Application Based Cloud Networking – The Next Frontier

Networking over the past two decades has mostly been about raw connectivity. Rarely have applications been tuned and optimized to truly take advantage of the network. People have been talking about this vision for years but few have gone much beyond just talking. The reason is that it takes a radical departure from today’s closed…

The Fabric Hype Versus Cloud Networking Simplicity

As we enter 2012, the networking industry faces much need for a return to focusing on simplicity and standards amidst the confusion created by proprietary vendor-specific architectures. Cisco waxes eloquent about scaling large data center networks with “FabricPath”. Juniper discusses the laws of physics with “QFabric”. Brocade talks about “One” Fabric as a unique concept….

The Role of 10GBASE-T and 40GbE in Cloud Networking

10GbE continues to make strides into data centers. The massive data explosion triggered by bandwidth-heavy content such as video, high-resolution images and multimedia has placed pressure on the data transfer rate capability of cloud networks. Faster networks, denser storage and ever more powerful servers further contribute to aggregate traffic load, creating a dire need for…

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…

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…
