In Network Function Virtualization, there is a need to scale functions (VNFs) and infrastructure (NFVi) across multiple NUMA nodes in order to maximize resource usage.
In this blog, we’ll show how to configure Open vSwitch using DPDK datapath (OVS-DPDK) parameters for multiple NUMA systems, based on OVS 2.6/2.7 using DPDK 16.11 LTS.

The March/April C++ meeting was back in Kona, Hawaii again, only a year and a half after the last Kona meeting. As usual, Red Hat sent three of us to the meeting: Jonathan Wakely, Torvald Riegel, and me.

In a previous post, we introduced QinQ support for Open vSwitch. This post will investigate how QinQ performs relative to alternatives (VXLAN, GENEVE) in both throughput and CPU utilization. This will give us some understanding why we might consider QinQ over VXLAN or GENEVE.

Last Sunday, I returned home, India, after attending a series of collaborative sessions in Raleigh, NC, with many designers and developers across Red Hat and the open-source community, at the UX Summit and the PatternFly Conference. The whole experience was inspiring, informative and at the same time thought provoking with many takeaways, out of which the most interesting for me was that cumulatively all the inspiring talks from the speakers of the conference were implicitly hinting towards a clue. How our attempt to solve the existing technical solutions also impact the existing work process and thereby demand a rethink on the process blocks we use.

It’s been almost a month after the first world edition of API Escape room at the Red Hat Summit in Boston. We thought you might be interested to hear details on how we prepared this event.
With the 3scale team, we often participated in classical hackathons where developers gather for 48 hours to come up with a working prototype. These were awesomely fun (!), but the outcomes of those events are quite uncertain for organizers, sponsors, and participants. You cannot guarantee that hackers will build stunning original hacks and it can be a tough ask to keep working for such a long period. You can’t be sure that it won’t just be another “recipe app” or “Uber for X”.

This is the second session, which I gave at Red Hat Summit; this was an exploration of what is behind the reactive trend. Software is fiction, every season we have a new collection, we all have to follow this and right now, it’s reactive.

Managing the security of your projects applications can be an overwhelming and unmanageable task. In today’s world, the number of newly created frameworks and languages is continuing to increase and they each have their own security drawbacks associated with them.
The wide variety of security scanners available can help find vulnerabilities in your projects, but some scanners only work with certain languages and they each have different reporting output formats. Creating reports for customers or managers and viewing analytics using different security tools in different projects can be a very time-consuming task.
