(From my Zope 2 experience, though it should be relevant here). Building an HA architecture for Zope is pretty much like anything else ... There's very little that's Zope specific.
Minimum: - 8 boxes: 2 web, 2 app, 2 storage, 2 load balancers - On the web boxes run Apache with mod_rewrite to get you to the Zope instance(s) running on the app layer machines - Use ZEO w/ ZRS on the storage side. There are ways without ZRS probably, look at the Disk Replication Block Device (DRBD) project. I still bother to try and get single CPU machines, because of the whole Python GIL vs. Thread issue, though newer linuxes have CPU affinity. How you setup the load-blanacing will depend on a whole lot of factors, notably what software we use, and is beyond this list (Besides I don't do that bit, our "infrastructure" guys do that for me). We've head great success with that setup (3 app servers however) ... Vastly improved perfromance and availability.

I'm at the very beginning of what will hopefully be a successful deployment of some Zope3 apps. The big question I'm getting now from the infrastructure-minded people is what sort of hardware requirements I'll need (?) Given that I'm a bit of an Ubuntu nut, I wanted to look into a Sun server. I know that I won't need much in the way of storage, the minimum CPU and memory will do... after that I get a little lost :) If our final setup (a couple years down the line) will have something like 4-5 components all running on Zope3, must be highly available, and gracefully handle minor failures, what should I spec in terms of hardware? /me awaits flames ... Thanks in advance for patience, etc. -- Dan Buch SmartEd Services _______________________________________________ Zope3-users mailing list Zope3email@example.com http://mail.zope.org/mailman/listinfo/zope3-users _______________________________________________ Zope3-users mailing list Zope3firstname.lastname@example.org http://mail.zope.org/mailman/listinfo/zope3-users
