The Four Pillars of Software-Defined Cloud Networking

Software-defined networking, an exciting buzz word these days really means different things to different folks. Often Openflow, ONS (Open Network Stack) and various controller approaches are touted as the promised land of software-defined networking. The term “Fabric” touted by many vendors, creates further confusion on proprietary ways on its benefits and significance. At Arista we…

Cloud Networking vs Enterprise Networking – Are We Stretching Investment Protection?

Networking vendors and the IT industry have touted investment protection as a key attribute for many years. This combined with price/performance/scale and a feature-laden network operating system, IOS, has been the key advantage of Cisco for multiple product generations. Cisco has been the pioneer and leader of the enterprise market in the 1990’s with Cisco…

The March to Merchant Silicon in 10Gbe Cloud Networking

The inevitable march towards merchant silicon for Ethernet switching is continuing with the announcement from Intel today that it is acquiring Fulcrum Microsystems. Fulcrum of course the silicon vendor that is the core of our low-latency switch family that is the most widely used switch across the world for high-frequency trading. I wanted to share…

Big-Data is a Big Deal for Cloud Networking

Once again new applications are pushing the envelope for modern cloud networking, a radical departure from traditional enterprises! Big Data was a hot topic at the GigaOm Structure conference last month. As companies acquire and analyze vast amounts of structured and un-structured data, they increasingly re-engineer their data centers for new applications, which in turns…

Software-Defined Cloud Networking: Hype or Reality?

I have been pleasantly surprised by the rapid adoption in data centers of cloud networking architectures in just the past two years. Cloud computing has stressed the ability of the network to scale in previously unimagined ways, challenging just about every traditional switch metric from the size of L2/L3 address tables, destination address flooding, increased…

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…
