Arista Extensible Operating System (EOS®) is the core of Arista cloud networking solutions for next-generation data centers and cloud networks. Cloud architectures built with Arista EOS scale to hundreds of thousands of compute and storage nodes with management and provisioning capabilities that work at scale. Through its programmability, EOS enables a set of software applications that deliver workflow automation, high availability, unprecedented network visibility and analytics and rapid integration with a wide range of third-party applications for virtualization, management, automation and orchestration services.
Arista EOS is a fully programmable and highly modular, Linux-based network operation system, using familiar industry standard CLI and runs a single binary software image across the Arista switching family. Architected for resiliency and programmability, EOS has a unique multi-process state sharing architecture that separates state information and packet forwarding from protocol processing and application logic.
The Arista vEOS Router is a core component of Arista’s Any Cloud Platform. The vEOS Router is Arista’s same, proven single EOS software image, offered as a multi-cloud and multi-hypervisor virtual router. This cloud-grade and feature-rich software platform empowers enterprises and service providers to build consistent, highly secure and scalable cloud networks. Arista vEOS router is designed to support any public or hybrid cloud environment, including Amazon Web Services (AWS), Microsoft Azure Cloud, Microsoft Azure Stack, Google Cloud Platform, and Oracle Cloud Infrastructure.
The vEOS Router leverages existing EOS proven routing capabilities and includes enhancements, such as IPSEC VPN tunnelling, to securely interconnect workloads across multi-cloud deployments. In addition, vEOS Router is integrated with cloud provider APIs to enable seamless deployment, automation, analytics and end-to-end visibility.
Arista vEOS Router fully integrates with Arista CloudVision to simplify the experience of using cloud services by leveraging a network-wide approach for workload orchestration and workflow automation together with network telemetry for hybrid cloud networking. With an unmatched level of consistency, Arista’s customers can reduce their operational costs when deploying the Arista Any Cloud across on-premises enterprise datacenters, private clouds and public clouds.
Arista offers virtualized EOS through two different offerings:
Key Platform Benefits of vEOS Router
Highly Available Architecture: Architected for resiliency, EOS has a unique multi-process self-healing state sharing architecture that minimizes downtime with fault containment to a single module and process restart without the need to rebuild state information.
Cloud Grade Routing: Arista vEOS Router delivers a routing stack that is capable of running on a variety of hypervisors and in multiple clouds. With the same proven single EOS software image that runs across all Arista products, vEOS Router extends the consistent operational model from existing datacenter network deployments
DevOps, NetOps and 3rd Party Support: Arista EOS was built with programmability at every layer of the software stack for easy integration and customization. Arista vEOS Router enables the same programmatic control of the network with numerous programmability options. Tighter NetOps/DevOps integration is possible with rich, well-structured set of APIs.
Simplified Management with Monitoring and Reporting: vEOS Router can be managed through Command Line Interface (CLI), APIs, or CloudVision network-wide automation services. It also presents comprehensive logging and diagnostic information that can be monitored using industry-standard tools and NetDB real-time state streaming. It is also fully integrated with cloud-native monitoring and automation solutions.
EOS+ is a software platform for network programmability. EOS+ enables programmatic control of the network with end-to-end solutions, providing customers the ability to automate their network for reduced operational cost and improved responsiveness for managing workloads and workflows. EOS+ offers pre-built applications from Arista and a wide variety of partners with the ability to customize directly or with assistance of Arista EOS Software Consulting services. EOS applications provide complete solutions with support from Arista’s Technical Assistance Center (TAC).
