Creating a VPC

A VPC is logically isolated, configurable, and manageable virtual network for cloud servers, cloud containers, and cloud databases. It improves resource security and simplifies network deployment on the cloud. With a VPC, you can configure and manage the networks in the VPC, and make changes to these networks as needed, quickly and securely. For more information about VPC, see VPC Overview.

When creating a VPC, create the subnet 10.10.1.0, which is used as the server/client plane IP address and system replication/heartbeat plane IP address of SAP and DB2.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. In the navigation pane on the left, click and choose Network > Virtual Private Cloud.

  4. Click Create VPC on the right of the page.

  5. Configure required parameters as prompted based on Table 1.

    Item

    Parameter

    Description

    Basic information

    Region

    A region is a geographical area where you can run your VPC service. Each region comprises one or more availability zones (AZs) and is completely isolated from other regions. Only AZs in the same region can communicate with one another through an internal network. You can use the region selector on the upper left of the page to change the region.

    Name

    VPC name

    Network segment

    CIDR block of the VPC. The CIDR block of a subnet can be the same as the CIDR block for the VPC (for a single subnet in the VPC) or a subset of the CIDR block for the VPC (for multiple subnets in the VPC).

    The following CIDR blocks are supported:

    10.0.0.0/8~24

    172.16.0.0/12~24

    192.168.0.0/16~24

    Configure the CIDR block based on the subnet information provided in Network Planning.

    Enterprise project

    The enterprise project to which the VPC belongs.

    An enterprise project facilitates project-level management and grouping of cloud resources and users. The name of the default project is default.

    For details about creating and managing enterprise projects, see the Enterprise Management User Guide.

    Tag

    The VPC tag, which consists of a key and value pair. You can create 10 tags for a VPC. This parameter is optional. Click Advanced Settings to configure it.

    For details about the tag naming rules, see VPC Tag Naming Rules.

    Default subnet

    AZ

    An AZ is a geographic location with independent power supply and network facilities in a region. AZs are physically isolated, and AZs in the same VPC are interconnected through private networks.

    Name

    Subnet name

    CIDR Block (of the subnet)

    The CIDR block for the subnet. This value must be within the VPC CIDR block. Configure the subnet CIDR block based on the information provided in Network Planning.

    Advanced settings

    Click Advanced Settings to set parameters such as Gateway and DNS Server Address.

    Gateway

    Gateway address of the subnet

    DNS server address

    External DNS server addresses are used by default. If you need to change the DNS server address, ensure that the DNS server addresses you configured are available.

    DHCP lease time

    Period during which a client can use an IP address automatically assigned by the DHCP server. After the lease time expires, a new IP address will be assigned to the client. The unit is day.

    Tag

    Subnet tag, which consists of a key and value pair. You can add 10 tags for a subnet. This parameter is optional.

    For details about the tag naming rules, see VPC Tag Naming Rules.

    Add a subnet

    You can click Add Subnet to add a subnet.
