  1. Difference between Server Update and Upgrade Most of the beginners new to Linux dedicated server get confused about the several new software terminologies. The most confusing words in the web hosting industry are "updates" and "upgrades." Both of them should not be exchangeable since their functions are different and have different meanings and have different effects. Before that, you need to know the working of Linux distributions. The Linux operating systems released under the GNU project consists of a Linux based kernel and various components that work with it. However, the vendor has much necessary software in the installation of Linux server operating systems that you receive after the installation is completed on your dedicated server. Also, you get access to a software repository containing the binary packages the distribution merchant has maintained. Updates and upgrades are the two most important things necessary to perform on time, secure your server, and increase its life and performance. Usually, new people in the web hosting ignore the updates, which leads them to deal with a lot of trouble. Updating your operating system with security patches and upgrading your server operating system version will ensure your server's security and information stored on it. What are Updates? Updates denote the minor fixes to the server core operating system. Usually, these can be security updates or bug fixes. The Linux distribution version will never change. However, some updates may get a release to fix the bugs in the existing operating system. An update may be a single file or may consist of multiple software packages. For a web server, you might have a Linux distribution for the long-term, but the updates are crucial for security reasons to make your operating system stronger and prevent attacks on the server. What are Upgrades? An upgrade is a fundamental system-wide version change; it may be of all the software and applications within your Linux distribution. In an upgrade, your dedicated server may get a new kernel version, libraries, software packages, or may consists of recent configuration file changes. Most of the time, old version packages are not compatible with the new one. Hence, when upgrading your dedicated server, you need to be very careful. Unless it is mandatory to upgrade the server, you should avoid upgrading. Upgrade only when there is a new and stable version of Linux is available. Else, maintain the old version properly with new updates released.
