DBOS

A Database-oriented Operating System


The goal of DBOS–the DBMS-oriented Operating System–is to build a completely new operating system (OS) stack for distributed systems. Currently, distributed systems are built on many instances of a single-node OS like Linux with entirely separate cluster schedulers, distributed file systems, and network managers. We argue that we should instead use a distributed transactional DBMS as the basis for a scalable cluster OS. We have shown that such a database OS can do scheduling, file management, and inter-process communication with competitive performance to existing systems. It can additionally provide significantly better analytics and dramatically reduce code complexity by building core OS services from standard database queries, while implementing low-latency transactions and high availability only once. We are currently working on building a complete end-to-end prototype of DBOS.

The DBOS project includes members from MIT, Stanford, CMU, UW-Madison, Google, VMware, and BCG.
