As most cloud platforms, Azure is evolving quite fast. This makes it hard to keep up-to-date and know where you need to focus your energy on. Azure Charts can help. It is a web based application which allows you to see what the Azure consists of and how it evolves. I would specifically recommend to take a look at the Learning section to see what new Learning content got published.
