Are you referring to cybersecurity and cloud computing, specifically Azure and AWS? Could you please provide a few tips on how to get started?
Yes cybersecurity, its huge market in next 5-10 years. I'm not into cloud anymore/now but back in the day I used Cloud guru, don't think its there anymore. I hope someone from here can guide you to find these materials. I can do a simple google search and give but not fair for you, if i don't have an experience on using them ne.
Another mistake that people do is when they get into some certification they will just learn that only. But don't do that. Say you want to be an AWS developer.
Search Jobs for AWS developer in Linkedin --> See the job requirements --> You will see that Job posting says AWS developer with experience on X, Y, Z technologies too.
If you see 20-30 job requirements for the same role, you will know exactly what technologies/framework AWS developers would engage in. So you need to train in those technologies too apart from the certification to properly apply for jobs (and have an advantage over the competition).
This is similar to any role/technology you like to apply not jut AWS. You will also get to know what kind of role you will play with the job description.
