Enterprise Distributed Application Service:Get started with EDAS

Last Updated:Jan 03, 2024

To help you experience Enterprise Distributed Application Service (EDAS), Quick Start shows you how to deploy microservice-oriented application demos based on Spring Cloud and Apache Dubbo (Dubbo for short) to different EDAS environments. Each deployment scenario can be completed within 30 minutes.

EDAS provides one to five pay-as-you-go application instances for free. If you have activated pay-as-you-go Standard Edition for EDAS and deploy no more than five application instances, you are not charged for using EDAS. However, you must pay for the Alibaba Cloud resources that you use to create Elastic Compute Service (ECS) and Server Load Balancer (SLB) instances until you release these resources.

Nacos is used as the registry for the application demo that is provided by EDAS. You can also create a registry or use Microservice Engine (MSE) to host another type of registry, such as Eureka or ZooKeeper, based on your requirements. Make sure that the registry and the environment in which applications are to be deployed are connected over a network. If this condition is met, you can deploy your applications to EDAS without modifying code and use the application management, microservices, and cloud-native PaaS platform capabilities of EDAS.

  • Default environment: the default ECS cluster in the default virtual private cloud (VPC) and default microservice namespace that are provided by EDAS. EDAS provides a default environment only for ECS clusters but not for Kubernetes clusters.

  • Custom environment: the ECS cluster or Kubernetes cluster that you create.
