Descrizione del progetto
Superare le sfide dello sviluppo di infrastrutture informatiche decentralizzate
Le infrastrutture informatiche decentralizzate sono fondamentali per molte operazioni, aziende e industrie in tutto il mondo. Devono però affrontare la sfida di sviluppare e implementare in modo efficiente applicazioni distribuite in tutte le loro operazioni, senza problemi di sicurezza o di funzionamento. Il progetto DOS, finanziato dall’UE, si propone di sviluppare un hardware e un software innovativi che offrano ai programmatori un’opzione molto più efficiente ed economica per implementare le modifiche in tali infrastrutture. Le tecnologie in questione consisteranno in un sistema operativo decentralizzato basato su microkernel, per offrire una gestione unificata delle infrastrutture informatiche centralizzate, e in una nuova soluzione hardware collegabile che consente di superare l’eterogeneità dell’hardware e di gestire in modo più efficiente gli strumenti e i processi. Il progetto DOS promette di rivoluzionare le infrastrutture informatiche decentralizzate e di migliorarne l’efficacia.
Obiettivo
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.
