Cloud and mobile technologies
Cloud Computing Model (1)
Cloud computing services are built on layers
Each layer performs a specific function
Like many services, the infrastructure provides the foundation. Without a strong foundation, any service will collapse. The foundation includes the hardware for moving, storing, and processing the data. Let’s define each of these layers that make up the cloud.
Cloud Computing Model (2)
The foundation layer that makes up cloud computing is infrastructure as a service or IaaS. Network architects and engineers construct this layer for the cloud computing services to use. The next layer is platform as a service or PaaS. Application developers use this layer to develop software services. Software as a service or SaaS uses the platform and infrastructure services to run applications, which you use as the end user.

Data Centers (1)
Data centers make up part of the cloud computing infrastructure.
A data center is a large group of networked servers for storing, processing, or distributing data.
Data Centers (2)
It is a physical place that houses a computer network's most critical systems, including backup power supplies, air conditioning, and security applications.
The next layer is PaaS. But, what is a computing platform?
A computing platform is an environment in which a piece of software is executed
It could be
The hardware, in the case of an embedded system
The operating system (OS) that hosts an application
An application, such as a web browser that runs web-based software
Software developers commonly use a computing platform for developing or deploying their software.
