You should definetly read something about Hadoop: http://hadoop.apache.org/
Recomended book: http://www.amazon.com/Hadoop-Definitive-Guide-Tom-White/dp/0596521979
Commercial version: http://www.cloudera.com/

It provides framework for processing large amounts of unstructured data (MapReduce) (for example logs), and this is very mature solution used by Yahoo, Facebook and many more: http://wiki.apache.org/hadoop/PoweredBy
Pure SQL is avaiable with Hive,
Jobs can be written in C# using streaming mode, Hadoop has native Java API.

Amazon provides Hadoop hosting on cloud with Amazon Elastic MapReduce (EMR): http://aws.amazon.com/elasticmapreduce/
