Throttling is a process to rate-limit requests from a particular IP. This can be used to prevent DDOS attacks as well. For throttling, Laravel provides a middleware that can be applied to routes and it can be added to the global middlewares list as well to execute that middleware for each request.
18. 16:47 - What are facades?
Facades are a way to register your class and its methods in Laravel Container so they are available in your whole application after getting resolved by Reflection.
19. 18:28 - What are Events in Laravel?
In Laravel, Events are a way to subscribe to different events that occur in the application. We can make events to represent a particular event like user logged in, user logged out, user-created post, etc. After which we can listen to these events by making Listener classes and do some tasks like, user logged in then make an entry to audit logger of application.

Request validation in laravel can be done with the controller method or we can create a request validation class that holds the rules of validation and the error messages associated with it.
24. 30:22 - What is a Service Container in Laravel?
Service Container or IoC in laravel is responsible for managing class dependencies meaning not every file needs to be injected in class manually, but is done by the Service Container automatically. Service Container is mainly used in injecting class in controllers like Request object is injected.
25. 34:18 - What is a Service Provider?
A Service Provider is a way to bootstrap or register services, events, etc before booting the application. Laravel’s own bootstrapping happens using Service Providers as well. Additionally, registers service container bindings, event listeners, middlewares, and even routes using its service providers.
26. 35:53 - What is the register and boot method in the Service Provider class?
The register method in the Service Provider class is used to bind classes or services to the Service Container. It should not be used to access any other functionality or classes from the application as the service you are accessing may not have loaded yet into the container.
