Enterprise Distributed Application Service (EDAS) supports the native Spring Cloud microservices framework. You can deploy applications in EDAS to use its enterprise grade features, such as application management, microservices governance, monitoring and alerting, and application diagnosis, without the need to modify code or add configurations. The microservices governance features include service query, canary release, outlier ejection, and graceful shutdown. The features of EDAS help you improve the stability and security of your applications.
Overview
Spring Cloud provides a series of standards and specifications to simplify application development. The standards and specifications cover service discovery, load balancing, circuit breaking, configuration management, Spring Cloud Stream, and Spring Cloud Bus. Based on the standards and specifications, Spring Cloud provides implementation components for service gateways, distributed tracing, security, distributed job scheduling, and distributed job coordination.
Popular Spring Cloud implementation components in the industry include Spring Cloud Netflix, Spring Cloud Consul, Spring Cloud Gateway, and Spring Cloud Sleuth. Open source Spring Cloud Alibaba that is developed by the middleware team of Alibaba Group is also a popular implementation component in the industry.
If you have developed applications by using Spring Cloud components, such as Spring Cloud Netflix and Spring Cloud Consul, you can deploy the applications to EDAS. The applications immediately run as expected, and you can manage the applications in EDAS. In addition, you can use the advanced monitoring features of EDAS, such as distributed tracing, monitoring and alerting, and application diagnosis, without the need to modify a line of code.
To use more service governance features of EDAS to manage your Spring Cloud applications, you can deploy the applications in EDAS to use the comprehensive microservices governance capabilities. You do not need to modify code or configurations.
