Cloud... Just Someone Else's Computer

Cloud is just someone else's computer, that's a statement that has been around for a while, but what does it mean? In this talk we'll see with practical examples how different public cloud services are working under the hood, and why this statement is very true. How does a serverless public cloud service actually work on the bare-metal level? What happens behind the web user interfaces/consoles? The presentation will go through such cases on AWS, Azure and GCP which will, hopefully, inspire your security research, or even security architecture and engineering if you are designing or developing something similar for your own organization. The aim of the talk is to give both security researchers, architects, and engineers a different perspective and remove some of the ambiguity of public cloud through real-world examples on the most widely used public cloud providers.
