A kernel upgrade is a process of updating the core component of a Linux operating system that manages the hardware, memory, processes, and drivers. A kernel upgrade can improve the performance, security, and compatibility of the system, but it can also introduce errors if some modules are not compatible with the new kernel version. Modules are pieces of code that can be loaded and unloaded into the kernel to provide additional functionality or support for specific devices. If a module is not compatible with the kernel, it can cause crashes or instability.

RTO (Recovery Time Objective) is a metric that measures how much downtime an organization can tolerate during an unplanned outage before it affects its business continuity and reputation.

RTO helps to define the recovery strategy and the resources needed to restore the normal operations as quickly as possible. Verified References: [RTO vs RPO]

This way, the software vendors can charge more for software that runs on servers with more processing power1
