Core Components

Modular, independently deployable services built for scale and fault tolerance.

🌐

API Gateway & Edge Router

Traffic management, TLS termination, JWT validation, and intelligent routing to nearest regional cluster. Implements request deduplication and adaptive rate limiting.

Envoy Cloudflare OAuth2/OIDC
🗄️

Config Store & Versioning

Immutable configuration storage with append-only version history. Supports schema validation, environment branching, and atomic rollbacks via cryptographic hashing.

PostgreSQL JSONB SHA-256

Real-Time Sync Engine

Persistent WebSocket connections with fallback polling. Handles delta updates, conflict resolution, and connection recovery with exponential backoff.

WebSockets gRPC Streaming Delta Encoding
🔐

Encryption & Secrets Vault

End-to-end encryption for sensitive values. Integrates with KMS/HSM for key rotation. Field-level encryption with client-side decryption keys.

AES-256-GCM AWS KMS HashiCorp Vault
📡

Event Bus & Pub/Sub

Decouples configuration updates from client delivery. Ensures exactly-once processing with idempotency keys and dead-letter queues for failed deliveries.

Apache Kafka SQS Exactly-Once
📊

Observability Stack

Full-distributed tracing, structured logging, and real-time metrics. Custom dashboards for config drift detection, latency percentiles, and cache hit ratios.

OpenTelemetry Grafana Elasticsearch

Configuration Update Lifecycle

How a configuration change propagates from admin dashboard to client applications.

01

Submission & Validation

Admin submits JSON payload via REST API. Schema validator checks against JSON Schema v7 rules. Invalid payloads are rejected before entering the pipeline.

02

Versioning & Encryption

Validated config is hashed, versioned (vN+1), and sensitive fields are encrypted using envelope encryption. Immutable record is committed to PostgreSQL.

03

Event Publication & Cache Invalidation

Change event is published to Kafka. Redis cache keys are invalidated asynchronously. CDN edge nodes receive purge signals for stale configuration bundles.

04

WebSocket Fan-out & Client Delivery

Sync engine pushes delta updates over persistent connections. Clients apply updates atomically. Fallback HTTP polling ensures delivery for constrained networks.

05

Acknowledgment & Audit

Clients send acknowledgment receipts. Audit trail is updated with propagation timestamps, success rates, and client fingerprint metadata for compliance.
