```
public interface WebServer
```
Represents a immutably configured WEB server.
Provides basic lifecycle and monitoring API.
Instance can be created from Routing and optionally from Config using create(Routing), create(Routing, io.helidon.config.Config) or builder(Routing)methods and their builder enabled overloads.
