As we know that operating system (OS) is the system software that manages computer hardware and software resources and provides common services for computer programs. Basically, all computer programs, excluding firmware, require an operating system to function.
Nowadays, there are many types of OS such as General Purpose operating system, Time Sharing operating system, Distributed operating system, Real Time operating system and so on.
For time-sensitive mission-critical application, the principle mission is to complete the task on time and in predictable manner. Only Real Time operating system can ensure that task will be completed execution in a guaranteed amount of time.
Current SLERT12 SP2 inherits hardware enablement and new features of SLES 12 SP2 kernel. SLERT team delivers enhancements to the real time scheduler and more fine grained locking mechanisms, improving performance and scalability.
The most of that SLERT 12 SP2 also supports virtualization as below:
1. All SUSE Linux Enterprise supported guests are supported on SLERT for non-time sensitive workload.
2. Support docker containers and real-time capabilities within SLERT guests.
