Using Podman on RHEL for Real Time
Red Hat News, Thursday, November 23,2023
A real-time operating system (RTOS) is like a skilled orchestra conductor. A conductor coordinates and manages the timing and synchronization of many musicians and instruments to create a harmonious performance.
An RTOS orchestrates the timing and execution of multiple tasks and processes in a computer system so that critical operations are completed precisely on time. This is known as determinism, and it's the most important feature of RTOS because responses to inputs need to be returned within a set maximum time frame, usually measured in micro seconds.
If you're using or looking into an RTOS for a project that demands deterministic results, where there is an absolute limit on response time, you might find some vendors of hard RTOS to be expensive. Hard RTOS is used in avionics, nuclear control systems, and some defense applications. Alternatively, a soft RTOS fulfills a requirement to respond deterministically, with the quickest responses tied directly to the level of tuning performed with hardware and software.
