In this video, learn about public cloud components.
- [Instructor] So let's now talk about specific cloud solutions. We're gonna talk about public clouds. So public clouds are the clouds that anyone can leverage that are willing to pay a subscription fee. Basically they're for anybody. That's why they're called public. Anybody who has the money can leverage them. The trade off is you're gonna coexist on that cloud service with thousands of other businesses that are basically using those cloud services with you. It's gonna be a multi-tenant application. Keep in mind that the market is changing quickly, and that the cloud providers out there are adding services all the time, and they're shifting to different market needs and market requirements.
You may need to use one type, two types, or all types of public clouds. So you my need Software as a Service, Infrastructure as a Service, Platform as a Service, one, two, or all. Keep in mind your requirements. This is very important as we go forward. This is not about picking the solution of the small business down the street. This is about picking the solution that's right for your small business. So understanding the basics, Software as a Service, finished applications that you rent and customize. Platform as a Service, developer platforms that abstract the infrastructure, operating system, middleware, to drive developer productivity.
Infrastructure as a Service, deployment platform that abstracts the infrastructure. Storage compute, network, databases, things like that. So we have Infrastructure as a Service. It's pretty much what we keep in our data centers. Software as a Service, pretty much at application that's delivered via web browser. Platform as a Service, pretty much development as a service. Platforms we use to development, deploy, test, and move applications out into production. So we have Infrastructure as a Service providers. Examples include Amazon Web Services.
SaaS examples include Microsoft. And PaaS examples include Google, Google App Engine. So, Microsoft typically is not top on the list as a SaaS provider, but they provide Dynamics which is a financial system that they deliver as a SaaS. Amazon Web Services, probably the premier Infrastructure as a Service provider. And Google PaaS system being App Engine, which allows you to provide a platform for building deploying applications.
