Solo.io: Istio Is Winning the Service Mesh War

The open source Istio has emerged as the “dominant” service mesh to manage microservices and Kubernetes environments, solo.io executives say. Gloo Edge 2.0, to be released in beta in the middle of the year is the “first and the only” Istio-native API gateway with all of Istio’s native functionality, Posta said. The ingress controller will integrate #SoloCon2021 https://t.co/VKAxWqk5KJ is fully committed to Istio. We see it as the dominant service mesh—it’s the one that’s most deployed to production and the most mature. #Gloo @soloio_inc #sponsored March 24, 2021 Solo.io’s proclamation also coincides with a number of new improvements for solo.io’s Gloo Edge platforms announced the new capabilities feature, among other things, an even tighter integration between #SoloCon2021 Continue reading

Sarantaporo.gr Community Network: Tending to Our Communities’ Needs with Care and Flexibility

At the beginning of May 2020, the Sarantaporo.gr community network team was approached by the Mayor of Elassona, a municipality in the Thessaly region in central Greece. He was asking for help with a very common problem that villages in our municipality face: lack of access to Internet connectivity. “Sykea” or “Sykia” is an isolated […]

Free Networking ArubaOS-CX Lab Image From Aruba Networks

This is a continuation of my post documenting hassle-free, virtualized network operating system images you can download for labbing and learning.

Aruba Networks (HPE) ArubaOS-CX

What is it?

While you probably think of wireless networking first when Aruba Networks comes up, ArubaOS-CX is a ground-up network operating system for switches built by the former HPE ProCurve team, if memory serves me correctly. Aruba has been a part of HPE for some time, and the networking folks within HPE fall under the Aruba hierarchy as I understand it.

I wrote an overview of ArubaOS-CX as part of a series on the Aruba 8400 switch launch back in October 2017.

Aruba offers a virtual version of ArubaOS-CX delivered as an OVA. You can use the OVA as-is, or extract the OVA tarball to get to the vmdk and convert the vmdk to a qcow2 image, all depending on what your hypervisor needs.

How do I obtain the image?

  1. Create an Aruba Support Portal account & log in via https://asp.arubanetworks.com/.
  2. Head to Software and Documents, currently https://asp.arubanetworks.com/downloads.
  3. In the left pane, filter on…
    1. File type: Software
    2. Product: Aruba Switches
    3. File Category: OVA
  4. Sort by: Version New To Old
  5. That Continue reading

Tom’s Corner and Turning Another Corner

Thanks to everyone that popped in for Tom’s Virtual Corner at Cisco Live Global 2021. It was a great time filled with chats about nothing in particular, crazy stories about unimportant things, and even the occasional funny picture. It was just was Tom’s Corner has always been. A way for the community to come together and be around each other in a relaxing and low-key environment. Maybe we couldn’t meet in person but we got together when we needed it the most.

There was also something else that Tom’s Corner has represented for me for the last year that I didn’t even catch until it was pointed out to me by my wonderful wife Kristin (@MrsNetwrkingNerd). Tom’s Corner was the start of something that made me feel better about everything.

Get On Up and Move

After Tom’s Virtual Corner in 2020, I was energized. I needed to get up and get things done after sitting in a chair for hours talking to all my absent friends and getting the energy I needed to feel after months of being locked away during a pandemic. I felt on top of the world for the first time in quite a while. Continue reading

Durable Objects, now in Open Beta

Durable Objects, now in Open Beta
Durable Objects, now in Open Beta

Back in September, we announced Durable Objects - a new paradigm for stateful serverless.

Since then, we’ve seen incredible demand and countless unlocked opportunities on our platform. We’ve watched large enterprises build applications from complex API features to real-time games in a matter of days from inception to launch. We’ve heard from developers that Durable Objects lets them spend time they used to waste configuring and deploying databases on building features for their apps. More than anything, we’ve heard that you want to start building with Durable Objects now.

As of today, Durable Objects beta access is available to anyone with a Cloudflare Workers® subscription - you can enable them now in the dashboard by navigating to “Workers” and then “Durable Objects”. You can also upgrade to the latest version of Wrangler to deploy Durable Objects!

Durable Objects are still in beta and are being made available to you for testing purposes. Storage is capped per-account at 10 GB of data, and there is no associated SLA for Object availability or durability.

Enable beta access now »

What are Durable Objects?

Durable Objects provide two things: coordination across multiple Workers and strongly consistent edge storage.

Normally Cloudflare’s network executes a Continue reading

Intermittent Terraform Authentication Failure Using AWS Provider in a Vagrant VM

TL&DR: Client clock skew could result in AWS authentication failure when running terraform apply

When I wanted to compare AWS and Azure orchestration speeds I encountered a crazy Terraform error message when running terraform apply:

module.network.aws_vpc.My_VPC: Creating...

Error: Error creating VPC: AuthFailure: 
AWS was not able to validate the provided access credentials
	status code: 401, request id: ...

Obviously I did all the usual stuff before googling for a solution:

DNS at IETF 110

The amount of activity in the DNS in the IETF seems to be growing every meeting. I thought that the best way to illustrate to considerably body of DNS working being undertaken at the IETF these days would be to take a snapshot of DNS activity that was reported to the DNS-related Working Group meetings at IETF 110.

Free Networking Lab Images From Arista, Cisco, nVidia (Cumulus)

Here’s my current list of no cost, minimal headache, easily obtainable networking images that work in a virtual lab environment such as EVE-NG or GNS3. My goal is to clearly document what these images are and how to obtain them, as this data is less obvious than I’d like.

I missed some. Probably a bunch. Let me know on the Packet Pushers Slack channel or Twitter DM, and I’ll do additional posts or update this list over time. Make sure your recommendations are for images which are freely available from the vendor for lab use with no licensing requirements or other strings attached. Use those same channels if you just want to tell me I’m wrong about whatever you come across in this post that’s…you know…wrong. I’m all about fixing the wrong stuff.

The list is vendor-neutral, sorted alphabetically. I have no personal allegiance to any of these operating systems. I’ve worked with both EOS and NX-OS in production environments. JUNOS, too, although I don’t have a Juniper virtual device on this list currently. I haven’t worked with Cumulus in production, although it’s been a passive interest for a while now.

Remember–configuration is the boring part. Select a NOS Continue reading

A Birthday Challenge as Docker Turns 8

Time flies. Eight years ago Docker was introduced to the world and forever changed the way applications are developed. We have enjoyed watching developers from all walks of life and from every corner of the globe bring their ideas to life using our technology. 

As is our tradition in the Docker community, and as announced during our last Community All-Hands, we are celebrating Docker’s big day with a birthday challenge where Docker users are encouraged to learn some of our Docker Captain’s favorite tips + tricks by completing 8 hands-on interactive exercises. Unlike last year’s challenge, this year as you complete an exercise you not only earn badges but you also earn points based on speed and accuracy which will be displayed on a leaderboard organised by individual score, country score and Captain score.

The challenge is on for the next month and we will announce the winners and award special prizes to the top three individual scores. 

So let’s celebrate 8 years of Docker and let the challenge begin!

Intel’s $20 billion bet on advanced fabrication

No one ever said Pat Gelsinger was timid. A month into his stint as Intel’s CEO, he has announced an ambitious plan to drive ahead with Intel’s chip-manufacturing efforts rather than give up on it.Naysayers and pundits had been saying Intel should dump its fabrication business, similar to what AMD did more than a decade ago when it spun out its fabs into what became GlobalFoundries. Intel’s fabs had fallen behind the bleeding edge, and while the TSMC foundry was making 7nm chips for AMD, Intel was struggling to get to 10nm.Well bleep that, said Gelsinger (OK, maybe not). Rather than spin off the foundry business, Intel is setting it up as a separate unit within the company called Intel Foundry Services with its own profit and loss statements like the other Intel divisions. So in addition to making Intel chips, Intel Foundry Services will make chips for other semiconductor companies.To read this article in full, please click here

Arm’s v9 Architecture Explains Why Nvidia Needs To Buy It

Many of us have been wracking our brains why Nvidia would spend a fortune – a whopping $40 billion – to acquire Arm Holdings, a chip architecture licensing company that generates on the order of $2 billion in sales – since the deal was rumored back in July 2020. …
