Virtualization & Clouds – Are they related?

Frequently, I am asked about the relationship between Virtualization and Clouds. In one word, the answer is “yes”, they are related. They are symbiotic cousins. They can exist separately, but together place greater demands on re-designing networks.Virtualization technologies from VMWare, Citrix and Microsoft have created exponential server and network increase. A direct consequence of virtual…

Citrix and Arista – Two Pioneers Partner in Cloud Networking

Today’s Datacenters are still separated distinctly by OSI stack layers. Layer 2/3/4 switching are typically implemented by 1/10GE switches and application delivery functions such as L4-L7 server load balancing are deployed as appliance functions largely as two ships in the night. In a cloud environment, a more “in-band” network deployment model, one that is highly…

Does Latency Matter in Cloud Networking?

Cloud Networking has arrived upon us. Take server density on a scale never seen before plus compute demanding application workloads and you get a class of non-blocking cloud networking that is more aware of dynamic application flows than vanilla packet switching. A key design criterion here is Latency. Of course there are differing views on…

Which Technology Will Prevail for Cloud Networking?

As we enter this new era of dense servers and multi-core cloud computing, one must pay closer attention to the choice of the right cloud networking technology for seamless compute, network and storage access. I find myself in the midst of “Ethernot vs. Ethernet” choices. Three candidates present themselves as viable options: 10 Gigabit Ethernet,…

How Robust is your cloud network?

The IT industry has touted networking OS advantages for many generations. Cisco was the pioneer and leader in the 1990s with Cisco IOS, rich in features, albeit highly monolithic. In the second decade, both Juniper and Cisco developed targeted service provider-class software, with more modularity with JUNOS and IOS-XR. As we enter the third decade…

Cloud Networking Reflections 100 Days Later

It has been 100+ days since Arista Networks formally unveiled our new name, Cloud Networking mission and our much talked about leadership team. What is clear is more has been achieved in 100 days of Cloud Networking than is possible in 100 weeks. This is obviously the exponential power of modern applications, forums, groups, analysts,…

Evolutionary Designs for Cloud Networking

As 2009 begins, I have been thinking of how stale and stagnant the networking designs have been for the past decade, based on the classic three-layer of topology of core, distribution/aggregation and access. However, I do sense an architectural shift in the datacenter for cloud container environments changing the traditional constructs. Guiding this new cloud…

My Next Gig

It is truly my pleasure and honor to join Arista Networks as the President and CEO of the company. I have known founders, Andy Bechtolsheim and David Cheriton for a decade and worked with them closely during their Granite/Cisco days. To me, Arista is a symbol of an exciting, innovative silicon valley start-up company at…
