Description
Configuration is an essential part of the deployment process of any software product.
In the case of Grid middleware the variety and complexity of grid services coupled
with multiple deployment scenarios make the provision of a coherent configuration
both more important and more difficult. The configuration system must provide a
simple interface which strikes a balance between the requirements of small university
laboratories and those of large computing centers. It should also be simple to
maintain alongside rapid developments in the software it is
intended to configure.
This paper describes the evolution of a modular configuration system (YAIM) which is
used to configure different Grid middleware products. It summarizes the lessons
learned during several years of LCG/gLite middleware production use and presents a
new approach chosen to face the
forthcoming challenges. Along with the main design considerations and implementations
decisions, an example of a fully integrated third party grid service (dCache) is also
discussed.
