Week Two

This week I was having trouble differentiating the different types of "as a Service" options, so I decided to do some research. I found some great websites that break down the different types of  cloud models into easy to understand sections. I combined what I read from these sources with the book.

Here is an overview of what I learned:

SaaS:
- Software as a Service provides complete applications to a cloud’s end user.
- SaaS options are prebuilt and cannot be changed beyond personalization.

PaaS:
- Platform as a Service expands an organization's capability to customize application development in the cloud.
- PaaS comprises the environment for developing and provisioning cloud applications.

IaaS:
- Infrastructure as a Service is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components.
- IaaS allows a client almost complete control over applications, languages, and fundamental services (databases, storage, and networking).

 XaaS:
- Everything as a Service combines or blends traditional storage with cloud resources.
- Other examples of XaaS include storage as a service (SaaS), communications as a service (CaaS), network as a service (NaaS) and monitoring as a service (MaaS).
