Hi!WO runs perfectly on any UNIX OS (and Windows too, but that I never tried) with a JVM. So you should not have problems there.
Check <http://wiki.objectstyle.org/confluence/display/WO/Programming__WebObjects-Web+Applications-Deployment-Linux > and <http://wiki.objectstyle.org/confluence/display/WO/WebObjects+5.3.3+Deployment+on+FreeBSD+6.x >. The Linux page is very outdated, but grabbing a bit of info from the FreeBSD page and filling in any gaps, you should easily make it work. Use Java 5, not 4 or 6.
In an environment like Amazon's, I would avoid multicast on the adaptor/wotaskd configuration. Consider using a fixed list of IPs.
About Amazon itself, I would think twice before going forward with it. Many "web 2.0" companies that installed their apps on Amazon (mostly because of the hype, not because any real technical reasons) went back to "traditional" hosting because they had huge problems with speed, specially on the data storage. Which is expected, considering that they have no real storage at all. I consider S3 as a backup storage, but there's no real storage, as in, hard drives. You see people setting up PostgreSQL databases on monster machines, like 8- core machines with 16 GB of RAM and two fast RAIDs, one for base storage, and the other for WALs... then you look to what you can do in amazon, and it's a bad joke. And there's the obvious problem that is caused by having no real storage: if the instance goes down (power failure, hardware failure, it happens) surprise... you have no data! It's not that your hard drive died... it's like you don't have a hard drive! Only the backups. Being paranoid as I am, I really can't accept working in an environment where backups are not the last resource for recovering from a system downtime, but the first (and only) one.
Whatever you choose to do, good luck! Yours Miguel Arroz On 2008/04/17, at 15:20, Simon Liu wrote:
Hi, I am evaluating WO vs RoR for a project which will make use of Amazon Web Services. Can WebObjects be deployed on Linux with the exact same functionality as when deployed on OS X Server? From documentation, this should be possible, however in practice are there any issues or caveats? I would like to have my WO app on an Amazon EC2 instance (for low latency transfer to S3), and scale the number of running EC2 instances as required. Has anybody tried deploying WO in such an environment? Would JavaMonitor still be useable to manage the WO app instances and marshall notifictions between them, when they are running on a (dynamic) number of EC2s?
