 I started learning cloud-level technologies two years ago by reading books, joining made-ups, and do hands-on tutorials on my lab environment. I prepared a CKA exam for about six months from newbie and finally got a certificate July 2018. From that, I moved to a new department which deals with cloud-level technologies professionally, and I am an architect there with cloud-level technologies now. I am very enjoying my work with proposing new solutions and help customers who want to change their existing cultures and innovate their business.
