What is fog computing? Connecting the cloud to things

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.To read this article in full, please click here

CEO Succession at the Internet Society – Status update

A few weeks ago we informed the community about the fact that Kathy Brown was not going to seek another extension of her contract and, thus, a CEO search process had started at the Internet Society (ISOC). Please read my previous blog post for background.

In particular, we had asked the community to send us preliminary input, which is treated as confidential within the ISOC board, to the following email address:

[email protected]

We want to thank the community for all the useful input we have received so far. Please, continue sending us your thoughts around this important process for ISOC.

The status of the process at this point is the following. The board has set up a search committee, which is a subset of the board. The role of the search committee is to do a preliminary review of the candidates (in coordination with the selected search firm) and eventually present a short list to the full board, which will be responsible for the final selection.

The search committee is currently finishing the selection of a search firm to support us during the whole process. We have developed a draft job description, which will be finalized once a Continue reading

History Of Networking – Paul Mockapetris – Origins of DNS

Paul Mockapetris, co-inventor of the Domain Name System, joins Network Collective to talk about how DNS grew from an undesirable computer science experiment to one of the critical services that makes the Internet what it is today.

Introducing Cloudflare Access: Like BeyondCorp, But You Don’t Have To Be A Google Employee To Use It

Introducing Cloudflare Access: Like BeyondCorp, But You Don’t Have To Be A Google Employee To Use It

Tell me if this sounds familiar: any connection from inside the corporate network is trusted and any connection from the outside is not. This is the security strategy used by most enterprises today. The problem is that once the firewall, or gateway, or VPN server creating this perimeter is breached, the attacker gets immediate, easy and trusted access to everything.

There’s a second problem with the traditional security perimeter model. It either requires employees to be on the corporate network (i.e. physically in the office) or using a VPN, which slows down work because every page load makes extra round trips to the VPN server. After all this hassle, users on the VPN are still highly susceptible to phishing, man-in-the-middle and SQL injection attacks.

A few years ago, Google pioneered a solution for their own employees called BeyondCorp. Instead of keeping their internal applications on the intranet, they made them accessible on the internet. There became no concept of in or outside the network. The network wasn’t some fortified citadel, everything was on the internet, and no connections were trusted. Everyone had to prove they are who they say they are.

Server vendors push flex pricing to challenge cloud providers

For some time now, server unit sales have been steadily dropping for the major x86 server vendors as enterprises draw down their on-premises hardware in favor of cloud services.The response from the hardware vendors is if you can’t beat ‘em, clone ‘em. Vendors are adopting a pay-as-you-go model not unlike that of a cloud provider, where you pay for how much compute time you use and hand back the hardware when you are done rather than buying it outright.+Check out our review of rack servers from  HP, Dell and IBM and tips on calculating the true cost of cloud migration+To read this article in full, please click here

Ansible, Chef, Puppet or Salt? Which One Should I Use?

One of the first things I did when I started my deep-dive into network automation topics was to figure what tools people use to automate stuff and (on a pretty high level) what each one of these tools do.

You often hear about Ansible, Chef and Puppet when talking about network automation tools, with Salt becoming more popular, and CFEngine being occasionally mentioned. However, most network automation engineers prefer Ansible. Here are a few reasons.

BrandPost: Customers will see many upsides to new SD-WAN services & features

The early days of offering a managed SD-WAN service that provides basic network connectivity are drawing to a close. There is clearly burgeoning demand from customers to manage the network providers and network types that make up the growing mix of SD-WAN bandwidth options.As customers see the value of having different network providers and networks to improve reliability and overall cost per megabit for bandwidth, service providers increasingly will be needed to manage those networks and providers. This is one of the basic tenets for revenue opportunities from SD-WAN services. And with many providers, those revenue opportunities may include the use of wholesale agreements to improve the margin of network services along with the revenue inherent in managing multiple providers for customers.To read this article in full, please click here

NetDevOpEd: Abstracting configuration management

I was talking to a banking customer in Northern Europe the other day and they asked me about configuration management. They had many different vendors with different management methods in their infrastructure and wanted to know how they could speed up management.
This specific customer had an outsourced infrastructure. They picked what hardware they wanted to run, but then paid a managed services company to deploy the infrastructure in a colocation facility and perform day-to-day operations.

The issue arose in the speed of deployment. When they launched a new application that required a new service in their data center, the application engineers would need to contact the network team in this bank. The network team would then open up a ticket with the managed services company to provision VLANs and open up ports on their firewalls to allow access to the application. The issue was that this process took up to one week to complete.

This bank contacted us with the hope we could help them unify their management under one framework, so that they could insource the firewall configuration to accelerate their application deployments. They asked me about automated management best practices.
Normally when I have this conversation, we Continue reading

Worth Reading: The software defined future of the data center

“Future proofing” was once synonymous with long-range planning—essentially, life-cycle management that enables data center facilities and hardware investments to deliver full value before redevelopment or replacement. The definition has steadily evolved to connote a flexible, resilient architecture capable of supporting accelerated business-driven digital transformation. —Paul Mercina @The Data Center Journal
