We’ve all been frustrated by latency, either as users of an application, or as developers building such apps.
At ScyllaDB‘s annual Pekka Enberg, founder and CTO of shared his favorite tips for spotting and removing latency from systems.
“Latency lurks everywhere,” said Enberg, who also has authored a once estimated that it loses 1% of sales for every 100ms of latency.

Enberg has thought plenty about ways of reducing latency and has boiled down his solutions into three different approaches:

The keepers of the internet standards are Internet Architecture Board (IAB), a group of theThe Next Era of Network Management Operations (NEMOPS) workshop, to compile a list of technologies that might be useful for an internet of the future.
They did this before, RFC 6241), the Network Configuration protocol, now widely-used to install, manipulate, and delete the configuration of network devices.

It was in 2022 when Meta engineers started to see the first clouds of an incoming storm, namely how much AI would change the nature —and volume — of the company’s network traffic.
“Starting 2022, we started seeing a whole other picture,” said Meta’s Networking @Scale 2024 conference, being held this week both virtually and at Santa Clara Convention Center, in Calif.
Mind you, Meta owns one of the world’s largest private backbones, a global network physically connecting 25 data centers and 85 points of presence with millions of miles of fiber optic cable, buried under both land and sea. Its reach and throughput allows someone on an Australian beach to see videos being posted by their friend in Greece nearly instantaneously.
And for the past five years, this global capacity has grown consistently by 30% a year.
Yet, the growing AI demands on the backbone is bumpy and difficult to predict.
“The impact of large clusters, GenAI, and AGI is yet to be learned,” Sundaresan said. “We haven’t yet fully flushed out what that means for the backend.”
Nonetheless, the networking team has gotten creative Continue reading
Tired of dealing with cloud providers and mulling a move to a private cloud instead? Broadcom wants you to take a look at its operation of a private cloud.
This week at Paul Turner, Broadcom vice president of products for VCF, in a press briefing.
Broadcom is positioning VCF as a lower-cost, more secure alternative to public cloud computing.
Overall, the goal is to help the organization create an infrastructure that works together as a single, unified whole while supporting modern application architectures.

According to the company, a private cloud approach can result in:

The Istio service mesh software offers a potentially big change in how to handle Kubernetes traffic, with the introduction of an ambient mesh option.
Although the technology has been offered as an experimental feature for several releases, the core development team taking feedback from users, this is the first release to offer the feature as a production-grade capability.
It’s a new architecture entirely, explained Solo.io, as well as a member of Idit Levine, founder and CEO of Solo.io. Once applications are decomposed into individual services, these services require a way to communicate. Hence it made sense to festoon each Continue reading
SEATTLE–By the time he finished his Peace Lee got three (3!) separate rounds of applause from the audience.
The Linux greybeards in attendance were impressed with the program, that he wrote the program himself (over a period of nine years) and that he did so without any help from system libraries.

No doubt, countless engineers and hackers remember the first time they used newly-developed microscope to view cells for the first time ever: What was once just an inscrutable package had opened up to reveal a treasure trove of useful information.
This year, the venerable Wireshark has turned 25, and its creators are taking a step back from this massively successful open source project, to let additional parties to help govern. This month, Sysdig, the current sponsor of Wireshark, launched a new foundation that will serve as the long-term custodian of the project. The
Malware is sneaky AF. It tries to hide itself and cover up its actions. It detects when it is being studied in a virtual sandbox, and so it sits still to evade detection. But when it senses a less secure environment — such as an unpatched Windows 7 box — it goes wild, as if Tudor Dumitras, in a recently posted talk from red pills, which helps malware detect when it is in a controlled environment, and change its behavior accordingly.
As a result, many of the signatures used for commercial malware detection packages may not Continue reading
The internet as we know it may no longer be a thing, warns a European Union-funded researcher. If it continues to fray, our favorite “network of networks” will just go back to being a bunch of networks again. And it will be the fault of us all.

A Go Router reverse proxy removes headers that would let a CF application know it can send and receive HTTP/2 traffic. Such capability could be coded in, bypassing the Go language library entirely, but the project team doesn’t want to take on the responsibility for supporting such a potentially widely-used function.

With the newest edition of the gRPC protocol, Microservices-based systems will no longer need separate stand-alone service mesh sidecars, noted Envoy, one of the most popular sidecar proxies in use today.

If you are going to use a service mesh to manage a set of microservices, you might as well start thinking of the service mesh as the “security kernel” for these distributed systems, suggested Tetrate Senior Engineer U.S. National Institute of Standards and Technology (NIST) and Tetrate, a purveyor of an

“I remember the fear that the huge event we were experiencing could bring our platform down,” said recalled at HAProxy 2019. They kept watching the Grafana dashboard, searching for potential anomalies.
In the end, however, nothing bad happened. “We ended up drinking beers and eating pizzas,” he said. But Gallissot didn’t want to go through such a stressful experience again, and so started an initiative to move M6 to the cloud.
Like many organizations dealing with surges of traffic, M6 decided on Kubernetes as the platform for a multicloud architecture, to ease the process of easily scaling up and down traffic. And one of the most crucial parts of the Kubernetes setup is routing the incoming traffic to the appropriate services.
Kubernetes itself offers an option to capture the
Welcome to The New Stack Context, a podcast where we discuss the latest news and perspectives in the world of cloud native computing. For this week’s episode, we spoke with The New Stack correspondent Jennifer Riggins about all of the reporting she and others on the TNS team have been doing recently on the effects that the COVID-19 global pandemic is having on the tech industry.
TNS editorial and marketing director Libby Clark hosted this episode, alongside founder and TNS publisher Alex Williams and TNS managing editor Joab Jackson.

For this episode, we wanted to look at and not only discuss the changing patterns in network traffic that the global COVID-19 pandemic has wrought, due to factors such as people staying at home and working from home, and the sudden acceleration of e-learning. As Riggins writes in a recent post:
For a lot of tech and infrastructure teams, they not only are going through the stress of the collective trauma we’re sharing in, but they are struggling to keep up with ever-scaling, extreme strains on their systems. Simply put, Continue reading
Dragonfly, a peer-to-peer image and file-sharing technology developed by Cloud Native Computing Foundation. The software provides a way to quickly distribute images across large cloud native deployments, eliminating the dependency on a single registry to distribute all the copies of an image.
“Dragonfly is one of the backbone technologies for container platforms within Alibaba’s ecosystem, supporting billions of application deliveries each year, and in use by many enterprise customers around the world,” said Dragonfly in 2015, originally to ease file distribution. By 2017, when it was adopted to share containers within Kubernetes environments, it was being used by the Chinese cloud service to share 3.4PB each month. It was originally accepted into the OCI (Open Container Initiative). It can work with CNCF’s Prometheus and display them on a Helm can be used to install Dragonfly within a Kubernetes cluster.
Project maintainers come from Alibaba, ByteDance, eBay, and Meitu. Overall it has 67 contributors from 21 organizations. It has been downloaded over 100,000 times from Docker Hub and has massed 6,000 GitHub stars.
