Anthos- Hybrid & MultiCloud Management

Let’s take a look at the key components of Anthos:

• Anthos Control Plane: This component is the meta control plane of Anthos. It’s responsible for managing the lifecycle of managed clusters and the registration and un-registration of external, unmanaged clusters. Anthos exposes the API for this through the Hub and Connect services.

• Anthos Service Mesh: This component is a commercially available implementation of Istio service mesh that’s optimized for Anthos. It delivers three capabilities – 1) secure communication among microservices, 2) Network and routing policies, and 3) observability.

• Anthos Config Management: This component based on GitOps enables a centralized mechanism to push deployments, configuration, and policies to all the participating clusters — both managed and unmanaged. A centrally accessible Git repository acts as a single source of truth for all the clusters. An Anthos Config Management agent running in each cluster will monitor the change of state in a cluster. When deviated from what’s defined in the Git, the agent automatically applies the configuration which will bring the cluster back to the desired state.

• Cloud Run for Anthos: Cloud Run is a serverless and clusterless environment to run containers in GCP. It’s a layer above Knative that delivers an optimal developer experience to deploy and run containers without the need to launch a GKE cluster or define a pod specification. Cloud Run for Anthos brings the same developer experience to the managed clusters.

• Ingress for Anthos: This component routes the traffic to the microservices in conjunction with the Envoy proxy configured through Anthos Service Mesh. Ingress for Anthos becomes the entry point to access workloads running in Anthos clusters. It currently works only for workloads running in GKE clusters launched by Anthos.

• Kubernetes Apps On GCP Marketplace: This acts as the catalog for a variety of stateless and stateful workloads targeting Kubernetes. Customers can push a button to deploy applications from the marketplace in Anthos managed clusters irrespective of where they are provisioned.

will use kubectx tool , that allow to switch between different env as eks-aws,gke-gcp,metal-onprem

we need to register cluster

we will register aws eks as below

Before registering, we need to enable SA for Anthos as below

register cluster
