In the first blog in the DRA series, we introduced the concept of Dynamic Resource Allocation (DRA) that recently went GA in Kubernetes v1.34 which was released end of August 2025.
In the second blog, we installed a Kuberneres v1.34 cluster and deployed an example DRA driver on it with "simulated GPUs". In this blog, we’ll will deploy a few workloads on the DRA enabled Kubernetes cluster to understand how "Resource Claim" and "ResourceClaimTemplates" work.

Cloud providers offering GPU or Neo Cloud services need accurate and automated mechanisms to track resource consumption. Usage data becomes the foundation for billing, showback, or chargeback models that customers expect. The Rafay Platform provides usage metering APIs that can be easily integrated into a provider’s billing system. '
In this blog, we’ll walk through how to use these APIs with a sample Python script to generate detailed usage reports.
Our upcoming release update will add support for a number of new features and enhancements. This blog is focused on the upcoming support for Upstream Kubernetes on nodes based on Red Hat Enterprise Linux (RHEL) v10.0. Both new cluster provisioning and in-place upgrades of Kubernetes clusters will be supported for lifecycle management.
At Rafay, we are continuously evolving our platform to deliver powerful capabilities that streamline and accelerate the software delivery lifecycle. One such enhancement is the recent update to our GitOps pipeline engine, designed to optimize execution time and flexibility — enabling a better experience for platform teams and developers alike.
Rafay provides a tightly integrated pipeline framework that supports a range of common operational use cases, including:
System Synchronization: Use Git as the single source of truth to orchestrate controller configurations
Application Deployment: Define and automate your app deployment process directly from version-controlled pipelines
Approval Workflows: Insert optional approval gates to control when and how specific pipeline stages are triggered, offering an added layer of governance and compliance
This comprehensive design empowers platform teams to standardize delivery patterns while still accommodating organization-specific controls and policies.
Historically, Rafay’s GitOps pipeline executed all stages sequentially, regardless of interdependencies. While effective for simpler workflows, this model imposed time constraints for more complex operations.
With our latest update, the pipeline engine now supports Directed Acyclic Graphs (DAGs) — allowing stages to execute in parallel, wherever dependencies allow.
Recently, Bitnami announced significant changes to its container image distribution here. As part of this update, the Bitnami public catalog (docker.io/bitnami) will be permanently deleted on September 29th.
All existing container images (including older or versioned tags such as 2.50.0, 10.6, etc.) will be moved from the public catalog (docker.io/bitnami) to a Bitnami Legacy repository (docker.io/bitnamilegacy).
The legacy catalog will no longer receive updates or support. It is intended only as a temporary migration solution to give users time to transition.
Implementing Day-2 Operations such as agent replacement is cumbersome today because every configuration tied to a previous agent must be reconfigured manually. This makes tasks like scaling, retiring agents, or handling failures both error-prone and time-consuming.
To address this pain point, we are introducing the concept of an Agent Pool.
Instead of binding configurations directly to individual agents, customers can now attach multiple agents to a shared Agent Pool. Configurations such as Environment Templates and Resource Templates reference the pool, rather than a single agent.
This simple shift brings significant operational benefits:
Seamless Failover and Replacement
Add or remove agents from a pool without reconfiguring existing associations.
Simplified Day-2 Operations
Manage scaling, upgrades, and retirements without disruption.
Load Balancing
Distribute load across multiple agents within a pool for higher availability and performance.
In the previous blog, we introduced the concept of Dynamic Resource Allocation (DRA) that just went GA in Kubernetes v1.34 which was released in August 2025.
In this blog post, we’ll will configure DRA on a Kubernetes 1.34 cluster.

Artificial intelligence (AI) and high-performance computing (HPC) workloads are evolving at unprecedented speed. Enterprises today require infrastructure that can scale elastically, provide consistent performance, and ensure secure multi-tenant operation. NVIDIA’s Performance Reference Architecture (PRA), built on HGX platforms with Shared NVSwitch GPU Passthrough Virtualization, delivers precisely this capability.
This is the introductory blog in a multi part series. In this blog, we explain why PRA is critical for modern enterprises and service providers, highlight the benefits of adoption, and outline the key steps required to successfully deploy and support the PRA design/architecture.
When it came to selecting an immutable operating system for Rafay's Kubernetes Distribution (Rafay MKS), we found ourselves evaluating two strong contenders: Talos and Flatcar Linux. Both offered immutability and a focus on running containers, but in the end, Flatcar Linux won out for our needs. In this blog, we provide a deeper look into why we made that choice, and how the pros and cons stacked up.
Whether you're training deep learning models, running simulations, or just curious about your GPU's performance, nvidia-smi is your go-to command-line tool. Short for NVIDIA System Management Interface, this utility provides essential real-time information about your NVIDIA GPU’s health, workload, and performance.
In this blog, we’ll explore what nvidia-smi is, how to use it, and walk through a real output from a system using an NVIDIA T1000 8GB GPU.
