Brock Mowry, CTO @ Tintri, addresses the persistent debate about whether Kubernetes is ready for stateful workloads.

He argues that concerns about Kubernetes handling stateful applications are outdated, pointing to the maturation of key technologies, such as persistent volumes and CSI (Container Storage Interface)

Brock explains how the ecosystem has evolved beyond basic storage attachment to include comprehensive data management services such as data protection with replication and quality of service capabilities.

Ratan Tipirneni, President & CEO @ Tigera, discusses the competitive landscape for Kubernetes networking solutions and explains how organizations can avoid vendor lock-in.

He outlines three main alternatives teams consider:

1. Calico open source (the most widely deployed solution)
2. DIY approaches, and
3. Native Kubernetes platform functionality.

Ratan emphasizes how platform-specific solutions create vendor lock-in risks and explains how Calico's platform-agnostic approach gives organizations pricing leverage and negotiating power with platform vendors.

Most developers assume Kubernetes requires an enterprise budget. Varnit Goyal proves otherwise — he built a full three-node Kubernetes cluster for $2.16/month using Rackspace Spot Instances.

You will learn:

- How Spot Instance bidding works and which strategies keep costs and preemption low
- Using Tailscale Kubernetes operator as a free alternative to traditional load balancers
- Running real development dependencies (Kafka, Elasticsearch, Postgres) on a budget cluster

nix-csi mounts Nix store paths into Kubernetes pods using CSI ephemeral volumes that share pod lifetimes.

It supports pulling pre-built store paths, evaluating flake references, or building Nix expressions directly within pod specifications.
