System Architecture

Enterprise RAG for private intelligence

ISA-RAG uses a modular, service-oriented architecture for secure document ingestion, retrieval and governed AI responses. This page shows the architecture at a high level; authenticated users can inspect the deployment details.

Data Flow

End-to-end flow from knowledge ingestion to retrieval-augmented response generation.

1
Data Sources PDFs, docs, code and external knowledge inputs
2
Ingestion & Chunking Parsing, cleaning and splitting into semantic chunks
3
Embedding & Indexing Vector embeddings stored in a searchable index
4
User Query Natural language question from client apps
5
Retrieval Top-K semantic search over vector database
6
LLM Generation Context + prompt → grounded, cited response

Controlled access

Requests pass through an authenticated access layer before reaching internal services.

Ingestion pipeline

Documents are parsed, normalized, embedded and indexed for retrieval.

Encrypted end-to-end

Transport encryption and managed secrets protect system boundaries.

Architecture Layers

Access & Governance

A controlled entry layer authenticates requests, applies policy and routes traffic to internal capabilities.

Document Intelligence

Uploaded knowledge is normalized into searchable units while preserving metadata required for grounded answers.

hub

Retrieval & Reasoning

The assistant retrieves relevant context before generation so responses can stay aligned to the approved corpus.

Operational Controls

The platform is designed around isolated services, encrypted transport, observability and repeatable deployment.

Deployment Options

ISA-RAG can run in private infrastructure or cloud-native environments. Public documentation intentionally avoids exposing runtime topology, exact network configuration and sizing details.

Private infrastructure

Self-managed deployment

Suitable for organizations that need tight control over data locality, identity integration and network boundaries.

Cloud-native

Managed platform deployment

Suitable for teams that prefer managed databases, elastic compute and cloud-native operations while preserving least-privilege design.
