Celebrating 25 Years of Advocacy

It’s been a week of jubilation: The Internet Society celebrated 25 years of advocacy for an open, globally-connected, and secure Internet with events that crisscrossed the globe. The festivities kicked off at the University of California Los Angeles campus where in 1969 the first message was sent over ARPANET – the Internet’s predecessor.

On 18 September, the 25 Under 25 award ceremony honored young people around the world for their extraordinary work. Born in the age of the Internet, these everyday heroes are passionate about using it to make a positive impact on their communities. Their projects include connecting people with disabilities to employment opportunities, using AI to identify fake news, and humanizing issues affecting refugees and the LGBT community.

Just a few hours later, the 2017 Internet Society Global Internet Report: Paths to Our Digital Future was launched. The interactive report, the result of in-depth interviews, roundtables, and surveys conducted in 160 countries and 21 regions around the world, offers a glimpse into how the future of the Internet might impact humanity. The report encourages you to explore paths to our digital future, asks thought-provoking Continue reading

BrandPost: Find the Path to Networking Nirvana

Almost all enterprise-class organizations are sitting atop a pile of existing network infrastructure, dealing with the headaches of a complex hardware lifecycle. Many would like to find a smooth path to a virtual networking future in which hardware is no longer a barrier to change, but instead a gateway to flexible network options. Ask enterprise IT decision makers these days to select from a menu of connectivity options and odds are the top choice will be an “All of the above” response. They want bandwidth on demand, a manageable number of connectivity options to suit a distributed workforce, scalability, and the lowest cost. That networking nirvana may not be as far in the future as you once thought.To read this article in full or to leave a comment, please click here

At Ignite, Microsoft extends hybrid cloud beyond just infrastructure

For years Microsoft has talked about, previewed and at some times delayed the release of its Azure Stack hybrid cloud computing platform.But this week at its Ignite conference in Orlando Microsoft announced that Azure Stack is now shipping to customers, and in doing so the company is pitching its hybrid cloud platform as being about more than just connecting customer data centers to the public cloud.+MORE AT NETWORK WORLD: Azure Stack: Microsoft’s private-cloud platform and what IT pros need to know about it +To read this article in full or to leave a comment, please click here

Exciting new things for Docker with Windows Server 1709

What a difference a year makes… last September, Microsoft and Docker launched Docker Enterprise Edition (EE), a Containers-as-a-Service platform for IT that manages and secures diverse applications across disparate infrastructures, for Windows Server 2016. Since then we’ve continued to work together and Windows Server 1709 contains several enhancements for Docker customers.

Docker Enterprise Edition Preview

To experiment with the new Docker and Windows features, a preview build of Docker is required. Here’s how to install it on Windows Server 1709 (this will also work on Insider builds):

Install-Module DockerProvider
Install-Package Docker -ProviderName DockerProvider -RequiredVersion preview

To run Docker Windows containers in production on any Windows Server version, please stick to Docker EE 17.06.

Docker Linux Containers on Windows

A key focus of Windows Server version 1709 is support for Linux containers on Windows. We’ve already blogged about how we’re supporting Linux containers on Windows with the LinuxKit project.

To try Linux Containers on Windows Server 1709, install the preview Docker package and enable the feature. The preview Docker EE package includes a full LinuxKit system (all 13MB of it) for use when running Docker Linux containers.

[Environment]::SetEnvironmentVariable("LCOW_SUPPORTED", "1", "Machine")

To disable, just remove the environment variable:

Pub/Sub model could connect IoT devices without carrier networks

Three characteristics of the Internet of Things (IoT) differentiate it from industrial automation. IoT devices are inexpensive. IoT devices can be ubiquitously connected everyplace and anyplace. IoT devices have inexpensive or zero-cost deployment. It explains why we see so few IoT networks and why most of the industrial IoT forecasts are measurements of industrial automation that we have had for decades.The first one, with the exception of the issue of strong security, is easy. The second two, though, in New Jersey parlance — says easy does hard.Ubiquitous connectivity is talked about, and there is a glimmer of hope presented by Low-Power Wide-Area Networks (LPWAN) such as Senet that focus on both low-cost technology and a business model for entrepreneurial partners to deploy networks. But waiting for carriers to perfect and deploy 5G networks to build IoT solutions will delay innovators and prevent early adopters from building proof-of-concept and prototype networks essential for the iterative learning of technical methods, business cases and making financial projections of the benefits of IoT.To read this article in full or to leave a comment, please click here

Light/No Blogging this Week

I’m trying to get through the final bits of this new book (which should publish at the end of December, from what I understand), and the work required for a pair of PhD seminars (a bit over 50 pages of writing). I probably won’t post anything this week so I can get caught up a little, and I might not be posting heavily next week.

I’ll be at SDxE in Austin Tuesday and Wednesday, if anyone wants to find me there.

The post Light/No Blogging this Week appeared first on rule 11 reader.

Making good use of the files in /proc

The /proc file system first made its way into some Unix operating systems (such as Solaris) in the mid-1990s, promising to give users more and easier access into the kernel and to running processes. It was a very welcome enhancement — looking and acting like a regular file system, but delivering hooks into the kernel and the ability to treat processes as files. It went well beyond what we could do with ps and other common commands for examining processes and the system they run on.When it first appeared, /proc took a lot of us by surprise. We were used to devices as files, but access to processes as files was new and exciting. In the years since, /proc has become more of a go-to source for process information, but it retains an element of mystery because of the incredible detail that it provides.To read this article in full or to leave a comment, please click here

Internet Impacts of Hurricanes Harvey, Irma, and Maria

Hurricane Irene - Dyn Uptime

Devastation caused by several storms during the 2017 Atlantic hurricane season has been significant, as Hurricanes Harvey, Irma, and Maria destroyed property and took lives across a number of Caribbean island nations, as well as Texas and Florida in the United States. The strength of these storms has made timely communication of information all the more important, from evacuation orders, to pleas for help and related coordination among first responders and civilian rescuers, to insight into open shelters, fuel stations, and grocery stores. The Internet has become a critical component of this communication, with mobile weather applications providing real-time insight into storm conditions and locations, social media tools like Facebook and Twitter used to contact loved ones or ask for assistance, “walkie talkie” apps like Zello used to coordinate rescue efforts, and “gas tracker” apps like GasBuddy used to crowdsource information about open fuel stations, gas availability, and current prices.

As the Internet has come to play a more pivotal role here, the availability and performance of Internet services has become more important as well.  While some “core” Internet components remained available during these storms thanks to hardened data center infrastructure, backup power generators, and comprehensive disaster planning, local infrastructure Continue reading

IoT poised to impact quality, capabilities of healthcare

Everything about the modern doctor’s office feels primitive. It’s one of the few businesses that requires I use my telephone for scheduling — unless it’s about lab results. For that, they prefer fax. Even the doctor’s tools, such as the blood pressure cuff, scale and stethoscope, are largely the same as the equipment used in my childhood.I get that the industry needs to be cautious regarding change and that legal requirements further complicate matters, but changes are overdue. Because medical professionals are unlikely to adopt unproven tech, the evolution will most likely come from existing tech being used in other applications.Let’s take a look at how things might change in healthcare technology:To read this article in full or to leave a comment, please click here

IDG Contributor Network: Office 365: What’s your network deployment architecture?

I recently gave a webinar on how to best architect your network for Office 365. It comes on the heels of a number of complaints from customers around their struggles deploying responsive Office 365 implementations. SharePoint doesn’t quite work; Skype calls are unclear. And forget about OneDrive for Business. It’s incredibly slow.Latency and Office 365 Ensuring a smooth transition to Office 365, or for that matter any cloud deployment, involves a solid understanding of which Office 365 applications are being deployed. Here latency matters. Microsoft recommends that round trip latency for Office 365 does not exceed 275 ms, but those metrics change significantly depending on the Office 365 application. Latency should not exceeds 50ms with Exchange Online and 25ms with SharePoint. (Check out my “ultimate” list of Office 365 networking tools for help with your O365 deployment.)To read this article in full or to leave a comment, please click here

The Value of Configuration Consistency (Thwack)

It’s one thing to have a stable network, but it’s another to have consistency in device configurations across the network. Does that even matter?

On the Solarwinds Thwack Geek Speak blog I looked at some reasons why it might be important to maintain certain configuration standards across all devices. Please do take a trip to Thwack and check out my post, “The Value of Configuration Consistency“.
