IMHO, the issues with the cloud are almost always at a layer above the infrastructure. --L Reddit has routinely had EBS volumes either outright fail (2 major outages in the last month/month and a half, both caused by several EBSs vanishing), or show some not insignificant degradation in performance, and it seems barely a month goes by when I don't hear someone on twitter talking about similar with their infrastructures. Most of the problems I've heard about do seem to revolve around EBS, however, rather than their other services. It may be just the nature of people to pick on and shout about the biggest targets, but I'm reasonably sure almost all the problems I hear about relating to cloud services revolve around Amazon and rarely their competitors. http://highscalability.com/blog/2010/12/20/netflix-use-less-chatty-protocols-in-the-cloud-plus-26-fixes.html When it comes to other layers in the infrastructure probably one of the most talked about problems is network latency between instances. Netflix had to specifically re-engineer their platform because of it (and other major users talk of similar changes). There is almost certainly an argument to be made that the outcome of the forced re-engineering is a good thing as it's generally boosting resilience, but that it's been forced on them in such a way surely should also be of some cause for concern also. Reddit seem to be working hard to make their platform as resilient as possible to their routine problems cause by the infrastructure. One of their outgoing dev's gave a pretty interesting read on the problems they'd experience with Amazon: http://www.reddit.com/r/blog/comments/g66f0/why_reddit_was_down_for_6_of_the_last_24_hours/c1l6ykx I absolutely do think cloud hosting / virtual servers have value and use and shouldn't be underestimated or written off as a fad, but I'm also not entirely convinced at the moment that Amazon is a vendor to particularly trust with such services, I'd probably also argue that anyone keeping their eggs in one basket and relying on a single vendor for such services is taking a significant risk. There are plenty of tools and libraries out there to help provide a standard API for rolling out servers on different platforms. It seems crazy not to take advantage of the flexibility the cloud offers to remove as many SPOFs as possible. Paul
OT: Question/Netflix issues?
Greetings, I know this is way off topic, but is anyone else getting calls/tickets about Netflix access problems? I tried (sucessfully) to duplicate the issues, seems like extremely slow responses from the servers I have tested, as well seems the web servers are also either overloaded or just dropping packets. Just wondering if anyone else is seeing the same. Kind Regards, -Joe Blanchard

Where do you pick up their feeds from ? A lot of their content seems to come from CDNs like Akamai in my neighbourhood (in this case, Torix).
