Software AG and the Potsdam-based Hasso Plattner Institute for Software
Systems Engineering (HPI) today announced the successful completion of a
one-year research project examining the impact of service-oriented
architecture (SOA) governance on Green IT practices.

Working together, the two organizations developed methods and tools for
optimizing resource sharing of IT services, thereby reducing energy
consumption and lowering hardware costs.
Heavy energy consumption and the associated economic and environmental
impact that it creates has become one of the greatest challenges facing
large datacenters.
To counter this, the Operating Systems and Middleware team at the Hasso
Plattner Institute and Software AG have conducted an "SOA Eco Runtime
Governance" study.  Using CentraSite, the top-ranked solution for SOA
governance and service lifecycle management, the partners created a series
of new policies that can be deployed in a service-oriented architecture.
Using these policies, administrators of complex IT landscapes can determine
exactly how much computing power they need as well as the maximum amount of
energy each service may use, which helps them regulate and more tightly
control energy costs.  For example, policies within CentraSite were used to
allocate resources between multiple services with these policies being
modified as needed at runtime.
"Through SOA runtime governance, we can give IT departments more options for
distributing their available computing power more efficiently.  In this
context, CentraSite serves as the central hub with HPI's technology acting
as a sentinel for the system resources.  This means that users can reduce
maintenance and energy costs for their hardware by consolidating resources,"
states Guido Laures, director of product management for SOA Governance at
Software AG.
Prof. Andreas Polze, manager of HPI's Operating Systems and Middleware
group, explains: "The eco-computing project is just one of our research
projects in the field of operating systems. Our general focus is on new
paradigms, architecture models, interfaces, and implementation technologies
for supporting service-based systems. Besides resource management, our
research addresses questions regarding implementation planning and charging
of services."
