From Chaos to Control: Evangelising Enterprise Model Registry with KitOps & ModelPack
As organizations adopt Large Language Models (LLMs) and AI-driven workflows, managing model versions, lineage, and governance across hybrid and multi-cloud environments becomes complex. Existing model registries are often vendor-tied or lack interoperability with cloud-native CI/CD and GitOps systems.
In this session, we introduce ModelPack, a core component of the CNCF-incubated KitOps project, that standardizes model packaging, metadata, and promotion workflows — enabling a vendor-neutral enterprise model registry.
We’ll demonstrate how KitOps brings GitOps-style principles to MLOps — from version-controlled model promotion to secure artifact delivery — seamlessly integrating with Kubernetes, OCI registries, and open metadata standards.
Attendees will learn how to design reproducible, auditable, and compliant AI pipelines using open, declarative ModelOps practices.
Breaking the Kernel Bottleneck: High-Performance Networking with Azure CNI & eBPF
Standard Linux networking was never designed for the churn and density of modern container workloads. When production clusters hit the limits of IPTables, latency spikes and CPU consumption can bring services to their knees.
This talk explores the next generation of AKS networking: Azure CNI Overlay with Cilium. We will walk through the architectural differences between VNET-integrated and Overlay networking, specifically focusing on how eBPF bypasses traditional bottlenecks. By the end of this session, attendees will have a clear understanding of performance benchmarking metrics at scale, the technical trade-offs of overlay networking, and a roadmap for migrating production workloads to a more performant, eBPF-driven future.
Freeze,Investigate,Recover: Unlocking Forensic Container Checkpointing with CRI-U
Resilience in Kubernetes often relies on pod restarts, but what if we could checkpoint running containers for forensic analysis and seamless recovery? This is where Checkpoint/Restore in Userspace (CRIU) and its integration with CRI-O and Containerd come into play.
When applications fail, are compromised, or need migration, traditional recovery methods lose valuable runtime data, making debugging, forensic investigation, and live migration difficult. CRI-U enables container-level checkpointing, allowing us to snapshot an application’s complete state, including memory, processes, and open files. This unlocks new security forensics, failure recovery, and workload resilience possibilities.
This session will explore how forensic container checkpointing enhances Kubernetes resilience. Attendees will learn how to securely capture, analyse, and restore container states, ensuring minimal downtime and improved security
Mitigating Supply Chain Risks in Backstage: An Operator's Perspective
Backstage created back at Spotify and later open source has been a reliable solution for developing internal developer platforms (IDP). It unifies an organization’s tooling, services, apps, data and docs into a single, consistent UI allowing developers to easily manage software dependencies.
The Backstage Developer portal, designed to streamline development workflows and enhance collaboration, is not immune to the challenges posed by potential vulnerabilities within its supply chain, that exploits trusted dependencies, libraries and tools introduced through third-party integrations. Understanding and mitigating these risks is crucial for the overall resilience of the development environment.
The talk emphasizes to mitigate supply chain risks within the Backstage Developer portal, focusing on the crucial role of its components from an operator's standpoint. The presentation dissects challenges faced by operators and strategic measures to fortify the development ecosystem
Zero Trust, Full Control: GKE Security in Action
In today's cloud-native landscape, Kubernetes has become the backbone of modern application deployments—but with great power comes great responsibility. As more organizations migrate to Google Kubernetes Engine (GKE), ensuring a strong security posture becomes non-negotiable. From misconfigured workloads to supply chain vulnerabilities, container environments are an attractive target for attackers.
This talk dives into why Kubernetes security is crucial and how Google Cloud's ecosystem provides robust tools to help secure your containerised workloads end-to-end. We'll walk through actionable best practices, demo powerful GKE-native security features, and provide a blueprint for building secure-by-default Kubernetes environments. Whether you're a developer, platform engineer, or cloud architect, you'll leave with practical strategies to level up your container security game on GKE.
Simplifying Deployment Pipelines from 'Build' to 'Release' using HashiCorp Waypoint
Deploying applications in the DevOps landscape can be confusing with so many services, configuration files, and workflows to decode. Specially, it becomes even more confusing when we need to identify different tools at different phases of the application lifecycle. With this context in place, I want to introduce a pipeline build using a single configuration file (written in HCL) that uses Hashicorp's newly introduced open source project 'Waypoint' together with 'Buildpacks' (CNCF project) for providing runtime on a Kubernetes environment . The talk will be accompanied with a quick demo to show the complete workflow from build -> deploy -> release phase of the software that is released for end user.
Simplifying and securing the DevX experience with Buildpacks & Cosign
DevSecOps teams love containers! It is a foundational technology that can improve development velocity, operational efficiency and reduce risk. However, realizing these outcomes can be a challenge especially if you have containers built by hand or with disparate processes across your engineering teams.
Most proven solution around building application image is using Dockerfile that requires some amount of manual efforts. These homegrown container build pipelines start showing rough edges as container usage scales into the hundreds and thousands, making a developer's or an end user's life miserable as dockerfile-based containers are hard to productionize and scale. This also has a security impedance in supply chain which has to be taken care of. Developers struggle to maintain complicated dockerfiles, while operations teams face ongoing challenges to track the myriad dependencies and OS patch levels across a container fleet.
In this talk, I am going to present an approach simplifying the developer/devops experience through Buildpacks , more precisely with 'kpack' on a cloud-native platform (Kubernetes) together with image verification and identification through Cosign.
Guardians of the MLOps Galaxy: Simplifying Deployments with Buildpacks
Machine learning platforms aim to streamline the workflow for ML practitioners, allowing them to focus on developing their models while the platform handles repetitive tasks like packaging code, dependencies and configurations. Traditional methods using Dockerfiles require ML engineers to navigate complex Linux processes and maintain multiple Dockerfiles for different projects, which can be time-consuming and prone to errors. Additionally, security mandates for regular patching and updates adding further to the complexity.
Join this talk to explore how Cloud Native Buildpacks can simplify and secure MLOps deployments. By automating the packaging of ML projects, including custom libraries and hardware specifications, Buildpacks enhance flexibility, maintainability and security. This approach reduces the operational burden on both developers and security teams, ensuring a more efficient and scalable MLOps deployment process
Taming the Multi-Cluster Sprawl: Add-on Automation with Project Sveltos
As Kubernetes adoption scales, platform and SRE teams face growing challenges in managing add-ons, configurations, and policies across large fleets of clusters. Manual scripting or ad-hoc automation often results in configuration drift, inconsistent deployments, and operational overhead — especially in hybrid or multi-tenant environments.
This session introduces Project Sveltos, an open-source solution designed to centralize and automate multi-cluster add-on management. Controlled from a single management cluster, Sveltos applies GitOps principles to ensure consistent deployment, synchronization and policy enforcement across any number of Kubernetes clusters, whether on-premises or in the cloud.
We'll dive deep into the Sveltos Addon Controller, the core component responsible for automating the deployment and lifecycle management of add-ons such as Helm charts, Kustomize templates, and raw YAML manifests. The session will also explore ClusterProfiles and Profiles, which enable dynamic, label-based cluster targeting and fine-grained, tenant-specific customization — ensuring self-healing, compliant configurations across the fleet.
The talk will include a brief architectural overview, a live or visual demo of add-on synchronization, and real-world usage patterns that simplify day-2 operations for platform teams.
Key Takeaway for the Community:
- Attending this session will equip participants with practical strategies to streamline multi-cluster Kubernetes operations using Project Sveltos
- Participants will learn how to eliminate configuration drift, reduce manual effort, and enforce compliance across hybrid or multi-tenant environments
- The session will empower platform and SRE teams to achieve self-healing, scalable, and resilient Kubernetes fleet management from a single control plane
