NGINX Steps into the Service Mesh Fray Promising a Simpler Alternative

Earlier this month, NGINX NGINX Service Mesh (NSM), a free and open source service mesh that uses NGINX proxy, to power its data plane. While many service meshes are built from entirely open source components, NGINX Vice President of Marketing Aspen Mesh, the more advanced, Istio-based service mesh built by its now-parent company Service Mesh Interface (SMI) is not supported, but it is on the roadmap, and the NGINX Unit to “introduce something that’s a little bit different and more novel to advance the industry dialogue.” “We think there’s an option in the future to have a sidecar-less service mesh, where you’re not injecting sidecars in each service,” said Whitely. “Instead, you load your code, and you execute it, and the default runtime environment that’s executing your code has all the built-in proxying capabilities needed to handle east-west. It would take things down from a two container to one container kind of model.” Feature image by Unsplash.

What Is A Zero Trust Network Architecture

Every few years the industry takes a significant step towards a more holistic and capable security model. At the beginning, everything and everyone was trusted, and for good reason. You knew every operator and every machine that was connected to the network. But as networks have become ubiquitous, that level of trust is simply unreasonable. So we’ve built firewalls, and differing levels of inspection, but all of these tools still allow for some implicit level of trust between a machine and those machines closest to them. That is changing and that is what we’re here to talk about today. The newest trend in security is the concept of zero trust, and while it’s suffering the common plight of any new trend with multiple vendors trying to shape the definition, removing implicit trust in our networks is the next logical step towards a truly secure infrastructure.

Goldman Sachs to invest $500 million in data center development platform

The data center industry continues to grow. Amazon, Google, Equinix, Digital Reality Trust, and numerous other providers can't build their data centers fast enough, spurring investments in startups and a hefty amount of M&A activity. The sector was hot before the COVID-19 pandemic, and the crisis has only increased interest as companies accelerate their migrations to the cloud.Goldman Sachs is the latest to make a big play in the data center market. The firm's Merchant Banking Division is partnering with a management team led by Digital Reality co-founder and former chief investment officer Scott Peterson to form a new company, Global Compute Infrastructure LP.To read this article in full, please click here

IoT and AI boost Volvo Trucks vehicle connectivity

The vehicles manufactured by Volvo Trucks keep getting smarter.More than 350,000 Volvo rigs crossing North American highways each day are outfitted with IoT sensors that monitor conditions and send data for troubleshooting and analysis. Embedded telematics allow for over-the-air updates to engine software. The on-board technology, combined with a back-end analytics platform, enables Volvo Trucks to process millions of data records instantaneously. Using IoT and artificial intelligence, Volvo Trucks has been able to reduce diagnostic time by 70% and truck repair time by 25%. To read this article in full, please click here

Building Secure Layer-2 Data Center Fabric with Cisco Nexus Switches

One of my readers is designing a layer-2-only data center fabric (no SVI interfaces on switches) with stringent security requirements using Cisco Nexus switches, and he wondered whether a host connected to such a fabric could attack a switch, and whether it would be possible to reach the management network in that way.

Do you think it’s possible to reach the MANAGEMENT PLANE from the DATA PLANE? Is it valid to think that there is a potential attack vector that someone can compromise to source traffic from the front of the device (ASIC) through the PCI bus across the CPU to the across the PCI bus to the Platform Controller Hub through the I/O card to spew out the Management Port onto that out-of-band network?

My initial answer was “of course there’s always a conduit from the switching ASIC to the CPU, how would you handle STP/CDP/LLDP otherwise”. I also asked Lukas Krattiger for more details; here’s what he sent me:

DNS Trends

We're now using the Internet's address infrastructure in very different ways than the way we had envisaged in the 1980's. The Internet’s name infrastructure is subject to the same evolutionary pressures, and its these pressures I’d like to look at here. How is the DNS is responding?

OnVue – Get certified from your home

OnVue

One of the positive aspects of this difficult period, if I may say so, is the possibility of taking a Pearson Vue test online, called OnVue. Last Friday, October 23rd, I took a Cisco exam from home and I think it’s interesting to share with you the details of this experience. With OnVue – Get certified from your home! The registration for the exam The registration for the test is almost the same as for a Cisco test done in a Vue test center. Go to the website of Pearson…

Docker’s Next Chapter: Our First Year

2020 has been quite the year. Pandemic, lockdowns, virtual conferences and back-to-back Zoom meetings. Global economic pressures, confinement and webcams aside, we at Docker have been focused on delivering what we set out to do when we announced Docker’s Next Chapter: Advancing Developer Workflows for Modern Apps last November 2019. I wish to thank the Docker team for their “can do!” spirit and efforts throughout this unprecedented year, as well as our community, our Docker Captains, our ecosystem partners, and our customers for their non-stop enthusiasm and support. We could not have had the year we had without you.

This next chapter is being jointly written with you, the developer, as so much of our motivation and inspiration comes from your sharing with us how you’re using Docker. Consider the Washington University School of Medicine (WUSM): WUSM’s team of bioinformatics developers uses Docker to build pipelines – consisting of up to 25 Docker images in some cases – for analyzing the genome sequence data of cancer patients to inform diagnosis and treatments. Furthermore, they collaborate with each other internally and with other cancer research institutions by sharing their Docker images through Docker Hub. In the words of WUSM’s Dr. Continue reading

AMD Girds For Compute War With Xilinx Deal

The rumors were right, and AMD president and chief executive officer Lisa Su is indeed printing out a tower of stock to acquire FPGA maker Xilinx for what amounts to about $35 billion and, as it turns out, she is relinquishing her position as president to Victor Peng, chief executive at Xilinx, to close the deal. …

The History of Networking: John Chapman and Cable Networks

Before the large cable providers came on the scene, most people accessed the Internet through dial-up MODEMS, connecting to services like America Online, across plain old telephone lines. The entrance of cable providers, and cable MODEMs, allowed the edge of the Internet to explode, causing massive growth. Join Donald Sharp and I on this episode of the History of Networking as John Chapman discusses the origins of the cable MODEM, and the origins of the DOCSIS standards.

Docker V2 Github Action is Now GA

Docker is happy to announce the GA of our V2 Github Action. We’ve been working with @crazy-max over the last few months along with getting feedback from the wider community on how we can improve our existing Github Action. We have now moved from our single action to a clearer division and advanced set of options that not only allow you to just build & push but also support features like multiple architectures and build cache.

The big change with the advent of our V2 action is also the expansion of the number of actions that Docker is providing on Github. This more modular approach and the power of Github Actions has allowed us to make the minimal UX changes to the original action and add a lot more functionality.

We still have our more meta build/push action which does not actually require all of these preconfiguration steps and can still be used to deliver the same workflow we had with the previous workflow! To Upgrade the only changes are that we have split out the login to a new step and also now have a step to setup our builder.
