External Configuration Store Pattern

Local configuration issues

Some config require the application to be redeployed

Single application config that must be replicated across different apps or instances of same apps

> Store the config file in an external storage

> Provide an Interface to read and update configuration settings

> Store should provide:

- consistent and easy to use access

- information in structured and typed way

- user authentication functionalities

- storage for multiple versions of the config

- optionally a caching mechanism
