I took this course a while back, and I thought I'd talk a bit about it.

It's a good basic introduction to cloud computing, allowing you to dip a toe into a number of areas and understand the fundamentals. It explores compute (EC2), storage (S3), a bit of networking and security. You dive into the various "aaS" bits, understanding the difference between Platform (PaaS), Software (SaaS), Network (NaaS) and Infrastructure (IaaS). It talks about how the Amazon platform (AWS) approaches availability by explaining Availability Zones (AZ), which are basically redundant datacentres within a region. Each region is made up of 2 or more AZs, and are located geographically.

It explains some of the cost advantages of cloud computing, and some of the tradeoffs you make. It even talks briefly about Lambda, which is Functions as a sevice (FaaS) also known as Serverless.

This course allows you to be able to wrap your head around the cloud, even if it's a bit Amazon centric. At an estimate of 25 hours, it's decently long and insightful. While I had lots of VM experience before this course, it did help to fill in some blanks in my knowledge.
