So it sounds like this index is static, produced somewhere else and only consulted read-only by 1..N instances of your webapp. Could you not just plop one uncompressed copy of the index into an EBS snapshot in an S3 bucket, and map the snapshot to each EB instance? Then just provide environmental information to the webapp as to where it should find the index. Your huge index doesn't have to live in the WAR then. I have *very* little experience with AWS, so it's quite possible I'm missing something. -- Mark H. Wood, Lead System Programmer mw...@iupui.edu Machines should not be friendly.
