I need to implement a windows-like service for Linux system. There is C++ code which do a particular job which I want to be run by schedule (every minute).
The service will be always up and running 24h/day, 7d/week and 365d/year and should be highly fault tolerant.
What is the best suitable approach to implement such service? Daemon, Linux service, cron e.t.c or some combination of them?
You normally do that using either a cron job or a daemon, but not both.
That sounds like a candidate for a cron job. If you need to keep a lot of state in between invocations though, a daemon with a 1-minute timer in it could be a better option.
You may like to provide more details on what your application is supposed to do.
