Fixed `rad workspace show` errors when no current workspace exists

The rad workspace show command has been updated to improve usability. Previously, if no workspace was set, the command would return an error, which could be confusing. With this release, the command now logs an informational message to guide you when no current workspace exists. This change ensures a more user-friendly experience when managing workspaces. For more details, refer to the CLI documentation.

Deploy a RAG chatbot app using Radius

Mon, 24 Nov 2025 08:00:00 -0800

Agentic AI applications are rapidly becoming a cornerstone of modern software, enabling systems to reason, act, and interact with data in unprecedented ways. As these intelligent applications grow in complexity, managing their infrastructure and governance becomes increasingly challenging. For instance, a Retrieval-Augmented Generation (RAG) chatbot application might require a combination of vector databases, large language models (LLMs), and traditional compute, on top of which considerations like dependency management, security, and compliance are layered. Indeed, when looking at some of the most popular AI sample applications, we see that they often involve multiple components and services that need to be orchestrated outside the bounds of the core application itself before the application can even run.

In-place upgrades now available

Tue, 16 Sep 2025 00:00:00 +0000

Up until now, upgrading a Radius installation meant manually redeploying the control plane. This was cumbersome and risked downtime for your internal platform. Beginning with Radius v0.50, we’re excited to announce support for in-place upgrades of the Radius control plane. Using the new rad upgrade command, platform engineers can now upgrade a running Radius control plane to a new version without rebuilding their Environments or disrupting running applications. This enhancement makes it much easier to keep up with new Radius releases in production, thanks to built-in safety checks and a rollback capability.

Contribute Your First Resource Type and Recipe

Mon, 11 Aug 2025 00:00:00 +0000

Radius helps platform engineers build powerful Internal Developer Platforms (IDPs) with curated resource catalogs that empower developers to build applications that adhere to all enterprise best practices. Key to delivering custom resource catalogs is the Radius Resource Types feature.

Think of Radius Resource Types as the developer’s interface to your platform. They define a contract—a set of properties developers use to provision infrastructure without needing to know the implementation details. Platform engineers then create Recipes—the implementation of that contract—using tools like Terraform or Bicep to deploy and manage the actual cloud resources, ensuring that best practices related to security, compliance, and cost are followed by default.

Future Proofing AI Applications via Radius Resource Types

Fri, 18 Jul 2025 00:00:00 +0000

Building Applications in the AI Era

Imagine you’re an enterprise developer building your first AI-powered application. You start with Anthropic’s Claude, ramp on the APIs, write your application code, configure authentication, test the application and successfully deploy it to production. Everything is working great but, three months later, your organization migrates to an entirely different AI model, such as Google Gemini, for better results or for cost optimization. Suddenly, you’re facing days or weeks of refactoring and testing across environments before redeploying the same application using the different model.

Introducing Radius Resource Types

Tue, 17 Jun 2025 00:00:00 +0000

The Radius maintainers and community have been hard at work enabling platform engineers to build internal developer platforms that are application-centric with a great developer experience. This week Radius launched Radius Resource Types, reinforcing its core mission to decouple application definitions from underlying infrastructure.

Enterprises integrating Radius into their internal developer platform tell us they need to customize the API for common resource types such as a PostgreSQL database to simplify the developer experience (allowing developers to select T-shirt sizes, for example). Others want to create abstract resource types such as a web service that may have a reverse proxy, an application container, and an in-memory cache all encapsulated in one single type. Radius Resource Types enable platform engineers to accomplish these exact scenarios. Platform engineers now have complete flexibility in defining the resources developers use in their applications and, separately, the implementation of those resources using Terraform configurations or Bicep templates (referred to generally as Recipes in Radius).

Deploy your Radius applications to Azure Container Instances

Tue, 03 Jun 2025 08:00:00 -0800

An important part of the Radius vision is to be platform agnostic, and that includes the underlying compute such that Radius can deploy the same application across different compute platforms. Thus, it’s always been a goal to support additional container runtimes beyond just Kubernetes. That’s why we’re excited to share that Radius now supports deploying your applications to additional container platforms, beginning with Azure Container Instances. This integration provides Radius users with a serverless container compute option that enables platform engineers to build developer platforms that are decoupled from specific container runtimes while still benefiting from the Radius application-centric approach and separation of concerns.

Platform Engineering : Integrating Radius into your GitOps Flux workflow

Tue, 20 May 2025 08:00:00 -0800

GitOps is an approach to managing infrastructure and applications using Git as the single source of truth and has become quite popular in the DevOps and Platform Engineering disciplines. This approach provides several benefits - including declarative management of infrastructure definitions and auditable change logs. Radius fits nicely into this workflow, allowing you to define your applications and infrastructure with Radius and then use GitOps to deploy and manage them across your deployment platforms.

Platform Engineering with Radius to build application-centric IDPs

Tue, 13 May 2025 00:00:00 -0800

Very early in my career I worked on a long-forgotten system called the HP-3000. I wrote batch processing applications in Pascal to process financial transactions. Then I transitioned to being a web application developer. Moving from the world where each batch application had a single executable and maybe a few shared libraries to the world of web applications was a big change. I remember trying to wrap my head around how it all worked. There were so many different applications all communicating with other applications. Of course, I quickly learned that it was a simple model-view-controller pattern, and the application was just a collection of binaries and HTML templates.

Platform engineering with Radius at KubeCon London 2025

Thu, 24 Apr 2025 08:00:00 -0800

I had a great time at KubeCon London earlier this month presenting and demoing Radius and meeting members of the Radius community! Thanks to everyone for taking time to stop by and chat. It was very fun to meet so many community members in person versus over video conference. 😊

Anyone familiar with Radius will know that platform engineers have become the primary focus for the maintainers. That’s because so many Radius early adopters are platform engineering teams who are integrating Radius into their internal developer platforms (IDPs). A great example is Nuno Guedes and his platform engineering team at Millennium bcp (the largest private bank in Portugal). The Millennium bcp team has integrated Radius into their IDP and have been using it in production since December 2024. Nuno is the head of cloud at Millennium bcp and he and I co-presented on his use of Radius at KubeCon London. To learn more about how the Millennium bcp team is using Radius in their IDP, please check out our joint presentation How Millennium bcp Leverages Radius to Empower Developer + Operator Collaboration (CNCF YouTube channel | Slides from presentation).
