Precisely. This is also what I'm seeing on my end. RAC makes it much easier to start with just enough resources and then expand as needed and as the needs evolve.

I've lost count of the number of times in the past where this situation has occurred: sites buy huge hardware upfront which then sits idle doing development for years, and then is undersized when production finally hits.

If anything has the potential to make RAC take off, it's this. The cost spread is so much better it's not even comparable.

Ah yes. But they've been doing that for a long time. The only difference with RAC is they're actually doing the right thing. For once... Received on Wed Feb 02 2005 - 15:04:04 CST
