SDNs and NFV are complementary and core components of modernized networks

The terms software defined networking (SDN) and network functions virtualization (NFV) are often used interchangeably, which is incorrect.  In a sense, the two are tied together as companies start using NFV as part of their SDN plans but that doesn’t have to be the case.Enterprises could maintain their current network architecture and shift to NFV or they could roll out an SDN and never leverage the benefits of NFV, so it’s important to understand what each is and the benefits of both.[ For more on SDN see where SDN is going and learn the difference between SDN and NFV. | Get regularly scheduled insights by signing up for Network World newsletters. ] What is software-defined Networking SDNs are a fundamentally different way to think about networks.  Technically, SDNs can be defined as the separation of the management, control and data-forwarding planes of networks.  Many people, including technical individuals read that definition and say, “So what?”, but the separation of these planes has a profound impact on networks and enables things that have never been done before.To read this article in full, please click here

Integrating 3rd Party Firewalls with Amazon Web Services (AWS) VPC Networking

After figuring out how packet forwarding really works within AWS VPC (here’s an overview, the slide deck is already available to ipSpace.net subscribers) the next obvious question should be: “and how do I integrate a network services device like a next-generation firewall I have to use because $securityPolicy into that environment?”

Please don’t get me started on whether that makes sense, that’s a different discussion.

Christer Swartz, an old-time CCIE and occasional guest on Software Gone Wild podcast will show you how to do it with a Palo Alto firewall during my Amazon Web Services Networking Deep Dive workshop on June 13^th in Zurich, Switzerland (register here).

ServiceFabric: a distributed platform for building microservices in the cloud

ServiceFabric: a distributed platform for building microservices in the cloud Kakivaya et al., EuroSys’18

(If you don’t have ACM Digital Library access, the paper can be accessed either by following the link above directly from The Morning Paper blog site).

Microsoft’s Service Fabric powers many of Azure’s critical services. It’s been in development for around 15 years, in production for 10, and was made available for external use in 2015.

ServiceFabric (SF) enables application lifecycle management of scalable and reliable applications composed of microservices running at very high density on a shared pool of machines, from development to deployment to management.

Some interesting systems running on top of SF include:

• Azure SQL DB (100K machines, 1.82M DBs containing 3.48PB of data)
• Azure Cosmos DB (2 million cores and 100K machines)
• Skype
• Azure Event Hub
• Intune
• Azure IoT suite
• Cortana

SF runs in multiple clusters each with 100s to many 100s of machines, totalling over 160K machines with over 2.5M cores.

Positioning & Goals

Service Fabric defies easy categorisation, but the authors describe it as “Microsoft’s platform to support microservice applications in cloud settings.” What particularly makes it stand out from the crowd Continue reading

An Update for my Adoring Fans

I feel like a teenage girl with a fashion blog who hasn’t posted in 6 months and comes back with “I know I haven’t posted in a while…”  Sigh.  It’s been right at a year since I actually published a post, so I figured I would give everyone an update.

I’ve had some personal things going on lately, and those have taken all of my energy.  We’ve made it through those rough times, so my energy is coming back.  I’m feeling better every day, and I hope I can get back to producing some content.  And, let me tell you…I’ve got some stuff to talk about.

*insert star wipe here*

We got a new director-level dude at the office, and he’s really mixing things up for us.  His philosophy includes changing the way we do everything that we do.  Like literally everything.  He ran a report for me on my ticket queue and showed me that 60% of my ticket count was on stupid stuff that’s below my pay grade.  His advice : Make somebody else do it.  So I did.  I taught myself some more Python (not hard since Continue reading

IDG Contributor Network: Winning together in the co-economy: a new mindset for the 21st century

During the late 20th century, industrial technology providers focused on delivering complete, turnkey solutions by themselves. The thought was that to effectively address highly specialized and complex environments, a vertically integrated approach would produce a better outcome.Today, that mindset has drastically shifted.The accelerated pace of technology innovation has driven end customers to question this single-vendor model. Now, customers are increasingly embracing the open model involving multiple partners developing solutions based on open standards and the latest technology. Such solutions are typically better future-proofed, more cost effective and agile.To read this article in full, please click here

The Value of Community

What seems, now, like a few short months ago, I was drawn into a small community known as The Network Collective. This last week, we launched our paid membership service.

The first thing that must come to mind is that there will be training. Of course there will be training. A (minor) theme throughout the community launch among Eyvonne, Jordan, and I, is that the training on tap will be different from anything else out there. We all three have a great deal of respect for the existing training materials, and we all intend to continue to be involved in other training and education efforts. On the other hand, the style, tone, and content will be different at The Network Collective. The first series being launched are math for network engineers, a long conversation on network design, and a long conversation on communication skills. But training is, once again, a minor theme.

The major theme of The Network Collective is community.

Consider the position of the “average” network engineer. You are either the expert, or one of a few experts, on a topic very few people care about in your organization. What you build is largely seen as an opaque Continue reading
