| Billing Method |
Select a billing method for the CLB instance. In this example, Pay-As-You-Go is selected.
Note Only CLB instances that are billed on a pay-as-you-go basis support PrivateLink.
|
| Region and Zone |
Select the region and zone where you want to deploy the CLB instance. Make sure that
the CLB instance and the Elastic Compute Service (ECS) instances to be added to the
CLB instance are deployed in the same region.
|
| Zone Type |
Displays the type of zone that belongs to the specified region. A zone represents
a data center that contains a set of independent infrastructure resources. The infrastructure
resources (such as networks, power supply, and air-conditioning) in different zones
are independent of each other. Therefore, when the infrastructure resources in one
zone are down, the other zones are not affected. Each zone belongs to a specific region.
A region may contain one or more zones. Multi-zone CLB instances are available in
most regions.
- Single zone: The CLB instance is deployed in only one zone.
- Multi-zone: The CLB instance is deployed across two zones. The primary zone is used
to distribute network traffic by default. When the primary zone is down, the system
automatically switches to the secondary zone and continues to provide load balancing
services. This ensures high availability.
|
| Backup Zone |
Select the secondary zone of the CLB instance. By default, the secondary zone is used
to distribute traffic only when the primary zone is down.
|
| Instance Name |
Enter a name for the CLB instance.
The name must be 1 to 80 characters in length, and can contain letters and Chinese
characters, digits, hyphens (-), forward slashes (/), periods (.), and underscores (_).
|
| LoadBalancerSpec |
Select a specification for the CLB instance.
CLB instances with different specifications provide different features. For more information,
see SLB instance overview.
|
| Instance Type |
You can create an Internet-facing CLB instance or an internal-facing CLB instance
to meet your business requirements. The system allocates a public or private IP address
to the CLB instance based on the specified instance type. For more information, see
SLB instance overview.
- Public network: If you select this option, the system allocates a public IP address
to the CLB instance. You can access the CLB service over the Internet.
- Internal network: If you select this option, the system allocates a private IP address
to the CLB instance. You can access the CLB service only within networks of Alibaba
Cloud. You cannot access the CLB service over the Internet.
In this example, Internal network is selected.
Note Only Internal network CLB instances support the PrivateLink service.
