![]() ![]() Azure Bastion is now generally available in six Azure regions - West U.S., East U.S., West Europe, South Central U.S., Australia East, and Japan East. One good approach to overcome the above challenges is to allow remote access to a fixed cloud endpoint, which has sole access to the AKS Cluster. For Azure bastion, no public IP address is required on Azure Virtual Machines. Using a bastion host can help limit threats such as port scanning and other types of malware targeting your VMs. While some users get access to a jump box or an Azure Bastion host, it lacks many notable features like AD authentication or a true desktop experience. Azure Bastion is a more secure way for RDP/SSH session to the target virtual machines in the virtual network. It is easy to initiate a remote Azure Bastion session directly from the Azure portal. Azure bastion can be configured so fast with few clicks only instead of managing the whole network configurations. Azure bastion has the capability to take Remote Desktop Protocol (RDP) and Secure Shell (SSH) inside a web browser itself. By using Azure Bastion, organizations do not require to expose virtual machines using public IP Addresses. The number of connections per instances depends on what actions you are taking when connected to the client VM. Each instance can support 10-12 concurrent RDP/SSH connections. If you use the Standard SKU, you can specify the number of instances. It is a platform-managed PaaS service provided in the Azure. When you configure Azure Bastion using the Basic SKU, two instances are created. On the other side, with a recent announcement by Microsoft, it announced one more service like Jumpbox with additional capabilities named Azure Bastion. ![]() Then, by using this VM, we can connect to the other Azure VM’s using dynamic IP. This VM is called Jumpbox also named as Jump server. By this approach, we will enable only one VM in Azure to enable connectivity over the internet. In this situation, the Azure Jumpbox helps us. However, this will expose a lot of VM’s directly to the VM. If we do not have connectivity to the virtual network from the on-premise network, then we need to create endpoints/NAT rules to VM to get connectivity from the internet. We connect to the dynamic IP address of the Azure virtual machine. The jump box is given a public IP address allowing it to be accessed from the internet. When we connect to the Azure virtual machine then it connects your on-premise network to Azure virtual network using site-to-site virtual network or express route. We can connect to this virtual machine using PowerShell or remote desktop connection (RDP). This virtual machine is on the virtual network on the Azure cloud. When we create a virtual machine in the Azure cloud.
