[Carbon-dev] Remove multi-instance feature
This is a feature that never gets tested, nobody seems to know how to use it, and it is badly broken. Nobody seems to be using it in the real world anyway. Shall we remove it? We can get rid of the confusing ports-config.xml file as well. -- *Afkham Azeez* Director of Architecture; WSO2, Inc.; http://wso2.com Member; Apache Software Foundation; http://www.apache.org/ * http://www.apache.org/** email: **az...@wso2.com* az...@wso2.com* cell: +94 77 3320919 blog: **http://blog.afkham.org* http://blog.afkham.org* twitter: **http://twitter.com/afkham_azeez*http://twitter.com/afkham_azeez * linked-in: **http://lk.linkedin.com/in/afkhamazeez* * * *Lean .

Re: [Carbon-dev] Remove multi-instance feature
Should we not be using it in Stratos? I've been thinking of trying that as an alternative to using VMs basically .. take a big machine and run a bunch of elastically scaling processes rather than VMs. If its broken of course then that needs to be fixed before such an experiment can be tried. At least it would be a useful research experiment to compare VMs vs. not. In our world we control all the VMs so the security disadvantages of processes is essentially gone IMO. Sanjiva.

Re: [Carbon-dev] Remove multi-instance feature
We have noticed that IO becomes a bottleneck, and this can lead to failure of multiple JVMs. For example, the AS was failing very frequently when the LB and AS instance were running on the same machine. After separating it out, we were able to handle higher loads. In fact, this is how we are planning to setup Mars 1.0. Having the LB worker node on the same instance does not work properly. -- Sent from APD On May 9, 2011 6:02 AM, Sanjiva Weerawarana sanj...@wso2.com wrote: Should we not be using it in Stratos?
