ARISTA

Leading the Way in Data-Driven Cloud Networking

Our Technology: EOS and Data-Driven Networking

Arista Networks is recognised as an industry leader in data-driven, client to cloud networking. We provide networking solutions for large data centre/AI, campus, and routing environments. Our award-winning platforms are designed to deliver availability, agility, automation, analytics, and security through an advanced network operating stack.

Arista was founded by industry luminaries Andy Bechtolsheim, Ken Duda, and David Cheriton. The company was launched in 2008 and is led by CEO Jayshree Ullal. Our seasoned leadership team is globally recognised as respected leaders and visionaries with extensive history in networking and innovation.

We have offices around the world and are headquartered in Santa Clara, California.

Our Technology: EOS and Data-Driven Networking

At the core of Arista's platform is Arista EOS®. EOS is a modular switch operating system built on a standard Linux kernel. It features a unique state-sharing architecture that cleanly separates switch state from protocol processing and application logic. All EOS processes run in their own protected memory space and exchange state through an in-memory database. This architecture provides robust, reliable data centre communication services while delivering security, stability, openness, modularity, and extensibility. It also forms the foundation for in-service software updates and self-healing resiliency.

EOS is an open and programmable platform, offering programmability at all layers, including eAPI, EOS SDK, Linux, DevOps integration, and broad scripting support. We also offer vEOS, which extends the EOS platform to VM-based hypervisor environments like VMware ESX, KVM, and Oracle Virtualbox. vEOS allows for network design and validation, rapid development and testing, and training initiatives in a virtual environment, as it's the exact EOS implementation that runs on hardware.

Arista's core technology, combined with strategic acquisitions, has transformed the company into a data-driven cognitive cloud networking company. We deliver AI value through the network.

Customer Success and Market Leadership

Arista serves a prestigious set of customers, including Fortune 500 global companies in markets like cloud titans, enterprise, financials, and specialty cloud service providers. We deliver products worldwide through distribution partners, systems integrators, and resellers.

Customers have highlighted the benefits of our network approach, including the ease of use of our APIs and GUI compared to traditional CLI-driven offerings, which helps quickly onboard non-technical staff and supports DevOps. Our Converged Cloud Fabric (CCF) has been successfully deployed, enabling switches to be running within hours due to auto-configuration intelligence.

Arista is consistently ranked #1 in market share for Data Center Switching by networking analysts. We have received more than 100 awards from leading publications, analysts, and institutions.
