Well, what we used to call distributed computing became Grid computing and now the buzzword is Cloud computing.
Along with the progress in marketing buzzwords there has also been great progress in capability with amazing new stuff being added all the time. For example Google is supporting Java Servlets running "in the cloud."
Personally I use the Amazon S3 storage system for many many megabytes of backup files.
My website contains links to some articles I have written on distributed -> Grid -> Cloud computing.
