Creating an Azure Bastion instance

Azure Bastion allows us to connect securely to our Azure resources without additional infrastructure. All we need is a browser. It is essentially a PaaS service provisioned in our virtual network that provides a secure RDP/SSH connection to Azure Virtual Machines. The connection is made directly from the Azure portal over Transport Layer Security (TLS).

Getting ready

Before we can create an Azure Bastion instance, we must prepare the subnet.

In order to create a new subnet for Azure Bastion, we must do the following:

  1. Locate the virtual network that will be associated with our Azure Bastion instance.
  2. Select the Subnets option under Settings and select the option to add a new subnet, as shown in Figure 9.1:
