Heavy Networking 583: How Salesforce Evolved Its Branch Network With Prisma SD-WAN (Sponsored)

On today's Heavy Networking, sponsored by Palo Alto Networks, we hear from Salesforce about the evolution of its branch network to SD-WAN. Salesforce was able to trade MPLS for Internet broadband, get more bandwidth for less money, employ application-based steering and policy enforcement, and more. Our guests are Georgi Stoev, Sr. Network Architect at Salesforce; and Kumar Ramachandran, Senior Vice President at Palo Alto Networks.

Don’t OutSMART Your Goals

290C1DEE-0D66-432D-839A-C3C4B79B5F6D

I read a piece on LifeHacker yesterday that made me shake my head a bit. I’m sure the title SMART Goals Are Overrated was designed to get people to click on it, so from that perspective it succeeded. Wading into the discourse there was an outline of how SMART goals were originally designed for managers to give tasks to employees and how SMART doesn’t fit every goal you might want to set, especially personal aspirational ones. Since I have a lot of experience with using SMART goals both for myself and for others I wanted to give some perspective on why SMART may not be the best way to go for everything but you’re a fool if you don’t at least use it as a measuring tool.

SMRT, Eh?

As a recap, SMART is an acronym for the five key things you need to apply to your goal:

  • S – Specific (what are you going to do)
  • M – Measurable (how will you know when you’ve succeeded)
  • A – Attainable or Assignable (can you or the person you’ve selected do this thing)
  • R – Relevant or Relatable (is this goal appropriate for me or for the person doing it)
  • T Continue reading

Observe & Troubleshoot Your Kubernetes Environments with Dynamic Service Graph

Kubernetes workloads are highly dynamic, ephemeral, and are deployed on a distributed and agile infrastructure. Application developers, DevOps teams, and site reliability engineers (SREs) often require better visibility of their different microservices, what their dependencies are, how they are interconnected, and which other clients and applications access them. This makes Kubernetes observability challenges unique. While Kubernetes helps to meet the needs of deploying and managing distributed applications, its observability challenges require a Kubernetes-native approach.

Traditional monitoring and observability solutions create data silos by collecting data at different levels (e.g. infrastructure, cluster, and application levels), or from a large number of ephemeral objects that generate data across a distributed environment. Traditional monitoring and observability solutions then stitch this data together to provide a near real-time snapshot view. This approach is not scalable given the high volume of granular data generated at each level, as well as Kubernetes’ distributed nature. It also starts to become expensive and budget unfriendly to run traditional monitoring solutions, as they require higher resource consumption (high-performance memory, more compute, and higher bandwidth).

In contrast, a Kubernetes-native observability solution can visualize all information with all relationship context intact and provide a high-fidelity view of the environment. This Continue reading

Cloudflare TV: Doing it Live, 1,000 Times and Counting

Cloudflare TV: Doing it Live, 1,000 Times and Counting
Cloudflare TV: Doing it Live, 1,000 Times and Counting

Last week, Cloudflare TV celebrated its first anniversary the only way it knows how: with a broadcast brimming with live programming spanning everything from the keynotes of Cloudflare Connect, to a day-long virtual career fair, to our flagship game show Silicon Valley Squares.

When our co-founder and CEO Matthew Prince introduced Cloudflare TV to the world last year, he described it as a platform for experimentation. By empowering Cloudflare employees to try whatever they could think up on air — bound only by restraints of common sense — we hoped to unlock aspects of our team’s talent and creativity that otherwise might go untapped in the midst of the pandemic.

The results, as they say, have been extraordinary.

Since launching in June 2020, Cloudflare TV has featured over 1,000 original live episodes covering an incredible array of topics: technical deep dives and tutorials like Hardware at Cloudflare, Leveling up Web Performance with HTTP/3, and Hacker Time. Security expertise from top CISOs and compliance experts. In-depth policy discussions. And of course, updates on Cloudflare’s products with weekly episodes of Latest from Product and Engineering, Estas Semanas en Cloudflare en Español, and launch-day introductions to Magic WAN Continue reading

Review: Logitech Ergo K860 Ergonomic Keyboard

As part of an ongoing effort to refine my work environment, several months ago I switched to a Logitech Ergo K860 ergonomic keyboard. While I’m not a “keyboard snob,” I am somewhat particular about the feel of my keyboard, so I wasn’t sure how I would like the K860. In this post, I’ll provide my feedback, and provide some information on how well the keyboard works with both Linux and macOS.

Setup

Setting up the K860 is remarkably easy. The first system I tried to pair it with was an older Mac Pro workstation, and apparently the Bluetooth hardware on that particular workstation wasn’t new enough to support the K860 (Logitech indicates that Bluetooth 5.0 is needed; more on that in a moment). Instead, I popped in the USB-A wireless receiver, and was up and running with the K860 less than a minute later. This was using macOS, but the Mac Pro also dual-booted Linux, so I rebooted into Linux and found that the K860 with the Logitech-supplied USB receiver continued to work without any issues.

Linux, macOS, and Dual Boot Support

The key takeaway regarding Linux is this: if you’re interested in getting the K860 for use with Continue reading

Checking Linux system performance with sar

Sar is a system utility that gives us many ways to examine performance on a Linux system. It provides details on all aspects of system performance including system load, CPU usage, memory use, paging, swapping, disk usage, device load, network activity, etc.The name "sar" stands for "system activity report," and it can display current performance, provide reports that are based on log files stored in your system's /var/log/sa (or /var/log/sysstat) folder, or be set up to automatically produce daily reports. It's part of sysstat – a collection of system performance monitoring tools.To check if sar is available on your system, run a command like this:To read this article in full, please click here

Sparking the next cycle of IT spending

Who, in the entire IT space, wouldn’t like to see an uptick in tech spending?  Enterprises would see new purchases easier to make, vendors would make more money, and technologists in general would have a new sense of excitement and mission.  It seems like we’ve been stuck in a do-more-for-less rut, but the past offers us some evidence of how we could get out of it.If you were to plot of the growth in enterprise IT spending versus GDP growth for the US over the entire life of information technology, you’d see not a hockey stick but a series of peaks and valleys.  You would see that there are three clear periods or cycles where IT spending has significantly outstripped GDP growth, and that we’ve been in a trough ever since the last one ended in about 2000.  We’ve never had two decades pass without another cycle, so what’s wrong?  Answer: Nothing’s driving one now.To read this article in full, please click here

Announcing WARP for Linux and Proxy Mode

Announcing WARP for Linux and Proxy Mode
Announcing WARP for Linux and Proxy Mode

Last October we released WARP for Desktop, bringing a safer and faster way to use the Internet to billions of devices for free. At the same time, we gave our enterprise customers the ability to use WARP with Cloudflare for Teams. By routing all an enterprise's traffic from devices anywhere on the planet through WARP, we’ve been able to seamlessly power advanced capabilities such as Secure Web Gateway and Browser Isolation and, in the future, our Data Loss Prevention platforms.

Today, we are excited to announce Cloudflare WARP for Linux and, across all desktop platforms, the ability to use WARP with single applications instead of your entire device.

What is WARP?

WARP was built on the philosophy that even people who don’t know what “VPN” stands for should be able to still easily get the protection a VPN offers. It was also built for those of us who are unfortunately all too familiar with traditional corporate VPNs, and need an innovative, seamless solution to meet the challenges of an always-connected world.

Enter our own WireGuard implementation called BoringTun.

The WARP application uses BoringTun to encrypt traffic from your device and send it directly to Cloudflare’s edge, ensuring that no Continue reading
