Layer Descriptions

API Gateway

The API gateway handles TLS termination, request routing, rate limiting, and Web Application Firewall (WAF) protections. Static assets are served through a CDN for optimal global performance.

Application Layer

The application layer exposes a RESTful API organized into domain modules. Each module handles a specific area of functionality (authentication, projects, billing, etc.) and delegates to the service layer for business logic.

Key characteristics:

Stateless request handling for horizontal scalability
JWT-based authentication with per-request validation
Role-based access control at project, environment, and resource levels
Input validation on all endpoints

Service Layer

The service layer contains all business logic, including subscription limit enforcement, permission checks, cost calculations, and integration orchestration. This layer is the boundary between the API and the data layer.

Database Layer

The platform uses a relational database with:

Primary instance for all write operations
Read replicas for query distribution
Encrypted storage for sensitive data (credentials, API tokens, SSH keys)
Automatic schema migrations managed as part of the deployment process

Message Broker and Workers

Long-running and scheduled operations are processed asynchronously through a message broker and worker pool:

Job Category	Description	Scheduling
Email delivery	Transactional emails (invitations, password resets, alerts)	On-demand
Billing synchronization	Payment and invoice data sync with Stripe	Every 15 minutes
Integration sync	Jira, monitoring, and cloud provider synchronization	5-30 minutes
Cloud discovery	Auto-discovery of cloud resources from connected accounts	On-demand
Import/Export	Asynchronous processing of bulk data operations	On-demand
Cost calculations	Provider pricing updates and cost estimation	Periodic

Workers are independently scalable to handle varying workloads without impacting API response times.

Security Architecture

Encryption

Layer	Protection
Transport	TLS 1.3 for all HTTP traffic
Database	AES-256 encryption at rest
Secrets	Dedicated encryption for stored credentials (SSH keys, API tokens, integration secrets)
Passwords	One-way hashing with industry-standard algorithms
Sessions	Cryptographically signed JWT tokens with configurable expiration

Access Control

The platform implements multi-level access control:

Authentication: JWT tokens or API keys required for all API access
Project-level: Owner and Member roles determine project-wide permissions
Environment-level: Administrator, Manager, and Viewer roles for granular environment access
Resource-level: Per-service access grants for project-local users
Admin-level: Separate authentication layer for administrative operations

Audit Trail

All significant actions are recorded in a tamper-resistant audit log, including:

Authentication events (login, logout, failed attempts, 2FA changes)
Resource lifecycle events (create, update, delete)
Permission and role changes
Data export and import operations

Deployment Topology

Hosted (SaaS)

The hosted platform runs on a high-availability infrastructure:

Multiple availability zones for resilience against datacenter failures
Auto-scaling application instances based on request volume
Clustered message broker with mirrored queues for job reliability
Database replication with automated failover
CDN for global static asset delivery
Automated backups with point-in-time recovery

On-Premise (Enterprise+)

Enterprise+ customers can deploy the full platform on their own infrastructure. The on-premise deployment mirrors the hosted topology with customer-managed components. See the Enterprise Deployment guide for details.

Regional Deployments

Enterprise customers can specify data residency requirements:

US region (default)
EU region for GDPR compliance
Custom region for specific regulatory needs (Enterprise+)

Monitoring and Observability

The platform exposes health and metrics endpoints:

Health check: Quick liveness and readiness verification
Detailed health: Component-level status (database, message broker, integrations)
Metrics: Request rates, latencies, error rates, and queue depths

These endpoints support integration with your existing monitoring stack (Prometheus, Datadog, etc.).
