Launch Instances into the VPC

Now you can launch instances in the VPC for the required servers.

Background information

When launching an instance, you need to complete the required settings listed below:
  • Set up storage volumes for system data and independent PBX recording files.
  • Create a security group to control both inbound and outbound traffic for associated instances.
