Firewall Configuration

I am supposed to setup a Cisco ASA firewall to receive traffic from 3 separate network on the outside interface and those networks need to go through in three separate instance. I believe it has a name, I don't know it. I'm looking for help to configure this. Any detailed step-by-step or any previous help of it has been done would be appreciated.

The idea is to create a context for each one of the 3 networks to operate as if each one is on a separate firewall, e.g. being separate. I'm glad you mentioned failover, that was going to be my next research point as well as how to back up the configuration of the firewall in such an environment.

Thanks very much this is great info. I know I will have to configure those vlans on my switches as well, but As you mentioned you have to setup an IP address for the outside and inside interface. Can I also do all other firewall functions such as NAT? and I were to want want to run a routing protocol such as OSPF how would that be done?
