It's a shame that ISPs are routing spoofed udp packets, like in DRDOS attacks and are not made liable for this. When a fake UDP packet, spoofed with the source IP being replaced by yours, is sent to an amplifying system, like quake/cs/hl/codt server or a dns, then you get the answers... A lot. Why the hell those guys route trafic issued from an IP that is not in their range ? It's a line of config in routers. (Not exactly rocket science like a friend of mine says) Well simply because they make money out of upload trafic... Shame. Ok it would only solve the DDOS based on UDP spoofed packets, but it's not few. Btw I like the ideas expressed here lf a license to use a computer. Something giving the basics at least. I also like the idea of a reputation system (we have one in our high security cloud) to ban the IPs doing carp tepeatidly, by blackholing them, after a neutral group of netadmins decides it.

I'm running a French company which make dedicated hosting for Magento. Hell yes it need power and optimization but in the end, many customers says it's a budget assigment shift. Before, you had to pay for everything once you had a E-commerce site. Want to import a catalog ? pay. Want to manage a skin or make some dedicated shops ? pay. etc... The backoffice is very easy to use but very powerfull so seeing books around how to use it best is a good thing I think ! Now, you can handle it by yourself and this definitly lower you TCO. On the other hand, having a such flexible framework implied the use of a framework over Zend. all of this is Object, flexible etc but heavy to run. So you have to use 30% of what you previously gave to web agencies to your hosting company to make it run smoothly. In the end, a big server (optimized) can take up to 50 000 Uniq visitor a day, which is not a shame. (the site need to be decent of course). Most coders don't even know there's a cache mecanism and that he needs to be called explicitly, making the solution heavier. Usually (I alread host 150+ sites), count ~2% of the online revenue for hosting costs and -50% for the costs around maintainance, one in the other, middle and big E-commerce site are spending less money.
