Architecture Overview

Built for
Enterprise Scale

AetherFlow processes millions of documents reliably because reliability is an architectural property — not a feature bolted on after the fact. Here's how the platform is built.

Platform Architecture

Six layers. Every one hardened for production.

From browser to database, each layer of AetherFlow is purpose-built for large-scale content migration — not adapted from a generic SaaS template.

01

Client Layer

React / Next.js
  • React 18 + Next.js dashboard
  • Flow Builder — ReactFlow canvas for drag-and-drop migration design
  • Real-time SSE monitoring — per-document progress streaming
  • MetaMap™ visual field mapping editor
  • Role-based views — Admin, Operator, Auditor
02

API Gateway

Express.js
  • Express.js — 119+ REST endpoints
  • JWT + Supabase dual authentication
  • Per-route rate limiting and request validation
  • SSE endpoint for real-time event streaming to dashboard
  • Webhook delivery for external integrations
03

Event Pipeline

Redis Streams
  • Redis Streams — 10 named streams, 9 consumer groups
  • Pub/sub notifications for real-time dashboard updates
  • Dead Letter Queue (DLQ) with Slack/email alerting
  • Flow state machine — PENDING → RUNNING → PAUSED → COMPLETE
  • Event replay for debugging and audit
04

Processing Engine

.NET Workers
  • Multi-agent .NET workers — concurrent document processing
  • Adaptive rate limiting — backs off under target ECM load
  • Checkpoint/resume — zero re-work on interruption
  • Concurrent backfill with configurable parallelism
  • Per-batch retry with exponential backoff
05

Connector Framework

CDK Framework
  • CDK — Connector Development Kit for extensibility
  • Descriptor-driven UI — connectors define their own config screens
  • 6 production connectors: OnBase, Square9, FileHold, SQL Server, SharePoint, OneDrive
  • Bidirectional support — any connector can be source or target
  • Connection profile encryption with per-tenant keys
06

Data Layer

PostgreSQL / Supabase
  • PostgreSQL via Supabase — managed, globally replicated
  • Row-Level Security on all tables — tenant isolation enforced at DB layer
  • AES-256 encryption for connection profiles
  • Audit log table — immutable append-only migration history
  • Point-in-time recovery for data protection
Migration Flow

How a Migration Runs

Six stages from configuration to verified completion. Every stage is checkpointed, retryable, and fully logged.

01
Configure

Connect source + target, select tables or document types

02
Validate

Schema compatibility check, MetaMap™ field mapping, test sample

03
Stream

Paginated read from source via CDK connector

04
Transform

Apply MetaMap™ transforms, type coercions, lookups

05
Load

Write to target with retry logic and DLQ isolation

06
Verify

Automated reconciliation — count, checksum, compliance report

Every stage writes a checkpoint. Any failure restarts from the last committed point.
Technical Differentiators

Why architecture-first matters for migrations

Every design decision in AetherFlow reflects a real failure mode we encountered running migrations for enterprise clients. These aren't marketing claims — they're battle scars.

Zero-downtime migration

Incremental sync + high-water-mark tracking means your source system stays live throughout. Final cutover is measured in minutes, not days.

Fault tolerance by design

Auto-retry with exponential backoff, checkpoint/resume at every stage, and DLQ isolation for failed records. Transient failures never become permanent data loss.

Horizontal scaling

Multi-agent architecture with load-based routing. Add more workers to increase throughput — no single-threaded bottlenecks anywhere in the stack.

Security by default

SOC 2-aligned practices, RLS on every table, AES-256 credential encryption, JWT + Supabase dual auth, and full audit logging. Security is architecture, not afterthought.

Performance

Sub-200ms API responses.
Concurrent flows.

The dashboard stays responsive regardless of how many migration flows are active. The API layer is decoupled from the processing engine — a busy migration never starves the UI or blocks new flow starts.

  • Sub-200ms P95 API response time target
  • SSE streaming for zero-polling real-time UI updates
  • Multiple concurrent flows — no global lock anywhere
  • Redis Streams decouple ingestion rate from processing rate
  • Worker pool auto-scales within configured concurrency limits
  • Adaptive backpressure prevents ECM target overload

AES-256 encryption

All connection profiles and credentials encrypted at rest with per-tenant keys.

Row-Level Security

Supabase RLS enforces tenant isolation at the database layer — not just application logic.

Immutable audit log

Every migration action is written to an append-only audit table for compliance review.

SOC 2-aligned practices

Access controls, change management, and monitoring aligned to SOC 2 Type II criteria.
