Introducing The Internet Society Accessibility Special Interest Group

An ordinary day on 9th April 2019 was turned in to an extraordinary one, as our efforts bore fruit and we finally succeeded in chartering the Internet Society Special Interest Group on Accessibility. The Internet Society Accessibility Special Interest Group or ISOC Accessibility SIG/ISOC A11y SIG is intended to serve persons with disabilities to ensure the Internet and digital domain is for everyone.

Over 1.3 billion people worldwide – about 15% of the world’s population – experience some form of disability. The Accessibility SIG, with a people-centric approach, is aimed at providing interested participants a platform to discuss the Internet-related accessibility issues faced by the people with disabilities and to try to find the solutions to those issues. It also aims to provide a collective voice to a community that the UN calls the world’s largest minority.

The SIG also represents a journey for all of us who are members and who are dedicated to creating equal access to the Internet for everyone regardless of disability. The journey at the Internet Society started with the establishment of the ISOC Disability and Special Needs Chapter in 2002. Along the way, many dedicated and tireless workers, like the late Cynthia Waddell Continue reading

If you can’t address your customers and the people interacting with your network face to face, at least know where they are — anywhere in the world, anytime you want to. —Jonathan Zhang

Today’s enterprises make use of applications and services that live on-premises, in public clouds and even in edge data centers. IT has entered the multicloud era and connecting the modern enterprise isn’t easy. —aganesan

I don’t have a lot of good news for you. The truth is there’s nothing we can do to protect our data from being stolen by cybercriminals and others. —Bruce Schneier

Open source code is vital to software development at most organizations, but that doesn’t mean that enterprises have figured out how to use open source without inadvertently introducing vulnerabilities into their code. —Curtis Franklin, Jr

IT And The Exception Mentality

If you work in IT, you probably have a lot in common with other IT people. You work long hours. You have the attitude that every problem can be fixed. You understand technology well enough to know how processes and systems work. It’s fairly common in our line of work because the best IT people tend to think logically and want to solve issues. But there’s something else that I see a lot in IT people. We tend to focus on the exceptions to the rules.

Odd Thing Out

A perfectly good example of this is automation. We’ve slowly been building toward a future when software and scripting does the menial work of network administration and engineering. We’ve invested dollars and hours into making interfaces into systems that allow us to repeat tasks over and over again without intervention. We see it in other areas, like paperwork processing and auto manufacturing. There are those in IT, especially in networking, that resist that change.

If you pin them down on it, sometimes the answers are cut and dried. Loss of job, immaturity of software, and even unfamiliarity with programming are common replies. However, I’ve also heard a more common response growing Continue reading

Feedback: Data Center Interconnects

Got this feedback from a networking engineer watching the Data Center Interconnects webinar:

This webinar is an excellent overview regarding current DCI design challenges. I would highly recommend to watch it for anyone working in the networking and datacenter space. Sober networkers should watch it thoughtfully at least two times. L2 DCI fans should watch it once in a month, until reaching a solid grasp.

If only life would be as easy as that ;) Most people prefer to be blissfully ignorant of the infrastructure supporting their business, while at the same time pretending they know an awful lot about other people's jobs (see also: Dunning-Kruger effect)

In a recent podcast, we talked with our friend Angelo Luciani from Nutanix about the value of being part of a community and what that can mean for your career. We continue along that train of thought in this podcast but pivot over to the topic industry certifications. Host Brian talks again to Nick Mitchell and Eric Pulvino, two of our consultants who’ve not only taken certifications throughout their career but worked on and helped to create our open networking certification. Listen as they discuss the value of them, if any, what works for certifications and what doesn’t, who should be taking certifications and more!

As Brian mentions in the podcast, we have a social game going on for 2019 where you can win some fun prizes. Part of the game includes some flash give-aways of free CCOMP certification exam registration and more!  Head over to our EPIC Year Game page to learn more or follow us on Twitter, LinkedIn, and Facebook.

Cisco adds AMP to SD-WAN for ISR/ASR routers

Cisco has added support for Advanced Malware Protection (AMP) to its million-plus ISR/ASR edge routers, in an effort to reinforce branch and core network malware protection at across the SD-WAN.Cisco last year added its Viptela SD-WAN technology to the IOS XE version 16.9.1 software that runs its core ISR/ASR routers such as the ISR models 1000, 4000 and ASR 5000, in use by organizations worldwide. Cisco bought Viptela in 2017.  More about SD-WAN How to buy SD-WAN technology: Key questions to consider when selecting a supplier How to pick an off-site data-backup method SD-Branch: What it is and why you’ll need it What are the options for security SD-WAN? The release of Cisco IOS XE offered an instant upgrade path for creating cloud-controlled SD-WAN fabrics to connect distributed offices, people, devices and applications operating on the installed base, Cisco said. At the time Cisco said that Cisco SD-WAN on edge routers builds a secure virtual IP fabric by combining routing, segmentation, security, policy and orchestration.To read this article in full, please click here

Network Disaggregation Live Lesson

For those of you interested in the world of network disaggregation, the LiveLesson Dinesh Dutt and I recorded back in January is up on Safari Books Online as a “rough cut.” I’m not entirely certain when the official release will be available, but the rough cut versions are usually pretty good anyway. The one humorous mistake I see on the current page is the topic is listed as “travel.” Well, I do travel a lot, but I’ve never made a video on travel.

The rough cut is here.

When it comes to uptime, not all cloud providers are created equal

The cloud is not just important; it's mission-critical for many companies. More and more IT and business leaders I talk to look at public cloud as a core component of their digital transformation strategies — using it as part of their hybrid cloud or public cloud implementation.That raises the bar on cloud reliability, as a cloud outage means important services are not available to the business. If this is a business-critical service, the company may not be able to operate while that key service is offline.Because of the growing importance of the cloud, it’s critical that buyers have visibility into the reliability number for the cloud providers. The challenge is the cloud providers don't disclose the disruptions in a consistent manner. In fact, some are confusing to the point where it’s difficult to glean any kind of meaningful conclusion.To read this article in full, please click here
