Edge Node Service (ENS) is built on the edge nodes and networks of carriers. It provides elastic, distributed computing power close to end users worldwide. By processing data at the edge, ENS reduces response latency, the load on the central cloud, and overall costs. This topic describes how Alibaba Cloud ACK Edge clusters manage ENS nodes.
Background information
ACK Edge clusters provide container hosting capabilities for ENS. You can use ACK Edge clusters to centrally manage containerized ENS instances that are distributed across multiple regions and ISPs. They integrate with services such as ENS cloud disks and ENS edge load balancing to provide cloud-native storage and networking capabilities.
Notes on adding ENS nodes
Centralized management: ENS instances in multiple regions can connect to the API Server for management over the Internet or a leased line.
You can expose services across multiple regions using load balancing. For more information, see Expose services across multiple regions using ELB.
You can use the Container Storage Interface (CSI) plugin to manage dynamic and static persistent volumes on ENS cloud disks. For more information, see Use ENS cloud disks.
Steps to add ENS nodes
Create an edge node pool for the ACK Edge cluster. Ensure that all ENS instances added to the node pool are in the same Virtual Private Cloud (VPC) (ENS network). For more information, see Create an edge node pool.
Add ENS instances to the edge node pool in the ACK Edge cluster. For more information, see Add an edge node.
