Here are the implications: - the hardware is your single point of complete failure - the whole machine would share its performance among native and virtual instances, so staging and development will have an impact on the production instance - if you production instance gets compromised, its not far for intruders to staging/development - the other way round (atack on zope instance, then attack on vm to reach the host) is pobably not very much harder
why don't you just run 3 zope instances on the host? If its a pure zope application, then they won't interfere with each other. Although you can't upgrade zope idependently then, its in any case better resource-wise. --knitti _______________________________________________ Zope maillist - [email protected] http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
