Video Series: Modernizing .NET Apps for IT Pros

 mta-it-pro.jpg

This is a new 5-part video series in Docker’s Modernize Traditional Apps (MTA) program, aimed at Microsoft IT Pros. The video series shows you how to move a .NET 3.5 app from Windows Server to a Windows Docker container and deploy it to a scalable, highly-available environment in the cloud – without any changes to the app.

Part 1 introduces the series, explaining what is meant by “traditional” apps and the problems they present. Traditional apps are built to run on a server, rather than on a modern application platform. They have common traits, like being complex to manage and difficult to deploy. A portfolio of traditional applications tends to under-utilize its infrastructure, and over-utilize the humans who manage it. Docker Enterprise Edition (EE) fixes that, giving you a consistent way to package, release and manage all your apps, without having to re-write them.

Part 2 shows how easy it is to move traditional apps to Docker EE. I start with an ASP.NET 3.5 WebForms application running on Windows Server 2003, and use Image2Docker to extract the app and package it as a Docker image. Then I run the application in a Docker Windows container on Continue reading

Large BGP Leak by Google Disrupts Internet in Japan

At 03:22 UTC on Friday, 25 August 2017, the internet experienced the effects of another massive BGP routing leak.  This time it was Google who leaked over 160,000 prefixes to Verizon, who in turn accepted these routes and passed them on.  Despite the fact that the leak took place in Chicago, Illinois, it had devastating consequences for the internet in Japan, half a world away. Two of Japan’s major telecoms (KDDI and NTT’s OCN) were severely affected, posting outage notices (KDDI / OCN pictured below).

Massive routing leaks continue

In recent years, large-scale (100K+ prefix) BGP routing leaks typically fall into one of two buckets:  the leaker either 1) announces the global routing table as if it is the origin (or source) of all the routes (see Indosat in 2014), or 2) takes the global routing table as learned from providers and/or peers and mistakenly announced it to another provider (see Telekom Malaysia in 2015).

This case is different because the vast majority of the routes involved in this massive routing leak were not in the global routing table at the time but instead were more-specifics of routes that were.  This is an important Continue reading

Staples Easy Button gets IoT makeover

“That was easy” is the iconic tagline of Staples. The international retailer has used that line since 2003. In 2005, the slogan took a material shape and appeared in ads as a red “easy” button. Now, Staples is giving its next-generation of the Easy Button a serious IoT makeover.The button was meant as a metaphor to represent easy business transactions. But that didn’t stop people from wanting an actual button. Staples responded by producing Easy Buttons as a “stress relieving” novelty. Pushing the button causes it to say, “That was easy.”To read this article in full or to leave a comment, please click here

The WireX Botnet: How Industry Collaboration Disrupted a DDoS Attack

Introduction

On August 17th, 2017, multiple Content Delivery Networks (CDNs) and content providers were subject to significant attacks from a botnet dubbed WireX. The botnet is named for an anagram for one of the delimiter strings in its command and control protocol. The WireX botnet comprises primarily Android devices running malicious applications and is designed to create DDoS traffic. The botnet is sometimes associated with ransom notes to targets.

A few days ago, Google was alerted that this malware was available on its Play Store. Shortly following the notification, Google removed hundreds of affected applications and started the process to remove the applications from all devices.

Researchers from Akamai, Cloudflare, Flashpoint, Google, Oracle Dyn, RiskIQ, Team Cymru, and other organizations cooperated to combat this botnet. Evidence indicates that the botnet may have been active as early as August 2nd, but it was the attacks on August 17th that drew the attention of these organizations. This post represents the combined knowledge and efforts of the researchers working to share information about a botnet in the best interest of the internet community as a whole. This blog post was written together by researchers from numerous organizations and released Continue reading

NSX-T 2.0 is here !

VMware NSX is a network virtualization and security platform for the enterprise that is helping our customers make the transition to the digital era.  As developers embrace new technologies like containers, and the percentage of workloads running in public clouds increases, network virtualization must expand to offer a full range of networking and security services, natively, in these environments.

Today, we are announcing the next version of NSX-T that can provide network virtualization for a multi-cloud and multi-hypervisor environment. The NSX technology that you are familiar with and use it for so many years is now be available for cloud and container environments. Circa VMworld 2016, we showed a prototype of NSX that can provide network virtualization and micro-segmentation for native AWS workloads. That journey is now complete and the initial availability of that service for some customers is already available for their AWS workloads.

NSX can now provide seamless network virtualization for workloads running on either VMs or Containers. VMs can be located either on-prem or on AWS. NSX will provide the entire feature set for either Vmware vSphere Hypervisors or KVM hypervisors. For native workloads on AWS, NSX will provide VMware NSX Secure Cloud to provide the Continue reading

Google leaked prefixes – and knocked Japan off the Internet

Last Friday, 25 August, a routing incident caused large-scale internet disruption. It hit Japanese users the hardest, slowing or blocking access to websites and online services for dozens of Japanese companies.

What happened is that Google accidentally leaked BGP prefixes it learned from peering relationships, essentially becoming a transit provider instead of simply exchanging traffic between two networks and their customers. This also exposed some internal traffic engineering that caused many of these prefixes to get de-aggregated and therefore raised their probability of getting accepted elsewhere.

The incident technically lasted less than ten minutes, but spread quickly around the Internet and caused some damage. Connectivity was restored, but persistently slow connection speeds affected industries like finance, transportation, and online gaming for several hours. Google apologized for the trouble, saying it was caused by an errant network setting that was corrected within eight minutes of its discovery.

This incident showed, again, how fragile the global routing system still is against configuration mistakes, to say nothing about malicious attacks.

What it also showed is a lack of defense – the incident propagated seemingly without any attempt from other networks to stop it.

IGF-USA: Promoting a More Inclusive Internet

The IGF-USA took place in Washington D.C on July 24, 2017. During the event, the panel “Promoting a More Inclusive Internet” looked at current barriers to an inclusive Internet and explored how access could be expanded to underserved areas and to underrepresented communities. Moderated by Dr. Brandie Nonnecke, Research & Development Manager for CITRIS and the Banatao Institute at the University of California-Berkeley and Chair of the San Francisco-Bay Area Internet Society Chapter Working Group on Internet Governance, the panel brought together several experts on access provision, each with many years experience of connecting the unconnected in the USA and overseas.

Decentralized Approach

One of the main themes of the panel was that there is no ‘one size fits all’ approach to getting communities online. Rather than focus on technical deployment, the panelists argued that the focus needs to shift to what Internet access actually means to different communities and to solutions adapted to fit their specific needs. When proposing solutions, the first question that needs to be asked is, ‘What are the problems that Internet access will solve?’ Often, what works for one community won’t work for another. “No one should decide what other people’s Internet access Continue reading

The Rise Of The Fourth Wave Of Computing

According to a recent Jefferies report, the fourth wave of computing has started and it is being driven by the adoption of IoT with parallel processing as the solution. Tectonic shifts in computing have been caused by major forces dating back to the 1960s.

With each shift, new solution providers have emerged as prominent suppliers. The latest power often cited with the fourth wave is Nvidia and its parallel processing platform for HPC and artificial intelligence (AI), namely GPUs and the CUDA programming platform. The growth of the data center segment of Nvidia’s business – from $339 million in …

VNIX-NOG 2017 held in Ho Chi Minh City

VNNIC, the National Internet Registry (NIR) of Vietnam, organized 2 major events in Ho Chi Minh City. VNNIC IP Member meeting on 24th August at VNNIC HCMC Office and second VNIX-NOG event on 25th August at Saigon Prince Hotel and was attended by our Deploy360 colleague Aftab Siddiqui. NetNam, a local ISP, provided Internet connectivity for the NOG event and did a great job by providing a dual stack IPv4 and IPv6 network.

The first event was for VNNIC IP members where reports were presented and NIR policies discussed, but the NOG event the following day was attended by around 70 people from various organizations including all the major telcos and ISPs in the country, the Internet Society, APNIC, Google and BBIX.

The opening speech was provided by Nguyen Hong Thang – Deputy Director of VNNIC, and a welcome note was added by Vu The Binh – General Secretary of Vietnam Internet Association (VIA) . Presentations from the event are available here, but the emphasis was on local participants to share their experience and local community engagement.

Nguyen Tran Hieu (VNIX) shared some network statistics of the Hanoi and Ho Chi Minh City nodes, which unfortunately showed that most members Continue reading

Liveblog: VMworld 2017 Day 1 Keynote

This is a liveblog of the day 1 keynote at VMworld 2017 in Las Vegas, NV. There was a bit of a kerfluffle regarding seating (the local facilities staff didn’t want to let me sit in the bloggers’ area because “you’re not a blogger”), but I managed to snag a seat anyway.

Prior to the keynote, a number of announcements were released; here’s a quick look at a few of them:

Pat Gelsinger takes the stage at about 9:05am, after a very cool AR/VR demo. Gelsinger welcomes the crowd, and takes a minute to reflect upon his time at CEO of VMware. Gelsinger also takes a moment to talk about the devastation caused by Hurricane Harvey, and urges attendees to help support the recovery of that effort.

Gelsinger talks how “science fiction” is becoming “science fact”: exoskeletons, teleportation, and genetically modified organisms via CRISPR. Continue reading

StackStorm Architecture Part I – StackStorm Core Services

A while ago, I wrote about basic concepts in StackStorm. Since then I’ve been knee-deep in the code, fixing bugs and creating new features, and I’ve learned a lot about how StackStorm is put together. In this series, I’d like to spend some time exploring the StackStorm architecture. What subcomponents make up StackStorm? How do they interact? How can we scale StackStorm? These are all questions that come up from time to time in the StackStorm community, and there are a lot of little details that I even forget from time-to-time.
