I think biggest news here is the possibility to share a server with someone else, with amazon acting as a broker of CPU time.<p>With virtual machines, we started to share physical resources which were otherwise wasted in dormancy. But even virtual machines were a waste of resources, as you need someone to set them up, keep them online and working. What if you could share the money you spent with those people and their knowledge?<p>Amazon just did that to you.<p>All some people want is to run code somewhere on the internet.<p>Amazon gather them together to share a server and an admin team.<p>In my point of view, Amazon Lambda is a huge improvement in efficiency for people around the world, as I (or someone else) can pay for a very tiny part of the work of a very specialized sysadmin and focus on my code.
