Hey devRant people !

How are you ?
I’ve a question, do you know a website like FrontendMaster, CloudAcademy or LinuxAcademy but ... for backend stuff ?

EdX, Udemy and all are very good but I would like to find a platform specialized in this topic.

LinuxAcademy - is it worth the expense? Does anyone have a resource suggestion that costs less or free or has better material?

Do linuxacademy certificates mean anything? I mean do they valid?

Does anyone know what learning path or courses to take if I wanted to train for Devops role using LinuxAcademy? Or does anyone have a roadmap as to what I should learn (in LinuxAcademy and outside) before I can start applying to companies? Currently a developer with ~2 yrs of experience and looking to shift.
