Feature description:

  • Access authentication: This feature prevents unauthorized users from accessing Nacos instances and keeps configurations confidential and secure.
  • Configuration encryption: This feature allows you to encrypt configurations by using Key Management Service (KMS) and ensures encrypted storage and transmission of configurations.
  • Traffic interworking between non-Java applications and Java applications: This feature enables traffic interworking between applications on Alibaba Cloud Service Mesh (ASM) instances and Java applications that are registered with MSE instances based on the service discovery feature.
  • Graceful migration: This feature allows you to migrate Spring Cloud applications and Dubbo applications from a self-managed registry to an MSE instance without the need to modify code or suspend services. Access to the applications during the migration is not affected.
