What is the best place to read/write/store a small amount of data online?

I want to be able to store, retrieve, and modify a small amount of textual data (< 2 mb) online. What service should I use to be able to do this programatically (in Java)?

From stackoverflow

• You can try Google's App Engine. http://code.google.com/appengine/docs/whatisgoogleappengine.html

  Also there is Amazon S3. http://aws.amazon.com/s3/

  I know a few Open Source people using these tools to store online persistent data to useful effect.

  Penchant : any free alternatives?

  Jotham : As far as I am aware the Datastore on App Engine has a free quota mode. http://code.google.com/appengine/docs/quotas.html

• OpenDHT sounds like it will do what you need it to.

• Try Google Spreadsheets (Java API Reference). You can upload a CSV which gets automatically converted to a spreadsheet, then you can query or edit it programmatically, or manipulate it online, then if you need to get it as CSV you can export it.
