eBay's Scaling Odyssey & All I Need is Scale!

Those two slides presents eBay's principles & practices on distributed computing and cloud computing.

Principles described there are classical, but it is important to put them together and keep it in mind whenever we design systems to be scale out, like eBay. This slides are valuable as those are from the actual experience! However, it were more interesting if it included more detailed description how they did various trade-off, as that is easy to say but hard to generalize, and everything is case by case.

To them, it should be natural to see opportunity in cloud computing, for economic and operational reason. As their architecture is already ready-to-scale, it should be relatively easy to adopt cloud computing. To do so, they would like to figure out the difference between internal DC / internal cloud / 3rd party clouds, but it is not clear yet what the dominant 3rd party clouds will look like.
