IDG Contributor Network: How IoT is impacting mobile app development

Innovators of all stripes have tapped into the Internet of Things (IoT) as they develop the best products and services of the 21st century, but few have made as much use of the IoT as today’s mobile app developers have. By exploiting the ubiquity of today’s IoT, mobile app developers are finding hordes of new customers by the day, and show little signs of slowing down their industry’s growth.So how exactly are these app developers using the IoT to make their jobs easier? What are the common habits of successful developers, and what IoT flukes have they learned to avoid? A quick look at how the IoT and mobile development go hand in hand shows just how far this duo could go in the tech world.To read this article in full or to leave a comment, please click here

Preview: Linux Containers on Windows

Microsoft is getting ready for the next big update for Windows Server (check out today’s complimentary Microsoft blog post) and some of the new features are very exciting for Docker users. One of the most important enhancements is that Docker can now run Linux containers on Windows, using Hyper-V technology.

Running Docker Linux containers on Windows requires a minimal Linux kernel and userland to host the container processes. This is exactly what the LinuxKit toolkit was designed for: creating secure, lean and portable Linux subsystems that can provide Linux container functionality as a component of a container platform.

We’ve been busy prototyping LinuxKit support for Docker Linux containers on Windows and have a working preview for you to try. This is still a work in progress, and requires either the recently announced  “Windows Server Insider” or Windows 10 Insider builds.

 

Running Docker Linux Containers on Windows with LinuxKit

The instructions below have been tested on Windows 10 and Windows Server Insider builds 16278 and 16281.

Be sure to install Docker for Windows (Windows 10) or Docker Enterprise Edition (Windows Server Insider) before starting.

Setup Docker and LinuxKit

A preview build of  LinuxKit is available by simply running Continue reading

Custom Server Makers Set The Datacenter Pace

Makers of tightly coupled, shared memory machines can make all of the arguments they want about how it is much more efficient and easier to program these NUMA machines than it is to do distributed computing across a cluster of more loosely coupled boxes, but for the most part, the IT market doesn’t care.

Distributed computing, in its more modern implementation of frameworks running on virtual machines or containers – or both – is by far the norm, both in the datacenter and on the public clouds. You don’t have to look any further than the latest server sales statistics …

Worth Reading: Global content removals

From the Internet’s earliest days, the tension between a global communication network and local geography-based laws has been obvious. One scenario is that every jurisdiction’s local laws apply to the Internet globally, meaning that the country (or sub-national regulator) with the most restrictive law for any content category sets the global standard for that content. If this scenario comes to pass, the Internet will only contain content that is legal in every jurisdiction in the world — a small fraction of the content we as Americans might enjoy, because many countries restrict content that is clearly legal in the U.S. —Eric Goldman @ CircleID

Extreme leverages Avaya Networking to automate network management campus-wide

It’s been about two months since Extreme Networks closed on the acquisition of Avaya Networking. As I pointed out, Extreme’s first partial quarter post close was a smashing success, which indicates the company is headed in the right direction. But now the real work begins.In the two months since the close, the company has been extremely busy (pun intended) doing a bunch of things to integrate the companies, such as onboarding workers, bringing systems together and holding a unified sales conference. These things are obviously interesting and important, but the question on most customers’ minds is how long before there is integration at a product level?To read this article in full or to leave a comment, please click here

Docker Enterprise Edition for Linux on IBM Z (yes, mainframe!)

Recently we released a new version of Docker Enterprise Edition featuring expansion of the multi-architecture capabilities from Linux to Windows Server and now the IBM Z mainframe platform. Enterprise IT architecture is complex and diverse and include workloads across different server hardware types and operating systems.

Docker on IBMzDocker and IBM have partnered together to deliver the support for Red Hat Enterprise Linux, Ubuntu and SUSE Linux Enterprise Server for IBM Z (x390x) systems as certified infrastructure for Docker Enterprise Edition. This first release features support for the the IBM Z product family.

Why bring Docker containers and mainframe systems together? Enterprises across industries like financial services, government, manufacturing and more use mainframe systems for many high throughput applications. Many organizations recognize that these applications are at the core of their systems but rewriting and refactoring them for a different platform is expensive and time-consuming. By wrapping them in a container, organizations can make these applications easier to maintain and update while bringing them into the same software supply chain as other x86 applications

Multi-Architecture Support for Mainframe Systems

Docker Enterprise Edition allows for the same orchestration, security model, supply chain and integrated management that can be applied across a broader range Continue reading

Route-based IPsec VPN on Linux with strongSwan

A common way to establish an IPsec tunnel on Linux is to use an IKE daemon, like the one from the strongSwan project, with a minimal configuration1:

conn V2-1
  left        = 2001:db8:1::1
  leftsubnet  = 2001:db8:a1::/64
  right       = 2001:db8:2::1
  rightsubnet = 2001:db8:a2::/64
  authby      = psk
  auto        = start

The same configuration can be used on both sides. Each side will figure out if it is “left” or “right”. The IPsec site-to-site tunnel endpoints are 2001:db8:­1::1 and 2001:db8:­2::1. The protected subnets are 2001:db8:­a1::/64 and 2001:db8:­a2::/64. As a result, strongSwan configures the following policies in the kernel:

$ ip xfrm policy
src 2001:db8:a1::/64 dst 2001:db8:a2::/64
        dir out priority 399999 ptype main
        tmpl src 2001:db8:1::1 dst 2001:db8:2::1
                proto esp reqid 4 mode tunnel
src 2001:db8:a2::/64 dst 2001:db8:a1::/64
        dir fwd priority 399999 ptype main
        tmpl src 2001:db8:2::1 dst 2001:db8:1::1
                proto esp reqid 4 mode tunnel
src 2001:db8:a2::/64 dst 2001:db8:a1::/64
        dir in priority 399999 ptype main
        tmpl src 2001:db8:2::1 dst 2001:db8:1::1
                proto esp reqid 4 mode tunnel
[…]

This kind of IPsec tunnel is a policy-based VPN: encapsulation and decapsulation are governed by these policies. Each of them contains the following elements:

1 … 1,898 1,899 1,900 1,901 1,902 … 3,834
