A New Frontier: Sidecarless Service Mesh on Windows With Istio's Ambient Mesh - Keith Mattix & Mitch Connors, Microsoft
Tuesday April 1, 2025 13:35 - 14:00 BST
Over the past 8 years, service meshes have provided the Kubernetes and CNCF ecosystems with the networking capabilities necessary for a robust microservice architecture. However, Windows container users have often been unable to take advantage of these features because of the deep Linux dependencies. Until now.

In this talk, you'll learn about past efforts to bring service mesh to Windows, and how Istio's ambient mesh opened the door for a maintainable path forward for a sidecarless deployment topology. We'll learn how Rust, Envoy, and maybe even eBPF can bridge the gap between Linux and Windows for service mesh.

Architecting Istio for Large-Scale Deployments: R&D and Service Mesh Grow Together- Lior Lieberman, Google & Erik Parienty, Riskified
Tuesday April 1, 2025 14:10 - 14:35 BST
Managing Istio at scale presents challenges familiar to many R&D teams. From handling the growing complexity of routing configurations to responding to developer requests, the operational burden on DevOps and infrastructure teams can easily become overwhelming. While questions like “how do you let developers manage routing independently while keeping production safe?” are commonly discussed, running Istio at scale quickly makes the list of considerations grow out of control.

This talk dives into how Riskified’s infrastructure team tackled these challenges. From simple use cases of self-service traffic management to advanced implementations of cost efficiencies and topology-aware routing, you’ll hear what went wrong, what worked, and the lessons learned along the way.

Whether you’re scaling your mesh or seeking ways to streamline Istio management, this talk will equip you with practical tools and strategies to navigate the complexities of Istio at scale.

⚡ Lightning Talk: Troubleshooting Istio Ambient With Kiali 2.0 - Josune Cordoba & Hayk Hovsepyan, Red Hat
Tuesday April 1, 2025 14:50 - 15:00 BST
We will showcase how Kiali 2.0 enhances support for Istio Ambient Mesh and the Gateway API through a demo, providing advanced observability and management for Kubernetes environments. Deploying a sample application with traffic and network policies, we’ll use Kiali's interface to gain insight into traffic paths, Ambient Mesh components, and Istio configurations. With Kiali's new configuration wizards, managing Gateway API routing is streamlined, making it simple to set up and adjust traffic routes. By the end of the session, you'll gain a clear, simplified understanding of mesh infrastructure using Istio Ambient, demystifying the complexity of the Service Mesh.

Navigating the Maze of Multi-Cluster Istio: Lessons Learned at Scale - Pamela Hernandez, BlackRock
Tuesday April 1, 2025 15:20 - 15:45 BST
Considering an Istio multi-cluster setup? Hear real-world lessons on balancing security with operational complexity, scaling configurations to hundreds of clusters, and designing for resilience and observability. Lessons learned from managing hundreds of clusters serving millions of requests per day.

Adopting Istio in Kubernetes deployments often starts as an exciting journey, but challenges arise when scaling to support millions of services—issues not covered in basic guides.

This talk dives into the complexities of implementing a multi-cluster Istio service mesh at scale, covering a hub-and-spoke model. Key challenges include: ensuring secure client isolation; load balancing across different types of clusters; managing failover; and automating cluster lifecycle.

Whether you're planning your first multi-cluster Istio deployment or struggling with management at scale, this talk will provide actionable strategies to overcome the pitfalls of large-scale service mesh implementations.

A Service Mesh Benchmark You Can Trust - Denis Jannot, solo.io
Tuesday April 1, 2025 15:55 - 16:20 BST
Service Mesh unlocks powerful capabilities for Kubernetes, enhancing observability, security, and traffic control. However, concerns about complexity and overhead have slowed adoption. This session debunks those myths! We’ll showcase how Service Mesh technologies have matured, offering approachable solutions with minimal impact. Istio’s Ambient mode exemplifies this shift, minimizing operational complexity and overhead. Many existing benchmarks raise doubts due to conflicting results. This session tackles this head-on! We’ll run a live, representative benchmark at scale (10s of nodes, thousands of Pods, thousands of RPS throughput) and dissect the metrics with the audience.

⚡ Lightning Talk: Optimise Your Mesh With Istio Sidecar - Maggie Slukova, GetYourGuide
Tuesday April 1, 2025 17:15 - 17:25 BST
In an Istio service mesh, all workloads have to be continuously kept up to date with the latest cluster configuration. However, only few or no workloads communicate with every other workload. Keeping superfluous information up to date across the whole cluster creates unnecessary load and increases the cluster convergence time, which results in errors.

One way to optimise this behaviour is by leveraging the Istio Sidecar resource. Workloads specify egress hosts for the services they need to communicate with, updates are then sent only when an egress host IP address changes.

This talk will cover GetYourGuide’s adoption of the Istio Sidecar resource - trade offs of the implementation; rolling out high criticality configuration changes in a live cluster.

We will showcase how we reduced cluster convergence by 10x and eliminated all lag related networking errors by rolling out the Istio Sidecar resource across ~300 services without any incidents and with very little time investment.
