Configuration lookup service

view full story

http://serverfault.com – I have a server cluster and each instance needs to have some sense of the overall system state. Basically what I need is a lookup service that... stores basic service configuration, such as database master/slave addresses etc. allows clients to register their information (ip, role, state, etc.), so other clients can find them. Since I'm new to server development/management, where should I start to look? What technologies are appropriate? Is there a better solution to solve this? (HowTos)
