1. Secure Connectivity: Azure Bastion employs Remote Desktop Protocol (RDP) and Secure Shell (SSH) over Transport Layer Security (TLS) to ensure encrypted communication, safeguarding your data during transmission.

2. Zero Public IP: With Azure Bastion, you no longer need to assign a public IP address to your VMs. This not only enhances security but also streamlines the management of your VMs.

3. Multi-Factor Authentication (MFA): The service supports Azure Active Directory-based Multi-Factor Authentication, adding an extra layer of security to your remote connections.

4. Simple and Intuitive: Connecting to your VMs is as simple as clicking on them in the Azure Portal. No need for complex networking configurations or VPN setups.

5. Audit and Logging: Azure Bastion logs all remote connection activities, providing an audit trail for compliance and security monitoring.

Benefits of Azure Bastion:

1. Enhanced Security: By eliminating the need for public IPs on your VMs and ensuring encrypted communication, Azure Bastion significantly reduces the attack surface, enhancing the overall security posture of your infrastructure.

2. Simplified Management: The intuitive interface of Azure Bastion simplifies the process of connecting to your VMs. Forget about managing network security groups and dealing with complex VPN configurations.

3. Cost-Efficient: With Azure Bastion, you can save on costs associated with public IP addresses and VPN gateways. The pay-as-you-go model ensures you only pay for what you use.

4. Compliance Ready: The detailed logging and audit features of Azure Bastion make it a suitable choice for organizations with stringent compliance requirements.

Hands-On Example:

Let's walk through a simple example to demonstrate the power and simplicity of Azure Bastion.
