Hi Jacques, Honestly I was shocked by this email, I'm working on deploying OFBiz in Kubernetes, are you monitoring me?
In 2010, Kubernetes was quite new and not good enough, now it's the standard on cloud deploy management, and we can support it. Before doing that, we have to answer some common questions in cloud running lifecycle, such as how may instances/requests can share one CPU, how to deliver(create) an instance, how to isolate an instance, how to offline, how to remove, how to online again and etc. Personally I don't think we have to remove current multi-tenants implements, add a SAAS implement would be OK.

Hi, The multi-tenants feature in OFBiz only allows a dozens or maybe even few hundreds tenants, after it begin to be a lot of DBs! I faced that with a startup which wanted to handle thousands, if not millions (actually they failed), of tenants, obviously OFBiz can't do that. I don't break any secret to say that I was working with David (and Andrew) on a project in 2010 when David had to quickly answer to the client's demand who wanted to have tenants. David brilliantly and quickly delivered, but it was only a start. After many improvements, this feature still have some issues https://issues.apache.org/jira/browse/OFBIZ-6066 https://issues.apache.org/jira/browse/OFBIZ-7900 https://issues.apache.org/jira/browse/OFBIZ-6164 https://issues.apache.org/jira/browse/OFBIZ-6065 Also this is somehow related https://issues.apache.org/jira/browse/OFBIZ-6712 And most importantly https://issues.apache.org/jira/browse/OFBIZ-7112 https://issues.apache.org/jira/browse/OFBIZ-7754 I recently read this article https://www.linkedin.com/pulse/architecture-constraints-end-multi-tenancy-gregor-hohpe/ and, after my experiences with multi-tenant as is in OFBiz, it made me wonder if we should not think about how it's done now in OFBiz in 2018 with the clouds being everywhere! Before sending this email, I quickly exchanged with David about how Moqui handles that now. And we are on the same page, see https://www.linkedin.com/groups/4640689/4640689-6180851287941201924 https://stackoverflow.com/questions/41952818/does-moqui-framework-2-0-still-support-mutli-tenency?rq=1 [1] [1] Initially David gave me this link https://www.linkedin.com/pulse/multi-instance-moqui-docker-david-e-jones/ but it seems LinkedIn has lost it, as said in the stackoverflow comment. So IMO why not deprecating the multi-tenants as is now and rather push a multi-instances way? Opinions? Jacques
