Using CloudVision Portal to Manage Arista AnyCloud

Posted on February 4, 2019 by   |   238 Views

Introduction There are many advantages to using Arista’s vEOS Router and CloudVision Portal (CVP) in hybrid cloud environments. Among those advantages are: Arista EOS is a proven and stable network operating system used in some of the largest networks in the world. The same EOS that runs on our physical switches also runs in the public cloud. CloudVision Portal provides a common management model for network devices whether running in a customer’s private data center or in public cloud environments. CloudVision Portal provides turn-key automation and real-time telemetry across private and public cloud environments. One of the primary challenges to...

Deploy a Transit VPC with vEOS using IGW (Public IP)

Posted on November 30, 2018 by   |   533 Views

Deploy a Transit VPC with vEOS using IGW (Public IP) fanyang@arista.com   This document focuses on the steps to build a Transit VPC solution using Internet Gateway (IGW) vs. VPC peering. There are certain advantages to use IGW as transport. This eliminate the limits on how many VPC peering can be created and gives customer a larger scale deployment. It also enables spoke VPCs to communicate with each other directly with one hop, which can potentially save data cost. Besides, even it’s public ip to public ip communication, if both IPs belong to AWS, AWS will route the traffic through...

Arista Any Cloud Platform – vEOS Router in Azure Deployment Guide

Posted on August 20, 2018 by   |   238 Views

Introduction In this document, we will demonstrate the deployment of Arista’s vEOS Router in Microsoft Azure. A vEOS Router can be leveraged to implement various Azure architectures such as the transit-edge or hub-spoke architecture. This particular document provides a step-by-step guide to deploy vEOS Router in a transit-edge architecture in the Azure public cloud. Overview Arista’s private and public cloud infrastructure both offer significant efficiencies that make it a compelling option for workload placement.   We have proven this in the private cloud with a simple yet scalable Spine/Leaf topology utilizing industry standard protocols across all of Arista switches. With...

Arista Any Cloud Platform – VM Migration

Posted on July 2, 2018 by   |   201 Views

Introduction In many scenarios, resources are provisioned in the public cloud as a service, without a need to connect to a private on-prem environment. Situations will arise where connectivity is required between a public and private environment that conflict in IP space. This article will showcase how to leverage vEOS Router in AWS to establish connectivity between a VPC and a private on-prem datacenter that conflict in IP space. In this particular example, there are a hand-full of VMs that need to be migrated from AWS to a private environment. Objective Establish connectivity between the AWS VPC and the private environment. Once connectivity is established,...

Arista Any Cloud Platform – Destination NAT (IP Anycast) in vEOS Router

Posted on May 30, 2018 by   |   892 Views

Overview Purpose of this post is to test and validate Destination NAT (IP Anycast) support on vEOS Router.  We built the following topology in AWS to validate this setup:    Here is the link to the EOS Central article that can be referenced to help build this topology – https://eos.arista.com/arista-any-cloud-platform-hybrid-cloud-veos-router-in-aws-deployment-guide/ Objectives We hope to accomplish  the following in this article: Create a Loopback interface on vRouter-1a and vRouter-1b with an IP address of 1.1.1.1/32 Advertise 1.1.1.1/32 as an equal cost route to vRouter-Transit.  At any given moment vRouter-Transit could take the path to vRouter-1a or vRouter-1b.  In this setup we utilized BGP without...

Arista Any Cloud Platform – Security Use Case

Posted on January 9, 2018 by   |   426 Views

Introduction In this document we will demonstrate how to effectively leverage Arista’s vEOS Router in a Transit – Edge VPC model to satisfy a common security use case. As most companies look to move into the public cloud space, security vulnerabilities have gained more focus than ever before. Objective Provide a centralized security model within an AWS region, which will allow for ease of visibility and control. Deploying separate AWS Internet Gateways in every VPC, increases complexity and vulnerabilities in the public cloud space.  Prerequisites This document assumes that you have the following architecture deployed: A Transit – Edge VPC topology deployed...
