How do I improve cross-region access experience of cloud computers? - Elastic Desktop Service

If end users need to access Elastic Desktop Service (EDS) resources across regions, such as accessing cloud computers deployed in the Chinese mainland from an overseas region, you can configure a custom domain name for the office network in which the cloud computers reside. You can use the custom domain name to replace the default gateway domain name of the deployment region. Network acceleration services such as Global Accelerator (GA) are used to speed up resource access and improve user experience. This topic describes how to configure custom access domain names for office networks to improve user experience of accessing cloud computers across regions. In this topic, GA is used as an example.

Background information

In this topic, cloud computers deployed in the China (Guangzhou) region and accessed from the Philippines (Manila) region are used as examples.

Applicable scope

Terminals: Alibaba Cloud Workspace terminals, excluding the Alibaba Cloud Workspace client for web
Regions: China (Fuzhou - Local Region), China (Guangzhou), China (Hong Kong), Philippines (Manila), Thailand (Bangkok), US (Silicon Valley), and Germany (Frankfurt)

If the preceding regions cannot meet your business requirements, submit a ticket.

Billing

You are not charged for configuring custom access domain names for office networks. However, you are charged if you use GA. For more information, see Billing Overview.

Step 1: Create a GA instance

Before you configure custom access domain names for office networks, go to the GA console to create a GA instance.

Log on to the GA console.
In the left-side navigation pane, choose Standard Instance > Instances.
On the Instances page, click Create Standard Pay-as-you-go Instance or Create Standard Subscription Instance based on your business requirements.
In this topic, a standard pay-as-you-go instance is used as an example.

On the wizard page, configure the parameters described in the following table and click Next to go to the subsequent steps. For parameters that are not listed in the table, use the default values.

Parameter	Description	Example
Basic Instance Configuration step
GA Instance Name	Enter a name for the GA instance.	ga-for-office-network
Instance Billing Method	You are charged instance fees, Capacity Unit (CU) fees, and data transfer fees for pay-as-you-go standard Global Accelerator instances. For more information about instance fees and CU fees, see Billing of pay-as-you-go GA instances. For more information about data transfer fees, see Pay-by-data-transfer.	Select Pay-As-You-Go.
Terms of Service	The first time you activate the service, read and agree to the terms of service.	Read and agree to the terms of service.
Configure Acceleration Area step
Acceleration Area	Select a region that is close to your end users. Select one or more regions where you want to accelerate network access and click Add.	Philippines (Manila)
Configure listeners step
Protocol	Select a protocol for a listener. Cloud computers use TCP and UDP. In this case, you must configure ports for listening. Note However, you can choose only one of the protocols when you configure the GA instance. After you configure the GA instance, you can add a listener port for the other protocol on the GA instance details page.	TCP
Port	Enter a port number that ranges from `5912 to 5941`.	5912–5941
Configure an endpoint group step
Region	Select the region where cloud computers are deployed.	China (Guangzhou)
Backend Service Type	Select Custom Domain Name from the drop-down list.	Custom Domain Name
Backend Service	Specify the default gateway domain name for the region where cloud computers are deployed. China (Fuzhou - Local Region): gw-cn-fuzhou.wuying.aliyuncs.com China (Guangzhou): gw-cn-guangzhou.wuying.aliyuncs.com China (Hong Kong): gw-cn-hongkong.wuying.aliyuncs.com Philippines (Manila): gw-ap-southeast-6.wuying.aliyuncs.com Thailand (Bangkok): gw-ap-southeast-7.wuying.aliyuncs.com US (Silicon Valley): gw-us-west-1.wuying.aliyuncs.com German (Frankfurt): gw-eu-central-1.wuying.aliyuncs.com Note If the preceding regions cannot meet your business requirements, submit a ticket.	gw-cn-guangzhou.wuying.aliyuncs.com
Cross-border Acceleration Settings	Read Compliance Commitments Regarding Cross-border Data Transfers.	Select Agree to the Preceding Compliance Agreement.

In the Configuration Review step, check the configurations and click Submit.

Step 2: Add a listener port

After you create the GA instance, you must configure a listener port for the other protocol as described in Step 1.

Log on to the GA console.
In the left-side navigation pane, choose Standard Instance > Instances.
On the Instances page, find the GA instance and click the instance ID.
On the Listeners tab of the instance details page, click Add Listener.

On the Add Listener page, configure the parameters described in the following table and click Next to go to the subsequent steps. For parameters that are not listed in the table, use the default values.

Parameter	Description	Example
Configure Listener & Protocol step
Protocol	Select a protocol for the listener. Cloud computers use TCP and UDP. In this case, you must configure ports for listening. If you add a listener port for the TCP protocol in Step 1, you must add another listener port for the UDP protocol.	UDP
Port	Enter a port number that ranges from `5912 to 5941`.	5912–5941
Configure Endpoint Group step
Region	Select the region where cloud computers are deployed.	China (Guangzhou)
Backend Service Type	Select Custom Domain Name from the drop-down list. The value must be the same as you specified in Step 1.	Custom Domain Name
Backend Service	Specify the default gateway domain name for the region where cloud computers are deployed. The value must be the same as you specified in Step 1.	gw-cn-guangzhou.wuying.aliyuncs.com

In the Configuration Review step, check the configurations and click Submit.

Make sure that the listener ports for the TCP and UDP protocols are displayed on the Listeners tab.

Step 3: Obtain a domain name

After you configure the listener ports, you can obtain a custom domain name in the GA console. You can use the domain name to replace the default gateway domain name of the region where cloud computers are deployed.

Log on to the GA console.
In the left-side navigation pane, choose Standard Instance > Instances.
On the Instances page, find the instance that you created in Step 1 and click its ID.
On the instance details page, click the Instance Information tab and click Copy next to the value of the CNAME parameter. Then, the custom domain name is obtained.

Step 4: Configure the custom domain name for an office network

After you obtain the custom domain name, you can go to the EDS console to configure the domain name for the office network in which cloud computers reside.

Log on to the EDS Enterprise console.
In the left-side navigation pane, choose Networks & Storage > Office Networks.
In the upper-left corner of the top navigation bar, select a region.
On the Office Networks page, find the office network that you want to manage and click its ID.
In the Network Information section on the details page, click Configure next to Custom Domain.
In the Configure Custom Domain dialog box, enter your custom domain name and click OK.
