Introduction
Greetings tech enthusiasts! If you’re reading this article, chances are you’re considering implementing Ubuntu in your infrastructure. Ubuntu, a Debian-based Operating System (OS), is a popular choice among server administrators. Two flavors of Ubuntu that are often compared are Ubuntu Server and Ubuntu Core. In this article, we will analyze the differences between Ubuntu Server and Ubuntu Core, their advantages and disadvantages, and which one is suitable for various use cases.
What is Ubuntu Server?
Ubuntu Server is a stripped-down version of the standard Ubuntu OS designed specifically for servers. It is optimized for running server applications and comes with a minimal desktop environment, making it lightweight and efficient. Ubuntu Server is known for its stability, security, and ease of use. It is an ideal choice for running web servers, file servers, and database servers.
What is Ubuntu Core?
Ubuntu Core, also known as Ubuntu Snappy, is a minimalistic version of Ubuntu designed for connected devices and Internet of Things (IoT) applications. It is a lightweight, transactional OS, which means it is designed to be used on devices that have limited resources and need frequent updates. It comes with a read-only file system, making it secure against tampering. Ubuntu Core is ideal for running IoT gateways, industrial control systems, and connected devices.
