Resource management

Microservices namespace

EDAS uses microservices namespaces to provide isolated runtime environments, such as development, staging, and production environments. You can use microservices namespaces to isolate resources and services. This way, you can realize centralized management by using a single account.

Manage microservices namespaces in the EDAS console

ECS cluster management

EDAS allows you to create clusters, scale out clusters, and perform other management operations on clusters. You cannot manage ECS clusters that are purchased by EDAS.

• Manage ECS clusters

• Scale out an ECS cluster in the EDAS console

Kubernetes cluster management

EDAS allows you to import all types of Kubernetes clusters created in Container Service for Kubernetes (ACK), except ACK Serverless clusters.

• Overview

• Overview of application upgrades and rollbacks (applicable to Kubernetes clusters)

Hybrid cloud

EDAS allows you to deploy applications in hybrid cloud ECS clusters and provides complete solutions for the scale-out, networking, and centralized management of these clusters. You can connect Alibaba Finance Cloud ECS instances, servers from data centers, and servers from other cloud service providers by using Express Connect circuits, and add the instances and servers to hybrid cloud ECS clusters in EDAS. This way, you can deploy applications in these clusters and use application hosting capabilities that are provided by EDAS.

Create a hybrid cloud ECS cluster

Resource group

If you use your Alibaba Finance Cloud account to purchase resources and manage applications as a RAM user, you can manage account permissions by using resource groups. EDAS allows you to grant RAM users the permissions on a resource group. This way, each authorized RAM user can manage all the resources in the resource group.

Manage resource groups

Application deployment

• After you develop and test an application, you can create and deploy the application in an ECS cluster.

• After you create and deploy an application in EDAS, you may need to update the application. If an error occurs on the new application version after an update, you can roll back your application to an earlier version.

Application O&M

EDAS provides the following O&M features for applications:

• Application lifecycle management

• Server load balancing

• Change history

• Logs

Service authentication

EDAS supports access control on Spring Cloud and Dubbo applications by using service authentication. If a microservices application requires high security and you want to restrict access to it from other applications, you can authenticate the applications that call the microservices application. This ensures that only the applications that match the authentication rules can call the microservices application.

• Implement access control on Spring Cloud applications by using service authentication

• Implement access control of Dubbo applications through service authentication

Outlier ejection

In a microservices framework, service calls are affected if consumers cannot detect the exceptions on the application instances of a provider. This further affects the performance and even availability of the services provided by the consumers. The outlier ejection feature monitors the availability of application instances and dynamically adjusts the instances. This ensures successful service calls and improves the service stability and quality of service (QoS).

• Ensure the availability of Spring Cloud applications by using outlier ejection

• Ensure the availability of Dubbo applications by using outlier ejection
