The Mass Open Cloud (MOC) is an open cloud exchange that provides compute resources to university researchers. The virtualization infrastructure is built on Red Hat OpenStack Platform, using Foreman for provisioning and Ceph for distributed storage. But the MOC has also developed its own tools to make bare metal computing available. We talked to Naved Ansari, one of the MOC developers, about some of these developments.
In a typical cloud computing environment, users are provided with a virtual machine running on the same physical machine as other virtual machines. This is a way to maximize compute resources, by not leaving too many machines unused. Virtual machines work well for a lot of workloads, but occasionally people need access to bare metal without a virtualization layer.

The Superfluidity Project was a 33-month European (H2020) research project (July 2015–April 2018) aimed at achieving superfluidity on the Internet: the capability to instantiate services on-the-fly, run them anywhere in the network (core, aggregation, edge), and shift them transparently to different locations. The project especially focused on 5G networks and tried to go one step further into the virtualization and orchestration of different network elements, including radio and network processing components, such as BBUs, EPCs, P-GW, S-GW, PCRF, MME, load balancers, SDN controllers, and others.
For more information about it, you can visit both the official project website, as well as my previous blog post.

At the first signs of Spring, all Red Hatters turn at least one eye toward Red Hat Summit. Over the years, we’ve had many conversations with attendees about what kind of information and perspectives they’d like to hear at Summit. We learned that attendees appreciated the actionable technical information they received, but that they were interested in getting some insight into Red Hat’s point of view on emerging technology trends and their thoughts on the future. That was the motivation behind a new set of sessions from the Office of the CTO that we’re very excited to announce.

Blockchain is everybody’s latest buzzword–right up there with AI and IoT–but what does it mean, and how is it relevant to the enterprise?
The answer to those questions is likely “a lot,” but before we get to that, let’s define what a blockchain is–and isn’t.

In the previous blog, my colleague David Bericat discussed why Internet of Things (IoT) architecture should be built with open source. One of the core components of end-to-end IoT architecture listed in that article was an intelligent IoT gateway that can process data near its source in near real time and filter/prioritize the actionable data. In this article, we’ll explore the reasons behind the need for an intelligent IoT gateway.

In January of 2015, the Open vSwitch (OVS) team announced they planned to start a new project within OVS called OVN (Open Virtual Network). The timing could not have been better for me as I was looking around for a new project. I dove in with a goal of figuring out whether OVN could be a promising next generation of Open vSwitch integration for OpenStack and have been contributing to it ever since.

Network Functions Virtualization (NFV) is revolutionizing the telecommunications industry. That word, “revolution”, is often misused, but it is appropriate for the transformation of core network services from physical to virtual infrastructure.

Back in January 2016, Ansible delivered the first integration of network support into the Ansible 2.0 code base. The initial introduction of network support was originally conceived to help operators focus on being able to execute configuration changes on network devices with a set of imperative-based configuration modules.
