Google Storage : What it really is…

Yesterday Google formally announced Google Storage to a few (5000?) of us at Google I/O. Here is the gist of this as I see it from the various discussions/talks I attended. To begin with, I have to point out that there is almost nothing new in what Google has proposed to provide. Amazon has been doing this for years with its S3.  The key difference is that if you are a google customer you won’t have to look elsewhere for storage services like this one. Lets get the technical details out Its tries to implement a Strong consistency model (CA of the CAP: Consistent and Available). Which means data you store is automatically replicated in a consistent way across multiple datacenter Currently it replicates to multiple locations within US. In future it does plan to replicate across continents. Currently there are no controls to control how replication happens or to where. They plan to learn from usage in beta period and develop controls over time.
