AWS flicks switch for cloud storage replication

Amazon Web Services (AWS) has done something rather useful to its simple storage service (S3), namely making it possible to replicate data across regions. For the uninitiated, S3 is a cloud storage service that allows users to stuff stuff into the cloud, and even pick a “region” where it will land. AWS operates nine S3 regions* …

Reader suggestion: Using HDFS as generic iSCSI storage

Comment El Reg reader Greg Koss reckons the Hadoop filesystem can be used to build an iSCSI SAN. Er, say what? Here's his thinking: we could use Hadoop to provide generic storage to commodity systems for general purpose computing. Why would this be a good idea? Greg notes these points: Commodity storage pricing is roughly $60/TB in …

Replication for the rest of us

White paper There's a lot of information you'd want to replicate that wouldn't have been mission critical even two years ago. But you can't, because you have three incompatible storage systems, no budget for an extra data centre and no staff to run it if you did. Many more organisations need replication today than have it: losing even an …
