The 2nd top hit for 'Cloud Computing' on Google says 'Cloud computing is a general term for the delivery of hosted services over the internet.' Unfortunately, that definition is completely wrong. This course is designed to clear up the many misunderstandings about Cloud Computing and to give you a crystal clear and easy to understand explanation of exactly what it is, how it works, the different options available, the advantages provided and how much it's going to cost. And I'm not just going to give you the theory, I'm going to show you practical examples which you can follow along with yourself so you'll understand exactly how Cloud Computing works in the real world. I start off with a review in Module 1 of the traditional deployment models of On Premises and Colo so you can understand how Cloud changes things, then explain how server virtualisation revolutionised data center design and paved the way for Cloud.
