Hello

Cloud computing is a very generic field. I am not aware of any single course or training that will make you a cloud-expert in a short time. Even if it could, every vertical expertise has a shelf-life. Therefore, the trick is to develop core skills which can be utilized in diverse areas, and thus keep you relevant and in demand for a long time.Here are some skills which you may consider developing/sharpening to improve your prospects in cloud computing and many varied disciplines:

Database skills: Databases are hosted on cloud platforms and are increasingly accessed by enterprises for information and insights on the move. The ability to store, access and manage data will be very useful. Learning database languages like SQL, MySQL, MongoDB and Hadoop will be a distinct advantage.

Programming skills: Cloud based applications and programs are essential to enterprise mobility and an ability to build and deploy these is a highly coveted skill. Languages like PHP, Java, .Net, Perl and Python would be useful to master in a cloud based world.

Linux: Linux is the preferred operating system for cloud based applications. Therefore, skills in Linux system administration will be a definite advantage

.Iterative or Agile Development: Software development lifecycle must factor incremental requirements and a dynamic environment, which is best accomplished using the iterative or agile methodology.

Security and Privacy: This is one of the most fundamental requirements for cloud-based programs and data. With advanced and persistent threats evolving, this is an ever growing field and a diploma or certificate from a reputable institute will give you a badge of distinction.The good thing is that there are great courses available in each of the above and it is neither too expensive nor overly time-consuming to acquire.

These skills will provide you a platform for not just cloud computing but other new technologies as well, with incremental effort.

I hope it will help you
Good luck...
