A web server helps store and deliver the website’s content whenever the web browser makes a request. This content includes images, text, and informational data and videos, depending on the request type. The web browser you are using to make a request will be sent to the webserver of that website. It may occur whenever a user clicks the URL or downloads any document via the browser.
This article highlights the basic concept of a web server, how it works, the uses of web servers, and web server security practices.
What is a Web Server? [Purpose of Web Server]
A web server can be hardware or software that relies on the HTTP request sent by various clients connected to the network to get some information. The primary purpose of the webservers is to provide the requested data in the form of any images, text, or video displayed on the web browser that several clients are accessing. Besides supporting HTTP, web servers support SMTP and FTP, mainly for transferring files, storing data, and emailing.
The transfer only happens whenever the web server’s hardware is connected to the internet and helps exchange the data between various devices. The web server’s job is to manage what content is accessed by the user. There are multiple filters and limitations to access the data on the internet. You can access the data if you are an authorized user of a particular server. The webserver works on the client-server model for displaying the information. Any website must have the webserver software for hosting sites.
How does Web Server Works?
To access any website on the internet, you need to provide the URL of that website on the web browser. This request is then sent to the webserver to get the required data. The web server then processes the request, sending the requested data back to the client’s machine. The software part of the webserver consists of multiple components, with one HTTP server understanding the URL and the HTTP.
The web server’s hardware will help store the web server software and the files related to the website that has been accessed. With the help of a web server, you can even host various websites.
Features of Web Server
Below are web server features that you can leverage and use in your daily life, even while browsing through browsers.
- Web server helps in supporting large data storage, thus handling various websites.
- It allows you to set up log files on the webserver to troubleshoot any errors.
- It also helps manage the bandwidth that regulates the incoming traffic to the webserver avoiding downtime for any website.
- You can even create FTP websites as web servers help move the data from one site to another without any effort.
- It even allows the configuration of websites.
- It helps create virtual directories that can be mapped to physical directories.
- You can even set the customized error page with a meaningful message like the 404 page not found to help the users get to the error's root source.
Advantages of Web Server
Here we have listed the benefits of web servers.
- With a web server, you can get the necessary information to communicate with the hosting provider.
- It helps manage the download speed for any web-based application and improves performance.
- It helps provide permission for fixing the broken links and viewing URL construction.
- It ensures transparency while making transactions between your website and the server.
- It is controllable and flexible.
- It is secured as they are stored in protective infrastructure.
- It helps in handling various applications.
- Also, you can customize the web server as per your requirement.
Disadvantages of Web Server
- You may find the webserver more expensive than the electronic web hosting practice.
- It is sometimes challenging to customize the hosting service on the webserver.
- During high traffic, there may be a server crash situation.
Uses of Web Server
In general, a web server is just a part of the whole internet. Below are some uses of the webserver.
- It helps in sending and receiving emails.
- You can even use a web server for downloading the FTP request.
- It helps in building and publishing various websites.
- It helps support customizable server-side scripting as per the client’s requirement. This script only works on the server machine.
What is the difference between dynamic and static web servers?
There are two types of web servers: dynamic and static.
1. The static web servers are fixed where the content cannot be changed or updated. It has HTTP software and a computer. It is considered static because the server sends the requested file as it is present to the browser.
2. The dynamic web server consists of the web server and the software, like the database and the application server. This is considered dynamic because the application server sends the updated files before they are sent to the browser.
Best Web Server Software List
Below are the most commonly used web servers available in the market.
1. Apache HTTP Server
Apache Software Foundation has introduced this software, which is a free and open-source web server. It shows compatibility with operating systems like Windows, Mac OS X, Unix, Linux, Solaris, and others; to use it, you will require an Apache license to use it.
2. Microsoft Internet Information Services (IIS)
Microsoft has launched this software for Microsoft platforms, but it is not available as open-source but is widely used.
This is the most popularly used open-source web server is available for administrators. It is widely adopted due to its light resource utilization and scalability. It helps in handling multiple concurrent sessions due to its event-driven architecture. You can even use this software as a proxy server and load balancer.
This software comes with the FreeBSD operating system. It is available as a fast and secure server, ensuring less CPU power consumption.
5. Sun Java System web server
A free web server from Sun Microsystems runs effortlessly on operating systems like Windows, Linux, and Unix. It is well suited for handling medium to large websites.
You can choose any of the web servers available depending on what features they offer you. On what operating system they can run seamlessly, how they handle the server-side programming, ensure security, and many other features.
Web Server Security Best Practices
You can set various security practices around the webserver to make the user experience simple and safer. Below are some examples.
- You can use a reverse proxy specially designed for hiding an internal server.
- You can implement various access restrictions using several processes, such as limiting the access to the web host to infrastructure machines, or you can even use SSH;
- Make sure you keep the web servers regularly patched and up to date to ensure that the web server is not open to malware and potential vulnerabilities;
- You can take measures to implement network monitoring, ensuring that there isn’t any unauthorized activity occurring on the webserver.
- You can even use a facility of firewall and SSL as firewalls that help monitor the HTTP traffic and SSL to keep data secure.
With the help of a web server, you can host a single website or multiple websites on the same underlying shared software and hardware resource, known as virtual hosting. This is what a web server does. Web servers help limit the speed of sending the response to several clients.
With web servers, you will be able to host the websites on the internet, making them accessible to various users connected to the internet. It also allows you to communicate between the web clients and the servers within the local network area. Well, using this article, you will be able to know what a web server is, its advantages and disadvantages purpose, a list of web server software, and other necessary details.
