5. VSHN - The DevOps Company
● Jan Šafránek, Red Hat & David Zhu, Google
● What is a PersistentVolume? What is a PersistentVolumeClaim? Why are
there two separate objects instead of just one? How is storage presented
into my containers?

Kubernetes Storage 101

6. VSHN - The DevOps Company
● Josh Berkus, Red Hat
● benchmarking various forms of Kubernetes storage, including host storage,
network storage, cloud storage and cloud-native storage systems like Rook.
Let us share with you the results of running PostgreSQL, CockroachDB and
filesystem benchmarks
● “Show me the data!”

Benchmarking Cloud Native Storage

7. VSHN - The DevOps Company
● Michelle Au, Google
● run stateful applications across multiple failure domains for increased
availability, and demonstrate how Kubernetes automatically recovers from
failure scenarios at the node and zone layers
● takeaway: use the correct type of storage for the job (accessibility vs
availability vs durability vs access mode)

Improving Availability for Stateful Applications
in Kubernetes

8. VSHN - The DevOps Company
● Saad Ali, Senior Software Engineer, Google
● Separating: consuming block and file storage from a pod running in
Kubernetes, deploying a stateful app (like a database) on Kubernetes using
storage and workload primitives and deploying a software defined storage
system on top of Kubernetes to provide block or file storage.
● takeaway: use the correct type of storage for the job (object vs SQL vs time
series vs NoSQL vs message queue vs file vs block)

Storage is Hard

9. VSHN - The DevOps Company
● John Studarus, Packet Host
● Discussion on deploying and running Kubernetes clusters across micro
datacenters supporting edge applications.
● Interesting use case

10. VSHN - The DevOps Company
● Ahmet Alp Balkan, Google & Maciej Szulik, Red Hat
● Many users install extra tools for tasks they can't do with kubectl. Did you
know you can write and distribute your own kubectl subcommands?
● Takeaway: Make repetitive/complex tasks on Kubernetes simpler by sharing
