Where to store configuration information in large Distributed Enterprise System -


this more of high level question. have large number of applications, many of them distributed (server/clusters) , share configuration parameter.

what way store application specific configuration (preferable in central place) without relying on single point of failure.

for configuration mean things "database server addresses", "web services endpoint", "logging file name" , why not business related constants , parameter. of parameter changed @ runtime application needs able query dynamically these parameters.

i can think of application storing configuration @ local file (forget format) or central database store same.

but ask community if there standards handling configuration of multiple distributed systems.

thanks.

apache zookeeper centralized service maintaining configuration information, naming, providing distributed synchronization, , providing group services.
