Develop Applications in a Hybrid World

Celebrating the builders

Harry Mower

One of the most significant shifts that developers have had to face has been the coming of age of the hybrid cloud. Cloud-native paradigms like microservices and Linux containers–and now serverless–have shaken up traditional application development practices. Modern application development in a cloud-native world requires developers to apply new tools and new ways of thinking. When we introduced the Red Hat Developer program in 2015, our goal was to build a community and provide a space where developers could come...

Zero to Express on OpenShift in Three Commands

Lucas Holmquist

With the recent announcement that Node.js is available as part of Red Hat OpenShift Application Runtimes, I wanted to see how easy it was to deploy an Express.js app on Red Hat OpenShift. It was quite easy to go from zero to having an Express app deployed and running. I show how using npx and nodeshift.

Istio: It makes a mesh of things

Don Schenck

this is an introduction to Istio. Istio helps automate the developer time to implement a feature. The combination of code complexity and code heft (i.e. number of lines of code) can put a drag on an implementation. Istio is a better way.

Accelerating the development of Node.js using OpenShift

Cesar Valdez

In this blog entry, I want to introduce a "different" way to work with OpenShift. In the typical way to deploy a Pod to OpenShift, we have available a set of very useful objects we have build/image configurations. This takes the pain from us by hiding the details about image construction but, sometimes we just want to see some code running in the cloud. Or we want to see if our service/application is able to interact with nearby services or...

First steps in integration of Windows and Linux Containers in OpenShift

Glenn West

I've started an interesting exploration on the integration of Microsoft Windows Containers and Linux Containers in an OCP Environment. This allows a true bi-modal IT technical implementation by combining the strength of both platforms into one cluster. So, I start this off, with the deployment of an OpenShift Cluster on Azure, using the 3.6 reference architecture. After this is run, I used the Azure Portal to add a Windows Server 2016 Node to the cluster. So if you look closely...

Profiling NodeJS applications with Linux Performance Tools

Cesar Valdez

Using Linux Perf Tools The Performance Analysis Tool for Linux ( perf ) is a powerful tool to profile applications. It works by using a mix of hardware counters (is fast) and software counters, all provided by the Linux Performance Counter (LPC) subsystem that takes charge of the complex task of wrapping the CPU counters for the different type of CPUs. So you can have access to a very efficient way to get information of running processes through their C...

Working with peer, scoped and private npm dependencies in RHMAP

David Martin

RHMAP Environments An RHMAP Environment provides a Node.js runtime for Mobile Backends. There are 2 environment types: Dynofarm & OpenShift. The former is an LXC based PaaS, written in Node.js & bash. It is superseded by OpenShift environments. However, there are still many Dynofarm environments in use in the RHMAP SaaS offering. fh-npm Rationale fh-npm is a wrapper for npm. It is only used in Dynofarm environments to install npm dependencies specified in a package.json file. It was developed by...
