Software-Defined Cloud Networking Reflections

Every year I like to reflect upon my beginning of year predictions versus the actual outcomes. Once again that time has come, so lets take a walk down memory lane and see how I fared. Prediction #1: The rise in server virtualization will drive network virtualization deployments. Evaluation #1: Half true. We began to see…

A New Cloud Network “Spline™” Is Born

The dramatic shift to East-West traffic patterns within the data center is creating excitement, new customer requirements and many new three-letter acronyms such as SDN, HDN (read ASICS) or ACI. Add the term “Fabric”, touted by many, and the confusion deepens with proprietary technology. Be it Q-Fabric, Fabric Controllers, ACI or Fabric Path, these are…

Redefining Cloud-Networking Resilience & Visibility

In modern two-tier leaf-spine cloud networks, the increasing dominance of east-west traffic patterns, accompanied by the sheer volume of traffic and the increase in data rates from 10G to 40G/100G are combining to make it challenging to predict and analyze performance issues proactively. The scale involved in connecting 100K+ physical servers, 1M+ Virtual Machines and…

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…
