Intel Downplays Hybrid CPU-GPU Engines, Merges NNP Into GPU
When Intel announced its “Falcon Shores” project to build a hybrid CPU-GPU compute engine back in February 2022 that allowed the independent scaling of CPU and GPU capacity within a single socket, it looked like the chip maker was preparing to take on rivals Nvidia and AMD head on with hybrid compute motors, which Intel calls XPUs, AMD calls APUs, and Nvidia doesn’t really have if you want to be strict about what its “superchips” are and what they are not. …

Ansible for Disaster Recovery
Overview
When we get into the nuts and bolts of implementing a disaster recovery (DR) plan, an important step is to evaluate the tech stack that’s hosting the critical applications. The techstack oftentimes determines the order of operations and execution needed to effect the DR. Most organizations have the following tech stack pattern for their data centers:
Each of these layers has their own SMEs (Subject Matter Experts) who will need to work in tandem to address complexities and challenges during a DR event, and create a plan to ensure business continuity.
Challenges in creating a disaster recovery plan
“Everybody has a plan until they get punched in the face.” - Mike Tyson
Cyber attacks, natural disasters, human error, server failure–any number of potential events can bring on the need for disaster recovery. While the risk of experiencing a disaster event won’t go away, the negative impact of such an event can be drastically minimized with the right planning.
The following is a sample SOP to recover an application during a disaster. Depending on the needs of the organization, DR procedures could be simpler or more complex than the examples shown here. After monitoring systems have detected conditions Continue reading
SASE Implementation: Five Steps to Take Before You Go Live
SASE can fill in your edge security needs, but implementing SASE requires planning and coordination.Cloudflare Area 1 earns SOC 2 report
Cloudflare Area 1 is a cloud-native email security service that identifies and blocks attacks before they hit user inboxes, enabling more effective protection against spear phishing, Business Email Compromise (BEC), and other advanced threats. Cloudflare Area 1 is part of the Cloudflare Zero Trust platform and an essential component of a modern security and compliance strategy, helping organizations to reduce their attackers surface, detect and respond to threats faster, and improve compliance with industry regulations and security standards.
This announcement is another step in our commitment to remaining strong in our security posture.
Our SOC 2 Journey
Many customers want assurance that the sensitive information they send to us can be kept safe. One of the best ways to provide this assurance is a SOC 2 Type II report. We decided to obtain the report as it is the best way for us to demonstrate the controls we have in place to keep Cloudflare Area 1 and its infrastructure secure and available.
Cloudflare Area 1’s SOC 2 Type II report covers a 3 month period from 1 January 2023 to 31 March 2023. Our auditors assessed the operating effectiveness of the 70 controls we’ve implemented to meet the Continue reading
Are LACP Fast Timers Any Good?
Got this question from a networking engineer attending the Building Next-Generation Data Center online course:
Has anyone an advice on LACP fast rate? When and why should you use it instead of normal LACP?
Apart from forming link aggregation groups, you can use LACP to detect link- and node failures (more details). However:

Talking Novel Architectures And El Capitan With Lawrence Livermore
The HPC gurus of the world may have started moving into the hyperscalers and cloud builders in recent years, but they don’t tend to work for vendors and they tend to stay in one place and lean in. …

DNS observability and troubleshooting for Kubernetes and containers with Calico
In Kubernetes, the Domain Name System (DNS) plays a crucial role in enabling service discovery for pods to locate and communicate with other services within the cluster. This function is essential for managing the dynamic nature of Kubernetes environments and ensuring that applications can operate seamlessly. For organizations migrating their workloads to Kubernetes, it’s also important to establish connectivity with services outside the cluster. To accomplish this, DNS is also used to resolve external service names to their corresponding IP addresses. The DNS functionality in Kubernetes is typically implemented using a set of core-dns pods that are exposed as a service called kube-dns. The DNS resolvers for workload pods are automatically configured to forward queries to the kube-dns service.
The output below shows the implementation of the kube-dns services in a Kubernetes cluster.
kubectl get service kube-dns -n kube-system NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) kube-dns ClusterIP 10.0.0.10 <none> 53/UDP,53/TCP
The core-dns pods have to rely on external DNS servers to perform domain name resolution for services outside the cluster. By default, the pods are configured to forward DNS queries to the DNS server configured in the underlying host in the /etc/resolv.conf file. The output below displays Continue reading

Is Your 5G Service Slow? Join the Club
Median 5G performance is declining globally in many early launch 5G markets. Here is a look at why and what might be done to address the issue.Understand the impact of Waiting Room settings with Waiting Room Analytics
In January 2021, we gave you a behind-the-scenes look at how we built Waiting Room on Cloudflare’s Durable Objects. Today, we are thrilled to announce the launch of Waiting Room Analytics and tell you more about how we built this feature. Waiting Room Analytics offers insights into end-user experience and provides visualizations of your waiting room traffic. These new metrics enable you to make well-informed configuration decisions, ensuring an optimal end-user experience while protecting your site from overwhelming traffic spikes.
If you’ve ever bought tickets for a popular concert online you’ll likely have been put in a virtual queue. That’s what Waiting Room provides. It keeps your site up and running in the face of overwhelming traffic surges. Waiting Room sends excess visitors to a customizable virtual waiting room and admits them to your site as spots become available.
While customers have come to rely on the protection Waiting Room provides against traffic surges, they have faced challenges analyzing their waiting room’s performance and impact on end-user flow. Without feedback about waiting room traffic as it relates to waiting room settings, it was challenging to make Waiting Room configuration decisions.
Up until now, customers could only monitor their waiting room's Continue reading
Distributed Systems Resources
Distributed systems are complicated. Add networking to the mix, and you get traumatic challenges like the CAP theorem and Byzantine fault tolerance. Most of those challenges are unknown to engineers who have to suffer through the vendor marketing presentations, making it hard to determine whether the latest shiny gizmo works outside of PowerPoint.
I started collecting articles describing distributed-system gotchas years ago, wrote numerous blog posts on the topic in the heydays of the SDN Will Save the World lemming run, and organized them into the Distributed Systems Resources page.
