All of the above analysis helps in decision making for future development.
CLOUD COMPUTING STRATEGY PLANNING
The strategy establishment is based on the analysis result of the above step. In this step, a strategy document is
prepared according to the conditions a customer might face when applying cloud computing mode.
Cloud Computing Tactics Planning Phase
This step performs analysis of problems and risks in the cloud application to ensure the customers that the cloud
computing successfully meet their business goals. This phase involves the following planning steps:

Business Architecture Development

IT Architecture development

Requirements on Quality of Service Development

Transformation Plan development
BUSINESS ARCHITECTURE DEVELOPMENT
In this step, we recognize the risks that might be caused by cloud computing application from a business
perspective.
IT ARCHITECTURE DEVELOPMENT
In this step, we identify the applications that support the business processes and the technologies required to
support enterprise applications and data systems.
REQUIREMENTS ON QUALITY OF SERVICE DEVELOPMENT
Quality of Service refers to the non-functional requirements such as reliability, security, disaster recovery, etc. The
success of applying cloud computing mode depends on these non-functional factors.
TRANSFORMATION PLAN DEVELOPMENT
In this step, we formulate all kinds of plans that are required to transform current business to cloud computing
modes.
Cloud Computing Deployment Phase
This phase focuses on both of the above two phases. It involves the following two steps:

Cloud Computing Provider

Maintenance and Technical Service

Cloud Computing-Technologies
T
hereare certain technologies that are working behind the cloud computing platforms making cloud
computing flexible, reliable, usable. These technologies are listed below:

Virtualization

Service-Oriented Architecture (SOA)

Grid Computing

Utility Computing
Virtualization
Virtualization is a technique, which allows to share single physical instance of an application or resource among
multiple organizations or tenants (customers). It does so by assigning a logical name to a physical resource and
providing a pointer to that physical resource when demanded.
