cals” that are each roughly equivalent to a Borgmaster minus
its persistent store and link shards. Omega schedulers use
optimistic concurrency control to manipulate a shared repre-
sentation of desired and observed cell state stored in a cen-
tral persistent store, which is synced to/from the Borglets by
a separate link component. The Omega architecture was de-
signed to support multiple distinct workloads that have their

scheduling policies (e.g., long-running servers, batch jobs
from various frameworks, infrastructure services like clus-
ter storage systems, virtual machines from the Google Cloud
Platform). On the other hand, Borg offers a “one size fits all”
RPC interface, state machine semantics, and scheduler pol-
icy, which have grown in size and complexity over time as a
result of needing to support many disparate workloads, and
scalability has not yet been a problem (</span><span style="font-size:10pt;font-family:CMSY10">§</span><span style="font-size:10pt;font-family:NimbusRomNo9L">3.4).</span></p><p><span style="font-size:10pt;font-family:NimbusRomNo9L"> </span></p>
