These days, it's almost all about the cloud—public, private, hybrid, and community varieties—but how much do you really know about these mysterious unseen dimensions? As more and more organizations use or migrate on-premises IT systems and data into cloud environments, understanding the trendy concept has become both necessary and increasingly complex. In this 12-video course, learners are exposed to the basics of this new cloud world, including the four most popular cloud service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Infrastructure as Code. First, you will learn the five primary characteristics of every cloud—resource pooling, self-provisioning, rapid elasticity, metered usage, and broad access. Then examine each characteristic in more detail: learn how to determine when to use a public, private, community, or hybrid cloud; how cloud service models delivered over a network are categorized. The course helps to prepare learners for CompTIA+ Cybersecurity Analyst+ (CySA+) CS0-002 certification exam.
