Reviving the multi-tenancy issue

[estaylorco]

Hello All,

I've been reading the forum posts on multi-tenancy and I have what might be silly question: What about running a single Tomcat server per tenant that, in turn, connects to a distinct database?

I've run two dozen Tomcat servers on the same physical machine in the past.  Activiti appears to have a very low memory usage profile.  On a Small, Reserved AWS instance, one could probably handle 25 tenants running 25 Tomcat servers.

Do you think this scenario is feasible?

Sure, this is off course feasible, if you approach activiti using the REST-api. if you have a single point of access (for all tenants- that uses the Java API, that's not possible. 5.15 contains tenancy-capabilities, having tenant-specific deployments, process-definitions, …

Since we will be accessing the engine from an ASP.NET server, REST is the only way we'll be going.  We're developing a SPA (Single-Page Application) using Durandal against Web API 2.0 and SignalR server-side.

It's great to hear that 5.15 will offer multi-tenancy.  Any idea on the time frame?  We have a lot of other work to do and could easily triage the workflow portion in anticipation of 5.15.

Thank you.

Activiti 5.15 will be available mid to end February.
