Setting Up Environments
=======================

To access DCS instances through a VPC, create a VPC and configure security groups and subnets for it before using DCS.

A VPC provides an isolated, user-configurable, and user-manageable virtual network environment for DCS. Using VPCs enhances resource security and simplifies network deployment.

Once you have created a VPC, you can use it for all DCS instances you subsequently create.

Procedure
---------

#. Log in to the management console.

#. Click |image1| in the upper left corner of the management console and select a region and a project.

#. Click **Service List**, and choose **Network** > **Virtual Private Cloud** to launch the VPC console.

#. On the **Dashboard** page, click **Create VPC**.

#. Create a VPC as prompted, retaining the default values unless otherwise required. For more information on how to create a VPC, see the *Virtual Private Cloud User Guide*.

   After a VPC is created, a subnet is also created in the subnet. If the VPC needs more subnets, go to :ref:`6 <en-us_topic_0077665192__li10954228154518>`. Otherwise, go to :ref:`7 <en-us_topic_0077665192__li1940024225812>`.

   In the navigation pane, choose **Virtual Private Cloud**. On the **Virtual Private Cloud** page, click the name of the VPC in which you intend to create a subnet. On the **Subnets** tab page, click **Create Subnet**.

   Create a subnet as guided by the VPC console, retaining the default values of the subnet parameters unless otherwise required.

   For more information on how to create a subnet, see the *Virtual Private Cloud User Guide*.
