Hi Gino,

I guess the deployment of REST based would be atomic and it would be just down to stress testing - I looked at the Google App Engine and its pretty similar.

What I was just wondering about is in a typical deployment you have a wotaskd sitting on a server(s) with instances.

I was more just interested in trying to visualise the routing of requests across a set of servers where there are more than one WOAdaptors running.

What would split the requests and keep routing them to the correct instance?

You can use session affinity on an ELB to achieve this:

http://docs.aws.amazon.com/elasticloadbalancing/latest/classic/elb-sticky-sessions.html

That solves the problem for a static appserver topology. If your app is session-based, I’m not sure you’re going to be able to use more interesting features like auto-scaling in the absence of reliable session persistence. Report your experiences back to the list if you can!
