BrandPost: Performance Drives Innovation and Security Vendors Need to Keep Up

In 1969, the very first e-message was sent over the ARPANET from computer science Professor Leonard Kleinrock's UCLA laboratory to a network node located at Stanford. That event kicked off a digital revolution that has utterly transformed our world. And ever since that first defining moment, the one question that has driven nearly all subsequent digital innovation has been: “How can we do this even faster?”We are still wrestling with that same challenge today. The latest advances in computing, such as edge device hyperconnectivity and the hyperscalability achievements of advanced data center architectures are the result of the desire to achieve better performance. Speed is the driving force behind the digital transformation of today’s business infrastructures. It enables access to critical data and resources, drives business efficiencies, scales application development, increases productivity, generates revenue, and accelerates ROI.To read this article in full, please click here

The Never-Ending "My Overlay Is Better Than Yours" Saga

I published a blog post describing how complex the underlay supporting VMware NSX still has to be (because someone keeps pretending a network is just a thick yellow cable), and the tweet announcing it admittedly looked like a clickbait.

[Blog] Do We Need Complex Data Center Switches for VMware NSX Underlay

Martin Casado quickly replied NO (probably before reading the whole article), starting a whole barrage of overlay-focused neteng-versus-devs fun.

IBM consolidates storage products under a single brand

IBM says it is consolidating its Storwize and the Flash Systems lines of storage products under a single family, the FlashSystem, that will span from entry level to advanced. It also announced a trio of all-flash storage products, spanning a range of use cases.Eric Herzog, chief marketing officer and vice president of worldwide storage channels for IBM storage, made the announcing in a pair of blog posts here and here. He noted that different organizations have different requirements for storage, and that storage vendors have traditionally responded with unique storage platforms to meet themTo read this article in full, please click here

5 Hot network-automation startups to watch

With the combined challenges of tight IT budgets and scarcer technical talent, it’s becoming imperative for enterprise network pros to embrace automation of processes and the way infrastructure responds to changing network traffic.Not only can automation help address these problems, they can also improve overall application-response time by anticipating and addressing looming congestion. Modern applications, such as virtual reality and artificial intelligence, and architectures that incorporate IoT and hybrid cloud have yet to reach their true potential because network capacity seems to always lag behind demand.  A common problem is that too much networking infrastructure is still manually maintained and managed, but major vendors are starting to addressing these  issues, as are startups that seek to break bottlenecks through automation.To read this article in full, please click here

VXLAN/EVPN vs VRF Lite

A little background information first.

When having a business requirement of tenancy, most solutions will tend to lean towards VRF. That is because VLANs require a distributed L2 environment, which comes with spanning tree, mlag and a whole other glut of inefficient network control plane protocols. Upleveling the infrastructure to L3 ends up requiring VRF technology to enforce tenancy.

Once you’ve settled on this feature as the solution for the business requirement, the next question is: How do I successfully deploy VRFs in a large distributed environment at scale, that also allows me to minimize the burden of management while still enforcing tenancy in all the important parts of my network? Most conversations surrounding this question will lead down two solution paths:

1. VXLAN with EVPN
2. VRF Lite

Definitions of VXLAN with EVPN and VRF Lite.

VXLAN with EVPN leverages VRFs at every border and leaf switch, while all the intermediate devices (ie. spines, super spines) only see the encapsulated VXLAN traffic, and hence do not need any VRF intelligence or visibility.

A VRF Lite solution is fundamentally simpler since it uses less moving parts. The thought of enabling the EVPN address family and encapsulating traffic into a VXLAN tunnel Continue reading

The Week in Internet News: CIA Had Encryption Backdoor for Decades

We’re watching you: The U.S. CIA secretly had an ownership stake in Swiss encryption company Crypto AG for decades and was able to read encrypted messages sent using the company’s technology, the Washington Post reports. West German intelligence agencies worked with the CIA. Forbes columnist Jody Westby called for a congressional investigation.

We’re watching you, part two: Meanwhile, Russia’s Federal Security Service has ordered some large Internet companies in the country to give it continuous access to their systems, the New York Times reports. The FSB has targeted more than 200 companies, including popular messenger service Telegram, social network VK. and classified advertisement website Avito.ru.

Big bucks for space-based Internet: Astranis, a satellite Internet startup focused on bringing service to underserved areas, has raised $90 million in new funding, Fortune says. The new funding will help Astranis deploy its first satellite, focused on providing Internet service in Alaska.

Not so fast: Satellites, however, have some downsides, according to a story on TheConversation.com. Satellites are vulnerable to cyberattacks, with hackers potentially able to shut them down or even turn them into weapons, the story suggests.
