Enabling Network Applications with VMware, Microsoft and the Ecosystem

With the advent of the modern application era in data centers for applications such as business analytics and web services and the accompanying deployment of cloud computing environments, we see the arrival of a universal cloud network. The infrastructure requirements for modern data center applications are in fact quite different from those originally associated with…

The Software Choices for Cloud Networking

These days there is much discussion on “disaggregation” of switches or routers – the splitting of the hardware from the software, the control plane from the data plane. Should they be built with proprietary and monolithic decades-old software, such as the Cisco IOS or NXOS, or leverage a more open standards-based Linux OS, and be…

Shifting from Enterprise to Cloud with the Arista 7500E

The rapid adoption in data centers of virtualized servers powered by multicore CPUs, the deployment of petabytes of storage and the increasing use of Hadoop for data analytics has challenged the traditional data center network. The resultant mobile workloads and massive unstructured data sets shuffling from nearline storage to server clusters for data analytics are…

Bringing SDN to Reality

It is difficult to get one definition of SDN – interpretations vary. The purist would say it’s a separation of the data and control planes using a controller to communicate between the two. This was the original thesis of OpenFlow. Network virtualization, as driven by VMware/Nicira and Arista, has emerged as one of the most…

Celebrating One Million Ports of Software Defined Cloud Networking and Introducing the Arista Data Analyzer (DANZ)

For the past 5 years, Arista has been setting the agenda for software defined cloud networking. We are not addressing the legacy enterprise market for general-purpose applications. Instead our innovative customers expect us to enable high performance transactions and analytics with cloud-scale, self-healing resilience, programmability, precision data analysis and network wide virtualization, while radically reducing…

Software-Defined Cloud Networking Reflections

Every year I like to reflect upon my beginning of year predictions and compare them with the reality of what actually occurred. Once again that time has come, so let’s take a walk together down memory lane and see how I did. I also look forward to exciting outcomes for the industry in 2013. What…

SDN is about Programmable Networking

The hype of Software Defined Networking (SDN) is alive and well. Many are advocating changing the classical IP model and moving to a network where a centralized controller makes all forwarding decisions by pushing forwarding states directly to switches. Is the Internet ready for re-invention? How should one react? What happens to the decades of…

The Many Facets of Software-Defined Switching

In recent times many Software Defined Networking (SDN) advocates are seeking to establish a new paradigm of networking that better optimizes for applications in place of establishing simple connectivity. This software may be embedded in management controllers or protocols depending on the application. What is clear is developing and deploying modern software for next generation…

The Power of Programmable Cloud Networking

For past few decades, our internetworks have been built and have operated in a decentralized manner, thus avoiding the pitfalls of a single point of failure. This is a design principle that comes from the original ARPANET, which was architected to survive the ultimate failure mode – a nuclear attack. Fundamental to these interconnected networks…
