Introduction
The second part of this topic provides a general view of Grids and Clouds and a
thorough understanding of what Grid and Cloud Computing are. Topics that are
covered in detail are definitions and classifications of Grid and Cloud Computing,
underlying architectures and components, business models and value networks of
Grid solutions and legal aspects that are important when moving towards Grids and
Clouds. Part II is a rich body of general knowledge on the commercial application
of Grid and Cloud Computing that will be complemented with practical concepts,
experiences and findings from the BEinGRID project in Part III of this topic.
Part II starts with a definition of terms related to Grid Computing and its
commercial application, a classification of different types of Grids, a description of
Grid architectures and an outline of the evolution from Grid to Cloud Computing
in chapter 3. In chapter 4, an understanding of Cloud Computing is derived based
on the review of many definitions provided by industry analysts, academics, and
practitioners. Further, chapter 4 provides a description of different classifications
of Cloud Computing and a comparison of Grid and Cloud Computing. Chapter 5
is dedicated to Grid business models and presents an overview of business models
adopted by Grid application and services providers in the market based on an anal-
ysis of Grid business cases. Chapter 6 explains what a Grid solution is by drawing
upon the concept of value networks. First, different types of Grid market players
and flows between them are generally described. Then, concrete value networks for
different ways how a Grid solution can be offered are examined. The final chapter
of Part II (chapter 7) is dedicated to the most relevant legal issues that a typical
customer should take into consideration when reviewing the terms for the provision
of Grid/Cloud services from a technology provider.
