How cool would it be to be able to access the services, hosted on your development environment running the code, from anywhere in a secure and controlled way? Even if you are behind firewalls and gateways, as long as you have internet connectivity your development machine can be reached from the internet with the help of Microsoft Dev Tunnels. In this session we will discover the scenarios enabled by Dev Tunnels, such as debugging and testing your APIs locally when called from a remote environment running in the cloud. To have webhooks from pipelines call into your machine, or receive production events and run the handlers on your laptop, and much more. We will look at the architecture and inner workings of Dev Tunnels and how to securely setup tunnels and connections. You are going to learn to use the CLI and even programmatically add Dev Tunnel capabilities to your code and tools. Collaborating across developer machines, run production demos partially from your laptop, and have a fast development workflow for testing and debugging cloud applications has never been easier. It runs on your machine. Dev Tunnels will let you call it from anywhere.
