Ziv Yatzik manages 600+ Postgres clusters in a closed network environment with no public cloud. After existing backup solutions proved unreliable — causing downtime when disks filled up — his team built a new architecture using pgBackRest, Argo CD, and Kubernetes CronJobs.

You will learn:

- Why storing WAL files on shared NAS storage prevents backup failures from cascading into database outages
- How GitOps with Argo CD lets them manage backups for hundreds of clusters by adding a single YAML file

Nicholaos Mouzourakis, Staff Product Security Engineer at Gusto, explains how Open Policy Agent (OPA) integrates with Kubernetes for authorization. He highlights OPA's versatility and performance characteristics, noting that a single node can handle numerous requests with proper optimization.

He describes multiple deployment options, including:

- Standing up multiple OPA instances
- Setting up auto-scaling groups
- Co-locating OPA with server pods
- Running OPA as a WASM module for lower latency

"Self-service capabilities without governance is how you get outages at 3 AM."

Zain Malik from ExoStellar tackles the tension between developer empowerment and platform governance. A mature platform provides standardized interfaces that give users access to what they need—kernel layers, node layers, DOS systems—without compromising reliability.

The key insight: centralization isn't about restriction, it's about creating reliable building blocks that scale.

Ritesh Patel, Co-founder @ Nirmata, explains how Nirmata's AI platform engineering assistant differentiates itself in the market through strategic focus rather than broad appeal.

He demonstrates a direct approach to competitive positioning by acknowledging that their solution isn't for everyone - it's specifically designed for teams that have already adopted Kyverno as their policy engine.

Tibo on why Kubernetes isn't just for enterprise scale — it can be a practical choice for solo self-hosters too.

You will learn:

- Why Ansible's declarative promise fell short with the Podman collection, forcing sequential imperative steps instead of desired-state definitions
- How community Helm charts replace the need to write and maintain every manifest yourself
- Why GitOps isn't just a deployment workflow — it's a disaster recovery strategy when your infrastructure lives in your living room

Self-service and governance aren't competing forces — they work together.

Peter Kelly explains how Tigera's tiered network policies in Project Calico let platform teams lock down critical rules at an upper layer while giving developers a lower tier to manage their own policies. Security stays immutable at the top, and developers get autonomy within those guardrails.

The key: treat policy tiers like layers — compulsory at the top, flexible at the bottom.

This interview is a reaction to Ben Poland's episode https://ku.bz/klBmzMY5-

Jan Ludvik on how he cut EKS node startup from 65 to 45 seconds and reduced P90 pod startup by 30 seconds across ~1,000 nodes.

You will learn:

- Why Kubelet's serial image pull default quietly blocks pod startup, and how parallel pulls fix it
- How EBS lazy loading can silently negate image caching in AMIs — and the critical path workaround
- A Lambda-based automation that temporarily boosts EBS throughput during startup, then reverts to save cost
- The kubelet metrics and logs that expose pod and node startup latency, most teams never monitor
