Preparing Resources
Introduction
This section describes how to buy, modify, and delete instances on the MAS console.
Preparing Required Resources
Prepare a Virtual Private Cloud (VPC), subnet, and security group before you start. Each MAS instance is deployed in a VPC and bound to a specific subnet and security group. In this way, MAS provides an isolated virtual network environment and security protection policies that can be easily configured and managed by users.
- For details about how to create a VPC and subnet, see Creating a VPC. To create and use a subnet in an existing VPC, see Creating a Subnet for the VPC.
- For details about how to create a security group, see Creating a Security Group. To add rules to a security group, see Adding a Security Group Rule.
