IDG Contributor Network: Enterprises evaluate the costs of building versus buying an IoT platform

Almost every week we speak with an enterprise that is curious about building its own IoT application enablement platform (AEP) or IoT device management (DM) platform. The idea is straight-forward – an enterprise wants total control over the technology it deploys, so it chooses to hire developers to build the perfect, inexpensive platform.Then what happens? Sometimes everything goes exceedingly well and the IoT platform delivers as anticipated. Other times, the enterprise determines it takes more time and money to build a platform that anticipated it takes more staff to support the platform on-going than anticipated it is very hard to keep the platform features up-to-date compared to the features offered from best-in-class vendors’ IoT platforms the initial in-house platform was great, but scaling and modifying the platform to meet future requirements is exceedingly difficult due to the chosen platform architecture So, what are the total enterprise costs of building an enterprise-grade IoT platform versus buying IoT platform services from a third-party AEP or DM vendor? It really depends on the IoT solution that the enterprise wants to deploy.To read this article in full, please click here

We’ve Added Another Blockchain Course To Our Video Library!

 

This Course is By Joseph Holbrook and is 4 hours and 34 minutes long. You can view the full course on our streaming Site, or buy the course at ine.com.

A blockchain is a tamper-evident, shared digital ledger that records transactions in a public or private peer-to-peer network. Distributed to all member nodes in the network, the ledger permanently records, in a sequential chain of cryptographic hash-linked blocks, the history of asset exchanges that take place between the peers in the network. This course has been designed for technical architects, pre sales architects, developers and project managers who must make technical decisions about distributed architectures and development platforms.

Cisco developer push yields 500,000 DevNet members working on programmable networks

ORLANDO – Cisco’s developer program, DevNet, is on a hot streak.Speaking at Cisco Live 2018, DevNet CTO Susie Wee said the group, which was founded in 2014, now has 500,000 registered members."That’s a pretty cool milestone, but what does it mean? It means that we've hit critical mass with a developer community who can program the network," Wee said. "Our 500,000 strong community is writing code that can be leveraged and shared by others. DevNet is creating a network innovation ecosystem that will be the hub of the next generation of applications and the next generation of business."At Cisco Live the company also announced it has expanded the DevNet world to include:To read this article in full, please click here

Examining X.509 Certificates Embedded in Kubeconfig Files

While exploring some of the intricacies around the use of X.509v3 certificates in Kubernetes, I found myself wanting to be able to view the details of a certificate embedded in a kubeconfig file. (See this page if you’re unfamiliar with what a kubeconfig file is.) In this post, I’ll share with you the commands I used to accomplish this task.

First, you’ll want to extract the certificate data from the kubeconfig file. For the purposes of this post, I’ll use a kubeconfig file named config and found in the .kube subdirectory of your home directory. Assuming there’s only a single certificate embedded in the file, you can use a simple grep statement to isolate this information:

grep 'client-certificate-data' $HOME/.kube/config

Combine that with awk to isolate only the certificate data:

grep 'client-certificate-data' $HOME/.kube/config | awk '{print $2}'

This data is Base64-encoded, so we decode it (I’ll wrap the command using backslashes for readability now that it has grown a bit longer):

grep 'client-certificate-data' $HOME/.kube/config | \
awk '{print $2}' | base64 -d

You could, at this stage, redirect the output into a file (like certificate.crt) if so desired; the data you have is Continue reading

Your Personal Journey at DockerCon

DockerCon San Francisco 2018 is here! From all of us at Docker HQ we want to welcome those that have travelled to be with us in San Francisco. For this year’s DockerCon we wanted to create an experience that uniquely helps YOU figure out where you are today and where you want to go next with your containerized applications and operations. As you get to the Moscone Center in San Francisco, you’ll see signs guiding you towards various stages of the technology adoption journey. Below we’ve summarized common traits that customer like you have at each phase of the journey: once you identify where you click to jump down to some last minute guidance of sessions and activities that we think will be most helpful for each stage.

Click to jump directly to your journey stage:

  • Getting Started: If you’re new to containerization and trying to figure what this Docker thing is and why people are using it, this DockerCon experience is for you
  • First Project: Check out this experience if you’ve got the fundamentals of containerization down and are ready to move on to using the Docker container platform on a real project and build your core Continue reading

Start with Business Requirements, not Technology

This is the feedback I got from someone who used ExpertExpress to discuss the evolution of their data center:

The session has greatly simplified what had appeared to be a complex and difficult undertaking for us. Great to get fresh ideas on how we could best approach our requirements and with the existing equipment we have. Very much looking forward to putting into practice what we discussed.

And here’s what Nicola Modena (the expert working with the customer) replied:

As I told you, the problem is usually to map the architectures and solutions that are found in books, whitepapers, and validated designs into customer’s own reality, then to divide the architecture into independent functional layers, and most importantly to always start from requirements and not technology.

A really good summary of what ipSpace.net is all about ;) Thank you, Nicola!

Optimus: an efficient dynamic resource scheduler for deep learning clusters

Optimus: an efficient dynamic resource scheduler for deep learning clusters Peng et al., EuroSys’18

(If you don’t have ACM Digital Library access, the paper can be accessed either by following the link above directly from The Morning Paper blog site).

It’s another paper promising to reduce your deep learning training times today. But instead of improving the programming model and/or dataflow engine, Optimus improves the scheduling of jobs within a cluster. You can run it on top of Kubernetes, and the authors claim about a 1.6x reduction in makespan compared to the mostly widely used schedulers today.

Deep learning clusters

We’re using ever larger models, with ever increasing amounts of data (at least, whenever we can get our hands on it). In general this improves the learning accuracy, but it also increases the training time. The most common approach is parallel training using a machine learning cluster. Typically a model is partitioned among multiple parameter servers, and training data is spread across multiple workers. Workers compute parameter updates and push them to the respective parameter server.

Training is an iterative process with a dataset divided into chunks, and each chunk further divided into mini-batches. A Continue reading

Network Labs Using Nested Virtualization in the Cloud

Many open-source network simulation and emulation tools use full virtualization technologies like VMware, QEMU/KVM, or VirtualBox. These technologies require hardware support for virtualization such as Intel’s VT-x and AMD’s AMD-V. To gain direct access to this hardware support, researchers usually run network emulation test beds on their own PCs or servers but could not take advantage of the inexpensive and flexible computing services offered by cloud providers like Amazon EC2, Google Compute Engine, or Microsoft Azure.

By August 2017, most of the major cloud service providers announced support for nested virtualization. In the cloud context, Nested Virtualization is an advanced feature aimed at enterprises, but it is also very useful for building network emulation test beds. I’ve written about nested virtualization for servers before but, until recently, I was limited to running nested virtual machines on my own PC. Now that the major cloud providers support nested virtualization, I can build more complex network emulation scenarios using cloud servers.

This post will discuss the cloud service providers that support nested virtualization and how this feature supports open source networking simulation and emulation in the cloud.
