Achieving Deployment Excellence with Red Hat OpenShift.io

Recently, the focus on the continuous delivery of value has created a lot of interest in microservices, CI/CD, and containers. The idea is that microservices are small and well defined enough to enable rapid innovation, automated testing, and frequent deployments with minimal risk. This is made possible by adopting continuous integration and continuous delivery pipelines. CI/CD requires the ability to quickly, easily, reliably, and automatically create and tear down complete execution environments. Linux containers address this need by creating lightweight, portable, and isolated runtime environments. It becomes easy to reach the conclusion that the path to digital transform is continuous value delivery via microservices-based on containers and CI/CD.

OpenShift.io The Gathering – Summit 2017 – Developer Tools, Overview and Roadmap Part I

Yesterday, at Red Hat Summit, Red Hat announced OpenShift.io. OpenShift.io is the next generation OpenShift platform, based on OpenShift 3, for building and running applications in the cloud. It gives you complete control of your application’s lifecycle, from build to production– regardless of deploying from source or running a pre-built container.

Increasing developer confidence and reducing development risk with Red Hat OpenShift.io Analytics

Developers often ask themselves these questions:

  • Is this the right dependency to add for the feature that I need to build?
  • What open source libraries and/or packages are others using?
  • Is this a stable and secure version?
  • Does this package’s license conform to my organization’s policies?

These are important questions that developers need to answer when choosing open source software components for their project. It is nearly impossible to deliver a modern application without depending on a number of software packages. It’s hard to justify spending time on the decision process since it doesn’t seem to add any visible business value. However, each component included is a potential liability if it has bugs or security vulnerabilities.

The Power of Cloud Workspaces in Red Hat OpenShift.io

Installing software is a drag

Getting a team set up to work on a new software project can be quite time consuming. You have some great ideas for the code you want to write, but you can’t get down to writing it until you have a development environment for yourself and the rest of the team.

First, you have to select, download, and install tools. There are usually some settings that need to be configured for each one. Then, every other developer on the team needs to do the same thing, and you have to explain it or write up instructions. This is even more challenging if some of your workers are remote or in different time zones.

The more software you install, the more burdensome it is to keep it all up to date. As you update software, you need to make sure the rest of the team keep their environments updated to avoid consistency problems. After adding new versions of software to your environment, any instructions or scripts you wrote for onboarding new team members become out of date.

Red Hat OpenShift.io: An end-to-end, cloud-native, team development experience

Digital transformation is about evolving into a technology business to compete in the digital economy. Businesses can’t transform without relying on the developer to implement the transformation strategy and deliver value. Unfortunately, as developers look to adopt new approaches that let them deliver business value more quickly, they find it challenging to get started in a timely fashion.

Red Hat Summit 2017 – Planning your Cloud and Containers Labs

This year in Boston, MA you can attend the Red Hat Summit 2017, the event to get your updates on open source technologies and meet with all the experts you follow throughout the year.

It’s taking place from May 2-4 and is full of interesting sessions, keynotes, and labs.

This year I was part of the process of selecting the labs you are going to experience at Red Hat Summit and wanted to share them to help you plan your cloud and containers labs experience. These labs are for you to spend time with the experts who will teach you hands-on and how to get the most out of development with containers and in the Cloud using products like OpenShift Container Platform.

Each lab is a 2-hour session, so planning is essential to getting the most out of your days at Red Hat Summit.

As you might be struggling to find and plan your sessions together with some lab time, here is an overview of the labs, you can find the exact room and times in the session catalog. Each entry includes the lab number, title, abstract, instructors, and is linked to the session catalog entry:

Benchmarking nftables

Since I’ve learned about nftables, I heard numerous times that it would provide better performance than its designated predecessor, iptables. Yet, I have never seen actual figures of performance comparisons between the two and so I decided to do a little side-by-side comparison.
