The world is expeditiously moving to the cloud to achieve greater agility and economy, following the lead of the cloud titans. Arista’s revolutionary innovations in software-driven cloud networking are propelling this dynamic transformation that weaves private, public and hybrid clouds into a seamless single-image network. Avant-garde applications including artificial intelligence, social media and big data, coupled with emerging architectures such as, dense server virtualization and IP Storage have placed enormous demands on the network infrastructure in datacenters.

Key transformations include:

  • Architectures are transforming the enterprise, extending to the campus and branch, converting siloed places in the network to a cloud first strategy resulting in places in the cloud.
  • Applications are changing to new standards and methodologies for agility and elastic demand, blending cloud native and business worlds.
  • Traffic patterns of the past are supplanted by highly distributed applications that drive east-west traffic for workloads, workflows, and workstreams and disparate devices.
  • The pressing mandate facing cloud-scale to enterprise providers is easy portability between different AI workloads without compromising cycle time.
  • Datacenters are moving to microservices, be they physical, virtual and containerized models.
  • Demands for hitless upgrades and high availability are mandatory with automatic rollback and uninterrupted services. 

Network architectures, and the network operating systems that make the cloud possible, need to be fundamentally different from the highly over-subscribed, hierarchical, multi-tiered and costly legacy solutions of the past.

Arista Purpose

Arista Networks was founded to deliver software-driven cloud networking for cloud scale, cloud class and hybrid cloud networking environments. Unlike intent-driven methodologies, Arista’s portfolio is based on cognitive and software-driven principles for cloud networking.

Arista, a pioneer and market leader in cloud networking, has emerged as one of the fastest growing companies in the industry. Arista has more recently forayed into the routing arena that offers another multi-billion dollar market opportunity. Arista has disrupted the market with two significant innovations. Arista’s principle invention is an advanced network operating system, Arista EOS® (Extensible Operating System), that is built from ground-up on a standards-based open architecture that delivers high reliability and unique programmability at all system levels, allowing integration with third-party ware to achieve best-of-breed solutions in multi-vendor networks. Topping it, EOS offers a cross-cloud network platform that automates IT workflows or videobased workstreams, provides network-wide visibility, and faster problem resolution.

Arista’s other key innovation is the exclusive use of best-of-breed merchant silicon that enables open standards-based networking with rapid time-to-market. Notably, our merchant silicon family from several vendors, delivers state-of-the-art platforms that provide greater price/performance enabled by technology advances associated with Moore’s Law. In stark contrast, legacy approaches typically have relied on custom ASICs that are tightly coupled with monolithic software – resulting in vendor lock-ins, and proprietary costly choices. The figure below illustrates Arista’s revolutionary approach of universal cloud networking.
