Module 2: Cloud Computing Basics
Understand what the cloud actually is, and learn the three service models — IaaS, PaaS, and SaaS — by what each leaves you responsible for.
What You'll Learn
- What defines cloud computing, and what changes when computing moves off local hardware
- The real trade-offs of the cloud, including the ones vendors do not lead with
- IaaS, PaaS, and SaaS, and who manages what in each
- The shared responsibility model, and why data is always the customer's responsibility
Real-World Scenario
Lakeside owns a server in a closet. It needs replacing, its backups have not been tested in a year, and its failure stops the practice working. A vendor proposes moving everything to the cloud, and three other vendors all describe their products as 'cloud-based' while meaning three quite different things.
