Azure Bastion is a platform-as-a-service (PaaS) offering that allows you to connect to your Azure VMs without exposing them to the public internet. It acts as a secure gateway, enabling you to access your VMs using RDP and SSH protocols directly from the Azure portal. It eliminates the need for public IP address on the VMs and reducing the attack surface and enhancing security.
