ARISTA Network



Arista Networks wurde 2008 vom deutschstämmigen Internet-Pionier Andreas von Bechtolsheim gegründet um richtungsweisende Produkte für die Bereiche Data Center und High Performance Computing auf den Markt zu bringen. Das Portfolio beinhaltet Gigabit und 1/10/40-Gigabit-Switches, welche maximale Flexibilität und Erweiterbarkeit ermöglichen und dabei ein hervorragendes Preis- / Leistungsverhältnis bieten.

Kern aller Arista-Produkte ist das Extensible Operating System (EOS), dessen offene, moderne Architektur u,a. unterbrechungsfreie Upgrades und die Implementierung eigenständiger Linux-Applikationen ermöglicht.

Arista Networks was founded to bring the power of software innovation to large data center and high-performance computing environments. We provide rich cloud networking solutions to large-scale Internet companies, cloud service providers and enterprises building next-generation data centers. We deliver our software, EOS (Extensible Operating System) and network applications, on 10/40/100 GbE platforms

The world is moving to the cloud to achieve better agility and economy, following the lead of the cloud titans who have redefined the economics of application delivery during the last decade. Arista’s innovations in cloud networking are making this possible. New, modern applications such as social media and Big Data, new architectures such as dense server virtualization and IP Storage, and the imperative of mobile access to all applications have placed enormous demands on the network infrastructure in data centers.
Arista Networks was founded to deliver software-driven cloud networking solutions for these large data center and cloud computing environments. Arista is focused on building 10/40/100 Gigabit Ethernet (GbE) switches that redefine network architectures, bring extensibility to networking and dramatically change the price/performance of data center networks
Arista has disrupted the market for high-speed data center switches with two principal innovations. Our core innovation has been to build a better network operating system, AristaEOS®(Extensible Operating System), which we have built from the ground up using innovationsin core technologies since our founding in 2004. We now have more than 8 million lines of code and over 1000 man-years of advanced distributed systems software engineering in ouroperating system. EOS is built to be open and standards-based, and its modern architecture delivers better reliability and is uniquely programmable at all system levels. EOS provides anideal platform for our customers to automate their IT workflows, while integrating with 3rd parties to achieve best-of-breed solutions in multi-vendor networks. EOS also enables ourcustomers to gain visibility across their physical and virtual networks
When we began to build EOS, wewanted to address two fundamental issues that exist in cloudnetworks: the need for non-stop availability and the need for high feature velocity coupled to high quality software. Drawing on our engineers experience in building networking products over more than 30 years, and on the state-of-the-art in open systems technology and distributed systems, Arista started from a clean sheet of paper to build an operating system suitable for the cloud era.


Hyperscale cloud providers are driven by the need to cost-effectively and rapidly roll out new services and features to their customers. Microsoft, for example, stated at a Cloud “State of the Union” event in October of 2014 that they deployed 300 major new features and services on Azure in the preceding 12 months–an average of 6 per week. This level of innovation requires not only rapid new feature velocity from network infrastructure vendors, which Arista EOS provides, but also the ability to customize IT workflows and program the infrastructure directly. While our EOS architecture is state of the art today, we are constantly investing in our core infrastructure to provide the capabilities required for building modern cloud networks. New use cases in Cloud and Service Provider networks and hybrid cloud deployments in Enterprises require on-going upgrades and extensions to our state oriented architecture. Arista has evolved EOS forward by extending SysDB into NetDB™, enhancing scalability, visibility and control on a network-wide basis, all while staying true to our core values of reliability, open standards and programmability
