Subject Re: [jira] Commented: (JAMES-1074) Align packages hierarchy of the services
Date Thu, 28 Oct 2010 06:47:06 GMT
Hi Simon,

If you look for example to the ActiveMQ JMS Queue used by james, we may 
imagine the bus can deployed on different servers, with each servers 
serving some incoming smtp requests, and injecting the mails in the 
distributed JMS queue.
We could also imagine create some james images to be deployed in EC2.
When james will be OSGIed, it could be deployed in a distributed OSGI 
solution (newton,... or whatever).

So yes, I can be with you about  the notion of "Cloud of components" or 
"Component Cloud" for james.
I suppose this kind of topic have already been discussed around.
For james, I would see (thinking loud) something like MaS (Mail as a 
Service) in a future.

Back to basics, we are still willing to find a place/name for the 
SpoolManager and JamesServer.
You can read more on James architecture and development on these very 
alpha pages:
