ACK Edge supports managing rich cloud and on-premises node resources. For complex edge network environments, ACK Edge provides strong edge autonomy and offline O&M to keep workloads running stably. This topic explains how to use ACK Edge node management capabilities.ACK Edge clusters with autonomy and offline maintenance for complex network environments.
Supported node types
Cloud node types
For hybrid cloud deployment, manage Elastic Compute Service (ECS) nodes through cloud node pools in ACK Edge clusters to leverage cloud elasticity, storage, and networking. Cloud nodes in ACK Edge clusters offer node management capabilities that are consistent with those in the ACK managed Pro cluster. See Node management.
Edge node types
-
ENS instances: Manage Edge Node Service (ENS) instances through edge node pools in ACK Edge clusters for geographically proximate access. See Manage ENS.
-
Cross-region ECS nodes: Like ACK managed Pro clusters, cloud node pools in ACK Edge clusters manage only ECS nodes within the same virtual private cloud (VPC). However, through edge node pools, ACK Edge clusters manage ECS nodes across different regions.
-
Other edge nodes: ACK Edge clusters manage IaaS resources outside Alibaba Cloud through the use of edge node pools, such as on-premises data centers, nodes from other cloud providers, and nodes in buildings, venues, factories, outlets, vehicles, and ships.
Supported node management operations
Cloud nodes
ACK Edge clusters offer the same cloud node management as ACK managed Pro clusters. See Node management.
Edge nodes
Basic management operations for edge nodes:
-
Add edge nodes to a specified node pool in the ACK Edge cluster. See Add edge nodes.
-
Manually upgrade edge nodes each time you upgrade the connected cluster, because they are not automatically updated. See Upgrade an edge node.
-
Remove nodes from the ACK Edge cluster. See Remove edge nodes.
Connect edge nodes to an ACK Edge cluster via public or private network. Unlike networks in a VPC, edge nodes face challenges due to network instability. ACK Edge provides autonomy and offline maintenance for continuous, stable service operation in complex edge network conditions.
-
Autonomy: During edge-cloud network disconnection, ACK Edge clusters keep applications running on edge nodes without eviction or migration. See Configure edge node autonomy.
-
Offline maintenance: When the network is disconnected, ACK Edge clusters allow for cluster changes without relying on the cloud control plane. See Offline O&M for edge nodes .
