Whenever Amazon reduces the price of S3 (as they did last week)- I’m reminded of how important it is to be on the right “cost curve” for storage. There is still a bias in large enterprises toward on-premise storage that is provided by the likes of Dell/EMC. This bias is beginning to change – but there are still people who believe that the exorbitant cost of on-premise storage systems such as Isilon is justified relative to the cost of services such as S3. Now to be clear – there are times when specialized systems/storage are required (respect to my friends/colleagues in HPC) – however – for MOST large enterprise applications/systems – storage services such as S3 will do just fine.
In short – storage as a service is the right path – both in terms of tech AND in terms of cost. Companies such as ClearSky Data are making it easy to get on the right curve. (I have no vested interest in Clear-Sky – just a fan of their product/approach)
My favorite guideline for this is very simple : “when was the last time that EMC cut their prices by 30%?”
