Cloud computing is the latest market-oriented computing paradigm
which brings software design and development into a new era
characterized by "XaaS", i.e. everything as a service. Cloud
workflows, as typical software applications in the cloud, are
composed of a set of partially ordered cloud software services to
achieve specific goals. However, due to the low QoS (quality of
service) nature of the cloud environment, the design of workflow
systems in the cloud becomes a challenging issue for the delivery
of high quality cloud workflow applications. To address such an
issue, this book presents a systematic investigation to the three
critical aspects for the design of a cloud workflow system, viz.
system architecture, system functionality and quality of service.
Specifically, the system architecture for a cloud workflow system
is designed based on the general four-layer cloud architecture,
viz. application layer, platform layer, unified resources layer and
fabric layer. The system functionality for a cloud workflow system
is designed based on the general workflow reference model but with
significant extensions to accommodate software services in the
cloud. The support of QoS is critical for the quality of cloud
workflow applications. This book presents a generic framework to
facilitate a unified design and development process for software
components that deliver lifecycle support for different QoS
requirements. While the general QoS requirements for cloud workflow
applications can have many dimensions, this book mainly focuses on
three of the most important ones, viz. performance, reliability and
security. In this book, the architecture, functionality and QoS
management of our SwinDeW-C prototype cloud workflow system are
demonstrated in detail as a case study to evaluate our generic
design for cloud workflow systems. To conclude, this book offers a
general overview of cloud workflow systems and provides
comprehensive introductions to the design of the system
architecture, system functionality and QoS management.
