Do cached services use an instance?

Discussion created by smenefee on Apr 24, 2013
If you have the minimum number of instances set on a cached service to 0, and nobody makes any queries against that service (meaning it's for display purposes only), will the number of instances ever go more than 0?

I'm confused because I have a lot of cached services being consumed by a flex application, but the number of instances running for all of the cached services are always 0 for the cached services I have set to a minimum # of instances to 0.
