Infrastructure and Plan
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 an Azure Managed Kubernetes Service cluster that you use for container orchestration.
When creating an Infrastructure, you 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:
Select Administrator -> Infrastructure from the navigation menu.
Click Add.
Define the Infrastructure by completing the fields on the Add Infrastructure form.
Click Create. The Infrastructure is created and is listed on the Infrastructure page.
Enable Kubernetes for AKS
To enable an AKS cluster for Azure, follow these steps.
Up to one instance (0 or 1) of an AKS 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
Cloud providers limit the number of Infrastructures that can run in each region. If you have completed the steps to create an Infrastructure and it doesn't show a Status of Complete, try selecting a different region.
Enabling an encrypted Azure storage account
You can choose to encrypt your Azure storage account by configuring a Key/Value pair in the Infrastructure.
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.
