As a Dev, you may have come across the terms web server and web hosting before. Most likely, you have a vague idea of what they mean, but not enough to confidently explain them. In this article, we’ll break down the concepts behind web servers and web hosting in simple terms, with a focus on how they relate to website development and management.
What is a Web Server?
At its core, a web server is a computer program that serves HTTP (Hypertext Transfer Protocol) to client computers that request it. A client computer could be any device that has an internet connection and a web browser, such as a computer, mobile phone, or tablet. The web server responds to client requests by sending back HTML (Hypertext Markup Language) documents to be displayed in the client’s web browser.
Web servers are typically used to host websites, but they can also be used for other purposes such as file sharing or email management. A web server can be either hardware, software, or a combination of both. It is important to note that online businesses, organizations or any other users who want to have their website published on the internet require the services of a web server for their website to be accessible online.
The Function of a Web Server
When a client computer requests a website from a web server, the server receives the request and responds by sending back the files that make up the website. These files could include HTML files, JavaScript, CSS, and media files such as images and videos. The web server sends these files back to the client computer as a response to the client’s request. This happens in real-time and is what allows us to browse the internet and access websites.
Web servers are built specifically to handle HTTP requests and responses. They are designed to be fast, secure, and reliable, and have features such as caching, compression, and load balancing to help improve website performance and uptime.
Types of Web Servers
There are many different types of web servers available, but the most popular ones for web hosting are Apache and Nginx. Apache is free and open source software that has been the most widely used web server for many years, while Nginx is a newer web server that is gaining popularity for its speed and scalability.
Other web servers include Microsoft’s Internet Information Services (IIS), Google’s GWS (Google Web Server), and lighttpd. Each web server has its strengths and weaknesses and is used for different types of websites and applications.
What is Web Hosting?
Web hosting is the service of providing storage space, bandwidth, and other resources that websites need to function on the internet. Web hosting providers lease hosting space to website owners, allowing them to store their website files on servers that are connected to the internet.
Types of Web Hosting
There are several types of web hosting available:
Type |
Description |
Shared Hosting |
Multiple websites share a single server and its resources. |
Dedicated Hosting |
A single website has access to all of the server’s resources. |
VPS Hosting |
A virtual private server provides a dedicated space on a shared server. |
Cloud Hosting |
Several servers work together to provide resources and redundancy. |
Choosing a Web Hosting Provider
Choosing a web hosting provider involves considering factors such as price, performance, reliability, and support. Some providers offer additional services like website builders, SSL certificates, and domain registration.
It is important to choose a hosting provider that can meet your website’s specific needs. For example, if your website has a high traffic volume, you may need a hosting provider that specializes in scalability and performance optimization.
