Open Source Summit + Embedded Linux Conference + OSPOCon 2021

You probably have at least a vague idea about what the cloud is, but feel intimidated by important-looking diagrams with lots of boxes and even more arrows pointing arbitrarily from one to another? Terms like provisioning mode, whatever as a service, infrastructure, or resources confuse you since they appear to mean something different in this context? You wonder if and how different types and brands of clouds distinguish each other? This session is meant to clarify a few concepts for users with some technical background, but who are new to the cloud business and plan (or have) to deal with the cloud as a user. It explains the most important terms and presents real-world examples. Cloud computing is not just a technology, it is an attitude. The session explains its important main concepts: What is the role of Infrastructure as in "as a service"? What do you mean a with a resource? What is a service, and how can I talk to it via an API? Why are services often grouped into categories? We will cover the most important resources for servers, storage, and networks and drill a bit into their relations. How can you be sure your resources are private for the eyes of the other tenants of the same cloud service? Why are authentication and authorization so important?
