Hi If your use case is like just store some files particularly if you need only a big storage medium then S3 should be fine.
HBase is a database where you want your data to be added from some specific source like a social site and you want to do some analysis.

I am looking for a use case: where in I want to store 10000 files and they will be accessed and modified and kept back in the S3. so there will be modifications of Files on S3 and trying to access them. For a use case like this do I need Hbase on S3? (or) if I just use S3, create bucket and keep on adding files and modify them on the need bases ________________________________ From: Sonal Goyal <sonalgoy...@gmail.com> To: dev@hbase.apache.org; Aditya Kumar <adityakumar...@yahoo.com> Sent: Thursday, November 24, 2011 7:11 PM Subject: Re: Amazon s3 and Hadoop/Hbase Aditya, S3 is a file storage service. It does provide versioning and key based file access, but it does not provide any processing paradigm, like Map Reduce for Hadoop. HBase provides random access to data - its more like a database in that you can have a key based access for records, and it is a columnar store. S3 can be compared with HDFS, the hadoop distributed file system, and in fact one can spin Hadoop clusters off S3 file system. Maybe if you explain your problem in detail, we can help you further on the mailing list. You can also read up the fundamentals on the Hadoop and HBase wiki, there is a high level introduction which can clear the basic doubts. Hope that helps.
