#Features

#Traffic Management Architecture

• Dual-layer Gateway Design (Tier1 + Tier2)
  Implements Tier1 gateway for external traffic routing management and Tier2 transparent proxy for service-level routing rule execution, resolving routing rule conflicts between gateway and service layers while maintaining policy consistency.

• Protocol Support
  Supports HTTP/1.1, HTTP/2, gRPC and WebSocket protocols for external service exposure, adapting to various modern application communication requirements.

• Dynamic Routing
  Supports weight-based and header-based traffic routing for A/B testing and canary deployments.

• Traffic Mirroring
  Replicates production traffic to staging environments for safe testing without impacting live users.

• Request Retries
  Configures automatic retries for failed requests with customizable retry conditions and backoff policies.

#Security & Access Control

• TLS Termination
  Provides SSL/TLS certificate management capabilities, supporting HTTPS encrypted access and certificate automatic rotation for north-south traffic.

• Cross-cluster Traffic Management
  Enables unified management of external access traffic across multiple clusters through gateway instance groups, supporting centralized certificate and routing policy configuration.

#Service Governance Integration

• Canary Release Support
  Implements service-level canary release strategies through Tier2 proxy, allowing gray traffic rules configured for backend services to take effect on ingress gateway traffic.

• Routing Policy Synchronization
  Automatically synchronizes service routing rules (timeout retry, traffic mirroring, etc.) to gateway traffic through dual-layer architecture design, maintaining policy consistency.

#Resilience & Fault Handling

• Circuit Breaking
  Automatically blocks requests to overloaded services based on error thresholds and latency metrics.

• Fault Injection
  Simulates service failures (HTTP errors, delays) to validate system fault tolerance and recovery workflows.

• Timeout Control
  Sets service-level timeout thresholds to prevent cascading failures and improve system responsiveness.

#Observability & Monitoring

• Real-time Monitoring
  Provides QPS, success rate, latency and other core metrics monitoring for gateway instances, supporting custom monitoring dashboards and alert policies.

• Access Log Analysis
  Records complete HTTP request logs including source IP, request method, response code and latency, supporting log query and traffic analysis.

#Deployment Flexibility

• Cross-cloud Deployment
  Supports deployment of gateway instances across multiple cloud platforms (AWS, Azure, private cloud), achieving unified management of hybrid cloud traffic through instance groups.

• Horizontal Scaling
  Enables dynamic scaling of gateway instances based on traffic load, supporting both manual scaling and HPA-based automatic scaling strategies.
