    Creating VPC for TencentDB for SQL Server

      Tencent Cloud provides Virtual Private Cloud (VPC), a platform for hosting TencentDB instances. You can launch Tencent Cloud resources in a VPC, such as TencentDB instances.
      A common scheme is to share data between a TencentDB instance and a web server running in the same VPC. This document uses this scheme to create a VPC and add a TencentDB instance to it. This document describes how to add CVM and TencentDB for SQL Server instances in the same VPC for interconnection between Tencent Cloud resources over the private network in the VPC.

      Step 1. Create a VPC

      A VPC has at least one subnet, and Tencent Cloud service resources can only be added in a subnet.
      1. Log in to the VPC Console.
      2. Select the region of the VPC at the top of the list and click +Create.
      3. Enter the VPC information and initial subnet information and click Create. The CIDRs of the VPC and subnet cannot be modified after creation.
      The VPC CIDR can be any of the following IP ranges. If you want two VPCs to communicate with each other over the private network, their CIDRs should not overlap:
      10.0.0.0 - 10.255.255.255 (mask range required to be between 16 and 28)
      172.16.0.0 - 172.31.255.255 (mask range required to be between 16 and 28)
      192.168.0.0 - 192.168.255.255 (mask range required to be between 16 and 28)
      The subnet CIDR must be within or the same as the VPC CIDR. For example, if the IP range of a VPC is 192.168.0.0/16, then the IP ranges of subnets in it can be 192.168.0.0/16 or 192.168.0.0/17 for example.

      Step 2. Create a subnet

      You can create one or more subnets at the same time.
      1. Log in to the VPC Console.
      2. Click Subnet on the left sidebar to enter the management page.
      3. Select the region and VPC of the subnet to be created and click +Create.
      4. Enter the subnet's name, CIDR, availability zone, and associated route table.
      5. (Optional) Click +New Line to create multiple subnets at a time.
      6. Click Create.

      Step 3. Create a route table and associate it with a subnet

      You can create a custom route table, edit its routing policy, and associate it with a specified subnet. The routing table associated with the subnet is used to specify outbound routes for the subnet.
      1. Log in to the VPC Console and select Route Tables on the left sidebar.
      2. Select the region and VPC at the top of the list and click +Create.
      3. In the dialog box that pops up, enter the name, network, and new routing policy and click Create. Return to the route table list and you can see the created routing table.
      4. Select Subnet on the left sidebar in the console, select the subnet to be associated with the routing table, and click Change Route Table in the Operation column to associate it.

      Step 4. Add a CVM instance

      1. Log in to the VPC Console.
      2. Click Subnet on the left sidebar to enter the management page.
      3. Click the "Add CVM" icon in the row of the subnet where the CVM is to be added.
      4. Complete the purchase of a CVM instance as prompted on the page. For more information, please see Purchase Methods in the CVM documentation.

      Step 5. Add a TencentDB instance

      1. Log in to the TencentDB for SQL Server Console and click Create Instance to enter the purchase page.
      2. In the Network Type section on the purchase page, select VPC, choose the previously created VPC and the corresponding subnet, and add the newly purchased TencentDB instance to the VPC.
