I'm pleased to announce the launch of Gluo: a handy wrapper for net/http applications that allows to deploy the exact same binary to AWS Lambda and (bare-metal/virtual) servers.
If you want to use your current net/http code with little modification, Gluo is your choice. It's a drop-in replacement: just call gluo.ListenAndServe instead of http.ListenAndServe.
PS: version 0.0.1 was released the same day as AWS announced their official support for Go in AWS Lambda, but I waited for a second release in order to improve code coverage.
