This week's Network Break podcast covers a startup backed by ex-Cisco CEO John Chambers, US federal agencies wanting service providers to get serious about BGP security, SASE growing 30% in a quarter, a thriving floppy disk business, and more IT news.

Today on the Tech Bytes podcast we talk with sponsor Palo Alto Networks about the latest AI Ops features for SD-WAN. AI Ops analyzes network data and then recommends fixes for probems, a capability that's becoming increasingly necessary as network complexity grows to encompass underlays, overlays, on and off-prem cloud destinations, remote working, and more.

netlab release 1.3 introduced support for VXLAN transport with static ingress replication. Time to check how easy it is to replace a VLAN trunk with VXLAN transport. We’ll use the lab topology from the VLAN trunking example, replace the VLAN trunk between S1 and S2 with an IP underlay network, and transport Ethernet frames across that network with VXLAN.

Hello my friend,
As mentioned in the previous blogpost, we continue looking into Kubernetes. In the previous blogpost we have built a simple cluster consisting of one control plane node, which is the one ruling the cluster, and two worker nodes, which are the ones hosting the customers’ workloads. Today we will add a few more nodes, both workers and control plane, to the cluster to convert it into a high available one.

We absolutely are. One of the important things we have figured out is that automation is for sure the cross-platform technology. Therefore, whatever area you are coming from or heading two (networking, system administration, or cloud engineering), knowledge of automation frameworks and components, such as Ansible, Bash, Python, YAML, JSON, REST API, GRPC/GNMI is very beneficial and, in fact, is almost mandatory these days.
And in our Network Automation Trainings we have put it together in Continue reading
Cloudflare launched on September 27, 2010. This week we'll celebrate our 12th birthday. As has become our tradition, we'll be announcing a series of products that we think of as our gifts back to the Internet. In previous years, these have included products and initiatives like Universal SSL, Cloudflare Workers, our Zero Markup Registrar, the Bandwidth Alliance, and R2 — our zero egress fee object store — which went GA last week.
We're really excited for what we'll be announcing this year and hope to surprise and delight all of you over the course of the week with the products and features we believe live up to our mission of helping build a better Internet.
While this will be our 12th Birthday Week of product announcements, for the last two years, as the cofounders of the company, we've also taken this time as an opportunity to write a letter publicly reflecting on the previous year and what's on our minds as we go into the year ahead.
Since our last birthday, it's been a tale of two halves of a very different year. At the end of 2021 and into the first two months Continue reading
Charity Majors published another masterpiece: The Hierarchy Is Bullshit (And Bad For Business).
I doubt that anyone who would need this particular bit of advice would read or follow it, but (as they say) hope springs eternal.

Encrypted traffic poses a problem for enterprise policy enforcement. On today's Heavy Networking, we explore the notion of zero knowledge middleboxes, which use a variety of techniques to allow firewalls or other middleboxes to enforce policy without the need for decryption. Our guest is Dr. Paul Grubbs, whose research into zero knowledge middleboxes prompted this episode.

Welcome to Technology Short Take #160! This time around, my list of links and articles is a tad skewed toward cloud computing/cloud management, but I’ve still managed to pull together some links on other topics that readers will hopefully find useful. For example, did you know about the secret macOS network quality tool? You didn’t? Lucky for you there’s a link to an article about it below. Read on to get all the details!
Back in 2019, we worked on a chart for Cloudflare’s IPO S-1 document that showed major releases since Cloudflare was launched in 2010. Here’s that chart:
Of course, that chart doesn’t show everything we’ve shipped, but the curve demonstrates a truth about a growing company: we keep shipping more and more products and services. Some of those things start with a beta, sometimes open and sometimes private. But all of them become generally available after the beta period.
Back in, say, 2014, we only had a few major releases per year. But as the years have progressed and the company has grown we have constant updates, releases and changes. This year a confluence of products becoming generally available in September meant it made sense to wrap them all up into GA Week.
GA Week has now finished, and the team is working to put the finishing touches on Birthday Week (coming this Sunday!), but here’s a recap of everything that we launched this week.
| What launched | Summary | Available for? |
