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

Molly Sheets, Director of Engineering, Kubernetes at Zynga, discusses the inevitable evolution of Kubernetes operations as organizations mature. She explains how companies typically start with a cluster-per-team approach due to multi-tenancy fears, but eventually hit operational limits that force architectural changes.

Drawing from real examples like Adobe's journey from cluster-as-a-service to internal developer platforms and referencing companies like Mercedes-Benz and Chick-fil-A that once managed hundreds of clusters, Molly illustrates a common pattern: organizations reach a breaking point where they "can't keep hiring people through this problem" and must embrace multi-tenancy.

"Make some building blocks optional, some compulsory—that's your golden path."

Daniel Bryant breaks down platform governance: instead of locking everything down or giving developers full access, create building blocks. Some are required (security policies via OPA, compliance checks), others are optional (CI templates, monitoring configs).

Developers get self-service, and the platform stays safe. The key is treating your platform as a product—listen to your engineers, understand what they need, then build the guardrails into the path itself.

Paul Butler, founder at Jamsocket, explains the three key reasons for choosing Kubernetes in production: managing multiple services across machine pools, implementing infrastructure as code, and leveraging built-in resilience for node failures and deployments.

Despite being the author of "The Hater's Guide to Kubernetes", Paul shares a practical perspective on selecting the right features that work at their company's scale.

Marc Campora examines the complexity burden of Kubernetes decision-making - from cluster topology and instance selection to multi-availability zone deployments.

He explains how the operational overhead creates a dependency on specialists due to Kubernetes' steep learning curve, while the cost structure leads to over-provisioning and underutilized resources. Marc details the bin packing problem where spare capacity remains unused across instances, multiplied across availability zones, resulting in significant bills.
