Section II
Road to Cloudware
Enterprises require much more agility and flexibility than what could be
provided by EAI solutions. SOA exposes the fundamental business capabili-
ties as flexible and reusable services—the services support a layer of agile
and flexible business processes that can be easily changed to provide new
products and services to keep ahead of the competition.
Chapter 7 presents the basic concepts and characteristics of SOA. Chapter 8
presents the defining architecture of Web Services. Chapter 9 explains the
basic design of an enterprise service bus (ESB), and Chapter 10 introduces
the principles of service composition and the related business process execu-
tion language (BPEL). Chapters 11 and 12 respectively, present two different
service delivery models, namely, applications service providers (ASP) and
grid computing.
In the final analysis, cloud computing is an extension of the network is com-
puter vision, namely, network is service provider.
