    how to make external data available to a cluster

    tek no Novice

      I have an app running on a JBoss 4.02 cluster. A requirement of this app is that it must serve various files to clients. The files are mostly 60-80K, but there are a lot of them and they will be changed/added regularly. I have a number of possible solutions in mind but would like to hear what other people do in such situations.

      1. Have a server set up as a content repository, Place files on it and have the cluster query this machine, making local copies if necessary.

      PROS: Simple to set up and control
      CONS: introduces SPOF, could lead to a bottleneck

      2. Place files in JBoss farm directory and have JBoss far them out to other nodes. Use a background process ( maybe a custom deployer? ) to register chages and inform the app.

      PROS: uses current JBoss processes
      CONS: Leads to messy deploy directory ( maybe canbe cleaned up by making copies elsewhere?? ), ...

      3. Place files as BLOBs in a DB.

      PROS: simple, especially if using hibernate with JBossCache
      CONS: Potential performance issues, dealing with BLOBs issues, ... ?

      4. Let users upload files using a web interface. Store files in JBossCache and let it manage them.

      PROS: Gives users control of their files
      CONS: memory issues?, how do i organise these files, what if iwant query the number of files of a particular type in the system

      Does anyone have ideas what a good solution would be? Anyone have any comments to make about any of the above possible solutions?

      thanks
