Fog computing is the concept of a network fabric that stretches from the outer edges of where data is created to where it will eventually be stored, whether that's in the cloud or in a customer’s data center.

Fog is another layer of a distributed network environment and is closely associated with cloud computing and the internet of things (IoT). Public infrastructure as a service (IaaS) cloud vendors can be thought of as a high-level, global endpoint for data; the edge of the network is where data from IoT devices is created.

Fog computing is the idea of a distributed network that connects these two environments. “Fog provides the missing link for what data needs to be pushed to the cloud, and what can be analyzed locally, at the edge,” explains Mung Chiang, dean of Purdue University’s College of Engineering and one of the nation’s top researchers on fog and edge computing.

How Cisco’s newest security tool can detect malware in encrypted traffic Wed, 10 Jan 2018 10:24:00 -0800 Brandon Butler Brandon Butler

Cisco’s Encrypted Traffic Analytics (ETA), a software platform that monitors network packet metadata to detect malicious traffic, even if its encrypted, is now generally available.

The company initially launched ETA in June, 2017 during the launch of its intent-based network strategy and it’s been in a private preview since then. Today Cisco rolled ETA out beyond just the enterprises switches it was originally designed for and made it available on current and previous generation data center network hardware too.

Public – not hybrid – cloud dominates day 1 at Amazon re:Invent Thu, 30 Nov 2017 08:15:00 -0800 Brandon Butler Brandon Butler

There’s been a resurgence in the IaaS cloud computing market in the past year of vendors talking more and more about hybrid cloud computing.

As the cloud market is maturing, users are crystalizing what workloads are best for public cloud and what will remain on premises or in a private cloud. At Amazon Web Service’s annual re:Invent conference in Las Vegas this week, a big question heading into the show was: What would AWS say about hybrid?

+MORE AT NETWORK WORLD: What is hybrid cloud computing? +

Hybrid has been somewhat of a taboo topic for AWS over the years. AWS CEO Andy Jassy has repeatedly maintained that “in the fullness of time” he expects most workloads will run in the public IaaS cloud. We’re not there yet, though. A 451 Research poll from last year found that just 6% of enterprise workloads are running in the cloud.

Why 2018 will be the year of the WAN Wed, 29 Nov 2017 06:48:00 -0800 Brandon Butler Brandon Butler
nw forecast intro mini logo IDG

Software-defined WAN (SD-WAN) technology is sweeping across the industry, growing from an emerging technology in 2017 to become mainstream in 2018.

Research firm IDC predicts SD-WAN revenues will hit $2.3 billion in 2018, growing 69% on a compound annual growth rate to reach more than $8 billion by 2021. “2017 saw a lot of early adopters of SD-WAN that were limited to maybe two or three sites,” says IDC networking analyst Brad Casemore. “Now, rollouts are getting a lot bigger; we’re starting to see hockey-stick inflection point.”

nw forecast intro mini logo IDG

Despite the public cloud seemingly grabbing the lion’s share of attention in the cloud market, private and hybrid cloud computing markets have been growing robustly as well and experts predict they will only gain importance in 2018 and beyond.

“Few companies have enjoyed the expected benefits of private infrastructure-focused clouds, but a renewed focus on developer empowerment, stepping into cloud on-premises first, and a raft of new tech stack (will) spark new private cloud interest and experimentation,” Forrester research analyst Dave Bartoletti and colleagues predict in their 2018 look-ahead for the cloud market.

As the preeminent networking company shapes its plans for 2018, analysts and users say Cisco is at somewhat of an inflection point, transitioning from a hardware-based company to an integrated hardware and software-focused one.

In doing so, Cisco has plotted the next generation of its network management products in the form of intent-based networking. Meanwhile, as hardware sales growth slows due to workloads shifting to the public cloud, the company eyes the Internet of Things and edge computing as new frontiers for revenue growth.

What to consider when deploying a next-generation firewall Wed, 08 Nov 2017 10:51:00 -0800 Brandon Butler Brandon Butler

Firewalls have become ubiquitous across enterprises over the past decade, but the combination of new and varied access methods combined with increasingly sophisticated attacks has forced network operators and security professionals to constantly evaluate their defenses. 

Typically, firewalls are on a five-year refresh cycle, according to Gartner researcher Adam Hils, and that gives organizations the opportunity to evaluate fairly regularly what type of firewall and what features best suit their needs.

Amazon and Google make it easier to connect to the cloud Tue, 07 Nov 2017 10:36:00 -0800 Brandon Butler Brandon Butler

As more organizations look to enable hybrid cloud computing, a big question remains: How do I connect my network to the cloud? This week Google Cloud Platform and Amazon Web Services each released new products that make that process easier.

Google’s Dedicated Interconnect is now generally available

Dedicated Interconnect is an important way for customers to connect to the public cloud. It allows organizations to connect their on-premises resources to a colocation facility and then that co-lo facility has a direct network connection to the public cloud. Public IaaS cloud providers like Google want to give their customers access to fast connections to their cloud, but they don’t want to connect to each individual customer’s site, so they’ve created this co-lo based Interconnect. Google runs the Interconnect and offers either a 99.9 or 99.99% service level agreement. Google is working with a handful of colocation vendors as the middle-man, including Equinix, Digital Realty and Infomart.

What’s really behind the Cisco-Google hybrid cloud partnership Wed, 25 Oct 2017 10:18:00 -0700 Brandon Butler Brandon Butler

Cisco and Google have teamed up on a hybrid cloud partnership that will allow IT managers and application developers to use Cisco tools to manage their on-premises environments and link it up with Google’s public IaaS cloud.

It’s the latest partnership for Google’s cloud since former VMware CEO Diane Greene took over management of the company’s cloud operations. Google has inked similar pacts with VMware and hyperconverged infrastructure vendor Nutanix.

For Cisco though, the deal with Google marks an evolution in the company’s cloud strategy, one that has gone through many iterations in recent years.

A closer look  

Since the dawn of the hyper-scale IaaS public cloud movement, Cisco has pivoted its cloud strategy a handful of times. The company initially made an effort to build an Intercloud, a network of its partner providers running Cisco gear that would be interconnected and allow customers to shift workloads around. In the face of massive growth from Amazon Web Services, Microsoft Azure and Google Cloud Platform, that strategy went by the wayside.
