Jago Macleod reposted thisJago Macleod reposted thisOSS maintainers are overloaded at the moment with vulnerability reports. I got together with some other CNCF maintainers (Kubernetes, containerd), CNCF Security TAG, Google Project Zero bug finders, and Google's Vulnerability Reward Program folks to produce some advice specifically for OSS maintainers. It covers some advice on how to attack the problem at all stages of finding and fixing vulnerabilities. We also cover what we'd like to see from folks who are using AI to find and report vulns. Thanks to the Cloud Native Computing Foundation (CNCF) and OSS security brainstrust that contributed to this advice: Brandt Keller, Chris Aniszczyk, Evan Anderson, Ivan Fratric, Jordan Liggitt, Michael Lieberman, Monis Khan, Natalie Silvanovich, Rita Zhang, Sam Erb, Samuel Karp https://lnkd.in/gJv7_anJThe AI-driven shift in vulnerability discovery: What maintainers and bug finders need to knowThe AI-driven shift in vulnerability discovery: What maintainers and bug finders need to know

Jago Macleod shared thisThis was so much fun as always. Thank you Savannah Peterson for a great conversation!Jago Macleod shared thisGoogle’s collaboration with NVIDIA, Intel Corporation & Arm on AI-driven enhancements in Kubernetes 🚀 Join #theCUBE’s host Savannah Peterson at #KubeConNA 2025, as she gathers first-hand insights into some fun Kubernetes enhancements from Google Cloud’s Jago Macleod, Director Of Engineering, Kubernetes, and Gari Singh, Product Manager, along with Kate Holterhoff, Ph.D., Senior Industry Analyst at RedMonk. “The hardware has gotten fun again recently with ARM and all the CPUs that are doing interesting things. Now, we've been working a lot with Intel, NVIDIA and others on using some of the mechanisms in Kubernetes so that folks can squeeze that last bit of performance out of it. The DRA, Dynamic Resource Allocation, has now gone GA, and of course the AI workloads are the real motivating factor, but it inspired a lot of cool conversations with the SchedMD folks behind Slurm,” “I've been pleased with the collaboration with both the SchedMD folks on Slurm and the Anyscale folks on Ray. These communities are working well together. But the HPC world has 20 years of experience doing these very low-level interactions with the CPU, and they think it's madness that we just let the Linux scheduler figure out where to put a workload on a node with 300 cores. We've been improving the performance of all of those things on top of Kubernetes, and it's awesome to see,” he adds. 💡 Get more insights! https://lnkd.in/dzy4Ffdc #GKE #Kubernetes #Inference #CloudNative

Jago Macleod reposted thisJago Macleod reposted thisFor the last five years, Google's Open Source Programs Office has published a report of the company's work and contributions to open source. Out today is the 2023 report. Last year, "roughly 10% of Alphabet's full-time workforce actively contributed to open source projects. This percentage has remained roughly consistent over the last five years." This is a stat I'm really proud of. This isn't just engineering, this is 10% of everyone. It's a number that wouldn't happen without the incredible work of my OSS colleagues and the Googlers who use open source to do their jobs more effectively, to be creative and explore, and to support our technology commons. https://lnkd.in/ge3zwC_y

Checked that box! Argentina ranks #2 in CNCF contributors in all Latin America, that's huge! #nerdearla was huge, 5 days with a flowing river of people filling out the Ciudad Cultural Konex, legendary speakers, and great old friends. Thank you #Nerdearla, until next time! Ariel Jolo Kass Dhillon Patricia Bautista Cruz José Sahad #CNCF #OSPO #Kubernetes #GKE

Jago Macleod liked thisJago Macleod liked thisSuper Thankful for Forrester and their recognition of our products and services this quarter. We talk about the the difference of Google Cloud's AI strategy be foundationally different. Being unique and providing AI optionality at all levels like the competition, but differentiate by also providing a Full Stack of ADULT ENTERPRISE grade solutions from Chips to Data, to security, to Models. This is not only better for customer choice, it just makes us better at all things AI, and continues to separate us going forward. Tech matters, services matter, approach matters (FDEs), in this nuclear paced AI race. Off we go, more to come. 🚀 🚀 🚀 Google, #ai, #LLMs, #Data, #GenAI, #technology

Jago Macleod liked thisJago Macleod liked thisWe all know Reinforcement Learning (RL) is incredibly expensive. But we want to make it economically viable for everyone by stripping out the massive infrastructure inefficiencies that keep accelerators idle. That's why we're so proud of our latest work on time-slicing for RL. We've proven that you can run multiple complex workloads on a fraction of the hardware without any compromise on model performance. We just published a deep dive on how we multiplexed three different RL and SFT workloads onto just two shared GPUs—resulting in up to 67% reduction in physical hardware footprint and ~40% savings in GPU-hours. Check out the full benchmark and technical breakdown on our blog:👉 https://lnkd.in/gBnrnUtZ Stay tuned, we will be publishing a number of interesting recipes that you can use - Interleaving batch inference with RL job - Interleaving a co-located RL job with itself - Reliability and scale DM me if you want to discuss more or join llm-d if you want to collaborate.

Jago Macleod liked thisKubernetes minor version rollbacks! What once seemed impossible, we made it possible. Great article!

I'm on day 3 of writing every day for the next 7 days about useful GKE features that have recently launched Upgrading Kubernetes control planes across minor versions has always been a high-stakes, one-way street. Once you upgrade the API server binary, storage schemas change immediately, making downgrades impossible without restoring from etcd backups. The GKE team recently announced the General Availability of two-step control plane upgrades and minor version rollbacks across all release channels. By decoupling the binary rollout from API finalization, GKE runs the new binary in an emulated compatibility mode. This creates a safe observation period where health signals are monitored via canary analysis. If any regression occurs, you can roll back to the previous minor version with zero data loss. Auto-upgrades handle this staging automatically, while platform teams managing manual workflows get full support in gcloud and Terraform. I wrote a breakdown explaining how emulated mode works under the hood, how canary checks safeguard rollouts, and how to trigger rollbacks.

Jago Macleod liked thisJago Macleod liked this¡Estoy muy feliz que finalmente voy a estar presentando en mi país y en mi idioma en https://lnkd.in/gux7wwfC ! Este Septiembre próximo voy a ser parte de #Nerdearla Argentina 2026 (https://lnkd.in/gjigWGv5) y voy a cumplir un sueño de poder contar todos los avances y planes que estamos trabajando en el mundo de infraestructura para AI, alrededor de orquestación, #Kubernetes y #OpenSource. Gracias a #GoogleCloud, #OSPO y Kass Dhillon, #GKE y Jago Macleod por el soporte, y a Ariel Jolo y equipo por organizar #Nerdearla2026. PD: Cuando me ha tocado hablar en otro idioma, suelo hacer el chiste de: "si supieras lo inteligente que sueno cuando hablo en español...", vamos a ver si ahora puedo hacerlo realidad. PD2: Y la semana siguiente voy a estar haciendo un hands on workshop sobre agentes AI corriendo código inseguro en sandboxes seguros en #KCD Buenos Aires, pero dejo esto para el próximo post. ------------------------------------------------------------------- I’m truly thrilled to finally be presenting in my home country and in my native language at https://lnkd.in/gux7wwfC! 🇦🇷 This coming September, I'll be speaking at #Nerdearla Argentina 2026 (https://lnkd.in/gjigWGv5), fulfilling a longtime dream of sharing all the progress and plans we are working on in the AI infrastructure space—spanning orchestration, #Kubernetes, and #OpenSource. A huge thank-you to #GoogleCloud, #OSPO and Kass Dhillon, #GKE and Jago Macleod for all the support, and to Ariel Jolo and the entire team for organizing #Nerdearla2026. PS: Whenever I speak in another language, I usually joke: "If you only knew how smart I sound in Spanish..." Let's see if I can actually live up to it this time! 😉 PS 2: And the following week, I’ll be running a hands-on workshop on AI agents executing untrusted code within secure sandboxes at #KCD Buenos Aires—more on that in an upcoming post!
