CreateVpc

Description

Creates a VPC with the specified CIDR block. The smallest VPC you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses). To help you decide how big to make your VPC, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide.

By default, each instance you launch in the VPC has the default DHCP options, which includes only a default DNS server that we provide (AmazonProvidedDNS). For more information about DHCP options, see Using DHCP Options with Your VPC in the Amazon Virtual Private Cloud User Guide.

Request Parameters

CidrBlock

The CIDR block you want the VPC to cover (for example, 10.0.0.0/16).

Type: String

Default: None

Required: Yes

instanceTenancy

The supported tenancy options for instances launched into the VPC. A value of default means that instances can be launched with any tenancy; a value of dedicated means all instances are launched as dedicated tenancy instances regardless of the tenancy assigned to the instance at launch. Setting the instance tenancy to dedicated runs your instance on single-tenant hardware.

Type: String

Default: default

Required: No
