Blockchain Consolidation Phase Is Imminent, Hyperledger Chief Says
Brian Behlendorf, a driving force behind the Apache web server and longtime supporter of open source software, now spends his time developing blockchain technology for the enterprise.
As the executive director of the Hyperledger project, an open source blockchain initiative hosted by the Linux Foundation, Mr. Behlendorf is working to create enterprise-ready distributed ledger technologies and develop a community of corporate blockchain developers that will outlast a fevered investment climate.
Blockchain is still nascent in the enterprise, but the conversation has evolved beyond basic technology questions to more involved discussions about scale, interoperability and governance, Mr. Behlendorf said.

6 key data strategy considerations for your cloud-native transformation
Many organizations are making the move to cloud-native platforms as their strategy for digital transformation. cloud-native allows companies to deliver fast-responding, user-friendly applications with greater agility. However, the architecture of the data in support of cloud-native transformation is often ignored in the hope that it will take care of itself. With data becoming the information currency of every organization, how do you avoid the data mistakes commonly made during this cloud transformation journey? What data questions should you ask when building cloud-native applications? How can you gain valuable insight from your data?
The ensuing presentation includes six key considerations companies must have when they make this transition to cloud-native.

Making Kubernetes Easier with Cloud Foundry Platform
Kubernetes is one of the biggest technology disruptors to hit the IT industry in a long time — maybe since Amazon EC2, now more than a decade old. It has helped turn containers from a convenient packaging method into the building blocks of modern application architectures, and has shifted the discussion in many circles from cloud computing to cloud-native computing.
If that seems like a form of technological hair-splitting, it isn’t. Cloud-native technologies and architectures are the means by which more traditional businesses — like insurance, financial services or even heavy machinery — can transition from simply consuming cloud resources into operating like the cloud providers themselves. This is shifting the way they run their businesses, making them more agile, distributed and ready to tackle via software, whatever their businesses demand. As with most new technologies, however, it’s important to look at Kubernetes with some perspective.

Virtualized lab demonstration using a tweaked Labtainers running in a container
Labtainers is quite interesting as it allows isolating a lab in several containers running in their own dedicated virtual network, which helps distributing a lab without needing to install anything locally.
My tweak allows to run what I called the “master” container which contains the labtainers scripts, instead of having to install labtainers on a Linux host. This should help installation and distribution of labtainers, as well as deploying it on cloud platforms, some day soon. In the meantime Labtainer containers of the labs run with privileges so it’s advised to be careful, and running the whole of these containers in a VM may be safer. Maybe Labtainers will evolve in the future to integrate a containerization of its scripts. My patches are pending, but the upstream authors are currently focused on some other priorities.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
