How to self-educate an IT engineer?

Question

IT education

Please tell me the resources (books / channels / articles) on which you can create a self-education program for colleagues. Direction of ACS PCB. The enterprise cannot send to official courses. It is understood that the engineer must constantly engage in self-education.
How it all started:
Management tested colleagues and stated that the weak areas are:

• hardware basics (HP DL360 G6 server)
  
• virtualization (understanding how to correctly configure the hypervisor / allocate resources for the VM)
  
• databases (PostgreSQL - general information, understanding replication)
  
• backup (types / scope)
  
• SCCM (General Principles/Application/Purpose/Fundamentals of Reporting)
  

The task is to develop a program of self-education of specialists (ITR).
Ideally, I'm looking for a set of links to authoritative sources, where the general points on each of the above topics + Best Practices are chewed on the fingers.
Implementation option
The only working option for us is to draw up a program/plan for self-education/development, according to which weekly scheduled meetings with a 15-minute presentation to colleagues are held. From each of the engineers (total 4) one "report" per month.
PS I would be grateful if you suggest other options that have taken root in your teams.

Everything is chewed on the fingers, it just doesn’t happen. It's a lot of work - to write educational materials, where EVERYTHING is clear and CHEWED on the fingers.
But the official documentation is always on the manufacturer's website. She needs to be read.
But if the management itself has tested and made a decision on self-education, and does not allocate a budget for this, then let it not wait for the result. They should have either hired certified employees earlier or set aside a budget for training.

Answer 2

Uh-uh, it's always better to trust the professionals.
If the leadership does not understand this ... Then this is the problem of the leadership.
And so, everything is simple.
Plan in your work schedule for 1-1.5 hours a day for "self-education".
That's the whole program that you can professionally compose. :-)

Answer 3

Slightly off topic.
We had such an attempt, nothing came of it. If the engineer himself does not study, then it will be difficult to force him. In general, an engineer who stops learning is bad.
And if the management also decides to conduct tests for professional suitability every few months (as it was with us) and “punish” people who passed poorly, then the people will generally begin to scatter.
