What Is a Headless Server and Reasons of building headless server – Guide
A headless server is a computing device with no local interface designed to provide services to other computers and their users. In this context, headless basically means that the computing device has no monitor or peripheral devices like keyboard and mouse. Headless systems can be operated largely autonomously or remotely, depending on the type of device. Servers in large data center environments are often headless.
A corporate data center can have hundreds of servers in a rack, each the size of a pizza box. Pizzabox servers are horizontally arranged rectangular cabinets that are usually installed in a rack with similar servers. Not every computer system needs a monitor, keyboard and mouse. Many computers are servers designed for remote access.
Data centers are full of “rack-mounted” computers that accommodate as much computing power as possible in the smallest of spaces. You save space, electricity, and money by not having to connect each server computer to a separate monitor. Headless systems are not just for data centers. For example, you can host a media server on an old computer you have so that you can stream media from any device on your local network. Once that’s done, you can simply remove the monitor, keyboard and mouse from the media server computer – after all, they can only be accessed over the network. You can store and operate your server PC anywhere in a closet without having to sit down. You now have a headless server.
Reasons to build a headless server
Headless servers are not intended for editing spreadsheets, watching YouTube or playing games. Headless servers are created to perform certain operations assigned by the developer. From managing databases to hosting websites, headless servers do it all.
Cost benefit
If you want to host a website on your own computer, you can do so by following this guide. What if you need to host multiple websites and separate computers handling your databases? You will have to buy more computers, and depending on the size of the traffic, you may have to spend thousands of dollars.
There is no need to buy separate computers as modern technology easily creates multiple headless servers on a single physical computer. But a headless server can save you a lot of money. As needed, you can add more features in the future like storage, memory and upgrade CPU and network, etc.
The headless server is light
Our everyday computers have dozens of unnecessary services running that slow down the computer’s performance. While headless servers only perform specific operations, these servers only run the services/applications necessary to perform those operations. Currently, all popular operating systems provide images to run a server without peripherals. These images are lightweight and offer excellent performance.
virtualization
Virtualization makes it possible to run hundreds of servers headless on a single physical computer. These virtual servers are well integrated into the environment and comfortably share server resources. It’s like sharing a giant room with virtual walls, and each one has its own room. As our business grows, we can add more features to our computer.
Docker is the most popular platform as a service that allows its users to deploy software in packages called containers. Docker has a huge repository of containers designed to handle (specific) tasks. To learn more about Docker and how to deploy docker containers, read this article.
easily manageable
Another benefit of using headless servers is that they are easy to manage. Administrators can automate various system tasks so they can easily capture system-wide and potential incidents within the system.
Kubernetes is a popular open source platform originally developed by Google for managing containerized workloads and services. When it comes to handling these services, Kubernetes is the best for it. With Kubernetes, you can easily scale your system, avoid downtime, and automatically recover from incidents.
