1.3 Cloud Models

What do you need to consider when you want to deploy a cloud-based application?

Who will be accessing the application and from where

What are the three types of cloud models?

Software as a service (SaaS), Infrastructure as a service (IaaS), and Platform as a service (PaaS)

How does SaaS work?

After you log in on a browser, you have access to the application. Someone else wrote the application, manages it, and your data is stored somewhere within that application.

Benefit of SaaS?

You don’t have to do anything to be able to use the application. No local installation, no managing/updating the software

What are examples of SaaS?

Google Mail, Office 365

When is IaaS good?

When you want your own application, to deploy/manage your own data, and all you really need are the computing resources to be able to run that application

What is another name for IaaS and why?

Hardware as a service (HaaS), you’re outsourcing your equipment

What are you responsible for in an IaaS cloud model?

Installing/managing the software, managing all the data associated with it, security measures

What is an example of Iaas?

A web server provider where you can buy time on a particular web server and they make that server available to anyone on the internet

How does PaaS work?

No servers, no software, no maintenance team, no HVAC. Someone else handles the platform, you handle the development/customization of the application

What do you not have control over in a PaaS cloud model?

No direct control of the data, people (trained security professionals are watching your stuff), or infrastructure
