In containerized environments like Kubernetes, service mesh has emerged as a key architectural component to ensure reliable, secure, and observable communication between services. Despite the growing popularity of service mesh, many developers, operators, and architects find the concept of a service mesh intimidating due to its perceived complexity and wide array of features.
In this talk speaker from the gRPC team in Google will demystify service mesh technology by returning to the basics, providing clear understanding of what a service mesh is, the problems it solves, and how it fits into a cloud-native ecosystem. Additionally, this talk will explore the differences between proxy-based and proxyless service mesh architectures, discussing their advantages, disadvantages, and use cases.
We spend countless hours making applications resilient and scalable, but often overlook their final moments. While we obsess over startup performance and runtime behavior, the shutdown process remains a mystery. Yet, understanding this crucial phase can mean the difference between clean service transitions and disrupted user experiences.
Join us as we decode Pod termination in Kubernetes, exploring the lifecycle from shutdown signal to final goodbye. We'll examine real-world scenarios through kubectl, kubelet, and API interactions, and share practical strategies for smooth shutdowns. Transform your chaotic Pod terminations into choreographed farewells and enhance your application's reliability.
For: DevOps engineers, SRE teams, and Kubernetes developers.

Kubernetes is powerful, but its true strength lies in extensibility. Many developers struggle to adapt it to their needs, often resorting to workarounds instead of leveraging built-in extension mechanisms. What if Kubernetes worked for you, not the other way around?
This beginner-friendly session will introduce you to Custom Resource Definitions (CRDs) and custom controllers, guiding you through their design, implementation, and deployment. You'll learn how to create Kubernetes-native abstractions that automate workflows, simplify operations, and enhance the developer experience. We'll cover best practices, automation strategies, and performance optimizations to ensure scalable and maintainable extensions that integrate seamlessly with Kubernetes.
Get ready to move beyond workarounds and let your pods thrive with clean, scalable, and native Kubernetes extensions!

Edge computing is still a fairly new area in the cloud native tech industry and is growing fast. As computing moves to the edge, what does Kubernetes look like beyond the cloud, and why does it matter?
This session features a live demo with a Raspberry Pi, camera, and real-time AI detection. Watch as our edge device identifies raised hands, sends data to a Kubernetes cluster via KubeEdge, and visualizes results instantly.
We'll explore: - Edge Kubernetes challenges: connectivity, resources, security - KubeEdge's approach to decentralized workloads - Real-world applications across industries
Join us to see how AI, Kubernetes, and edge computing converge to enable powerful new possibilities.

This session delves into Zomato's journey of adopting Kuma Service Mesh to manage over 500 microservices with 10,000 dataplanes. The session begins by addressing common challenges in service communication, such as observability gaps, insecure traffic, and inconsistent configurations across environments, and explore how Kuma Service Mesh resolves these issues.
The presentation highlights how Kuma standardises configurations, minimises debugging efforts, and improves application performance, thereby reducing developer overhead. A key focus is on leveraging Kuma to enhance developer workflows through local-preview environments, allowing dynamic traffic routing to local services based on headers. This facilitates rapid iteration and debugging.
Additionally, we will discuss our roadmap for utilising Kuma's zone-aware routing to reduce cross-zone data transfer, lowering costs and enhancing efficiency.

This session will explore why NFTables offer clear advantages over IPTables and IPVS, especially in large-scale production environments from both maintainers and end users perspective. We’ll share a user story who faced persistent issues with IPTables, saw some success with IPVS, and finally solved their scalability problems by migrating to NFTables. From a maintainers perspective we will showcase how and why NFTable outperforms the other proxy modes. We’ll provide performance insights and discuss kernel compatibility. We will also discuss NFTables compatibility with various CNI providers and plugins, and how NFTables support is already integrated in many environments, providing a smoother transition. Attending this session you will get an indepth understanding of behavioral changes when migrating from IPTables and IPVS to NFTables, including key metrics to track.
