Re: Amazon EBS
I don't think that Google is really "attacking" EBS as per the core of what EBS is. In fact, EBS (and EBS-like functionality) is really what enables IaaS for most applications, because it allows for the snapshot and restoring of large amounts of data quickly; without it, you can't run enterprise applications on a provider. And Google's version of EBS (persistant storage) was too feature-limited upon its beta launch to allow Google to go GA until they added significant features to persistent storage to make it close enough to EBS. (Specifically, you couldn't attach/detach from different instances, and the snapshot/restore functionality wasn't really there).
GCE is really providing an EBS-like experience that has some potential advantages over EBS, but everything GCE is saying that AWS doesn't provide properly with EBS can actually be implemented with EBS--just with some additional scaffolding. And while EBS has been the main cause of AWS issues over time, I would submit that that's just because of use. I would bet a significant sum of money that GCE will similarly see quite a few outages related to its persistent storage once (if) people really start using GCE.
