Descripción del proyecto
Superar los retos del desarrollo de infraestructuras informáticas descentralizadas
Las infraestructuras informáticas descentralizadas (IID) son fundamentales para muchas actividades, empresas e industrias de todo el mundo. Sin embargo, se enfrentan al reto de desarrollar e implantar con eficacia aplicaciones distribuidas en toda su explotación sin problemas de seguridad o funcionamiento. El equipo del proyecto DOS, financiado con fondos europeos, pretende desarrollar «hardware» y «software» novedosos que ofrezcan a los programadores una opción mucho más eficaz y rentable para introducir cambios en las IID. Estas tecnologías constituirán un sistema operativo descentralizado basado en micronúcleos para ofrecer una gestión unificada de las IID y una novedosa solución de «hardware» conectable que ayude a superar la heterogeneidad del «hardware» y a gestionar de forma más eficiente herramientas y procesos. La labor del proyecto DOS promete revolucionar las IID y aumentar su eficacia.
Objetivo
The DOS project targets the challenge of developing and deploying distributed applications on large-scale decentralized computing infrastructures (DCIs) such that their dependability properties, e.g. safety and security, can be enforced by the foundational layers of the system stack in a policy-compliant manner.
While it is possible today to construct distributed applications, it is challenging to ensure that their dependability properties are preserved end-to-end in a DCI consisting of a diversified set of compute nodes hosted in multiple administrative jurisdictions. This situation is primarily caused by the limitations of existing system stack foundations: (a) hardware: DCIs expose heterogeneous compute nodes that lack a unified interface to access, isolate, and manage them; (b) OS: current OSes lack mechanisms for resource management in a safe and secure manner for heterogeneous nodes operating across multiple trust domains. As a result, programmers rely on ad-hoc programming and deployment mechanisms, which are not only prohibitively expensive to develop and error-prone but also cannot ensure compliance with the dependability requirements.
The DOS project seeks to bridge this gap by pursuing a radically new hardware/OS co-design by introducing
1. a pluggable hardware component called Isolation Control Unit (ICU) that abstracts out the hardware heterogeneity while providing a minimalistic interface for resource management, isolation, communication, and trust establishment.
2. a microkernel-based Decentralized Operating System (DOS) that builds on ICUs to manage DCIs as a unified dependable system substrate to enable policy-compliant application deployment.
Overall, our work aims to empower programmers by providing a generic distributed programming framework on top of DOS to concisely specify the dependability policies along with the application logic, while our system stack transparently enforces these policies in decentralized environments.
