Abstract. The ability to deploy Grid infrastructure and services across organizational boundaries (rapidly, reliably, and scalably) is critical for the success of large-scale service based grids such as OGSA. We report the results of the UKOGSA Evaluation Project infrastructure and services deployment experiments, and analytically compare application versus service deployment. The use of a 3rd party component deployment technology to remotely automate installation and service deployment is discussed, and outstanding problems and potential solutions and benefits are presented. We conclude that grid deployment must be treated as a first-order activity by integrating secure deployment capabilities into the middleware, to enable deployment of secured infrastructure and services across organizations.
