Red Hat at the ISO C++ Standards Meeting (July 2017): Parallelism and Concurrency

Torvald Riegel

Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in July 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. We discussed several synchronization-related proposals, improvements for futures, and, of course, executors. Also, I proposed a few steps that the SG1 community could take to get more efficient in how it conducts its work, which are all inspired by how successful open source projects work. Most of the proposals we discussed...

Gluster for OpenShift - Part 1: Container-Ready Storage

davis phillips

OpenShift Container Platform (OCP) offers many different types of persistent storage. Persistent storage ensures that data should be insistent between builds and container migrations. When choosing a persistent storage backend to ensure that the backend supports the scaling, speed, dynamic provisioning, RWX/RWO support and redundancy that the project requires. Container-Ready Storage (CRS), or native Gluster for OCP, is defined by the concept of persistent volumes, which are OCP created objects that allow storage to be defined and then used by...

Testing REST APIs with REST Assured

Heiko Rupp

Note: This is an updated version of a post I wrote for my private blog years ago. While working on the REST API of RHQ a long time ago, I had started writing some integration tests against it. Doing this via pure HTTP calls is very tedious and brittle. So, I was looking for a testing framework to help me and found one that I used for some time. I tried to enhance it a bit to better suit my...

EDI Transformations with Fuse Integration Services (FIS)

Simon Green

EDI, or Electronic Data Interchange, has always been a challenging domain to support for organizations. As EDI standards cover a large range of industries, from supply chain to medical to financial services (FSI), the standards rapidly evolve and change over time, thus requiring constant maintenance. The sheer cost of maintaining standards is high, not only for organizations but also for EDI software vendors who struggle to keep up. The expensive fees paid to standards organizations and rapidly evolving releases are...

Statement Frontier Notes and Location Views

Alexandre Oliva

Surely, you too have been frustrated, while single-stepping optimized programs in symbolic debuggers, by the Brownian motion in the source code, and by never being sure, when you reach a certain source line (if you can reach it at all), whether or not earlier lines have taken effect. Our frustration is about to be significantly alleviated, thanks to two new pieces of technology about to be contributed to the GNU toolchain. Statement Frontier Notes are stable markers of source locations...

OpenShift Application Runtimes

John Clingan

One question, which is often asked of me is “How do I quickly get new features into production?” This is the whole idea of microservices, to quickly move features into production. At this year’s Red Hat Summit, I spoke to this during my OpenShift Application Runtimes session, introducing it as an upcoming product. I spoke on integrating language runtimes into OpenShift and Kubernetes so that as you write Microservices you can leverage a lot of the features that are available...

Your first Business Rules application on OpenShift: from Zero to Hero in 30 minutes

Duncan Doyle

In a previous blog post, we explained how to deploy an existing JBoss BRMS/Drools rules project onto an OpenShift DecisionServer. We created a decision/business-rules microservice on OpenShift Container Platform that was implemented by a BRMS application. The polyglot nature of a microservice architecture allowed us to use the best implementation (a rules engine) for this given functionality (business rules execution) in our architecture. The project we used was an existing rules project that was available on GitHub. We did however...

Red Hat and Apache OpenWhisk

Rich Sharples

Unless you’ve been on a complete media blackout for the last year or so (entirely understandable) you’ve likely heard a lot about Serverless (or FaaS - Function as a Service). Serverless is a major shift in the way developers build and deliver software systems - it greatly simplifies development by insulating the developer from infrastructure concerns and pushes the envelope on cost and efficiency of execution. Various groups at Red Hat have been investigating Serverless for some time now -...

2012 Red Hat Summit: Achieving top network performance

Red Hat Developer Program

In this session, Mark Wagner reviews enhancements in Red Hat Enterprise Linux 6 and show attendees how to take advantage of them in their environments. Mark uses test results from Red Hat's performance lab to highlight the various differences, advantages, and tradeoffs for many technologies, including Kernel-based Virtual Machine (KVM) virtualization technology, 10Gbit Ethernet, Infiniband, FCoE, Packet Flow Control, and RDMA. Mark also presents guidelines and tools for planning and tuning network configurations for low latency and high throughput. He covers the differences between tuning for baremetal, a KVM guest, a Red Hat Storage file system, and NFS. He also touches upon some tricks developers can use when writing network-based applications.
