SSH is yet another example of an ancient technology that is still in wide use today. It may very well be that learning a couple of SSH tricks is more profitable in the long run than mastering a dozen Cloud Native tools destined to become deprecated next quarter.

One of my favorite parts of this technology is SSH Tunnels. With nothing but standard tools and often using just a single command, you can achieve the following:

• Access internal VPC endpoints through a public-facing EC2 instance.
• Open a port from the localhost of a development VM in the host’s browser.
• Expose any local server from a home/private network to the outside world.
