Open Cloud Networking-Redefined

Networking vendors have long touted distinct routers and switches with different LAN/WAN interfaces for different customer use cases. After three decades of evolution, Ethernet now truly addresses all aspects of the present state and the next generation of networking, making it possible to support these previously separate use cases from a single common platform, which flexibly incorporates new capabilities in an open, standards-based approach. Arista, together with an ecosystem of partners including Broadcom and Cloud Titan customers, has a history of collaborating in many industry forums to define these new networking capabilities, including OCP, 25/50G and COBO, while driving next generation optics such as OSFP and QSFP-DD.

Tech Time is Real Time

Silicon Valley is both an addiction and passion where entrepreneurs seek the realm of the impossible. Real-time language translation, fraud detection, and autonomous vehicle control are being addressed through the use of neural network models, detecting patterns and behaviors across massive amounts of structured and unstructured data. Indeed, change is not only a constant progression in Silicon Valley, it is a continuum in time. Every piece of traditional technology has to imminently become smarter, challenged or be eliminated. While this transformation is especially true for entrepreneurs, invention is not limited to start-ups. I have witnessed several waves of evolution and revolution during my journey in Silicon Valley in both high-tech and networking.

Cognitive Campus – Next Frontier

Arista’s focus on disruption, with datacenters and routing, transforming siloed places in the network to seamless Places In the Cloud (PICs) has been well appreciated by our customers. Our cloud networking decade has been achieved by upholding these cloud principles and I believe these trends will influence cognitive campus PICs. Legacy campus networks suffer from a similar complexity of too many layers, boxes, cables, operating systems, proprietary features and network management choices. A change is very much needed and welcome in the 2020 era.

Rethinking Security in Cloud Networking

Every CXO worries about security because the perimeter is changing; in fact, there are no walls for protection. The lines between cloud, workloads, applications, enterprise networks and hosts are blurring and the challenges are getting exponentially greater. The true security architect must rapidly address the reality of a more holistic network-wide security strategy. It must be one that goes beyond the cyber threat of the day to address the risk, scale and mitigation of persistent security issues. The state of cyber security needs urgent resolution because:

The Pursuit of Inspired Leadership

At Arista Networks, great technology and leadership inspires us to innovate and continue our mission to reinvent. It’s an ongoing journey to create the right leaders and disruptive technology for market transitions and Arista’s evolution. Today I digress a bit, as I was reading a 2017 Harvard Business Review article on the four key traits identified for successful CEOs. So much of it resonated with me with respect to the Arista way and our company culture. Let’s review how these traits apply to a fast-paced technology company like Arista.

Universal Cloud Networking with Arista 7170

There is a shift happening in the world of Artificial Intelligence requiring a new breed of servers, storage and cloud networks. Artificial intelligence applications for patterns, photos and speech recognition have driven a processor evolution from CPUs to NPUs to now, GPUs. Networking is witnessing a parallel evolution and pushing the scale of shuttling massive data between machines. It creates an ever-increasing need for control over the way networks are rebuilt. Building these networks requires both, programmable paths to drive intelligence and uncompromised performance. Doing both hasn’t been easy until now.

Unveiling Cognitive Campus Networking

At Arista Networks, the status quo inspires us to innovate and continue our mission to reinvent the network – from ­­cloud to client. Today, we’re continuing that journey – into the campus network. Let’s face it; the legacy three-tier architecture of access-aggregation-core is wasteful and oversubscribed – creating a perfect storm for market transitions and Arista innovation.

CloudVision: A Cognitive Management Plane

The last 40 years have seen tremendous growth and progress in the data networking industry. Ethernet, IP, MPLS, GRE, IPsec, MACsec, and VXLAN enable operators to build secure, multiservice, high-performance data planes that interoperate across multiple vendors, multiple operators, and multiple administrative domains. Likewise, BGP, OSPF, IS-IS, LDP, RSVP, BFD, LACP, L3VPN, VPLS, and EVPN enable operators to build scalable multi-vendor control planes that federate across organizational boundaries, supporting mission-critical networks with global reach.

Cognitive Cloud Networking with Arista X3 Series

At Arista we have always embraced open networking trends by designing our hardware and software to be as programmable as possible, driving the use of merchant silicon and diversity for the broader industry. It has allowed our customers to select their favorite silicon architectures for the switch pipeline and choose the suite of software and hardware they want to form their cognitive network systems. 

The Future of Cognitive Cloud Networking

Artificial Intelligence, machine and deep learning have to be among the most popular tech-words of the past few years, and I was hoping that I wouldn’t get swept away by it. But when I heard a panel on this topic at our customer event this month on the state of AI networks, I found it incredibly fascinating and it piqued my curiosity! Let me start with a note of disclaimer for readers who are expecting a deep tutorial from me. There is a vast amount of research behind models and algorithms on this topic that I will not even attempt to cover. Instead I will try to share some thoughts on the practical relevance of this promising field.

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.

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? Wouldn’t it be amazing if...
