Functions

This section describes the main functions of CAE. You can check if a certain function is available in a region on the console.

Component Management

An application component implements a service feature of an application. It is in the form of code or software package and can be deployed independently. CAE manages application components developed.

You can deploy components in the current environment and application by deploying code sources, software packages, or image packages.

  • Deploying code sources: Use open-source code repositories or Huawei Cloud services, such as CodeArts, GitHub, and GitCode, to upload code to code repositories.
  • Deploying software packages: Upload a software package to the software release repository using CodeArts, upload a software package to an OBS bucket using Object Storage Service (OBS), or upload a software package to a repository using GitHub artifact.
  • Deploying an image package: Upload an image package to an image repository using SoftWare Repository for Container (SWR).

Instance Management

After a component is deployed, you can view the instance information and log in to the container through CloudShell.

Component Configuration

After a component is deployed, you can configure RDS for data interaction and CSE for microservice management and governance, and configure environment variables, access modes, AS policies, cloud storage mounting, health check, lifecycle, log collection, performance management, and custom metrics for components.

Component Monitoring and Logs

After a component is deployed, you can monitor instances of the component from multiple dimensions to learn the real-time running status of the component. In addition, you can search for logs and events on the GUI and view alarms to quickly locate faults.

  • Component events: Display events that occur during component deployment and running.
  • Component monitoring: Provides visualized real-time monitoring of CPU usage, uplink and downlink speeds (BPS), uplink and downlink rates (PPS), file system write/read rate, and memory usage.
  • Component logs: Provide instance-level running logs to help locate faults.
  • URL monitoring: After URL log monitoring is enabled, CAE reports URL routing logs to LTS. You can monitor URL logs of application components using LTS.

System Settings

You can configure environments and global settings, including cloud storage authorization, domain name configuration, certificate configuration, start/stop policy configuration, system network configuration, monitoring system configuration, compute resource pool configuration, source code repository authorization, event notification rules, and credential configuration.
