Enterprise Distributed Application Service (EDAS) provides a series of O&M features for applications. The features include the lifecycle management, application access management, application scaling, throttling and degradation, change records, event center, and log management.
Application O&M capabilities
|Lifecycle management||After you host an application to a Kubernetes cluster in EDAS, you can manage the lifecycle of the application in the EDAS console. For example, you can upgrade, roll back, scale out, scale in, start, stop, and delete the application. You can also manage the lifecycle of the application at a finer granularity by editing the YAML file. For more information, see Manage the application lifecycle.|
|Application access management||After you host an application to a Kubernetes cluster in EDAS, you may want to expose
service ports in the following two scenarios:
|Application scaling||If traffic fluctuates greatly, you can scale out or in applications by using manual or automatic scaling to increase or decrease the number of instances. This improves resource utilization and reduces the cost of application resources. For more information, see Manual scaling or Auto scaling.|
|Change record||If you have performed lifecycle actions on applications in the EDAS console, such as application deployment, startup, and scaling, you can go to the application details page to check the change status or go to the Change List page to view change records. For more information, see View application changes.|
|Event Center||The event center supports the following event sources: application change events of EDAS, alert events of Application Real-Time Monitoring Service (ARMS), 0-1 status events, such as deadlocks, out of memory (OOM), and application startup failures, microservice governance events of Microservice Engine (MSE), and events of Kubernetes clusters. If your application uses one of the related services, the event center automatically analyzes and displays the corresponding events in a unified manner. This provides an easy way for you to view and analyze the events. For more information, see Event center.|
|Log management||EDAS provides the log management feature.
