Google Borg diventa Omega

Ecco un'altro pezzo importante dell'infrastruttura di Google. Google Borg che diventa Omega.

Pubblicato un paper dopo aver rilasciato il tutto OpenSource. Avevamo già discusso elementi infrastrutturali qui: "Come Google usa le tecnologie Percolator, Dremel e Pregel?"

Large-scale cluster management at Google with Borg

Abstract:
Google's Borg system is a cluster manager that runs hundreds of thousands of jobs, from many thousands of different applications, across a number of clusters each with up to tens of thousands of machines. It achieves high utilization by combining admission control, efficient task-packing, over-commitment, and machine sharing with process-level performance isolation. It supports high-availability applications with runtime features that minimize fault-recovery time, and scheduling policies that reduce the probability of correlated failures. Borg simplifies life for its users by offering a declarative job specification language, name service integration, real-time job monitoring, and tools to analyze and simulate system behavior.
We present a summary of the Borg system architecture and features, important design decisions, a quantitative analysis of some of its policy decisions, and a qualitative examination of lessons learned from a decade of operational experience with it.
