System Architecture
Technical blueprint of FlowCMS's headless, API-first infrastructure. Designed for horizontal scaling, multi-region deployment, and developer-centric workflows.
High-Level Architecture
FlowCMS utilizes a strictly decoupled headless architecture. All content is served via stateless REST & GraphQL endpoints. The edge layer handles caching, DDoS protection, and JWT validation before requests hit the core services. Multi-region active-active deployment ensures sub-50ms global latency.
Core Services
Content Engine API
GraphQL & REST endpoints for schema definition, content modeling, and version-controlled publishing. Supports real-time subscriptions via WebSockets.
Asset Pipeline Storage
Automated image/video optimization. WebP/AVIF conversion, CDN distribution, and metadata extraction. Stored in S3-compatible object storage.
AI Processing ML
Serverless inference cluster for auto-tagging, SEO scoring, content summarization, and multi-language translation using fine-tuned LLMs.
Auth & RBAC Security
JWT/OAuth2.0 with role-based access control. Supports SAML SSO, audit logging, IP allowlisting, and encrypted secret management.
Request Lifecycle
Client Request
Frontend application sends authenticated GraphQL/REST request to regional edge node.
Edge Validation
CDN validates JWT, applies rate limits, and checks cache layer. Cache hits return immediately.
Gateway Routing
API Gateway decrypts request, resolves tenant ID, and routes to appropriate microservice instance.
Service Execution
Content service queries PostgreSQL + Redis cache. AI hooks trigger asynchronously if configured.
Response & Cache
Payload is serialized, edge-cached with TTL, and returned. Webhooks fire for mutations.
API Schema Example
query { content(type: "blog_post", limit: 10) { id title slug status publishedAt }
}
