Container Service for Kubernetes:Manage clusters across cloud platforms and accounts with ACK One Fleet

Use cases

• Cross-account cluster management: Manage ACK clusters from different Alibaba Cloud accounts in a single Fleet instance.

• Cross-platform cluster management: Manage Kubernetes clusters on other clouds or on-premises alongside Alibaba Cloud clusters.

Fleet instance capabilities

After connecting your clusters, you can:

• Manage clusters, compute resources, networks, storage, security, monitoring, logs, jobs, applications, and traffic from a unified console and API.

• Auto-scale cloud resources for traffic fluctuations, or schedule scaling to optimize costs.

• Distribute applications, schedule jobs, and manage traffic across regions for a standardized cloud-native framework.

• Use the built-in backup center to protect applications and data, migrate workloads across regions, and deploy across servers for redundancy.

• Deploy Alibaba Cloud-verified components in large-scale Kubernetes environments to improve security, scheduling, AI computing, and big data computing.

Architecture

Prerequisites

Before you begin:

• External clusters are connected through a registered cluster in the same Alibaba Cloud account as the Fleet instance.

• The registered cluster is in the same region and virtual private cloud (VPC) as the Fleet instance for API server connectivity.

• If connected over the internet, the registered cluster can reach the Fleet instance publicly.

Connect clusters from a different Alibaba Cloud account

This example uses Account A's Fleet instance to manage two clusters:

• Cluster A — created in Account A

• Cluster B — created in Account B
