Facades is a design pattern, about IOC container I wrote an article here, http://segmentfault.com/blog/zhaoyi/1190000002411255

The IOC container in Laravel is used to parse instances of classes. Why parse it, because the class has dependencies.
Class binds the IOC container, it is possible to use dependency injection to make the instance easier to obtain.

Facade is a simpler method of parsing a container instance, and its nature is just as convenient as type-hint injection.
