What Are The Different Layers Of Cloud Computing?

The Cloud computing comprises of several layers of elements. It starts from the fundamental physical layer and the network layers. There are three layers of cloud computing services which are as follows:

Infrastructure Cloud: This includes the components which are important for running the applications and the storage of data. The virtual servers are made to run these applications. The virtual abstraction is also used for managing the server and the storage as logical rather than any physical entity. Under this the virtual storage pools are made to existing as well as new data.

Content Cloud: Implements indexing services and metadata in order to provide the abstracted data management. The aim of this layer is to derive data from the applications so that the diverse applications can be used to access similar data. It also transforms the data into the object and avoids any interference to the data, the content may be gone but the data remains to exist.

Information Cloud: under this layer the access is abstracted from the layer to the clouds. As it allows the user to access the data in the database via mobile phone, every bit of the data is abstracted here under.

The three main layers of cloud computing are : SAAS, PAAS, IAAS.
SAAS (Structure as a Service): SAAS providers offer an actual level to end users.
PAAS (Platform as a Service): PAAS providers offer a managed enviorment in which to run your application rather than hardware.
IAAS(Infrastructure as a Service): IAAS providers offer low layers abstraction of physical devices.
