SD-WAN Helps Medical Imaging Company Get The Picture Faster
Today’s Tech Bytes podcast features an interview with Duleep Wikramanayake, Chief Information Officer, SimonMed Imaging.
SimonMed is a provider of medical imaging and radiology services. The company sends massive 2D and 3D medical images across the country. The company needed a faster, more efficient WAN to better serve radiologists and patients.
With approximately 150 locations, the company manages more than 300 site-to-site VPNs and moves approximately 850Gbytes of image data per day. The company turned to Silver Peak SD-WAN to speed up file transfers from minutes to seconds, improve performance of other business-critical applications such as voice, and begin a migration off expensive MPLS circuits.

Securing Remote Work For 2021 And Beyond With Zscaler (Sponsored)
In the early months of 2020, many organizations were on emergency footing as they transitioned to support remote workers at scale. Now that we’ve moved beyond the “just make it work” phase, organizations are thinking long term about the future of a highly distributed workforce. It’s time to have a strategy to make remote work for efficient, secure, and sustainable.
On today’s Tech Bytes podcast, sponsored by Zscaler, we explore securing a distributed workforce for 2021 and further, the role of Zero Trust Access, and more.
Our guest is Pam Kubiatowski, Sr. Director of Transformation Strategy at Zscaler.
* Developing a distributed work strategy for 2021 and beyond
* The attributes of Zero Trust Access
* How Zscaler secures access to applications, not networks
* The emerging hybrid model of remote access

BiB099: Isovalent Brings You Cilium Enterprise
The following is a transcript of the audio file you can listen to in the player above.
Welcome to Briefings In Brief, an audio digest of IT news and information from the Packet Pushers, including vendor briefings, industry research, and commentary.
I’m Ethan Banks, it’s December 8th, 2020, and here’s what’s happening. I had a briefing with Isovalent on November 12th.
Who Is Isovalent?
Isovalent is the commercial offshoot of cloud-native networking project Cilium. Got it? No? Never heard of Cilium? Fair enough. You might not have if you don’t have much reason to pay attention to the Kubernetes and cloud-native networking world.
Cilium is an open source networking project with many capabilities. I’ll quote from one of the cilium.io project pages. “Cilium’s control and data plane has been built from the ground up for large-scale and highly dynamic cloud native environments where 100s and even 1000s of containers are created and destroyed within seconds. Cilium’s control plane is highly optimized, running in Kubernetes clusters of up to 5K nodes and 100K pods. Cilium’s data plane uses eBPF for efficient load-balancing and incremental updates, avoiding the pitfalls of large iptables rulesets. Cilium is fully IPv6-aware.”
Wait a minute. In that quote, they said “eBPF” not BGP or EVPN in case that’s what your brain heard. So what is eBPF? That’s extended Berkeley Packet Filter. From eBPF.io, eBPF is “eBPF is a revolutionary technology that can run sandboxed programs in the Linux kernel without changing kernel source code or loading kernel modules. By making the Linux kernel programmable, infrastructure software can leverage existing layers, making them more intelligent and feature-rich without continuing to add additional layers of complexity to the system.” That is, it’s a tool Cilium leverages, not a feature Cilium has. Cilium uses eBPF to make cloud-native networking with Kubernetes suck less.
Now I just threw a lot of tech at you, but in a nutshell, we’re talking about being able to do fancy packet processing in the Linux kernel and do it relatively efficiently. We’re not having to copy packets between kernel and user space, clobbering our throughput.
Cilium uses this capability to bring not only cloud-native networking connectivity, but also a bunch of other features. You can replace kube-proxy, a core Kubernetes component, with Cilium. In theory, you could leverage Cilium instead of using a sidecar proxy. Cilium can tell you what Kubernetes workload and pod is tied to a flow. Cilium offers Prometheus-friendly metrics via an add-on called Hubble. Observability. Hubble. See what they did there?
And the wonders of Cilium continue with security features and more.
So Back To Isovalent…
Remember that Isovalent is essentially a commercially supported flavor of Cilium, although it’s more than that. Isovalent is offering Cilium Enterprise, which adds more capability to the Cilium Community project. Is there enough “more” to make you want to invest in Cilium Enterprise? That will depend on your organizational needs, of course, but the differences are substantial enough to warrant investigation.
If you get what I’m saying here, Cilium Enterprise is not just the open source project with support from Isovalent bolted on. Cilium Enterprise is a distinct product of its own that Isovalent is offering. Isovalent.com’s product page has a comparison chart explaining how the community and enterprise editions of Cilium vary. The differences are many.
What Does Isovalent Do Next?
Isovalent is growing. They just landed a $29 million dollar round of funding, and they are hiring in their engineering, sales, and marketing departments according to their career page. They’ve got a compelling technical heritage with Cilium, and are solving interesting problem…
ThousandEyes Expands Visibility Into Modern App Architectures (Sponsored)
Our topic for this Tech Bytes episode is cloud visibility with sponsor ThousandEyes. The company is rolling out a host of new improvements to its platform including multi-service views, Internet and hybrid cloud visibility, SD-WAN monitoring, and more. The goal is to give you a more comprehensive view of the dependencies that make up today’s applications, services, and networks.
Our guests from ThousandEyes are Angelique Medina and Archana Kesavan.
* How multi-service views can stitch together dependencies
* Getting a better view of your SD-WAN underlay
* More extensive SaaS monitoring

Automating Troubleshooting With Riverbed (Sponsored)
Our story is this Day Two Cloud Tech Bytes episode is about the automation of troubleshooting. For a lot of network engineers, Wireshark and a laptop are the standard tools for diagnosing a problem. And while Wireshark and a laptop can be very useful, there are situations where they may not be enough.
The goal is to take advantage of machine learning to be able to react to network issues automatically. Riverbed is our sponsor for this conversation, and our guest is Chris Eckert, Technical Solutions Architect at Riverbed.
* Why packet capture and flow records are necessary elements for troubleshooting
* What and where to monitor
* How to transition from reactive responsive to an automated approach
* Building a machine learning baseline
* The importance of APIs for your monitoring and visibility tools
