IPv6 security-focused presentations were usually an awesome opportunity to lean back and enjoy another round of whack-a-mole, often starting with an attacker using IPv6 Router Advertisements to divert traffic (see also: getting bored at Brussels airport) .
Tackling the challenge of providing fast, smooth, jitter-free gameplay with super low end-to-end latency, social media giant in a blog post Thursday.
This low-latency gaming platform could also serve as the base Meta’s pending Metaverse, they asserted.
Facebook launched its cloud gaming platform in 2020, providing users quick access to native Android and Windows mobile games across all the browsers. Along with high a volume of consumer access came a high volume of developer and engineering challenges.
Network, Hosting, and Cluster Management
The first step Meta took in providing low end-to-end latency was a physical one — to reduce the distance between the cloud gaming infrastructure and the players themselves. For this Meta used edge computing and deployed in edges that were close to large populations of players. The goal of edge computing is to “have a unified hosting environment to make sure we can run as many games as possible as smoothly as possible,” Meta engineers Xiaoxing Zhu wrote.
The more edge computing sites, the lower the user latency.

Project Calico has offered a production-ready data plane based on eBPF since September 2020, and it’s been available for technical evaluation for even longer (since February 2020).
You do know what those are, don’t you? Don’t worry if not! That’s what this blog post is about. We’ve reached a point where the journey is easy to make, if you know why you want to get there.
Key advantages of using Calico with eBPF
Calico is already the most widely deployed Kubernetes network security solution. What can eBPF do to help our winning formula further? I’ll dive into the details, but let’s look at the highest possible level first.
These three key benefits apply across all supported environments:
General performance
Native Kubernetes service handling
Source IP preservation and Direct Server Return, or DSR
Each of these benefits is significant and worth discussing in more detail.
Performance
Calico’s eBPF data plane achieves high performance in several ways. Firstly, it achieves higher throughput and/or less CPU Continue reading
Amazon Web Services has officially opened its mainframe-migration service that promises to help Big Iron customers move apps to the cloud.AWS Mainframe Modernization, which since last November had been in preview, is available now and offers the tools, infrastructure, and software to manage migration of mainframe applications to the cloud, AWS stated.

The service includes tools to refactor workloads written for mainframes in legacy programming languages such as COBOL to Java-based cloud services. Or customers can keep their workloads as written and re-platform them to AWS with minimal code changes, AWS stated.To read this article in full, please click here

“I declare before you all that my whole life, whether it be long or short, shall be devoted to your service and the service of our great imperial family to which we all belong.” — Queen Elizabeth II birthday speech, April 21, 1947
When Elizabeth II's reign started, on February 6, 1952 (the coronation was on June 2, 1953), the Turing machine had already been proposed (1936), and with that the basis for computer science. ARPANET, which became the technical foundation of the Internet, was still a dream that came to fruition in the late 60s — the World Wide Web is from 1989 and in 2014 we celebrated its Silver Jubilee. So, with that in mind, let’s answer the question: did the 2022 celebrations of the first British monarch with a 70th anniversary on the throne have an impact on the UK’s Internet traffic?

In the world of automation and agility, it seems that Information Technology Infrastructure Library (ITIL) doesn’t have a role to play anymore, being marked as an “old school” framework. Can it be the end of the methodology after it served numerous IT organizations for so long as a guideline and blueprint for their processes?
This series of articles shows how automation, and more specifically Red Hat Ansible Automation Platform and the principles of Infrastructure as Code (IaC), can help bring some of the ITIL topics into the agile and automated bliss:
Configuration management
Change and release management
Incident and problem management
So let’s step into the topic of configuration management and what everybody still knows as CMDB (Configuration Management Database) even if ITIL has since long titled it as CMS (Configuration Management System). This name change was meant to highlight the fact that the function can be fulfilled by a combination of multiple databases and tools, but it won’t matter here, so we’ll stick to the infamous CMDB term.
Do you love your CMDB? Probably not, according to my experience with numerous customers. The data is generally outdated and wrong, considered useless, which means that its maintenance is considered a Continue reading
Each anniversary of Project Galileo serves as an impetus for big-picture thinking among the Cloudflare team about where to take the initiative next. For this eighth anniversary, we want to help participants get the most out of their free security and performance services and simplify the onboarding process.
Organizations protected under Galileo are a diverse bunch, with 111 countries represented across 1,900+ web domains. Some of these organizations are very small and sometimes operated solely by volunteers. It is understandable that many do not have IT specialists or other employees with technical knowledge about security and performance capabilities. We strive to give them the tools and training to succeed, and we felt it was imperative to take this effort to a new level.
Introducing the Cloudflare Social Impact Projects Portal
To provide Galileo participants with one place to access resources, configuration tips, product explainers, and more, we built the Cloudflare Social Impact Projects Portal.
The crisis in Ukraine was a key source of inspiration for this endeavor. With overall applications for the project skyrocketing by 177% in March 2022, we were rushing to onboard new Continue reading

While it's one of the best tools for examining performance on Linux, htop still requires some explanation before you'll be ready to take advantage of all the data it displays. It’s an excellent tool, but you need to understand the coloring scheme, how to scroll up and down through the processes displayed, and how to change your view of what’s happening on the system.It may take some time to get used to the type of information shown and be ready to quickly notice performance problems. That, of course, means that you have to know what normal behavior looks like on your system, and this generally requires spending time with the tool on a relatively frequent basis. In other words, use htop when you’re not at all concerned about how your system is performing and you’ll likely be able to make good use of it when you are.To read this article in full, please click here

A friend of mine started using Vagrant with libvirt years ago (it was his enthusiasm that piqued my interest in this particular setup, eventually resulting in netlab). Not surprisingly, he’s built Vagrant boxes for any device he ever encountered, created quite a collection that way, and would like to use them with netlab.
While I didn’t think about this particular use case when programming the netlab virtualization provider interface, I decided very early on that:
Everything worth changing will be specified in the system defaults
You will be able to change system defaults in topology file or user defaults.
