Agreed, however the article is about adoption of cloud services. Hopping on temporarily for extra capacity doesn't seem like the kind of adoption they are trying to encourage. The other problem is that if you run a mix of in house and out of house services, the latency between the two sets of servers may be too high to be of much use. Say for example your DB server is on your network, and you need more capacity on your web servers. You could fire up a few extra EC2 instances and set up a VPN link from them to your DB server, but most likely the latencies are going to be too high to be useful. So cloud services aren't necessarily all that useful for temporary capacity either. To some extent it's all or nothing, at least for web services.
