Cloud Computing and Cyber Security are totally different from each other, and we could not compare these two domains with each other and conclude one is better than the other. Each domain has its pros and cons, advantages, and disadvantages, it is you who should decide which suits you based on your interests and passion. Cyber Security is all about securing your system, networks, from threats which may result in a data breach or data theft.
Cloud Computing is the domain, which is responsible for on-demand computing, storage, and other resources needed to maintain a huge amount of data online, without setting up our own datacenters and worrying about infrastructure. We can scale our resources, to match the demand the moment we need.
Both domains are at their peak phase, churning out huge vacancies, and offering high salaries for qualified professionals. So, it boils down to which domain you like to work in and are comfortable in skilling yourself.
