Server to host bam files

I am looking for a free (or relatively inexpensive) public server to host a few bam files that I would like to view in an online genome browser. I don't expect these bam files to be big so storage space is not much of a concern.

I have seen this note by the folks at UCSC Genome Browser. I could not get CyVerse working. FigShare is not really an option for me as I expect these files to change. Finally, GitHub was an option but I could not figure out how, for a bam file, the browser can find the path for the index.

Is there a public server that you use for something like this?
