Campus design feature set-up : Part 3

We’ve said it before but since it’s important we’ll say it again. Shared knowledge makes for a stronger ecosystem! With this in mind, I’m showing you how to set up the CL 3.7.5 campus feature: Multi-Domain Authentication in a 6-part blog series.

In this series we’re covering it all: Wired MAC Authentication using Aruba ClearPass, Multi-Domain Authentication using Aruba ClearPass, Wired 802.1x using Cisco ISE, Wired MAC Authentication using Cisco ISE, and Multi-Domain Authentication using Cisco ISE.

This third guide is how to enable Multi-Domain Authentication in Cumulus Linux 3.7.5 + using Aruba ClearPass 6.7.x.

Keep in mind that this step-by-step guide assumes that you have already performed an initial setup of Aruba ClearPass and read the following Wired 802.1x using Aruba ClearPass and Wired MAC Authentication using Aruba ClearPass.

Over the past year, Cumulus Networks has made a concerted effort to expand the breadth and scope of the campus features within Cumulus Linux. Hot off the press in 3.7.5 is one of those features, Multi-Domain Authentication (MDA).

Classically, MDA allows for a voice VLAN and data VLAN to be configured independently on the same switch port for a VoIP Continue reading

Interview with John Kindervag, the Godfather of Zero Trust Networking

Last month, I had the pleasure of spending a few minutes with John Kindervag, the industry-described “Godfather” and thought leader behind Zero Trust Networking. John developed these concepts during his tenure as Vice President and Principal Analyst at Forrester Research. Zero Trust, rooted in the principle of “never trust, always verify,” is primarily designed to …

Announcing Docker Enterprise 3.0: Delivering High-Velocity Application Innovation

Today at DockerCon, we’re excited to announce Docker Enterprise 3.0 – the only desktop-to-cloud enterprise container platform enabling organizations to build and share any application and securely run them anywhere – from hybrid cloud to the edge.

With Docker Enterprise 3.0, developers can rapidly build multi-service container-based applications right from their desktop and package them in a standardized format that can be shared seamlessly and run anywhere. In addition, Docker Enterprise 3.0 expands its container platform leadership position with the introduction of new capabilities for automated lifecycle management and enhanced security.

Here are some of the highlights that you can look forward to in Docker Enterprise 3.0.

Accelerated application delivery

Enterprises are looking for ways to quickly adapt to new competitive challenges and changing customer requirements through the introduction of new applications. Docker Enterprise 3.0 introduces a number of capabilities that help organizations accelerate application delivery.

Docker Desktop Enterprise

Docker Desktop Enterprise is a new developer tool that extends the Docker Enterprise Platform to developers’ desktops, improving developer productivity while accelerating time-to-market for new applications.

  • Application Designer interface: template-based workflows for creating containerized applications – no Docker CLI commands are required to get started
  • Configurable version packs: Continue reading

AWS Is Now The Largest Systems Business In The World

Dell, VMware Team Up To Tackle The Hybrid Cloud

As enterprises shift more of their workloads into public clouds and grow out their multicloud strategies – many are using three or more public clouds for their applications and data to as much  protect them against problems with the cloud provider as to take advantage of particular strengths that each cloud provider offer – there can be the tendency to think that many will end up putting everything in the cloud. …

2019 Customer Innovation awards: 6 Stories of Transformation in the Enterprise

We are thrilled to honor six of our enterprise customers with the 2019 Docker Customer Innovation Award today at DockerCon. We launched the awards last year to recognize customers who stand out for how they are using  Docker Enterprise to drive transformation within IT and their business.

These are companies ranging from cruise lines to established “brick and mortar” enterprises, some of whom have been in business for well over 100 years. These are their stories.

Creating Exceptional Experiences: Carnival Corporation

         

Carnival’s first commitment is to creating fun, memorable and safe experiences for its guests. As the largest cruise line in the world, Carnival hosts over 12 million customers annually on 110 ships and at 15 resorts. Technology plays a key role in providing a world-class consistent customer experience.

Commentary: We’re stuck with 40 years old technology

One of my readers sent me this email after reading my Loop Avoidance in VXLAN Networks blog post:

Not much has changed really! It’s still a flood/learn bridged network, at least in parts. We count 2019 and talk a lot about “fabrics” but have 1980’s networks still.

The networking fundamentals haven’t changed in the last 40 years. We still use IP (sometimes with larger addresses and augmentations that make it harder to use and more vulnerable), stream-based transport protocol on top of that, leak addresses up and down the protocol stack, and rely on technology that was designed to run on 500 meters of thick yellow cable.

How to shop for enterprise firewalls

Firewalls have been around for years, but the technology keeps evolving as the threat landscape changes. Here are some tips about what to look for in a next-generation firewall (NGFW) that will satisfy business needs today and into the future.Don't trust firewall performance stats Understanding how a NGFW performs requires more than looking at a vendor’s specification or running a bit of traffic through it. Most firewalls will perform well when traffic loads are light. It’s important to see how a firewall responds at scale, particularly when encryption is turned on. Roughly 80% of traffic is encrypted today, and the ability to maintain performance levels with high volumes of encrypted traffic is critical.To read this article in full, please click here
