Azure Arc enabled Kubernetes


What does “Arc-enabled Kubernetes” mean? it means a Kubernetes Cluster that the Azure Arc Agent has been installed on.

Should an instance of Azure Arc be provisioned? No, Azure Arc is a global service.

What about data security? very good question! I’ll explain it below. Because first, you have to know how Azure Arc works.

How does Azure Arc work?

  • We use az-cli to install the Azure Arc Agent on a Kubernetes Cluster.
  • This command asks for an Azure location. This location is where the metadata of the cluster will be saved.
  • After the Agent has been installed a metadata object of your cluster will be seen on the Azure Portal in Azure Arc Service. Sometimes this metadata object is called a projected cluster.
  • This object only represents the connected cluster to Azure Arc and nothing more.

When should Arc be used?

In the following scenarios we can use Azure Arc.

  • You have an application that must be released in different and several cloud environments such as AWS, Azure, GCP, and On-Premises. And your company is responsible for their maintenance and monitoring.
  • You have several K8s Cluster and you have to work with multiple kube-config. Azure Arc can be a solution to get rid of working with multiple kube config contexts or logging in to different environments.
