Streaming Telemetry With Avi Freedman on Software Gone Wild

Ivan Pepelnjak was a delegate at Networking Field Day in September 2017 and was impressed with the presentations from Kentik’s CEO and Co-founder, Avi Freedman. Ivan, his colleagues, and Avi Freedman discussed streaming telemetry on the podcast, Software Gone Wild. Check out this episode to hear what they had to say!

Cloud Networking Architectures

In this post from Ivan Pepelnjak, he breaks down one of the realities of running virtual machines on cloud infrastructure. These VMs still look for an Ethernet interface. For many enterprise-focused platforms, this means simply emulating a physical Ethernet cable. This allows admins to not have to relearn their networking stack. But the cloud providers implemented virtual networking that can scale beyond a few hundred hosts, using smart NICs. At Cloud Field Day, Pensando showed how they are trying to bring that kind of scale to the enterprise with their own smart NIC. Ivan looks at their solution and how it can fit into the enterprise world.

My Journey Into Cloud Networking

Nicola Arnoldi shares his journey into cloud networking in this blog post. For Nicola, this isn’t a hard break into a brave new networking world, rather an extension of all that has come before. This started during network disaggregation planning while working at a large telco, but really accelerated as Nicola started getting comfortable with automation. He sees the hardest part for a lot of network engineers on this journey is being able to trust a lot of the cloud networking abstractions, rather than worrying about all the underlying specifics. We’re glad that Nicola’s conversations with Ivan Pepelnjak at Tech Field Day Extra at Cisco Live Europe a few years ago was considered a significant milestone on his journey with cloud networking.

Worth Reading: Understanding Scale Computing HC3 Edge Fabric

Ivan Pepelnjak shares a great piece looking at Scale Computing HC3 Edge Fabric, something the company talked about during their recent Tech Field Day presentation. While Ivan doesn’t think its a once size fits all solution, he thinks it makes perfect sense in small environments.

How Do You Provision a 500-Switch Network in a Few Days?

One of the interesting aspects of a IT event the scale of Cisco Live is that it has its own unique set of IT challenges. During a behind the scenes tour during Tech Field Day Extra at Cisco Live US 2019, Ivan Pepelnjak got to ask how they created the network for the event in such a short amount of time. What he found was that provisioning a large campus network in a few days is easy and reliable as long as you do your homework and keep things as simple as possible.

Tech Field Day Extra @ CLEUR19 Recap

Cisco Live Europe is an event big enough that it’s tough to encapsulate in any one post. That’s why it’s great to have smaller, more focused looks, especially when it comes from Ivan Pepelnjak. He wrote up a posting looking at what he saw from Tech Field Day Extra at Cisco Live Europe. Cisco touched on automating Meraki deployments, new AWS-focus Cisco ACI features, HyperFlex updates, and more. Be sure to read Ivan’s thoughts on what he saw, and watch the presentation video for yourself.
