> # About Bootstrap Module
> Bootstrap is a mechanism to manage how microservics interact with external services. When running a microservic in a Cloud Native enviroment, it will interact with many external services, like service center, config center, an APM service to report tracing data, a dashboard service to report health data, etc. Bootstrap manages the meta data of these services. Bootstrap queries the addresses , the parameters, the authentication information of these services and so on.
> Bootstrap is some kind of service like service center, they are differ from two aspects:
> 1. All microservics will report their information to service center. But Bootstrap acts as a management system and knows the meta information in deploy time. 
> 2. Service center provide some other functions like instance management and heartbeat, But Bootstrap only provide metadata query services and it is simple.
> Bootstrap does not provide a management service, it providers the interface to interacts with management service. Service Providers can implement the interface.
> They are some design constraints need to be considered when implment Bootstrap interface:
> 1. Bootstrap can only read configurations of environment, microservics.yaml. It can not read dynamic configurations.
> 2. Bootstrap is initialized before bean initialization.
