Summary
Azure Bastion functions identically with traditional jump hosts in that it facilitates secure remote access to resources. On the contrary, Azure Bastion optimizes the workflow, strengthens security measures, and facilitates administration. It is an especially effective solution when working with Azure VMs. Conversely, traditional jump hosts provide enhanced flexibility at the expense of greater configuration and maintenance effort. Whether you choose Azure Bastion or not is based on your particular infrastructure and requirements, but for many organizations, it is a more secure and efficient method of enabling remote access to resources.

Azure Bastion
Azure Bastion is a Platform as a Service (PaaS) offering from Microsoft Azure that simplifies and enhances the security of remote access to Azure VMs. It provides a secure and seamless Remote Desktop Protocol (RDP) and Secure Shell (SSH) experience directly from the Azure portal, eliminating the need for public IP addresses, Network Security Groups (NSGs), or VPN connections. Here are some key advantages of Azure Bastion:
- Simplified Setup: Azure Bastion streamlines the setup process for remote access. You don’t need to configure complex networking components or manage public IP addresses.
- Enhanced Security: By eliminating the exposure of VMs to the public internet, Azure Bastion reduces the attack surface and enhances security. It uses TLS encryption to secure connections.
- Unified Access: Azure Bastion provides a unified and consistent way to access Azure VMs, regardless of their location or configuration.
- Multi-Factor Authentication (MFA): It integrates seamlessly with Azure Multi-Factor Authentication (MFA) for an additional layer of security.
- Auditing and Logging: All Bastion connections are logged and audited, helping you maintain compliance and track access.
Traditional Jump Hosts
A traditional jump host, or jump box, is a server positioned within a network to act as an intermediary between users and target servers. Users connect to the jump host, and from there, they can connect to other servers within the network. Here are some characteristics of traditional jump hosts:
- Complex Configuration: Setting up a jump host involves configuring networking, firewall rules, and user access. It can be complex and error-prone.
- Public IP Addresses: Jump hosts typically have public IP addresses, which expose them to the internet. This requires additional security measures, such as NSGs or firewalls, to restrict access.
- Varied Access Methods: Traditional jump hosts support various remote access methods, including RDP, SSH, and VPNs, depending on configuration.
- Manual Maintenance: Managing and maintaining jump hosts can be a manual and time-consuming process. It often requires updates and patches to ensure security.
