Stop the hype”

I doubt it is either quick or easy if they have a reasonable amount of data. It is even harder when they use local attached storage rather than EBS and I am skeptical about using EBS for either HBase or Cassandra. When local storage is used it can take some time to transfer data to new servers.

Anyway:

The quick scaling is definitely something that the cloud delivers.

IMHO what “everyone is wrong about”(TM) is that cloud doesn’t have to be EC2 like (virtualized).

I don’t see a reason that (given the budget is available) I couldn’t have a pool of hardware servers that will be dynamically reassigned to certain application depending on current needs. And that is where you’ll win.

If you have 100 machines that always have a certain load level and 20 machines in the pool (yes I’m keeping the numbers on the lower level) then there’s nothing to keep you from assigning the pool machines to either frontend servers or “magically” fire up database instances that will replace currently broken parts of a cluster or some other usage that is need “right now”.

That won’t quite apply to the classic RDBMS model. This is where just a few well sized machines are perfect. But the “kool new aid” (a.k.a. NoSQL – there I said it!) like Cassandra, scalaris and such will definitely benefit from this model.

Now multiply those numbers by 100 and find:

* time of usage spike (per application)
* level of max usage that is acceptable to you

That is the win of the what is marketed of the cloud. Of course one could also just say: “Yes we can (re-)deploy our server really fast and we have lots of spare hardware that fits our environment” instead of “cloud”

.oO(But yes I agree cloud providers want you to use a lot of numbers of small instances and that isn’t always what’s needed)
