Microsoft Azure Bastion - Secure access to Azure VMs

Microsoft Azure Bastion - Secure access to Azure VMs

Microsoft recently announced Azure Bastion as a new managed PaaS service that provides seamless RDP and SSH connectivity to your virtual machines over the Secure Sockets Layer (SSL). Azure Bastion is provisioned directly in your Virtual Network (VNet) and supports all VMs in your Virtual Network (VNet) using SSL without any exposure through public IP addresses. With this PaaS service announcement, Microsoft eliminated the need of Jumpbox Virtual Machine that was used to connect to the VMs without exposing them publicly.

Azure Bastion service is in Preview right now and is expected to be made generally available soon once it gets stabilized and matured as a product. Microsoft plans to bring in Azure Active Directory integration, adding seamless single-sign-on capabilities using Azure Active Directory identities and Azure Multi-Factor Authentication, and effectively extending two-factor authentication to your RDP/SSH connections. There are also plans to enhance the auditing experience for RDP sessions with full session video recording.

Sounds good? Then give it a try and explore the whole new possibilities with Azure Bastion service.

How will it work?
