Built by Engineers. Scaled for AI.

The Arista Cloud Builders are one-day, technical deep-dive events held across EMEA. This year, we explore the transition to the AI Center, examining high-performance 800G platforms and the evolution of the Modern Operating Model. Through practical demonstrations of EOS®, CloudVision, and NetDL, we’ll showcase how Arista is simplifying scale, automating routing, and securing the campus with a unified, self-healing fabric designed for 2026’s most demanding workloads. 

Why Attend?

Design for high-demand workloads

Networking requirements are shifting rapidly as AI and high-density computing go mainstream. We’ll look at the specific architectural shifts, like high-radix designs and specialized Ethernet, needed to keep data moving efficiently without overcomplicating your fabric.

Refine your operational workflow

Get a hands-on look at how to replace repetitive manual tasks with reliable, intent-based operations. By using EOS and CloudVision for real-time telemetry, you can move toward a model where the network reports its own health and helps you resolve issues before they impact users.

Exchange notes with the local community

This is a technical, peer-led forum focused on how things actually work in production. You’ll spend the day with other EMEA-based engineers to discuss practical deployment strategies and honest lessons learned, helping you build a network of contacts you can reach out to whenever you hit a wall.

Topics Covered

Arista's Data Center Update - Networking for What's Next

In this session, we will explore the transition from traditional cloud networking to the AI Center, where the network becomes the high-performance central nervous system powering massive GPU clusters. Through open, Ethernet-based innovation led by the Ultra Ethernet Consortium, combined with EOS-powered 800G platforms and breakthrough XPO liquid-cooled optics, we remove the networking bottlenecks that limit AI scale. This evolution is further enabled by AVA and NetDL, which integrate AI-driven telemetry and self-healing capabilities to ensure the massive scale and power density required for 2026’s generative AI workloads remain both manageable and efficient.

Delivering Scalable and Intelligent Networking Solutions

Discover how building future-proof infrastructure grows seamlessly alongside the world's most demanding workloads. By combining high-performance hardware with the cognitive power of CloudVision and NetDL, you can transform the network from a static asset into an intelligent, data-driven fabric. This approach focuses on maximizing operational efficiency through deep telemetry and automated troubleshooting, ensuring that whether you are scaling a boutique enterprise or a massive AI-driven cloud, the network remains agile, self-aware, and consistently reliable.

Transform Your Enterprise Network with Arista's Modern Operating Model

Discover how Arista's Modern Operating Model can transform your enterprise network by driving agility, automation, and data-driven decisions across cloud-native infrastructure. By breaking down silos and embracing innovation, we can help you deliver faster time-to-market, consistent outcomes, and resilient operations at scale.

Arista's Campus Revolution: Highly Availablity, Zero Touch Operations & Zero Trust Network Security

In this session, we will look at Arista’s Cognitive Campus and how it represents a fundamental shift toward treating the enterprise campus like a modern cloud data center. By leveraging a unified EOS software stack, we’ll show you how to eliminate the complexity of traditional campus architectures through Zero Touch Provisioning (ZTP) and automated workflows that simplify day-to-day operations. Prioritizing High Availability through resilient, non-blocking fabric designs and integrating Zero Trust Network Security directly into the infrastructure, using macro and micro-segmentation to ensure every device and end user is continuously validated regardless of location.

Arista Routing: Technical Strategy

In this session we’ll summarize the transformation of traditional, monolithic routing into a modern, cloud-scale architecture built on merchant silicon with a single software image (EOS). The strategy focuses on replacing complex, proprietary legacy routers with a Universal Spine and Cloud Edge approach that leverages high-density 100G/400G/800G platforms for peering, core, and WAN transit. By utilizing open standards like EVPN and Segment Routing, Arista provides a programmable Global Transit Fabric that delivers internet-scale route tables and massive throughput while significantly reducing power, space, and operational costs through CloudVision automation and deep, real-time telemetry.
