QoD-Centric NaaS Strategy: Policy-Orchestrated Multi-Access Service - Daniel Kibler, EIS Visual & Niem Dang, NHD Consulting LLC

Monday May 18, 2026 11:20am - 12:00pm CDT

200F (Level Two)

Delivering predictable, high‑quality network services in dense, multi‑access edge environments remains a central challenge for operators pursuing a Network‑as‑a‑Service (NaaS) strategy, where programmable APIs expose network capabilities as on‑demand services. Quality‑on‑Demand (QoD) APIs act as the intent interface in this model, enabling applications to request session‑level performance characteristics. QoD requires sophisticated new network control‑plane orchestration to address heterogeneous enforcement, multi‑access behavior, and session continuity issues across Wi‑Fi, private 5G, and public 5G domains.

QoD refers specifically to the CAMARA Project’s implementation, which provides standardized APIs for dynamic multi‑access orchestration, session‑level QoS enforcement, and integration with 3GPP control‑plane functions, including PCF, SMF, NEF, and NWDAF together with UE‑side ATSSS for traffic steering, switching, and splitting.

In this session, we will overview the strategic importance of QoD APIs, the global scale of the emerging NaaS domain, and detail Open Source technologies that are foundational to the industry.

Troubleshooting Like a Senior on Day 1: ReAct Agents With Real-Time Cluster Evidence - Bohyun Choi, UCLIX; Woobin Hwang, NEOWIZ Partners; TaeJi Kim, Bungaejangter Inc

Monday May 18, 2026 2:25pm - 3:05pm CDT

200F (Level Two)

If a production incident hits on your first day, can you debug it? Or if you are a senior engineer, do you find it impossible to download your years of debugging intuition into a new hire’s head?
Kubernetes troubleshooting often depends on undocumented decision paths: where to look first, which signals to trust, and how to turn a sea of logs into a testable hypothesis.

In this talk, we introduce KUBE-RCA, an open-source incident assistant that plugs into your preferred external LLM and provides real-time cluster evidence (metrics, logs, events) as structured context. Using a ReAct loop, the agent proposes hypotheses, runs an allowlisted set of read-only commands/queries, ties each claim back to evidence, and publishes a concise RCA draft directly to your team channel.

We’ll share the design decisions behind our guardrailed execution loop and how we encode SRE intuition into prompts and checks. You’ll walk away with an understanding of how to make incident response more systematic. So engineers of any tenure can resolve issues faster, with less senior interruption.

BoF: DRA for AI Workloads: Where Does the Spec Need To Go Next? - Yahav Biran, Amazon

Monday May 18, 2026 3:35pm - 4:20pm CDT

200F (Level Two)

Kubernetes Dynamic Resource Allocation is now being adopted by hardware vendors implementing drivers for accelerators and high-speed networking. But as real-world AI workloads hit the spec—disaggregated inference across multiple nodes, topology-aware co-location of compute and network devices, per-workload hardware configuration—gaps are emerging. This Birds of a Feather session invites platform engineers, infrastructure teams, and Kubernetes contributors to compare notes on where DRA works well and where the spec leaves teams filling in the blanks themselves. We will use the AWS Trainium Neuron DRA driver as a concrete reference point to ground the discussion, then open the floor: What attributes should be standardized across vendors? How should multi-device atomic allocation be handled? What does the community need to build so that DRA delivers on its promise across all accelerator hardware?

Why Is It Always DNS?: Rethinking & Engineering Node-Level DNS Resolution in Kubernetes - Shaheen Sayyed & Ankur Singh, Red Hat

Monday May 18, 2026 4:30pm - 5:10pm CDT

200F (Level Two)

Is it DNS or is it network? & why is answer always DNS? In K8s, most clusters quietly rely on /etc/resolv.conf on every node for all non-service name resolution. At scale, this dependency becomes a liability, reducing caching & observability while causing fragile forwarding, higher latency, upstream resolver overload, and host-level divergence in multi-cloud environments

This talk will explain how K8s actually consumes node DNS today & then present two solutions: CoreDNS for large, complex clusters; dnsmasq for medium scale that bring deterministic caching, controlled forwarding, traffic steering, and real visibility—turning DNS from black box into an engineered system component

Attendees will gain a framework to choose DNS implementation strategies by understanding trade-offs based on cluster scale, workload type and platform maturity. We’ll compare CoreDNS & dnsmasq, surface real failure modes, & show how different designs affect latency, reliability, & blast radius.

Monolithic To Cloud Native: Lessons From Migrating Heroku To EKS at Scale - Mateen Anjum, Phono Technologies Inc

Monday May 18, 2026 5:25pm - 6:05pm CDT

200F (Level Two)

When our platform served a SaaS company growing from
9M$ to $100M ARR, we faced a decision every scaling team encounters: stay on Heroku or migrate to Kubernetes. We chose migration. This talk shares the real lessons from moving 47 microservices to EKS while maintaining 99.9% uptime.

I will cover the migration patterns that worked, the ones that failed spectacularly, and the operational changes that made the difference between success and rollback. You will learn how we reduced API latency from 700ms to 70ms, why our first three migration attempts failed, and what "production ready" actually means when your customers include enterprise clients with strict SLAs.

This is not a vendor pitch or theoretical framework. It is a practitioner's account of what happens when you bet your platform on Kubernetes and have to deliver.

Attendees will leave with a realistic migration checklist, common failure patterns to avoid, and honest metrics on what to expect during and after migration.

From Guidance To Guardrails: Cost & Carbon Policy-as-Code With OPA in CI - Machiko Shinozuka & Kouki Hama, NTT, Inc

Tuesday May 19, 2026 11:00am - 11:40am CDT

200F (Level Two)

Several guidelines such as FinOps Framework and Green Software Patterns provide principles for cloud optimization, but they include both abstract ideas and practical details with multiple concerns like cost and sustainability. This makes human reviews inconsistent. In this talk, we show how such guidance can be evaluated consistently in CI using Open Policy Agent (OPA).

We present a two-layer policy design: evaluation logic stays small and readable in Rego, while policy rules such as thresholds and exceptions are defined in structured JSON. This separation makes policies easier to maintain by contributors without Rego expertise. CI checks consume an input schema derived from configuration or IaC artifacts and return review-ready decisions—allow, warn, or block—along with a rule identifier, rationale, and a suggested follow-up.

What you will learn:
・How to extract checkable criteria from abstract guidance
・How to design a stable input schema
・How to structure a rules catalog so that policy evaluation remains possible even when multiple concerns interact
・How to run a policy change process that does not depend on a small set of Rego experts

Unified Database Provisioning and Management on Kubernetes - Kyle Avants, Percona

Tuesday May 19, 2026 11:55am - 12:35pm CDT

200F (Level Two)

Running production-grade databases on Kubernetes is becoming increasingly common, but managing their lifecycle remains fragmented and complex for SRE and DevOps teams. Critical operations—scaling, RBAC, monitoring, backup, and restore—currently require navigating distinct, database-specific APIs and tools. This complexity prevents teams from fully realizing the operational efficiency and uniformity that Kubernetes provides.

This talk introduces OpenEverest, the open-source platform designed to address this operational gap. OpenEverest provides a single, unified UI and CLI to manage SRE functions for popular open-source databases such as PostgreSQL and MySQL deployed on Kubernetes. It abstracts away database-specific differences, offering standardized control for scaling, integrated observability, granular RBAC, and reliable data protection.

Join us to learn how OpenEverest simplifies the path to production readiness, reduces operational toil, and is building a pioneering open-source database management layer.

Off-Grid Cloud Native: Building Trustworthy Sponsor-to-School Delivery With Kubernetes - Vuyo Mhlotshane, Loakit

Tuesday May 19, 2026 2:10pm - 2:50pm CDT

200F (Level Two)

In many rural communities, the hardest part of funding education is not raising money. It is knowing with confidence that resources reached the right school and were used as intended.

In this session, I share a real-world, open-source reference architecture for a pay-on-proof delivery pipeline where sponsor funds are released only after delivery can be verified. The system is designed for low-bandwidth and intermittent connectivity environments and uses Kubernetes, event-driven workflows, cryptographic proofs, and auditable logs to close trust gaps between sponsors, vendors, and schools.

We will walk through key design decisions, how to think about offline-first systems, and where trust commonly breaks in real deployments, along with practical ways to address those gaps without heavy infrastructure.

Attendees will learn:

- How to model sponsor to vendor workflows using events and state
- Patterns for building offline-friendly, cloud native systems
- Practical digital trust controls including identity, auditability, and proof of delivery

This talk is for platform engineers, SREs, and open source practitioners building systems that must work in real-world conditions.

Lightning Talk: Reliability at the Edge: Fail-Safe Multi Cluster Orchestration With Kubestellar - Munachimso (Muna) Nwaiwu, Cornell University

Tuesday May 19, 2026 3:05pm - 3:15pm CDT

200F (Level Two)

Managing a single Kubernetes cluster is a solved problem. However, extending Kubernetes to the edge introduces a fundamental systems crisis. In remote environments, network partitions are guaranteed. When orchestrators demand real-time synchronization, routine network drops lead to configuration drift and control-plane breakdown.

This session analyzes how KubeStellar (a CNCF Sandbox project) attempts to solve this reliability crisis. Evaluated from a systems and network perspective, we dissect how KubeStellar abandons synchronous replication for an asynchronous, hub-and-spoke model. By decoupling its Workload Description Space (WDS) from the transport layer, it leverages eventual consistency to treat disconnected edge nodes as expected, not a fatal error.

To ground this theory in reality, we explore our ongoing research at Cornell University’s Smart Farms. In remote agriculture, long-term partitions are daily realities. We will outline our progress using KubeStellar to manage geographically dispersed clusters, presenting an architectural roadmap for how eventual consistency can ensure local workloads survive extended disconnects and deterministically reconcile upon reconnection.

Lightning Talk: Taking a U-Turn for Caches: Moving Back From Remote To Local - Aditya Mohan, Amazon

Tuesday May 19, 2026 3:25pm - 3:35pm CDT

200F (Level Two)

With the growth of CPU compute and larger memory heaps, many cloud-native workloads that traditionally relied on remote caches like Redis and Memcached can now benefit from in-process caching using open source libraries.

In this session, we focus on Java-based cloud-native services and show how local caches, such as Caffeine, can colocate cache with application logic, reducing network overhead, simplifying consistency management, and improving latency. Drawing on large-scale production experience, we’ll explore cache invalidation, freshness guarantees, near-cache patterns, and scalability trade-offs, along with practical lessons for handling staleness, TTLs, and other caching challenges while reducing operational complexity and cost.

Finally, we’ll discuss how emerging open source tools like Databricks’ Dicer apply these caching and orchestration principles at scale for real-time services, representing the next frontier. Attendees will learn methods to design low-latency, high-throughput, maintainable, and cost-efficient caching solutions for cloud-native architectures using open source tools.
