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.

Containerizing open-vm-tools – Part 1: The Dockerfile and constructing a systemd unit file

While validating OpenShift Container Platform on a VMware platform the usage of Atomic OS was also a requirement. In the initial reference architecture, the decision was made to use Red Hat Enterprise Linux as the platform. This platform was then customized and the same packages as in Atomic were installed via Ansible and Red Hat Network.

Microservices Deployments Evolution

Microservices Are Here, to Stay

A few years back, most software systems had a monolithic architecture and slow release cycle. In the recent years, there is a clear move towards Microservices architecture, which is optimized for scalability, elasticity, failure, and speed of change. This trend has been further enforced by the adoption of cloud and containers, which also enabled practices such as DevOps.

Trends in the IT Industry

All these changes have resulted in a growing number of services to develop and an even bigger number of deployments to do. It soon became clear that the explosion in the number of deployments cannot be controlled using pre-microservices tools and techniques, and new ways have been born. In this article, we will see how Cloud Native platforms such as Kubernetes allow deployment of Microservices in high scale with minimal human intervention.

Automate integration CI/CD process

Red Hat Fuse Integration Service 2.0 tech preview was released a few weeks ago and as it’s based on Red Hat OpenShift 3.3, which has pipeline capability on top of it (tech preview on OpenShift as well), you are able to get one step closer to a more automated and agile continuous integration. As well as, a deployment one-stop platform for us, the integration developer.

Migrating my iptables setup to nftables

Wanting to become familiar with nftables, I decided to jump in at the deep end and just use it on my local workstation. The goal was to replace the existing iptables setup, ideally without any drawbacks. The following essay will guide you through what I have done in order to achieve that.
