## Before getting started

<br>

### Web

* The Web is one of the **communication protocols** that operates on top of the Internet network system
* The reason the Web is used synonymously with Internet is because the Web is the most successful Internet service!

<br>

### Server & Client

* The `Client` requests information, and the `Server` provides information!

<br>

### HTTP

* A protocol (agreement) for exchanging information between a Web Server and a web client
* It defines the rules for how a `Request` should be made and how the `Response` to it should be handled

<br>

### Web Server

* Also called `HTTP Server`
* Refers to the software that provides information on the server side
* A well-known web server is `Apache`
* `NGINX` has been gradually rising since 2007!

\ <br>

## NGINX

* A **next-generation** web server!
  * It is putting the brakes on `Apache`'s dominance!
    * I like it...
* A web server with an **asynchronous event-driven** architecture designed for **scalability** to handle websites with heavy traffic
* *It can serve data **faster** with **fewer resources**!*
  * A **lightweight** web server

\ <br>

## NGINX vs Apache

* It is no exaggeration to say that `Apache` is a living witness of the Web
  * It is no exaggeration to say that `Apache`, which is **Open Source** and **free** to use, is supporting the Web!
* But, `Apache` is software that was created a long time ago
  * The requirements of the era when Apache was created may no longer be valid in the current era
* `NGINX` is a web server created in response to the demands of a new era
  * All development goals are focused on **high performance**
  * Features that are rarely used were boldly excluded

### Conclusion

: In most situations, `NGINX` shows better performance than `Apache`!
