Migration in the Stencil Pluralist Cloud Architecture
Tai Liu, Zain Tariq, Barath Raghavan, Jay Chen

TL;DR
This paper proposes Stencil, a pluralist cloud architecture that facilitates migration between competing services, addressing challenges in linked data migration, and enabling scalable, trustable decentralized web services.
Contribution
It introduces a unifying abstraction for pluralist cloud architecture that supports seamless data migration and incremental deployment of decentralized services.
Findings
Stencil enables correct data migration between services.
It supports deployment of new decentralized services.
Addresses linked data migration challenges.
Abstract
A debate in the research community has buzzed in the background for years: should large-scale Internet services be centralized or decentralized? Now-common centralized cloud and web services have downsides -- user lock-in and loss of privacy and data control -- that are increasingly apparent. However, their decentralized counterparts have struggled to gain adoption, suffer from their own problems of scalability and trust, and eventually may result in the exact same lock-in they intended to prevent. In this paper, we explore the design of a pluralist cloud architecture, Stencil, one that can serve as a narrow waist for user-facing services such as social media. We aim to enable pluralism via a unifying set of abstractions that support migration from one service to a competing service. We find that migrating linked data introduces many challenges in both source and destination services as…
