Keynote: Engineering Without Limits: A Decade of Kubernetes Powering PlayStation’s Evolution - Chris McEniry & Swathi Somanchi, Sony

Tuesday June 17, 2025 09:56 - 10:01 JST

Level 1 | Pegasus A-B1

8 year ago, we started to release Playstation products powered on top of Kubernetes. At the time, it was focused on accelerating our time to market. Little did we know that it would also provide the rallying flag for bringing together multiple parts of the organization to work in a consistent manner. With common features available to all application teams, they could focus on improving the game and game developer experience, instead of re-inventing toiling wheels.

As we look to the future, we're once again able to use the Kubernetes ecosystem as a rallying point. It's enabling us to expand our availability and capabilities into new hosting environments. We're moving up the value chain by replacing once novel but now bespoke components with modern and now commodity logic.

In this talk, we'll summarize our experience bringing a common platform to Sony Interactive Entertainment, what the future holds, and how the past, present and future help Playstation to continue to provide a gaming world where Play has no Limit.

Cloud Native Scalability for Internal Developer Platforms - Hiroshi Hayakawa, LY Corporation

Tuesday June 17, 2025 12:10 - 12:40 JST

Level 1 | Orion

Platform Engineering enables developers to focus on business value-aligned tasks by providing internal developer platforms (IDPs) that automate non-essential tasks. Kubernetes is widely used as a foundation for IDPs thanks to its scalability and flexibility.

However, Kubernetes was designed as a general workload orchestrator, not a platform component. As a result, IDP builders must integrate additional Cloud Native technologies and customizations, which can create scalability bottlenecks. At LY Corporation, his team has developed a Kubernetes-based, multi-tenant IDP running over 140K pods, and they faced such scalability challenges.

In this session, he will discuss scalability bottlenecks faced in the IDP, including observability pipelines, access control, etc. He will also explore scaling strategies for IDPs and how they address real-world scalability issues. By the end of this session, you will gain deeper insights into scalability challenges from a platform builder’s perspective.

Navigating Millions of Kafka Events in Real Time With OTel - Siddharth Vijay, Baazi Games

Tuesday June 17, 2025 14:10 - 14:40 JST

Level 1 | Orion

How can real-time event streaming platforms, handling millions of events and complex data processing, maintain peak performance and reliability? Managing the same has previously been complex. The latest agent changes and addition of semantic convention in OpenTelemetry make it ideal to monitor highly distributed event streaming architectures (EDA) like Kafka. In this session we will discuss how these changes help standardize telemetry, explain the usage of span links for capturing several traces for a transaction in EDA.

The talk will also cover how Otel enables automatic anomaly detection particularly useful for identifying issues like Consumer Lag, Increased Latency in Event Processing, and Partition Failures. By leveraging context propagation, Otel tracks end-to-end latency across the entire Kafka ecosystem, including producers, brokers, and consumers.

Debugging OpenTelemetry: Ensuring Your Observability Signals Are Spot On - Kasper Borg Nissen, Dash0

Tuesday June 17, 2025 14:50 - 15:20 JST

Level 1 | Orion

OpenTelemetry has become the go-to framework for unifying observability signals across metrics, logs, and traces. However, implementing OpenTelemetry often comes with its own set of challenges: broken instrumentation, missing signals, and misaligned semantic conventions that undermine its effectiveness. Debugging these issues can be daunting, leaving teams stuck with incomplete or unreliable observability data.

In this session, Kasper will demystify the debugging process for OpenTelemetry. Attendees will learn how to identify and troubleshoot common issues, ensure signals are transferred correctly, and align instrumentation with semantic conventions for consistent insights. Through live demos, Kasper will showcase techniques for validating resource configurations, debugging signal pipelines, and building confidence in your observability setup. This session is designed for anyone looking to unlock the full potential of OpenTelemetry and create robust observability practices.

Mastering Authorization: Integrating Authentication and Authorization Data in Cloud Native Apps - Yoshiyuki Tabata, Hitachi, Ltd.

Tuesday June 17, 2025 14:50 - 15:20 JST

Level 1 | Pegasus B2-C

Authorization is one of the most important considerations for cloud-native applications, as highlighted by the OWASP Top 10. For a long time, there was no clear standard, making authorization a significant challenge for many implementers. The OpenID Foundation AuthZEN WG is now working on standards, focusing on interfaces between PEP (Policy Enforcement Point) and PDP (Policy Decision Point), which provides some hope.
However, managing authorization data remains challenging. Since this data is closely related to authentication data, architects often struggle with how the OP (OpenID Provider) and PDP should manage and integrate it. There are multiple methods, and the best approach varies by use case.
In this session, Yoshiyuki Tabata will explain various methods for managing and integrating authentication and authorization data. He will also describe implementation using Keycloak for OP and Topaz for PDP, providing valuable insights into effective data management.

The Future of Prometheus Exposition Format - Arthur Sens, Grafana Labs

Tuesday June 17, 2025 15:50 - 16:20 JST

Level 1 | Pegasus A-B1

OpenMetrics (OM) had a wild journey: it started as a project to standardize the Prometheus exposition format, and it became an entirely separate CNCF Incubating project. Even though the project had high maturity, it struggled for years to find tools to comply with the first version of the spec. Finally, in 2025, it was incorporated back into the Prometheus Github organization so Prometheus developers could lead the efforts for OM 2.0.

In this talk, Arthur, a Prometheus maintainer and OpenMetrics contributor, will walk you through the main challenges that tools like Prometheus and OpenTelemetry face when trying to comply with OpenMetrics 1.0 and how the community plans to address these challenges in OM 2.0.

The audience will also learn how changing an exposition format can make Prometheus and OpenTelemetry-Collector more memory-efficient while making their specifications easier to translate into each other!

Practical Cloud Native Compliance Automation With OSCAL Compass - Chris Butler, Red Hat & Takumi Yanagawa, IBM Research

Tuesday June 17, 2025 15:50 - 16:20 JST

Level 1 | Pegasus B2-C

Cloud presents many advantages to users in terms of flexibility, scalability and innovation. Unfortunately compliance has become more complex as standards and regulations are used by end consumers as a proxy for security of underlying platforms whose operations are opaque. Consequently platform providers have ever increasing compliance obligations.

Compliance-as-code encompasses many activities such as automation of system configuration and general DevSecOps approaches. One perpetual challenge is how to provide machine readable workflows which span from standard to audit to allow automation in a way that scales.

OSCAL-Compass, a CNCF sandbox project, provides tooling to manage both the compliance artefacts as code and link those artefacts to executable policies. This talk will provide practical introduction to using OSCAL compass to document and enforce compliance controls using two of its tools: Compliance Trestle and C2P (compliance2policy) in the context of Kubernetes clusters.

Inspired by Sailor Moon and Dragon Ball GT, this talk breaks down how eBPF enhances observability, networking, and security, using the Sailor Guardians and Gohan to make eBPF approachable. We’ll break down topics like real-time observability by comparing it to psychic flames.
And just as unchecked power in anime can lead to chaos, eBPF’s immense capabilities need to be used wisely. Drawing from Dragon Ball GT's arc where the Dragon Balls become a threat, we’ll examine best practices for safe deployment of eBPF (e.g., LSM, verifier constraints, Linux Capability restrictions). Spoiler alert: our Sailor Guardians and Gohan will come out victorious, worry not!

By the end, you’ll gain a clear understanding of how to wield eBPF safely and effectively in cloud native environments, no Super Saiyan transformation required!

Dynamic Provisioning and Capacity-Aware Scheduling for Local Storage - Yuma Ogami, Cybozu, Inc.

Tuesday June 17, 2025 16:30 - 17:00 JST

Level 1 | Orion

In this session, the speaker presents TopoLVM, a CSI plugin for local storage, and introduces an upcoming Kubernetes feature for local storage that he and his team are working on.

Local storage is promising for applications that require high I/O performance, like Elasticsearch and MySQL. TopoLVM provides many features like raw block volumes, resizing, and dynamic provisioning to manage local storage in Kubernetes easily. It also includes a capacity-aware pod scheduling feature that considers each node's local storage capacity.

Currently, this capacity-aware feature is achieved by a scheduler extender, which has two main issues:

1. Many admins don't have the right to install scheduler extenders.
2. The scheduler extender is TopoLVM specific.

To address these issues, he will introduce a KEP titled "KEP-4049: Storage Capacity Scoring of Nodes for Dynamic Provisioning." to be able to TopoLVM's scheduling logic for all CSI drivers without using scheduler extenders.

Your SBOM Is Lying To You – Let’s Make It Honest - Justin Cappos & Yuchen Zhang, New York University

Tuesday June 17, 2025 16:30 - 17:00 JST

Level 1 | Pegasus B2-C

SBOMs (Software Bills of Material) are essential for improving visibility and security in the software supply chain. As open-source code drives modern development, organizations face growing security risks due to limited transparency in software dependencies. Attacks like SolarWinds (2020) and Kaseya (2021) highlight the urgent need for stronger software supply chain security.
However, SBOMs are often inaccurate. This talk explores why these inaccuracies occur, how attackers exploit them, and how to address these issues. A key challenge is dependency management file analysis (e.g., cargo.toml for Rust), which struggles to track components effectively.
Enter SBOMit, an OpenSSF sandbox project leveraging in-toto attestations to create cryptographically verifiable SBOMs. By capturing supply chain steps as they occur, SBOMit enhances accuracy, mitigates tampering risks, and strengthens security. This talk examines SBOMit’s role in improving SBOM reliability across the CNCF ecosystem.
