What is KubeEdge

The KubeEdge mission

Our goal is to make an open platform to enable Edge computing, extending native containerized application orchestration capabilities to hosts at Edge. which built upon kubernetes and provides fundamental infrastructure support for network, app.deployment and metadata synchronization between cloud and edge. It also supports MQTT and allows developers to author customer logic and enable resource constraint devices communication at Edge. Kubeedge is the open platform to enable Edge computing. The advantages of Kubeedge include mainly:

• Edge Computing

  With business logic running at Edge, volumes of data can be secured & processed locally. It reduces the bandwidth request between Edge and Cloud; increases the response speak; and protects customers’ data privacy.

• Simplify development

  Developers can write regular http or mqtt based applications; containerize and run anywhere at Edge or Cloud.

• Kubernetes-native support

  With KubeEdge, users can orchestrate apps, manage devices and monitor app/device status against Edge nodes like a normal K8s cluster in the Cloud.

• Abundant applications

  You can easily get and deploy complicated machine learning, image recognition, event processing and other high level applications to your Edge side.

• And so on

What is KubeEdge?

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. It is built upon kubernetes and provides fundamental infrastructure support for network, app. deployment and metadata synchronization between cloud and edge.

Workflow

The basic workflow is:

• Make sure some basically tool in your Env, such as mosquitto and docker.
• Download the Kubeedge scripts and configuration files.
• Customize the configuration.
• Run mosquitto and Kubeedge binary to your chosen environment.

You adapt the configuration to choose the platforms and services that you want to use for your environment: certfile, keyfile, and so on.

Components

KubeEdge is composed of these components:

• Edged: Edged is an agent running on edge node for managing user’s application.
• EdgeHub: EdgeHub is a web socket client, which is responsible for interacting with Huawei Cloud IEF service, including sync cloud side resources update, report edged side host and device status changes.
• EventBus: EventBus is a MQTT client to interact with MQTT server(mosquitto), offer subscribe and publish capability to other components.
• DeviceTwin: DeviceTwin is responsible for storing device status and syncing device status to the cloud. It also provides query interfaces for applications.
• MetaManager: MetaManager is the message processor and between edged and edgehub. It’s also responsible for storing/retrieving metadata to/from a lightweight database(SQLite).
