Our Next Frontier in Cloud Networking

When Arista launched Cloud Networking in 2008, many did not grasp its profound impact. Today it is an industry reality, with 750+ worldwide customers deploying Arista’s cloud network (leaf-spine) design model. As traffic patterns shifted rapidly from north-south client-server to more horizontal east-west server-to-server traffic, the two-tier cloud network was born and became mainstream for…

Big Data Needs Cloud Networking

Over the past three years computing architectures have bifurcated, resulting in markedly different network architectures for legacy enterprise and next generation cloud network data centers. Arista has been a leader in championing cloud networks that respond to two key trends. The first driver has been server virtualization, which literally rewrote the rules on server architecture,…

A Redefining Step in Low Latency Networking

The race to zero latency networking continues – millions of transactions in real time. It has challenged traditional constructs for High Frequency Trading (HFT) markets and creates an insatiable appetite to shave every nanosecond of latency to achieve the least possible round trip delay. Traditional Ethernet switches, even recently touted ones, continue to be a…

A to Z Cloud Networking with Zero Touch Provisioning

As Cloud Computing continues to become mainstream, the operational models around remote public and local private cloud management need careful attention. Arista has been leading the charge in highest density 10Gbe switches with the least footprint, lowest power and lowest latency scaling to 10000+ nodes. Looking ahead, our customers expect more than speed and density…

Is Cloud Networking Disruptive to Traditional Networking?

The rise in cloud computing and virtualization is pushing the envelope of cloud networking scale. Several dimensions of networking have been pressured simultaneously: number of connected servers, connection performance and predictable performance. Well-established network protocols now need a new look. Protocols such as ARP (Address Resolution Protocol) broadcasts, and STP (Spanning Tree Protocol) worked well…

Cloud Networking Reflections

As I ponder upon the many assertions I have made in my blogs in the past year, I know the reality of my assertions is much more pertinent! So lets take a walk down the 2010 memory lane to judge how I really fared with my 2010 predictions. Prediction #1: The rise in cloud computing…

The Power of Extensible Open Cloud Networking

The definition of clouds continues to be both an evolving and important era in IT. Unlike the static and well-defined enterprise world of the past decades, the nature of resources and applications are more dynamic depending greatly on compute needs, workloads and user access. A common myth is that clouds only make sense for public…

Virtual Machines – The new unit for Cloud Networking

The rise of server virtualization has generated an exponential increase in virtual machines (VM), and in the associated virtual switches (vSwitch) used to manage them at this new network access layer. Yet the methods and tools available to operate and coordinate this new virtual network with the overall physical network are at best cumbersome, and…

Applications are Driving Traffic Patterns in Cloud Networking

As we enter the second half of 2010, I sense that an architectural shift in data center environments has begun replacing traditional constructs. Traffic Patterns are rapidly shifting from the traditional North-South client server model to an East-West server to server. As this shift occurs, it is even more important to assess the impact of application…
