There are a few differences:<p>* CGI is the closest UNIX thing you can find, fork a process, write on STDIN, read from STDOUT. Lambda actually is a framework for running javascript&#x2F;java&#x2F;python code, <i>from which you can call actual binaries</i>.<p>* Lambda&#x27;s attractive point is that containers are reused, which means that instead of paying the full price of a new process your context is already &quot;hot&quot;, even for the actual binary you run. That means less latency and less CPU usage, allowing you to scale far more easily<p>I&#x27;m no Lambda user so I&#x27;m possibly wrong, but the idea and execution behind sure looks nice.
