| Abstract: |
The modern data center is faced with architectural and software engineering
challenges that grow along with the challenges facing observatories: massive
data flow, distributed computing environments, and distributed teams
collaborating on large and small projects. By using VO
standards as key components of the infrastructure, projects can take advantage
of a decade of intellectual investment by the IVOA community. By their nature, these standards are
proven and tested designs that already exist. Adopting VO standards saves
considerable design effort, allows projects to take advantage of open-source
software and test suites to speed development, and enables the use of third
party tools that understand the VO protocols.
The evolving CADC architecture now makes heavy
use of VO standards. We show
examples of how these standards may be used directly, coupled with non-VO
standards, or extended with custom capabilities to solve real problems and
provide value to our users. In the end, we use VO services as major parts of the
core infrastructure to reduce cost rather than as an extra layer with additional
cost and we can deliver more general purpose and robust services to our user
community. |
