What is reference model in cloud computing?
The cloud computing reference model is an abstract model that characterizes and standardizes the functions of a cloud computing environment by partitioning it into abstraction layers and cross-layer functions. The three cross-layer functions are business continuity, security, and service management.
What are the various layers in the cloud reference model?
The Model divides cloud-based application architecture into seven layers: Application, Transformation, Control, Instantiation, Appliance, Virtual, and Physical. Each layer focuses IT functionality on supporting a specific area of concern and abstracts details of other layers.

Why do we need cloud reference model?
Cloud Reference Models To achieve the potential of cloud computing, there is a need to have a standard cloud reference model for the software architects, software engineers, security experts and businesses, since it provides a fundamental reference point for the development of cloud computing.
What are the four types of cloud deployment models?
