud-agnostic.

Component Breakdown

1. Frontend (User Interface)

Description: A modern Single-Page Application (SPA) that provides the entire user experience, including the use case selection, the chat window, the "Use Case Analysis Panel," the "Use Case Builder" wizard, and the final report dashboard.

Technology: React, Vue.js, or Angular.

Interaction: Communicates exclusively with the Backend via the API Gateway using REST or GraphQL APIs.

2. API Gateway

Description: The single, secure entry point for all requests from the frontend. It handles user authentication, authorization, rate limiting, and routes requests to the appropriate backend microservice.

Technology: Amazon API Gateway.

3. Backend Microservices

This is the core application logic, broken down into distinct services.

A. User & Project Service:

Purpose: Manages user accounts, project sessions, and the state of each ongoing analysis.

Interacts with: Relational Database (to store user/project data).

B. Document Ingestion Service:

Purpose: Handles the uploading of user documents (RFPs, Excel sheets). It places the raw file in Object Storage and sends a message to a queue for asynchronous processing.

Interacts with: Object Storage (S3), Message Queue (SQS).

C. RAG & Parsing Service (Asynchronous Worker):

Purpose: Listens for messages from the queue. When a new document arrives, it parses it. For unstructured docs (.pdf, .docx), it chunks the text, creates embeddings using an AI model, and stores them in the Vector Database. For structured docs (.xlsx, .csv), it parses the data and stores it in the Relational Database.

Interacts with: Message Queue, Object Storage, Vector DB, Relational DB, Embedding Model (e.g., from SageMaker).

D. Conversational AI Service (The Core Engine):

Purpose: Manages the entire user conversation. It receives user messages, consults the appropriate .mdand .json use case files from the Knowledge Base, retrieves relevant context from the Vector DB (RAG), and constructs the final prompt for the LLM.

Interacts with: API Gateway, LLM, Vector DB, Relational DB, Object Storage (to read use case files).

E. Use Case Builder Service:

Purpose: Powers the "Use Case Builder" wizard. It takes the user's input from the UI and generates the new .md and .json files, saving them into the Knowledge Base in Object Storage.

Interacts with: API Gateway, Object Storage.

F. Simulation & BOM Service:

Purpose: Handles the "Simulate" functionality. It runs complex queries against the structured Intel SKU and benchmark data stored in the Relational Database to find optimal hardware configurations. It also generates the final BOM.

Interacts with: API Gateway, Relational DB.

G. Report Generation Service:

Purpose: Takes the final, completed JSON object from the Conversational AI Service and generates the comprehensive 6-part report, potentially as a PDF or a rich HTML page.

Interacts with: API Gateway, Relational DB (for final data).

4. AI & LLM Layer

Description: This layer contains the core AI models. It can be a mix of third-party APIs and self-hosted models.

Components:

Large Language Model (LLM): The model that powers the conversation (e.g., OpenAI GPT-4, Anthropic Claude, or a fine-tuned model hosted on Amazon SageMaker).

Embedding Model: A smaller model used specifically by the RAG service to convert text chunks into vector embeddings.

5. Data & Knowledge Base Layer

Description: The persistent storage layer for the entire platform.

Components:

Object Storage (Amazon S3): The "source of truth." Stores all raw uploaded documents, and more importantly, the library of .md and .json use case files that define the AI's capabilities.

Relational Database (Amazon Aurora/PostgreSQL): Stores all structured data: user information, project state, the parsed Intel SKU catalog, and performance benchmarks.

Vector Database (Amazon OpenSearch, Pinecone, Chroma): Stores the embeddings of the unstructured documents, enabling fast semantic search for the RAG process.

Message Queue (Amazon SQS): Decouples the front-end upload action from the back-end processing, making the application responsive.
