Arista Networks

Arista Networks, Inc. is an American computer networking company headquartered in Santa Clara, California, that designs and sells multilayer network switches to deliver software-defined networking for large datacenter, cloud computing, high-performance computing, and high-frequency trading environments. Founded in 2004 by industry veterans Andy Bechtolsheim, Kenneth Duda, and David Cheriton, Arista has emerged as a pioneering force in cloud networking, challenging established players with innovative technology and a customer-centric approach.

At the heart of Arista's success is its revolutionary Extensible Operating System (EOS), which runs as a single image across all Arista devices. EOS represents a fundamental reimagining of network operating systems, incorporating Software-Defined Networking principles with AI-enabled capabilities and a holistic network view through its Network Data Lake architecture. The platform's resilience, programmability, and advanced features have made it the preferred choice for hyperscale cloud providers and enterprises deploying AI infrastructure.

Arista went public in June 2014 on the New York Stock Exchange under the symbol ANET and has since grown into a market leader with over 10,000 cloud customers worldwide and more than 100 million deployed ports. The company's customer base includes the world's largest cloud providers, with Microsoft and Meta each spending over $1 billion annually with Arista. In 2024, Arista generated $7.0 billion in revenue, representing 19.5% growth, with a market capitalization exceeding $160 billion as of late 2025.

Under the leadership of CEO Jayshree Ullal, who joined in 2008, Arista has expanded beyond its data center roots into campus networking, branch networking, and SD-WAN markets. The company's July 2025 acquisition of the VeloCloud SD-WAN portfolio from Broadcom for approximately $1 billion marked a significant strategic expansion into AI-driven enterprise networking. Arista expects AI-related networking revenue to exceed $1.5 billion in 2025, positioning the company at the forefront of the AI infrastructure revolution.

The company operates with a distinctive culture known as "The Arista Way," emphasizing respect, integrity, innovation, and an entrepreneurial spirit. With 4,412 employees as of 2024 and recognition as #15 on America's Best Companies 2025 list, Arista continues to deliver exceptional innovation while maintaining the agility and customer focus that defined its founding vision. The company's commitment to quality over artificial deadlines, automation-driven productivity, and cultivating pride without arrogance has created a workplace environment that consistently ranks in the top 5% compared to similar-sized companies.
