Full features list:

• Non-intrusive Design: Zero code modification for Java Spring Cloud application migration, only small configuration update needed.
• Java Register/Discovery: Compatible with popular Java Spring Cloud ecosystem's Service register/discovery
  • Multiple tenants(namespace) Supporting multiple tenants' service registration, isolation between deferent tenants
  • Share (global) tenant Support share tenants, all services have visibility to the service registered in the global tenant.
  • Compatible
  • Be compatible with the eureka registry.
  • Be compatible with the consul registry.
  • Be compatible with the nacos registry.
  • Extensibility Support registering services with metadata.
• Resource Management: Rely on Kubernetes platform for CPU/Memory resources management.
• Traffic orchestration
  • Rich Routing Rules: exact path, path prefix, regular expression of the path, method, headers.
  • Traffic Splitting Coloring & Scheduling east-west and north-south traffic to configured services.
  • LoadBalance Support Round Robin, Weight Round Robin, Hash by Client IP Address, Hash by HTTP Headers.
• Resilience: Including Timeout/CircuitBreaker/Retryer/Limiter, completely follow sophisticated resilience design.
  • Resilience&Fault Tolerance
    • Circuit breaker: Temporarily blocks possible failures.
    • Rate limiter: Limits the rate of incoming requests.
    • Retryer: Repeats failed executions.
    • Time limiter: Limits the duration of execution.
  • Chaos engineering
  • Fault injection Working in progress.
  • Delay injection Working in progress.
• Observability:
  • Logs
  • Access Logs Generate HTTP access log for all request per service
  • Application log Automatically inject the tracing context into log data.
  • Tracing
