Good to Great: Hallmarks of High-Tech Leadership

You are probably expecting me to write another monthly blog on exciting innovative technology. Today I digress and reflect on recent awards and accolades Arista has received and how we got here. At Arista, we have worked very hard to become a great company. Building a good company takes constant hard work and heavy lifting. Making a great company is an even harder work-in-progress, demanding tenacity, especially in high technology, where disruptions are daunting and challenges are frequent.

Arista Any Cloud Networking – Our Next Frontier

The modern cloud networking world is vastly different from traditional enterprise IT, and the gap is getting wider everyday. How does one truly scale across millions of machines and workloads globally? A decade ago, Arista pioneered the new software driven networking era and the same challenges now exist not only across the LAN intra-datacenters but also inter-datacenters via wide area networks (WANS). Although we have never promoted “SD-LAN” nor understood the “SD-WAN” hype, Arista has redefined software driven networking and pioneered the convergence between LANs and WANS.

Evolution from PINs to PICs Cloud Networking

Networking is simply so cool again after decades of static and stagnant silo designs. The rapid acceptance of universal cloud spine across a variety of clouds and industry verticals is a testament to just how critical of a problem this is to IT. By adopting a clean sheet of modern methodologies and code with a programmable state-based foundation, we are embarking on the next frontier.

Scaling Cloud Networking Up and Out

The broad adoption of Arista’s 100G spines and the enthusiastic acceptance of Arista’s R series exemplifies the demands of cloud networking. Leveraging the programmable, state-based EOS software foundation and 12 different merchant silicon chipsets, Arista has transformed the datacenter market over the past decade. Today we are introducing the next frontier in router migration for the decade ahead. Arista has been in the forefront of industry firsts with state driven programmable EOS and CloudVision, based on network wide cloud-class control and management.

Managing the Cloud Network: CPM or APM?

We all know the future of enterprises is in flux with the consolidation or demise of Avaya/Nortel, Brocade/Foundry, Force 10, H3C and BNT assets. This speaks to the major trend of enterprise applications migrating to the cloud, any cloud be it public, private or hybrid. As this rapid transition prevails with efficiencies and scale, traditional applications and... Read more →

The Catalyst for Cloud Networking with Containerization

Today's applications are connected both to users and other applications, increasing traffic and profoundly affecting performance.

The Catalyst for Cloud Networking with Containerization

Today’s applications are connected both to users and other applications, increasing traffic and profoundly affecting performance. Recently, there has been much discussion around the Application Performance Management (APM) category. This got me thinking about new cloud migration versus legacy application tools. Is the industry being myopic and dealing with silos?

Tap DANZing for Visible Cloud Networking

Networking is running blind. It is akin to driving a car in the fog at night without street lights, signs or a navigation system. Simply put, it’s a scary visibility problem, and it impacts the security and availability of the network. When coupled with massive shifts to virtualization, containerization, cloud-native applications and unstructured data, the insatiable telemetry demand is exponential. Every architect is looking for modern analytical methods of networking to gain visibility for millions of devices, data or events efficiently and consistently.

The New Tech Economy in Cloud Networking

In the 1950s, the introduction of jet engine technology revolutionized air transport, allowing for the transport of goods and people across oceans far more quickly than with traditional propeller-based aircraft. A new airline industry on a global basis arose from the jet engine revolution.

Beyond Scale to Flexible Cloud Networking

In the early 2000’s a new generation of smartphones revolutionized the cell phone industry, eliminating the market for “flip phones,” introducing new tools and completely redefining “phones” to universal internet devices. New companies rose and old ones adapted or failed. In 2015, a new generation of electric cars (Tesla being the most well-known), were introduced and drove the next wave of technology transitions, replacing gas-guzzling cars in many households. Consumers and traditional car companies worldwide are now embracing the new technology.

The State of Telemetry in Cloud Networking

The hype of Software Defined Networking (SDN) and its associated analytics is alive and well. Many are advocating changing the way monitoring is done. Are we ready for re-invention? How should one react? Or should we plan better? What happens to decades of network management that are habitual? Legacy vendors understandably feel defensive, declaring new marketing visions and paradigms, while new and innovative vendors are delivering real functionality that meets customer needs! At Arista, we saw the emergence of a need for better visibility and monitoring in 2010, with exponential growth of workloads in the cloud to bring together many forms of telemetry. We have been deploying Arista Tracers with EOS ^® for over five years, and now we are entering the next generation of real-time telemetry.
