Is Omega the successor? The Borg paper mentions Omega : Omega [69] supports multiple parallel, specialized “verti- 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
own application-specific RPC interface, state machines, and 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 (§3.4).
