Microservice Governance in Focus: What’s EDAS?

What Is EDAS?

Why Use EDAS?

The History of EDAS Microservice Support

Open Source, Commercialization, and Cloud-native

Difficulties in EDAS Microservice Governance

  • Difficulty 1: EDAS supports a variety of microservice frameworks, including Dubbo, Spring Cloud, and HSF.
  • Difficulty 2: There are multiple versions of each microservice framework:
  • For Dubbo, EDAS supports versions 2.5, 2.6, and 2.7.
  • For Spring Cloud, EDAS supports versions later than D.
  • Difficulty 3: Traditional service queries require access registries, but there are a large variety of registries that are used by users:
  • Zookeeper
  • Nacos
  • Eureka
  • Difficulty 4: EDAS supports two deployment modes:
  • ECS JAR package deployment
  • Kubernetes image deployment
  • Difficulty 5: We need to take the migration problems and transformation costs of existing users into account.

Implementing EDAS Microservice Enhancements


public class MicroServiceTransformer implements ClassFileTransformer {    @Override
public byte[] transform(ClassLoader loader, String className, Class<?> classBeingRedefined, ProtectionDomain protectionDomain, byte[] classfileBuffer) throws IllegalClassFormatException {
if ("org/apache/dubbo/config/ReferenceConfig".equals(className)) {
System.out.println("microservice improve");
return null;


public class MicroService {
public static void premain(String options, Instrumentation ins) {
ins.addTransformer(new MicroServiceTransformer());
