Creating a VPC Endpoint Service

Scenarios

This section describes how to configure a private service into an interface VPC endpoint service.

Constraints

• VPC endpoint services are region-level resources. Select a region and project when you create such a service.
• Each tenant can create a maximum of 20 VPC endpoint services.
• The following private services can be configured into VPC endpoint services:
  • Elastic load balancer: Backend resources of this type suit services that receive high access traffic and demand high reliability and disaster recovery (DR) performance.
  • ECS: Backend resources of this type serve as servers.
  • BMS: Backend resources of this type serve as servers.
• One VPC endpoint service corresponds to only one backend resource.

Prerequisites

There is a load balancer in the VPC where you are going to create the VPC endpoint service.

Procedure

1. Go to the VPC endpoint service list page.
2. Click Create VPC Endpoint Service.

   The Create VPC Endpoint Service page is displayed.

3. Configure parameters by referring to Table 1.

   Table 1 Parameters for creating a VPC endpoint service

   Parameter	Description
   Region	Specifies the region where the VPC endpoint service is to be deployed. Resources in different regions cannot communicate with each other over an intranet. For lower latency and quicker access, select the nearest region.
   Name	This parameter is optional. Specifies the name of the VPC endpoint service. The name can contain a maximum of 16 characters, including letters, digits, underscores (_), and hyphens (-). If you do not enter a name, the system generates a name in {region}.{service_id} format. If you enter a name, the system generates a name in {region}.{Name}.{service_id} format.
   VPC	Specifies the VPC where the VPC endpoint service is to be deployed.
   Service Type	Specifies the type of the VPC endpoint service. The type can only be Interface.
   Connection Approval	Specifies whether the connection between a VPC endpoint and a VPC endpoint service requires approval from the owner of the VPC endpoint service. You can enable or disable Connection Approval. When Connection Approval is enabled, any VPC endpoint for connecting to the VPC endpoint service needs to be approved. For details, see Managing Connections of a VPC Endpoint Service.
   Port Mapping	Specifies the protocol and ports used for communications between the VPC endpoint service and a VPC endpoint. The protocol is TCP. Service Port: provided by the backend resource bound to the VPC endpoint service. Terminal Port: provided by the VPC endpoint, allowing you to access the VPC endpoint service. The service and terminal port numbers range from 1 to 65535. A maximum of 50 port mappings can be added at a time. NOTE: Accessing a VPC endpoint service from a VPC endpoint is to access the service port from the associated terminal port.
   Backend Resource Type	Specifies the backend resource that provides services to be accessed. The following backend resource types are supported: Elastic load balancer: Backend resources of this type suit services that receive high access traffic and demand high reliability and disaster recovery (DR) performance. ECS: Backend resources of this type serve as servers. BMS: Backend resources of this type serve as servers. In this example, select Elastic load balancer. NOTE: For the security group associated with the backend resource configured for the VPC endpoint service, add an inbound rule, with Source set to 198.19.128.0/17. For details, see Adding a Security Group Rule in the Virtual Private Cloud User Guide. If you configure a load balancer as the backend resource for the VPC endpoint service, and enable access control for the listener associated with the load balancer, ensure to allow traffic from 198.19.128.0/17.
   Load Balancer	When Backend Resource Type is set to Elastic load balancer, select the load balancer that provides services from the drop-down list. NOTE: If an elastic load balancer is used as the backend resource, the source IP address received by the VPC endpoint service is not the real address of the client.
   ECS List	This parameter is available when you select ECS for Backend Resource Type. Select an ECS from the ECS list.
   BMS List	This parameter is available when you select BMS for Backend Resource Type. Select a BMS from the BMS list. NOTE: The BMS type will be discarded. The ELB type is recommended.
   Tag	This parameter is optional. Specifies the VPC endpoint service tag, which consists of a key and a value. You can add up to 20 tags to each VPC endpoint service. Tag keys and values must meet requirements listed in Table 2. NOTE: If a predefined tag has been created on TMS, you can directly select the corresponding tag key and value. For details about predefined tags, see Predefined Tag Overview.
   Description	Provides supplementary information about the VPC endpoint service.

   Table 2 Tag requirements for VPC endpoint services

   Parameter	Requirement
   Tag key	Cannot be left blank. Must be unique for each resource. Can contain a maximum of 36 characters. Can contain only letters, digits, hyphens (-), and underscores (_).
   Tag value	Cannot be left blank. Can contain a maximum of 43 characters. Can contain only letters, digits, hyphens (-), and underscores (_).
