DNS-embedded service endpoint registry for distributed e-Infrastructures

Abstract Distributed e-Infrastructure is a key component of modern BIG Science. Service discovery in e-Science environments, such as Worldwide LHC Computing Grid (WLCG), crucial functionality that relies on service registry. In this paper we re-formulate the requirements for endpoint registry based our more than 10 years experience with many systems designed or used within WLCG e-Infrastructure. To satisfy those proposes novel idea to use existing well-established Domain Name System (DNS) infrastructure together suitable data model The presented ARC Hierarchical Endpoints Registry (ARCHERY) system consists minimalistic representing services and their endpoints e-Infrastructures, rendering embedded into DNS-records, lightweight software layer DNS-record management client-side discovery. Our approach ARCHERY required minimal development inherits all benefits one most reliable distributed information source internet, DNS infrastructure. particular, deployment, operation fully relying DNS. Results deployment use-cases are provided performance analysis.
