1. Request for a foo.com arrives to ARR/Load Balancer

2. ARR gets info from Runtime DB about foo.com and determines which Web server(s)) should host the site.

(Antares is actively monitoring all Web Servers in the farm)

3. ARR forwards request to the designated Web Server

4. Web Server provisions site * de-provision inactive sites

5. Web Server executes request accessing site’s content and site’s DB

Request Process Flow – Inactive Site (Cold Site)

1. Request for a foo.com arrives to ARR/Load Balancer, which already “familiar” with foo.com

2. ARR “remembers” foo.com and route the request to the right web Server(s).

* Subsequent requests to this site get routed to a Web Server that has the site provisioned.

3. Web Server executes request accessing site’s content and site’s DB
