On March 27, 2018, Cisco announced it was embracing disaggregation of the data center by allowing customers to run NX-OS on third-party switches and to use any network operating system on its Nexus switches. It’s certainly an interesting move, considering that they’re the company that claimed to have killed white-box networking.

…But does this model REALLY fit the definition of network disaggregation? What does true data center disaggregation look like? Why did Alanis Morissette name the song “Ironic” when none of the lyrics are examples of irony?? To answer these questions, I invited Ben Ritter (Consulting Engineer, Cumulus Networks) and Rama Darbha (Senior Consulting Engineer, who you’ll remember from our second episode — get ready for more #RamaRants!) into the recording booth so we can get to the bottom of this. In addition to breaking down the definition of data center disaggregation, Rama, Ben and I go full John Lennon and imagine a perfect world, where Cisco actually embraces the true spirit of disagreggation. How would this impact the industry? Imagine there’s no black box…it’s easy if Continue reading

In this post, we present ARTEMIS (Automatic and Real-Time dEtection and MItigation System), a defence system that can be used by operators to protect their own network from BGP prefix hijacking events. Using real experiments, we’ve shown that ARTEMIS can detect prefix hijacking events within seconds and neutralize them within a minute; orders of magnitude faster than with current practices. —Vasileios Kotronis @APNIC

You could sum up the security advantages of serverless this way: What containers did for ensuring the operating system and hardware layer could be maintained and secured separately, serverless offers the same at the application and web server layer. And yet — serverless is no silver bullet from a security perspective. Serverless environments still need to be designed and managed with security in mind at every moment. —Vince Power @The New Stack

Another lesson is that privacy defenses don’t need to be perfect. Many researchers and engineers think about privacy in all-or-nothing terms: a single mistake can be devastating, and if a defense won’t be perfect, we shouldn’t deploy it at all. That might make sense for some applications such as the Tor browser, but for everyday users of mainstream browsers, the threat model is death by Continue reading

Introducing Docker Application Guides

In April of 2017 we announced the Modernize Traditional Applications (MTA) program at Docker. The goal of MTA is to take the vast back catalogs of existing applications that are running in enterprise organizations today, and bring them to a modern container platform, without requiring extensive rewrites or refactoring. I’m excited to share part of our learning from the MTA program and announce the release of Docker Application Guides.

 

Oracle WebLogic MedRec Sample Application on Docker Enterprise Edition

Docker Application Guides demonstrate how to deploy popular enterprise applications – Oracle WebLogic and IBM MQ with WebSphere Liberty – on Docker Enterprise and Docker Desktop. Application Guides include example architectures and guidance for selecting Certified Docker container images from Docker Store and deploying a prototype application, orchestrated by Docker Swarm or Kubernetes.

It is important to note that Docker Application Guides are one piece of our prescriptive Docker customer journey to production. In addition to the knowledge transfer and process transformation that come with our full approach, Application Guides provide a reference for deploying common enterprise applications on the Docker Enterprise platform.

The first Docker Application Guides are designed to help you plan and deploy an Oracle WebLogic application Continue reading

Show 399: Open Networking In Production

Today, we talk to network architect Andrey Khomyakov, who s helped his organization make the transition from traditional to open networking in production.

What s it like to disaggregate switch hardware from network operating system? Was it hard? Does it really work? What s support like? Was any money saved? Will I get fired for suggesting my company go the open networking route? Andrey will answer these and more questions.

Pete Lumbis, long time friend of the Packet Pushers and contributor to the networking community, also joins with some of his insights learned in his role at Cumulus Networks. This is not a sponsored show. We just want to share the real-world experience of going new-school disaggregation with your networking.

We’ll look at the distinctions between open networking, disaggregation, and whitebox. We’ll also look at day-to-day operations with whitebox, common problems, how to choose a whitebox, and more.

Community Networks Can Help Solve World’s Problems, Ebook Says

By bringing broadband to new areas, community networks can help end discrimination, fight climate change, and feed the hungry of the world, says a report newly available as an ebook.

Community networks can help the United Nations achieve its Sustainable Development Goals, including an end to poverty and universal clean water, by bringing Internet service, and along with it, investment into areas not yet covered, says the report, Community Networks: the Internet by the People, for the People.

For the U.N. to reach its Sustainable Development Goals by 2030, nations and organizations will need to spend approximately US$1 trillion, noted Kathryn Brown, president and CEO of the Internet Society and a coauthor for the report.

While the goals are ambitious, they can be accomplished, with help from Internet access, Brown wrote in the report. “The Internet itself is an enabler for the goals,” she said. “We will be able to get there faster and in a way that lasts, if everyone can access the Internet and benefit from it.”

The report, available online since December, was recently released as a ebook on Amazon.com as a way to more widely distribute it. Supported by the Internet Society, Continue reading
