Infrastructure (VPC) and Plan (configuration)

How Infrastructures and Plans work together to create a VPC

Infrastructures are abstractions that allow you to create a Virtual Private Cloud (VPC) instance in the DuploCloud Portal. When you create an Infrastructure, a Plan is automatically generated to supply the network configuration necessary for your Infrastructure to run. 
DuploCloud creates a VNET with a default subnet and a default Network Security Group (NSG). The creation of an Infrastructure takes about ten (10) minutes. 
Creating an Infrastructure
When you create a DuploCloud Infrastructure, you create an isolated environment that maps to a Kubernetes cluster. 
In DuploCloud, an Infrastructure maps one-to-one to a VPC in a specified region. It also maps to a Google Kubernetes Engine (GKE) cluster you use for container orchestration. 
When creating an Infrastructure, specify the number of availability zones, the region, VPC Classless Inter-Domain Routing (CIDR), and a subnet mask. DuploCloud creates two subnets in each availability zone, one private and one public, and sets up routes and a NAT gateway. 
Create a DuploCloud Infrastructure in the DuploCloud Portal:
1.Select Administrator -> Infrastructure from the navigation menu. 
2.Click Add.
3.Define the Infrastructure by completing the fields on the Add Infrastructure form. 
4.Select Enable GKE to enable GKE for the Infrastructure.
5.Optionally, select Advanced Options to specify additional configurations (public and private subnets, for example).
6.Click Create. The Infrastructure is created and is listed on the Infrastructure page.
GCP Add Infrastructure page
Up to one instance (0 or 1) of a GKS, EKS/Native, or ECS is supported for each DuploCloud Infrastructure.
When you create the Infrastructure, DuploCloud creates the following components:
VPC with 2 subnets (private, public) in each availability zone
Required security groups
NAT Gateway
Internet Gateway
Route tables
​VPC peering with the master VPC, which is initially configured in DuploCloud
About Plans and Infrastructures
Once the Infrastructure is created, a Plan (with the same Infrastructure name) is automatically created and populated with the Infrastructure configuration. The Plan is used to create Tenants.
