Preparing Required Resources

Overview

Before creating a DCS instance, prepare the required resources, including a VPC and a subnet. Each DCS instance is deployed in a VPC and bound to a specific subnet and security group, which provide an isolated virtual network environment and security protection policies which you can easily configure and manage.

If you already have a VPC, subnet, and security group, you can use them for all DCS instances you subsequently create.

Required Resources

The following table lists the resources required by a DCS instance.

VPC and subnet

Different DCS instances can use the same or different VPCs and subnets based on site requirements. Note the following when creating a VPC and subnet:

  • The VPC and the DCS instance must be in the same region.
  • Retain the default settings unless otherwise specified.

For details on how to create a VPC and subnet, see Creating a VPC. If you need to create and use a new subnet in an existing VPC, see Creating a Subnet for the VPC.
