Any Cloud Platform Product Overview

 

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:

  • vEOS Router: Built for production environments, the vEOS Router is optimized for virtual and public cloud environments and is designed to offer multi-gigabit throughput. Please refer to the datasheet for further information
  • vEOS-lab: vEOS-lab is meant for simulation and testing purposes. Please refer to the datasheet for further information

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.
