The presentation discusses the use of Kubernetes (K8s) in research computing, particularly in machine learning operations (mlOps) workflows. The speaker highlights the need for a K8s platform to handle the environmental configuration and workflow integration required by mlOps. The presentation also touches on the challenges of managing different CUDA versions and the need for generous resource provisioning to handle large models in containers.
- Kubernetes is being used in research computing, particularly in mlOps workflows
- A K8s platform is needed to handle the environmental configuration and workflow integration required by mlOps
- Managing different CUDA versions can be challenging

The presentation demonstrates how to create a simple Rook Safe cluster using Kubernetes and explains the two types of Rook Safe clusters: host-based and PVC-based.
- Rook Safe clusters can be created using Kubernetes
- There are two types of Rook Safe clusters: host-based and PVC-based
- Host-based clusters are suitable for simple clusters where all nodes and devices are used for a Rook sequencer
- PVC-based clusters are hardware configuration-free and require only two fields: count and volume claim templates
- PBG-based clusters are easy to expand by increasing the count field
- Advanced configurations include creating OSDs on demand and even OSD splitting among all nodes

Building your own infrastructure can be cost-effective and less complex than using cloud services, with open source technologies like Ceph, Lex, and Oven.
- Cloud services can be expensive and complex, with potential vendor lock-in.
- Building your own infrastructure can be cost-effective and less complex, with open source technologies like Ceph, Lex, and Oven.
- These technologies provide redundant distributed storage, network compute, and frequent releases.
- They can run on cheap hardware, such as Raspberry Pi.
- The speaker has tested these technologies in a data center and found them to be stable and reproducible.

Demo of creating a simple Rook Safe cluster using Kubernetes
- There are two types of Rook Safe clusters: host-based and PVC-based
- PVC-based cluster is easier to expand
- Creating a Rook Safe cluster involves creating an operator, a monitor port, a manager port, and an OSD port
- Expanding the cluster is done by increasing the count field
- Advanced configurations include creating OSDs on demand and even OSD splitting among all nodes

The presentation is about the installation and expansion of Rook, a cloud-native storage orchestrator, using Kubernetes.
- Rook is a cloud-native storage orchestrator that automates storage management in cloud-native environments.
- Rook can be installed in two ways: host-based cluster and PVC-based cluster.
- PVC-based cluster is suitable for simple clusters and is easy to expand by increasing the count field.
- Advanced configurations of PVC-based cluster include creating OSDs on demand and even OSD splitting among all nodes.
- The presentation includes a demo of creating a simple Rook PVC-based cluster with one node and expanding it to two OSDs.

The presentation discusses the use of Multus in Rook-Ceph to better utilize host network interfaces for Ceph Public and Cluster Networks, and the benefits of having dedicated networks for storage.
- Kubernetes presents challenges for storage due to reliance on external storage and lack of portability
- Rook-Ceph is an open source storage operator for Kubernetes that provides persistent storage from within the cluster
- Ceph is a distributed storage software solution that is scalable and provides multiple storage interfaces
- Multus allows for the use of multiple network interfaces on pods, and IP address management for a smoother deployment experience
- Dedicated networks for storage boost performance
- The presentation includes a demo of a running cluster utilizing Multus networks and a comparison of performance with and without Multus
