For obvious reasons, the majority of businesses and organizations are transferring their legacy systems from on-premises to the cloud these days. They also provide DevOps training to improve their employees' knowledge. Furthermore, when it comes to preventing top personnel from being poached, increasing the development experience and maintaining adequate processes and laws has become the major mantra for firms.
Given the foregoing, it's only logical to go for the most widely utilized cloud services (AWS) and DevOps training. To answer the question, it all depends on your current level of knowledge and your educational background. If you come from a non-tech background, I recommend first learning the terminologies and get some basic ideas from some offline institutions.
If you're already in the field and know your stuff, though, there are lots of internet platforms that can help you. Udemy, Coursera, Pluralsight, LinkedIn Learning, YouTube, Scalar Academy, and others are among them.
