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.
