+By a volcano maintainer from Huawei - a very wholesome guy.
+I don't know why the organizers always tend to schedule these very technical topic by people with a bit of an harder accent (totally understandable but very quiet) near the end of the conference or day? I thank the Sakura Edition Red Bull for keeping my attention span up and running for the last two sessions of the day.

+## History of vokcano
+
+- 2017: Kube-Batch open soruce
+- 2019: Volcano Open Source
+- 2020: CNCF Sandbox
+- 2022: CNCF Incubation
+- 2026: Road to graduation
+
+## Volcano feature overview
+
+- Unified Scheduler
+- Queue Management
+- Workload Colocation
+- Multi cluster scheduling
+- Heterogenus Device Support
+- Multiple Scheduling policies
+
+## Why topology awareness?
+
+- Scenario 1: Bottlenecks in LLM-Training when jobns are not placed on GPUs that are close
+- Scenario 2: Inference runs as Seperate Prefill and Decode Jobs on different hardware -> Short network hops needed
+- Node labels can be used but are very limited
+- Datacenter network architectures are heterogenus -> Everyone can buil in their own style
+
+## Scheduler notation mechansis
+
+- Label: Kueue, Koordinator, KAI Scheduler
+  - Vendor-Specific Syntax
+  - No hierarchy
+  - Need to be manually set
+  - No healthchecks
+  - Cloud Specific
+- CRD (Long term): Volcano
+  - Standardized API (HyperNBode)
+  - Hierarchical (Trees/Zones)
+  - Auto-discovery - Plugin-Ready (e.G. NVIDIA)
+  - Healhchecks
+  - Unified across clouds and on-prem
+
+## Architecture CRD Sample
+
+TODO: Steal Leaf sample from slides
+
+
+## What's next
+
+- GPU 3D Architectures (Internal interconnects, NUMA, external interconnects)
+- DRA integration/collabaration
+- Promotion of HyperNode to a first-class citizen -> Extraction from Volcano to be truly generic
