Alibaba Cloud ENS is built on over 3,200 carrier edge nodes. It provides complete coverage for all provinces and carriers in the Chinese mainland and extends to over 70 key countries and regions outside China. More than 900 public cloud edge nodes are available worldwide. Because ENS nodes use different network architectures and devices, their supported capabilities vary. The capability map is a tool that helps you quickly find nodes that meet your needs. This topic describes the capability map feature.
Why use the capability map
ENS capabilities are divided into two types: general and specialized. General capabilities, such as security groups and key pairs, are supported by default on all edge nodes. Specialized capabilities are supported only on specific nodes. You can use the capability map to find which nodes support these specialized capabilities.
By default, all edge nodes support the following capabilities: images, key pairs, security groups, vSwitches, and network access control lists (ACLs).
Scenarios
The capability map is useful in the following scenarios:
You already use ENS on some edge nodes and want to know what other capabilities these nodes support. This information can help you decide whether to expand your business.
You know which capabilities your business needs and want to find which edge nodes support them before you begin deployment.
Procedure
Log on to the ENS console. In the navigation pane on the left, click Overview.
On the Overview page, click Capability Map.
Data metrics
View capabilities of an edge node
Basic query
On the Query Capabilities By Nodes tab, click Select A Node in the upper-left corner to select the nodes to query.
All ENS nodes are categorized by region. You can select the required nodes and then click OK to start the query.
Simplified display
You can also filter the results by capability level to focus on the products that you are interested in.
In the results section, click the
icon next to Primary Capability.NoteENS product capabilities are divided into multiple levels. For example, disk is a primary capability, and all-flash disk is a secondary capability.
Additional information
Status description
indicates that the node supports the ENS product capability.
indicates that the node does not support this capability. Contact your account manager.NoteSome available nodes may not be on your whitelist. If you cannot find a specific node when making a purchase, contact your account manager to have it added to your whitelist.
Page layout: Each node's support status appears in its own column. In the lower-right corner, set Columns Per Page to 6, 8, or 10 to best fit your screen width.
Find nodes that support a capability
Basic query
On the Capability Map page, click the Query Nodes By Capacities tab.
In the filter box, select the product capabilities that you want to query. ENS displays the nodes that support all the selected capabilities. Select the nodes where you want to deploy your services and click Copy Selected Nodes in the upper-right corner to copy the list of nodes to your clipboard.
Quickly create resources on nodes
If your selected nodes meet certain rules, the Recommended Actions section appears at the bottom. This section provides quick-creation cards for resources. You can select your target nodes from the query results and then create resources directly on these nodes to avoid navigating between pages.
When you select X86 Compute, VPC, and your required nodes, the Capability Map displays a Create X86 Compute Instance card. Click Create X86 Compute Instance in the lower-left corner to select a creation method.
Creating a Web Host
If you choose managed network creation, you are redirected to the ENS instance creation page. For more information, see Create an instance.
Self-built network creation
If you choose self-built network creation, this option creates an instance on a node that has an existing network. You are then redirected to the instance creation page. ENS pre-fills the required parameters, such as the self-built network and the node.
NoteENS automatically checks whether a VPC network exists on the selected node. If you have not created a network on the node, you must create one, refresh the page, and then retry. For more information, see Create and manage VPCs and vSwitches.
