Course Overview
Hi everybody, I'm David Chappell. Welcome to my course, Cloud Computing: The Big Picture. I'm the principle of Chappell Associates in San Francisco, California, and I'm convinced that the rise of cloud computing is among the most important trends of our time. I don't care what your role is, if you work in technology, cloud computing is affecting you. You might write code that runs in a cloud platform like Amazon Webservices, or Assure, or maybe your organization is building a private cloud that you'll need to manage, and whoever you are, I know that you use cloud applications. This course provides a broad introduction to cloud computing, and don't assume that you have any prior knowledge of this topic. The major things I'll cover are cloud applications, which are commonly knows as Software as a service, or SaaS, cloud platforms, and private clouds. By the end of this course, you'll know enough to go deeper, if you choose to, into more specialized cloud topics. You'll also be able to do a better job working with and making decisions about cloud computing. I hope you'll join me to learn about this important topic with the Pluralsight course, Cloud Computing: The Big Picture.

Software as a Service
Most organizations rely on some packaged software. Increasing though, that packaged software is running in the cloud. It's becoming a cloud application. It's becoming Software as a Service. In the diagram that I'm using to organize this course, cloud applications fir right here, and the picture raises an obvious question, doesn't it? The question is, well, what's the big deal? The idea of having applications that run remotely at some service provider, that you access from your organization, is hardly new, been around forever. People have run email servers, SharePoint sites, all sorts of business applications, what's the big deal? How is SaaS different? Well, there are a few answers, but what are most important is this, traditionally when a hoster provided an application, they ran an instance of the application for your organization. In SaaS, that's not typical. In SaaS, applications are generally multi-tenant. Now, that's a fancy word, but in fact, all multi-tenant really means is shared. It means that a single application is being shared but multiple customers, multiple organizations, multiple users. All of them have their own data, and it's the responsibility of the application to keep that data separate and secure, but the idea of multi-tenancy is central to the modern notion of SaaS.
