Have you used your AWS free tier up yet? If not, you should consider jumping on it. Free 24/7 micro server for a year - and you host the webserver, so you can install Apache, Nginx, whatever you want. I used it for a while, and the most I got charged was a couple quarters for going over on disk usage (DB was doing unnecessary reads / writes).
Also - this is a cool idea. As I've grown up in the same area, it seems like fewer and fewer people go all out for decorations around Halloween and Christmas, it who does with minimal effort. I can't find any examples (none in my area), but does it support pictures of the decorations?
I'm going to try to, video too; right now I ask for a link, but since I missed out on this big weekend I have time til Christmas to work on it. Obviously I can't add every house myself, but I've made it really easy to add a house and remove a house, all with a buffer to avoid spammers.
I have not touch AWS before, so I'll look into it. I went GAE because I'd used Udacity's Web Development course and in it they talk about how Udacity actually runs off GAE, so I thought if they did it, its do-able.
