Alibaba Cloud ENS is built on a network of over 3,200 carrier-operated edge nodes, covering all provinces and carriers in the Chinese mainland and extending to more than 70 countries and regions worldwide. Globally, over 900 public cloud edge nodes are available. Capabilities vary between ENS nodes due to differences in their network architecture and hardware. The Capability Map is a tool that helps you find nodes that meet your specific requirements.
Why use the capability map
ENS capabilities are divided into universal and differentiated. Universal capabilities, such as security groups and key pairs, are available on all edge nodes by default. Differentiated capabilities vary by node. Use the Capability Map to find which nodes support a given capability.
The following capabilities are supported by all nodes by default: image, key pair, security group, VSwitch, and network ACL.
Use cases
Common scenarios:
-
Check capabilities of your current edge nodes to identify expansion opportunities.
-
Find edge nodes that support capabilities required for a planned deployment.
Procedure
-
Log on to the ENS console. In the left-side navigation pane, click Overview.
-
On the Overview page, click Capability Map.

Query capabilities by node
-
Basic query
-
On the Query Capabilities by Nodes tab, click Select a node in the upper-left corner to choose which nodes to query.
-
All ENS nodes are grouped by region. Select the required nodes and click OK to run the query.
-
-
Simplified display
-
Filter results by capability level to narrow your focus.
-
In the results section, click the filter icon
next to Primary Capability to filter by primary capabilities.NoteENS capabilities are organized into multiple levels. For example,
cloud diskis a primary capability, while an all-flash cloud disk is a secondary capability.Filterable primary capabilities include: compute instance, snapshot, cloud disk, Edge Object Storage (EOS), Edge NAS (ENAS), Storage Gateway, and Network. Select the capabilities you need and click OK.

Status indicators
The Query Capabilities by Nodes tab displays a capability matrix. The left column lists primary and secondary capabilities (compute instance, snapshot, cloud disk, EOS, ENAS, and Network). The right columns represent individual nodes. Use the All Nodes drop-down list to filter displayed nodes.

Query nodes by capability
-
Basic query
-
On the Capability Map page, click the Query Nodes by Capabilities tab.
-
In the filter box, select the capabilities to query. ENS lists nodes that support all selected capabilities. After choosing your deployment nodes, click Copy Selected Nodes in the upper-right corner to copy the node list.
After you select nodes, a Create instance shortcut appears at the bottom of the page for creating resources directly on those nodes.

Quick resource creation
If your selected nodes meet certain capability criteria, a More operations menu appears at the bottom of the page with shortcuts for creating resources without leaving the current page.
