Cloud Giants Collaborate on New Kubernetes Resource Management Tool

Google Cloud, AWS, and Microsoft Azure have jointly showcased a new open-source project called Kube Resource Orchestrator (kro, pronounced "crow"). The project is an attempt to standardise how Kubernetes resources are grouped together and deployed, and it aims to make it easier for platform teams to deploy workloads.

The announcement explains that Kubernetes lacks a native method for platform teams to create custom groups of resources that can be used by development teams, with many organisations using client-side templating tools like Helm or Kustomize, or building their own custom Kubernetes controllers. These approaches often proved costly to maintain and difficult for non-specialists to use effectively.

With kro, you can group your applications and their dependencies as a single resource that can be easily consumed by end consumers - Abdelfettah Sghiouar and Nic Slattery.

The core innovation of kro is the introduction of the ResourceGraphDefinition custom resource. kro encapsulates a Kubernetes deployment and its dependencies into a single API, enabling custom end-user interfaces that expose only the parameters applicable to a non-platform engineer. This masking hides the complexity of API endpoints for Kubernetes and cloud providers that are not useful in a deployment context.

The post outlines two practical examples of kro's application. In the first scenario, a platform engineer uses kro to give organisation members self-service access to create Google Kubernetes Engine (GKE) clusters with pre-configured administrative workloads, policies, and security settings. The second example demonstrates how DevOps engineers can create reusable definitions for web applications, encapsulating all necessary resources from deployments and services to monitoring agents and cloud storage.

Kro works seamlessly with the existing cloud provider Kubernetes extensions that are available to manage cloud resources from Kubernetes. These are AWS Controllers for Kubernetes (ACK), Google's Config Connector (KCC), and Azure Service Operator (ASO).

kro enables standardised, reusable service templates that promote consistency across different projects and environments, with the benefit of being entirely Kubernetes-native. It is still in the early stages of development. "As an early-stage project, kro is not yet ready for production use, but we still encourage you to test it out in your own Kubernetes development environments," the post states.

In a post on the AKS Engineering Blog, Bridget Kromhout and Matthew Christopher offer a brief overview of the kro project from Microsoft's perspective. This post emphasises Microsoft Azure's collaboration with AWS and Google Cloud on this Kubernetes-native tool designed to simplify resource management. Kromhout and Christopher also offer Azure-specific implementation examples and highlights opportunities for community involvement.

We're centering the needs of customers and the cloud native community to offer tooling that works seamlessly no matter where you run your K8s clusters - Matthew Christopher & Bridget Kromhout.

A walkthrough on the kro website goes under the hood to explain how kro works, explaining how kro creates a ResourceGraphDefinition by first generating a Directed Acyclic Graph (DAG) to understand the dependencies of a definition, validating them and establishing the correct deployment order. It then creates a new CustomResourceDefinition (CRD) in the Kubernetes cluster for the resources.

Some community commentary has pondered kro's ability to augment or replace other well-established tools, such as Crossplane - an open-source CNCF project that lets consumers orchestrate cloud resources with Kubernetes, and Helm, the package manager for defining, installing and upgrading Kubernetes applications.

In a YouTube video on the DevOps Toolkit channel, Viktor Farcic discusses kro's launch. He also considers its impact on Crossplane. Farcic was initially excited by kro's potential to simplify composing cloud resources, and he successfully created a simple application definition that generated correct Kubernetes resources. However, Farcic found that more complex scenarios involving conditional resource creation and database integration caused numerous issues, such as missing default values and owner references and changes from ResourceGroups not propagating properly to existing resources.

He also notes that using YAML for imperative constructs isn't ideal, and that adding more logic to a format not designed for it could lead to "abominations". Most significantly for the Crossplane community, Farcic questioned kro's purpose given its functional overlap with existing tools. "kro is serving more or less the same function as other tools created a while ago without any compelling improvement," he observed. While kro appeared to offer a simpler syntax with less boilerplate, he says it currently provides only a fraction of Crossplane's aspects and is not yet a viable replacement, especially as Crossplane supports multiple languages.

In a blog post pondering "Is the Helm Killer Finally Here?", Wilson Spearman of Parity indicates that Helm's architecture has fundamental constraints in managing dependencies, handling CRD upgrades and in properly managing lifecycles, and kro succeeds in having a more human-friendly and readable syntax. Spearman concludes with a prediction that Helm will continue for open-source and smaller organisations, with kro taking mindshare in the enterprise.

The kro project is available on GitHub under joint ownership by teams from Google, AWS, and Microsoft, with the community invited to contribute to its development. Comprehensive documentation and example use cases are available on the project's website.

DeepSeek - Recap

It was only a month ago that DeepSeek disrupted the AI world with its brilliant use of optimization and leveraging of the NVIDIA GPU's the team had to work with. The results were, and still are, revolutionary - not just because of what DeepSeek accomplished, but also because they released it to the world in the true spirit of open-source, so that everyone could benefit.

This is a cursory look at the technical aspects of what the team accomplished and how:

Artificial Intelligence has long been driven by raw computational power, with companies investing billions in larger, more powerful hardware to push the limits of AI capabilities. However, DeepSeek has disrupted this trend by taking an entirely different approach—one that emphasizes optimization over brute force. Their innovation, which allows them to train a 671-billion-parameter language model at speeds ten times faster than industry leaders like Meta, signals a fundamental shift in AI hardware utilization.

The Traditional Approach: CUDA and Standard GPU Processing.

For years, AI models have been trained using NVIDIA’s CUDA (Compute Unified Device Architecture), a parallel computing platform that allows developers to harness GPU power efficiently. CUDA provides a high-level programming interface to interact with the underlying GPU hardware, making it easier to execute AI training and inference tasks. However, while effective, CUDA operates at a relatively high level of abstraction, limiting how much fine-tuned control engineers have over GPU performance.

DeepSeek’s Revolutionary Strategy: The Shift to PTX.

DeepSeek has taken a different path by bypassing CUDA in favor of PTX (Parallel Thread Execution). PTX is a lower-level GPU programming language that allows developers to optimize hardware operations at a much finer granularity. By leveraging PTX, DeepSeek gained deeper control over GPU instructions, enabling more efficient execution of AI workloads. This move is akin to a master mechanic reconfiguring an engine at the component level rather than simply tuning its performance through traditional means.

Hardware Reconfiguration: Unlocking New Potential.

Beyond just software optimizations, DeepSeek reengineered the hardware itself. They modified NVIDIA’s H800 GPUs by repurposing 20 out of the 132 processing units solely for inter-server communication. This decision effectively created a high-speed data express lane, allowing information to flow between GPUs at unprecedented rates. As a result, AI training became vastly more efficient, reducing processing time and power consumption while maintaining model integrity.

One of the most striking aspects of DeepSeek’s innovation is the potential for cost reduction. Traditionally, training massive AI models requires extensive computational resources, often leading to expenses in the range of $10 billion. However, with DeepSeek’s optimizations, similar levels of training can now be achieved for just $2 billion—a staggering fivefold reduction in cost. This development could open the door for smaller AI startups and research institutions to compete with tech giants, leveling the playing field in AI innovation.

Industry Reactions and Market Disruptions.

DeepSeek’s breakthrough did not go unnoticed. Upon the announcement of their achievement, NVIDIA’s stock price took a significant dip as investors speculated that companies might reduce their reliance on expensive, high-powered GPUs. However, rather than being a threat to hardware manufacturers, DeepSeek’s advancements could signal a broader industry shift toward efficiency-focused AI development, potentially driving demand for new GPU architectures that emphasize custom optimizations over sheer processing power.

DeepSeek’s work challenges conventional thinking in AI hardware. Instead of simply increasing computational power, they have demonstrated that intelligent hardware and software optimizations can yield exponential performance improvements. Their success raises essential questions: What other untapped optimizations exist in AI hardware? How can smaller companies adopt similar efficiency-focused approaches? And will this paradigm shift eventually lead to an AI revolution driven by accessibility and affordability?

By redefining the way AI training is approached, DeepSeek has not only introduced a faster, cheaper, and more efficient methodology but also set the stage for a future where AI innovation is dictated not by who has the most powerful hardware, but by who can use it the smartest way.

Microsoft Releases BioEmu-1: A Deep Learning Model for Protein Structure Prediction

Microsoft Research has introduced BioEmu-1, a deep-learning model designed to predict the range of structural conformations that proteins can adopt. Unlike traditional methods that provide a single static structure, BioEmu-1 generates structural ensembles, offering a broader view of protein dynamics. This method may be especially beneficial for understanding protein functions and interactions, which are crucial in drug development and various fields of molecular biology.

One of the main challenges in studying protein flexibility is the computational cost of molecular dynamics (MD) simulations, which model protein motion over time. These simulations often require extensive processing power and can take years to complete for complex proteins. BioEmu-1 offers an alternative by generating thousands of protein structures per hour on a single GPU, making it 10,000 to 100,000 times more computationally efficient than conventional MD simulations.

BioEmu-1 was trained on three types of datasets: AlphaFold Database (AFDB) structures, an extensive MD simulation dataset, and an experimental protein folding stability dataset. This method allows the model to generalize to new protein sequences and predict various conformations. It has successfully identified the structures of LapD, a regulatory protein in Vibrio cholerae bacteria, including both known and unobserved intermediate conformations.

BioEmu-1 demonstrates strong performance in modeling protein conformational changes and stability predictions. The model achieves 85% coverage for domain motion and 72–74% coverage for local unfolding events, indicating its ability to capture structural flexibility. The BioEmu-Benchmarks repository provides benchmark code, allowing researchers to evaluate and reproduce the model’s performance on various protein structure prediction tasks.

Experts in the field have noted the significance of this advancement. For example, Lakshmi Prasad Y. commented:

The open-sourcing of BioEmu-1 by Microsoft Research marks a significant leap in overcoming the scalability and computational challenges of traditional molecular dynamics (MD) simulations. By integrating AlphaFold, MD trajectories, and experimental stability metrics, BioEmu-1 enhances the accuracy and efficiency of protein conformational predictions. The diffusion-based generative approach allows for high-speed exploration of free-energy landscapes, uncovering crucial intermediate states and transient binding pockets.

Moreover, Nathan Baker, a senior director of partnerships for Chemistry and Materials at Microsoft, reflected on the broader implications:

I ran my first MD simulation over 25 years ago, and my younger self could not have imagined having a powerful method like this to explore protein conformational space. It makes me want to go back and revisit some of those molecules!

BioEmu-1 is now open-source and available through Azure AI Foundry Labs, providing researchers with a more efficient method for studying protein dynamics. By predicting protein stability and structural variations, it can contribute to advancements in drug discovery, protein engineering, and related fields.

More information about the model and results can be found in the official paper.
