Sermant is a CNCF Sandbox proxyless service mesh built on Java bytecode enhancement (JavaAgent) technology. It adds service governance capabilities to Java microservice applications without code changes, with a plugin ecosystem for extending governance features.

Use cases

• add service mesh governance to Java microservices without sidecar proxies
• instrument Spring Cloud or Dubbo applications without modifying source code
• implement traffic management, load balancing, and fault injection via JavaAgent
• build custom service governance plugins with a plugin development framework
• reduce latency and resource overhead compared to proxy-based service meshes
• dynamically configure governance rules for running microservices

When to choose

• you run large-scale Java microservices (Spring Cloud, Dubbo) and want proxyless service governance
• you cannot modify application source code but need mesh-like capabilities
• you want to avoid sidecar proxy latency and resource costs
• you need a pluggable, extensible bytecode-enhancement framework for governance features

When to avoid

• your services are polyglot and not JVM-based
• you prefer a mature full-featured mesh like Istio with sidecars
• you need governance for non-Java workloads
• you want a turnkey product rather than a framework requiring plugin development
