After you deploy an application on Serverless App Engine (SAE), you can change the vSwitch and security group to which the application belongs based on your business requirements. This topic describes how to change the security group and vSwitch of an application in the SAE console.
Background information
A security group acts as a virtual firewall that controls access to or from one or more application instances. Each instance must belong to at least one security group. You can modify network access control to or from applications by changing the security group of the applications. For more information, see Overview.
A vSwitch is a basic network component that connects different cloud resources in a virtual private cloud (VPC). After you create a vSwitch, you can create resources in the vSwitch and associate the vSwitch with a route table or a network access control list (ACL). For more information, see Create and manage a vSwitch.
