After you deploy an application on Serverless App Engine (SAE), you may need to modify network access control or adjust connectivity between resources. You can change the security group to control inbound and outbound traffic, or change the vSwitch to connect the application to a different subnet within the same virtual private cloud (VPC).
Prerequisites
Before you begin, make sure that you have:
An application deployed on SAE
A security group or vSwitch available in the same VPC as the application
Change the security group
Log on to the SAE console.
In the left-side navigation pane, click Applications. In the top navigation bar, select a region. Then, click the name of the application.
On the Basic Information tab, find the Application Information section and click Change Security Group in the Security Group field.
In the Change Security Group dialog box, select the security group and click OK.
In the confirmation dialog box, click Restart application to apply the change, or click Cancel to apply the change during the next deployment.
After you change the security group, you must restart or redeploy the application for the change to take effect. Make sure that the required ports are enabled in the new security group.
Verify the result
On the Basic Information tab, check the Security Group field. If the value shows the new security group, the change is successful.
Change the vSwitch
Log on to the SAE console.
In the left-side navigation pane, click Applications. In the top navigation bar, select a region. Then, click the name of the application.
On the Basic Information tab, find the Application Information section and click the deployment recommendation link in the vSwitch field. The Multi-vSwitch Deployment dialog box appears.
In the Multi-vSwitch Deployment dialog box, select the vSwitch that you want to use. In the Effective policy section, select when the change takes effect:
The next deployment takes effect.: The vSwitch change takes effect during the next deployment.
Effective Immediately: The vSwitch change takes effect immediately.
Click OK.
You can select a maximum of three vSwitches at a time.
Verify the result
On the Basic Information tab, check the vSwitch field. If the value shows the new vSwitch, the change is successful.
