The exceptions are Bastion deployments in Korea Central and Southeast Asia, which do support zone redundancies. Previously deployed bastions may or may not be zone-redundant. Bastion servers also provide RDP and SSH connectivity to the workloads sitting behind the bastion, as well as further inside the network.Ĭurrently, by default, new Bastion deployments don't support zone redundancies.
Bastion host servers are designed and configured to withstand attacks. To contain this threat surface, you can deploy bastion hosts (also known as jump-servers) at the public side of your perimeter network. This is often due to protocol vulnerabilities. Exposing RDP/SSH ports over the Internet isn't desired and is seen as a significant threat surface. RDP and SSH are some of the fundamental means through which you can connect to your workloads running in Azure. Specifically, Azure Bastion manages RDP/SSH connectivity to VMs created in the local or peered virtual networks. FeatureĬonnect to target VMs in peered virtual networksĪccess Linux VM Private Keys in Azure Key Vault (AKV)Īzure Bastion is deployed to a virtual network and supports virtual network peering. The following table shows features and corresponding SKUs.

For more information, including how to upgrade a SKU, see the Configuration settings article. The Azure platform protects against zero-day exploits by keeping the Azure Bastion hardened and always up to date for you.Īzure Bastion has two available SKUs, Basic and Standard. Your VMs are protected against port scanning by rogue and malicious users because you don't need to expose the VMs to the internet.Īzure Bastion sits at the perimeter of your virtual network, so you don’t need to worry about hardening each of the VMs in your virtual network. No need to manage a separate bastion host on a VMĪzure Bastion is a fully managed platform PaaS service from Azure that is hardened internally to provide you secure RDP/SSH connectivity. For more information about NSGs, see Network Security Groups. This removes the hassle of managing NSGs each time you need to securely connect to your virtual machines.
Because Azure Bastion connects to your virtual machines over private IP, you can configure your NSGs to allow RDP/SSH from Azure Bastion only.
You don't need to apply any NSGs to the Azure Bastion subnet. No hassle of managing Network Security Groups (NSGs) You don't need a public IP address on your virtual machine. No Public IP address required on the Azure VMĪzure Bastion opens the RDP/SSH connection to your Azure VM by using the private IP address on your VM. This enables the traffic to traverse firewalls more securely. Your RDP/SSH session is over TLS on port 443. Remote Session over TLS and firewall traversal for RDP/SSHĪzure Bastion uses an HTML5 based web client that is automatically streamed to your local device. You can get to the RDP and SSH session directly in the Azure portal using a single-click seamless experience. Using Azure Bastion protects your virtual machines from exposing RDP/SSH ports to the outside world, while still providing secure access using RDP/SSH. When you connect via Azure Bastion, your virtual machines don't need a public IP address, agent, or special client software.īastion provides secure RDP and SSH connectivity to all of the VMs in the virtual network in which it is provisioned. It provides secure and seamless RDP/SSH connectivity to your virtual machines directly over TLS from the Azure portal or via native client. The Azure Bastion service is a fully platform-managed PaaS service that you provision inside your virtual network. Azure Bastion is a service you deploy that lets you connect to a virtual machine using your browser and the Azure portal, or via the native SSH or RDP client already installed on your local computer.
