My answer is given below:


Cloud computing is a business model and not technology. That means there is no breakthrough hardware or software technology that suddenly has made the cloud possible. Rather it consists of well-known technologies and concepts, put together in a new way. These technologies are known as layers. By adding them all together we get the package that enables the cloud.

Let’s take a look at the different layers of cloud computing:


Infrastructure as a Service (IaaS)

The basic layer of the cloud is the infrastructure –IaaS (Infrastructure as a service). This layer is basically hardware and network. What distinguishes this from a regular server or hosting company are mainly two things: scalability and virtualization.

What is most important is scalability. The true IaaS vendors are scaling their IaaS layer into such huge quantities that the marginal cost of adding more GHz, GB, storage, and so on, are converging towards zero.

2  Platform as a Service (PaaS)

The second layer of the cloud is the platform – the PaaS (Platform as a service). The platform layer provides resources to actually build applications. In combination with IaaS, PaaS provides the ability to develop, test, run, and host applications.

The platform layer opens up for third parties to add their software (or integrations) to a cloud service. An example of a well-known PaaS is Microsoft Azure. This platform provides developers with swift access to a full development and deployment environment and even let you host the application you are building.

Software as a Service (SaaS)

The third cloud layer is the actual Software – the SaaS (Software as a service). SaaS has been used for many years, but in a Cloud setting, it is the layer in which the user consumes the offering from the service provider.

The SaaS layer must be web-based and hence accessible from everywhere and preferably on any device. The key is to understand that it makes no sense to ask whether a service is cloud or SaaS, as SaaS is a layer in the cloud stack.

Business Process Outsourcing (BPO)

The top layer of the cloud is Business Process Outsourcing (BPO). As BPO certainly is not technology, there are discussions about whether BPO can be regarded as a cloud layer. But, as mentioned in the beginning of the article, the cloud is all about business models, not technology.
