Grid computing enables the sharing of heterogeneous
resources among different administrative domains
promising unlimited computational and storage power
available on demand. However, Grid applications are
often developed in an ad-hoc manner with little or no
transferability across them. Grid applications not
only need to adapt to evolving standards but they
also need to adjust to a dynamic environment in which
resources can be added and removed on demand. This
book presents an approach that simplifies the
development of Grid applications and empowers
end-users to take full advantage of Grid
infrastructure. The approach uses domain specific
modeling, a modern software engineering method for
automating the development of software, to develop a
workflow tool that can be used by end-users to create
complex Grid applications graphically. This book
provides an introduction to Grid computing and
workflow systems as well as a practical exercise in
domain specific modeling. As such, this book should
be of great use for software engineers and anyone
else interested in reaping the benefits of Grid
computing and scientific workflows.
