Chapter 9.8 - 3 Ways To Connect

SSH, RDP, and Bastions

There are 3 ways to connect to your Virtual Machines.

• Secure Shell (SSH) is a protocol to establish a secure connection between a client and a server
  • This is how you can remotely connect to your Azure VM via terminal
  • SSH happens on Port 22 via TCP
  • RSA Key Pairs are commonly used to authorize access
• Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft which provides a user with a graphical interface to connect to another computer over a network connection
  • This is how you can remotely connect to Windows Server via Visual Desktop
  • RDP happens on Port 3389 via TCP and UDP
• Bastion: Azure Bastion is a service you deploy that lets you connect to a virtual machine using your browser and the Azure Portal. It provides secure and seamless RDP/SSH connectivity to your virtual machines directly from the Azure Portal over TLS. A bastion is a hardened instance that is monitored. Users connect to this VM which then establishes a connection to the target instance. Sometimes known as jump box since you have one extra security step.
