Instance count: This is the setting for host scaling. For more information about features that require the Standard SKU, see Configuration settings - SKU. The Standard SKU lets you configure the instance count for host scaling and other features. Choose the region in which your virtual network resides. ![]() Region: The Azure public region in which the resource will be created. Name: Type the name that you want to use for your bastion resource. Project details are populated from your virtual network values. On the Create a Bastion page, configure the settings for your bastion host. This lets you configure specific additional settings when deploying Bastion to your VNet. On the Bastion page, select Configure manually. On the page for your virtual network, in the left pane, select Bastion to open the Bastion page. Once Bastion is deployed, you can connect securely to any VM in the VNet using its private IP address. This section helps you deploy Bastion to your VNet. All Azure Bastion resources deployed in subnets of size /27 prior to this date are unaffected by this change and will continue to work, but we highly recommend increasing the size of any existing AzureBastionSubnet to /26 in case you choose to take advantage of host scaling in the future. For more information about Azure Bastion, see What is Azure Bastion?įor Azure Bastion resources deployed on or after November 2, 2021, the minimum AzureBastionSubnet size is /26 or larger (/25, /24, etc.). If your VM has a public IP address that you don't need for anything else, you can remove it.Īzure Bastion is a PaaS service that's maintained for you, not a bastion host that you install on one of your VMs and maintain yourself. After the deployment is complete, you connect to your VM via private IP address. In this tutorial, you deploy Bastion using the Standard SKU tier and adjust host scaling (instance count). When you connect to a VM, it doesn't need a public IP address, client software, agent, or a special configuration. After Bastion is deployed, you can connect (SSH/RDP) to virtual machines in the virtual network via Bastion using the private IP address of the VM. When you use manual settings, you can specify configuration values such as instance counts and the SKU at the time of deployment. It provides near-like console access that does not require any public IP address or VPN gateway connectivity to the VMs it connects to.This tutorial helps you deploy Azure Bastion from the Azure portal using your own specified manual settings. It enables the use of the Azure Portal to perform the RDP and SSH connection to any virtual machine within the virtual network they are deployed in with a secure, cost effective solution. Even a jump box exposed to the public Internet has several security risks.Īzure Bastion is the Platform as a Service (PaaS) solution to a jump box in Azure. Microsoft Azure, being a cloud solution, understands that users cannot expose RDP and SSH to the public internet in most scenarios. It is explicitly used to provide a controlled means of access to manage other resources in the network. It is typically more locked down and hardened and only accessible from a trusted network. This server can be on your DMZ or internal network. In some scenarios that may be true depending on how the resource was deployed.Ī Jump box server, while very similar to a Bastion host, is slightly different. ![]() Some use Bastion and Jump box interchangeably. This host is typically placed in outside your network or security zone to protect against attacks and not expose your internal resources to the public Internet. In technology, a Bastion host is used to securely connect to resources on your network, typically for a single purpose.
