We’ve encountered VM connectivity issues after VM movements from one vPC leaf pair to a different vPC leaf pair with ACI. The issue did not occur immediately (due to ACI’s bounce entries) and only sometimes, which made it very difficult to reproduce synthetically, but due to DRS and a large number of VMs it occurred frequently enough, that it was a serious problem for us.

By: Eve-Marie Lanza, Senior Security Solutions Marketing Manager, HPE Aruba Networking.An advertising campaign from the 1980s posited that peanut butter and chocolate were, “two great tastes that taste great together.” While confectionary tastes may vary, there’s no denying that some things just work better together. When it comes to IT security, network access control, and Zero Trust security are like peanut butter and chocolate—great on their own, undeniably better together.Network access control vs. Zero Trust securityNetwork access control and Zero Trust security are not the same, but they are related.To read this article in full, please click here
The interesting thing about the June 2023 rankings of the world’s most powerful supercomputers is not how it really has not changed all that much in the past six months, or that the June list is coming out in May. …
Although the popular adoption of the public cloud hasn’t killed network security, it does require an approach different from traditional data center security.
The FCC’s latest spectrum policy announcement, which preserves 500MHz of the 12GHz band for satellite use while designating another 500MHz for terrestrial radios, is a recognition that satellite internet providers like Starlink are being heard, according to experts.The commission’s latest notice of proposed rulemaking, posted May 18, reflects a more even-handed approach than has been adopted in the past. In carving up the airwaves for C-band usage, substantial amounts of spectrum were taken away from incumbent satellite users and handed off to terrestrial operators, most notably major telecom providers.To read this article in full, please click here
You’d be hard pressed to find another technology that has been as useful, successful, and ultimately influential as Ethernet, and as it celebrates its 50th anniversary this week, it is clear that Ethernet’s journey is far from over.Since its invention by Bob Metcalf and David Boggs back in 1973, Ethernet has continuously been expanded and adapted to become the go-to Layer 2 protocol in computer networking across industries.To read this article in full, please click here
Today on the Tech Bytes podcast we speak with sponsor Pica8 about how whitebox networking gives engineers the flexibility to choose the hardware and software that best meets their campus needs. Because Pica8’s network OS can run on multiple hardware platforms, engineers can overcome challenges including supply chain disruptions, end-of-life hardware, and security events.

5G promises increased speed, lower latency, and support for a significantly larger number of connected devices. But the growth in devices and in new applications that will ensue also will expand the attack surface, offering new opportunities for malicious actors to take advantage of security gaps.Plus, as with any new technology, there is a great deal of potential for misconfigurations, errors, and unpatched vulnerabilities while companies are still learning how to deploy and secure 5G at scale.About 75% of communication service providers worldwide said that they had experienced up to six security breaches of 5G networks within the past year, according to a November 2022 survey by GlobalData and Nokia. Half of the respondents said that they experienced an attack that resulted in the leakage of customer data, and nearly three quarters said that an attack had caused a service outage.To read this article in full, please click here
Developer Week 2023 is officially a wrap. Last week, we shipped 34 posts highlighting what has been going on with our developer platform and where we’re headed in the future – including new products & features, in-depth tutorials to help you get started, and customer stories to inspire you.
We’ve loved already hearing feedback from you all about what we’ve shipped:
🤯 Serverless machine learning deployments - OMG! We used to need a team of devops to deploy a todo list MVP, it’s now 3 clicks with workers. They’re gonna do the same with ML workloads. Just like that. Boom. https://t.co/AcKUQ79fv0
Love this direction, for open source, for demos and running things on edge.
It's still in development, but as someone who've built an AI product on top of Cloudflare and has been asking for something like this, I'm really excited! https://t.co/AnywRDqecb
In 2018, we first launched our Open Source Software Sponsorships program, and since then, we've been listening to your feedback, and realized that it's time to introduce a fresh and enhanced version of the program that's more inclusive and better addresses the needs of the OSS community.
A subset of open source projects on Cloudflare. See more >>
Previously, our sponsorship focused on engineering tools, but we're excited to announce that we've now opened it to include any non-profit and open source projects.
Program criteria and eligibility
To qualify for our Open Source Sponsorship Program, projects must be open source and meet the following criteria:
We launched the $2B Workers Launchpad Funding Program in late 2022 to help support the over one million developers building on Cloudflare’s Developer Platform, many of which are startups leveraging Cloudflare to ship faster, scale more efficiently, and accelerate their growth.
Cohort #1 wrap-up
Since announcing the program just a few months ago, we have welcomed 25 startups from all around the world into our inaugural cohort and recently wrapped up the program with the Demo Day. Cohort #1 gathered weekly for Office Hours with our Solutions Architects for technical advice and the Founders Bootcamp, where they spent time with Cloudflare leadership, preview upcoming products with our Developer Platform Product Managers, and receive advice on a wide range of topics such as how to build Sales teams and think about the right pricing model for your product.
Learn more about what these companies are building and what they’ve been up to below:
Why they chose Cloudflare “Cloudflare is the de facto Infrastructure for building resilient serverless products, it was a no-brainer to migrate to Cloudflare Workers to build the most frictionless experience for our customers.”
When your enterprise network begins showing signs of age, it's time for an upgrade. Learn how to handle the task with minimal frustration and disruption.
New year, new role, new strategy…2023 is officially the year when I return to my roots. Back in 2014, I officially became part of the Ansible community. Admittingly, back then my focus was solely on figuring out how to best demonstrate to my customers the power of having a OpenStack private cloud. Anyone who has ever stood up or experimented with OpenStack knows that this is a tall order. Imagine having to stand up that platform over and over again on a daily basis. My focus was to find a way—a tool—that could help me do that, so I could focus on helping solve the customers' true challenges. Fast forward to now, and the decision to do it with Ansible still stands as the best choice hands down.
Many of you have stories just like mine. You are seeking out a way to simplify your daily tasks, so you can focus on the business. Just like me, you have decided that Ansible is the tool to do it. Before I started in this new role, I did some reflecting on my experience as part of the community. I have so many encouraging, positive, and fun stories I could share. Our Continue reading
For the third time in a row, Frontier is ranked number one among the world’s fastest supercomputers, and it remains the only whose fastest speed exceeds one exaFLOPS.At 1.194 quintillion floating point operations per second (FLOPS), Frontier kept its ranking with more than double the top speed of its nearest competitor, according to the list compiled by TOP500, which issues the rankings twice a year. A quintillion is 1018 or one exaFLOPS (EFLOPS).The number two machine, Fugaku, maxed out at 442.01petaFLOPS. A petaFLOPS is 1015 FLOPS.Two competitors in the top 10 improved their speeds since the last ranking period that ended in November 2022, but not nearly enough to even draw close. Those two—LUMI and Leonardo—rank third and fourth, respectively.To read this article in full, please click here
