When you access cloud computers provided by Elastic Desktop Service (EDS) across regions over the Internet, you may experience high latency and screen stuttering, which degrades the end-user experience. You can use Global Accelerator (GA) to route user traffic to the nearest Alibaba Cloud access point. The traffic is then forwarded to the cloud computers over Alibaba Cloud's accelerated global network. Because Elastic Desktop Service (EDS) Enterprise is integrated with GA, you can enable GA for an office network with a single click in the EDS Enterprise console.
Example scenario
An enterprise with headquarters in the Germany (Frankfurt) region uses Elastic Desktop Service (EDS) Enterprise to connect and centrally manage its branch offices across the globe. Due to a poor Internet connection, some end users experience high network latency, which affects their productivity.
To resolve this issue, the enterprise uses the GA integration feature in EDS. This routes user traffic to the nearest Alibaba Cloud access point for acceleration, significantly improving collaborative efficiency.
Limits
-
The one-click GA activation for office networks has the following limits:
-
Regions: This feature is available in China (Shenzhen), China (Heyuan), China (Guangzhou), China (Chengdu), China (Qingdao), China (Beijing), China (Shanghai), China (Hangzhou), China (Hong Kong), Singapore, Malaysia (Kuala Lumpur), Thailand (Bangkok), Indonesia (Jakarta), US (Silicon Valley), Germany (Frankfurt), UK (London), and Japan (Tokyo).
-
Note
Global Accelerator only supports Premium office networks. Basic office networks are not supported.
-
-
The Global Accelerator instance that Elastic Desktop Service (EDS) Enterprise creates for you can accelerate only cloud computer connections. You can view the configuration in the Global Accelerator console but cannot modify it.
Prerequisites
You have deployed the basic resources for Elastic Desktop Service, and end users can log on to Alibaba Cloud Workspace terminals to use cloud computers.
Procedure
Step 1: Enable GA for an office network
-
In the Elastic Desktop Service (EDS) Enterprise console, go to the page. In the top navigation bar, select the target region and then click the ID of the target office network.
-
On the office network details page, in the Network Information section, find Global Accelerator and click Activate Now.
-
On the GA Instance Configurations tab, configure the parameters and click Next.
By default, a standard pay-as-you-go GA instance is created. The fees include the GA instance fee, CU fee, and data transfer fee.
Configure the Global Accelerator instance name and select a resource group.
-
On the Configure User Acceleration Regions and Bandwidth Allocation tab, configure the acceleration regions, allocate bandwidth, and then click OK.
-
Acceleration Region: Click Add Region, select the regions that are closest to your end users, and then click Add to List.
-
Assign Bandwidth: To set different maximum bandwidth values for multiple regions, select Set Bandwidth by Region. To set the same maximum bandwidth for all regions, select Set Bandwidth for All.
ImportantIf the maximum bandwidth is set too low, traffic may be throttled or dropped. Plan the maximum bandwidth based on your business requirements.
-
Step 2: Verify the acceleration performance
This example uses an Alibaba Cloud Workspace terminal in the China (Hangzhou) region for testing. On the desktop, open the floating toolbar, click Status Monitor, and hover over the Latency metric to view the Client-to-Desktop Latency data.
-
Test the latency from the Alibaba Cloud Workspace terminal to the cloud computer before you enable GA.
In the status bar at the top of the Alibaba Cloud Workspace client, view the latency information, or click Status Monitor to open the monitoring panel. In this example, the local network latency is 250 ms, and the latency from the client to the cloud computer is 253 ms.
-
Test the latency from the Alibaba Cloud Workspace terminal to the cloud computer after enabling GA.
In the Alibaba Cloud Workspace client management panel, click Status Monitor to view the network latency. After GA is enabled, the local network latency is 5 ms, and the latency from the client to the cloud computer is 196 ms.
The results show that GA reduces the latency from the Alibaba Cloud Workspace terminal to the cloud computer.
The actual acceleration performance of GA may vary depending on your workloads.
More operations
On the details page of the office network, in the Network Information section, find Global Accelerator and click View Configuration. On the instance details page, you can perform the following operations:
-
View monitoring charts and access logs
At the top of the page, click Go now to view the information in the Global Accelerator console.
-
View billing information
On the Instance Information tab, click Bill Query in the Billing Information section.
-
Modify accelerated regions
On the Accelerated Region tab, click Add Region to Accelerate. In the panel, add or remove regions, and click OK.
-
Modify bandwidth
On the Accelerated Region tab, click Edit Bandwidth. In the panel, modify the bandwidth allocation settings, and click OK.
-
Stop global acceleration
In the upper-right corner of the page, click Stop Global Acceleration. In the confirmation dialog box, click OK.
WarningAfter you stop acceleration, all resources of the Global Accelerator instance, including the accelerated region IP addresses, are released. Traffic is immediately terminated, and this operation is irreversible.
