Google Cloud can tie together enterprise multicloud resources

Google Cloud has announced services for enterprises to more easily and securely connect distributed multicloud resources.The chief service, Cross-Cloud Interconnect, provides dedicated high-speed connections between the Google network and customer networks hosted in other clouds—Amazon Web Services, Microsoft Azure, Oracle Cloud Infrastructure, or Alibaba.“Cross-Cloud Interconnect lets organizations connect to any public cloud through a highly secure, dedicated-bandwidth network that has a much lower latency than going through an internet-based VPN solution,” said Muninder Sambi, vice president and general manager of networking for Google Cloud. “With the new service, customers can run their applications on multiple clouds, they can host SaaS applications that are multicloud, and they can also migrate workloads from one cloud to another.”To read this article in full, please click here

Intel looking likely to manufacture Nvidia chips

More than a year ago, Nvidia CEO Jensen Huang said he was open to the possibility of having Intel manufacture Nvidia’s GPUs through Intel's foundry services program.At the time, Huang was noncommittal beyond saying that Nvidia was looking at the possibility. Now things are getting more concrete. During a question-and-answer session at the Computex tradeshow in Taipei, Taiwan, Huang said he had recently received good results for an Intel test chip based on the company's next-generation process node."You know that we also manufacture with Samsung, and we're open to manufacturing with Intel. [Intel CEO Pat Gelsinger] has said in the past that we're evaluating the process, and we recently received the test chip results of their next-generation process, and the results look good," Huang said.To read this article in full, please click here

Writing An IETF Draft: Document Streams And Document Status

So far in this series we’ve discussed the history of the IETF, some of the tools you might want to use when building an IETF submission, and document formatting. There are other seemingly mystical concepts in the IETF process as well—for instance, what is a “document stream,” and what is a document’s “status?” Let’s look […]

6 lessons from the Amazon Prime Video serverless vs. monolith flap

A software-development team caused quite a stir recently with a blog post describing how it abandoned a serverless architecture project in favor of a monolith—and slashed cloud infrastructure costs by 90% in the process.But this wasn’t just any team; the post was written by Marcin Kolny, a senior software-development engineer at Amazon Prime Video.Since Amazon is one of the leading advocates for serverless computing, not to mention the market leader in cloud services, the post was viewed as either a commendable act of openness or the very definition of throwing your company under the bus. Either way, it triggered a passionate back and forth on social media platforms that focused on larger questions:To read this article in full, please click here

Day Two Cloud 197: Understanding Decentralized Identity With Dr. Joanne Friedman

On today's Day Two Cloud we dive into Decentralized Identity, or DID. This W3C standard is a unique identifier, authenticated by cryptographic proofs, that individuals and organizations can generate themselves using systems they trust. A DID can be a person, an object, an organization, a data model, or other subject. We explore DIDs, how they work, and what they can be used for with Dr. Joanne Friedman.

NTP in a Nutshell

Years ago I’ve been involved in an interesting discussion focusing on NTP authentication and whether you can actually implement it reliably on Cisco IOS. What I got out of it (apart from a working example) was the feeling that NTP and it’s implementation in Cisco IOS was under-understood and under-documented, so I wrote an article about it. Of course the web version got lost in the mists of time but I keep my archives handy.

Last weekend I migrated that article to blog.ipSpace.net. I hope you’ll still find it useful; while it’s pretty old, the fundamentals haven’t changed in the meantime.

Heavy Wireless 003: Designing Eduroam For The Future With Mark Houtz

On today's Heavy Wireless, Keith Parsons talks with guest is Mark Houtz about designing Eduroam for the future, including the 6Ghz band. Mark explains the challenges of filtering Internet access for K-12 students when they travel outside of their local high school and the technical requirements of Eduroam, specifically the use of WPA3 Enterprise on all frequencies when using the new 6 GHz band. Mark also shares his testing process for Eduroam's compatibility with 6 GHz radios.

Network Break 432: DriveNets Aims To Make Ethernet AI-Friendly; China Goes Eye-For-An-Eye With US Over Tech Bans

This week we discuss a new offering from DriveNets that aims to make Ethernet more suitable as a network fabric for AI workloads, why the EU slapped Meta with a $1.3 billion fine, and a new offering from Extreme Networks that lets you manage Extreme gear in the cloud or from on-prem, China banning Micron, and more IT news.

Tech Bytes: Assembling A SASE Architecture With Fortinet (Sponsored)

Today on the Tech Bytes podcast we pull back the covers on SASE, or Secure Access Service Edge. Fortinet is our sponsor. One important concept to grasp around SASE is that it’s as much an architecture as it is a product. It requires planning and foresight to put the pieces together and operate them. We talk with Fortinet about the elements of its SASE offering and what a typical customer engagement with SASE looks like.

How doNotTrack policies work in the Calico eBPF dataplane

Almost all modern network systems, including stateful firewalls, make use of connection tracking (“conntrack”) because it consumes less processing power per packet and simplifies operations. However, there are use cases where connection tracking has a negative impact, as we described in Linux Conntrack: Why it breaks down and avoiding the problem. Distributed Denial of Service (DDoS) mitigation systems, defending against volumetric network attacks, is a well known example of such a use case, as it needs to drop malicious packets as fast as possible. In addition to these attacks, connection tracking becomes a potential attack vector as it is a limited resource. There are also applications generating huge amounts of short lived connections per second, to the point that tracking connections leads to more processing and defeating its intended purposes. These use cases demonstrate that there is a need to not track connections in a firewall, also known as stateless firewalling.

In this blog post, we will explain how Project Calico uses eXpress Data Path (XDP) in its eBPF dataplane (also in its iptables dataplane but not the focus of this post) to improve the performance of its stateless firewall. XDP is an eBPF hook that allows a program to Continue reading

MGX: Nvidia Standardizes Multi-Generation Server Designs
