Securing Open Liberty applications with Azure Active Directory via OpenID Connect 

Long gone are the days when you had to create your own user account management, authentication, and authorization for your web delivered software. Instead, contemporary applications leverage these functions (Identity and Access Management or IAM for short) from an external provider. As a full-featured Java application runtime, Open Liberty has great options for externally provided IAM....Read more

Extreme programming meets systematic testing using Coyote 

Our world is increasingly reliant on cloud services that are expected to have high availability and handle high throughput with minimal latency. These services are also expected to be resilient and reliable in the presence of internal and external failures, while maintaining a high quality bar in the presence of continuous evolution and change. This...Read more

Announcing cloud-native workflows using Dapr and Logic Apps 

The Distributed Application Runtime (Dapr) project is growing rapidly are we’re grateful for all the community support and customer feedback. While working with customers building business applications, we find that one of the most frequent needs is the ability to schedule, automate, and orchestrate business processes. This is often called a business workflow. Workflows also...Read more

Scaling Kubernetes: Intro to Kubernetes-based event-driven autoscaling (KEDA) 

A Kubernetes cluster requires compute resources to run applications and these resources may need to increase or decrease depending on the application requirements. This typically falls under the category of “scaling” and can be broadly divided into cluster and application scaling. To deal with increasing requirements, such as high traffic, you can scale out your...Read more

More “Python for Beginners” videos…times two! 

When Susan and I created the Python for Beginners series last fall, we had the goal of trying to help new developers make the transition into one of the most popular and flexible programming languages available. We focused on some of the most common features and attempted to bring you to the point where you...Read more

In-cluster CNAB management with Brigade 

Next week is KubeCon North America 2019, but we wanted to give you an early preview of one of the things we’ll be showing. Over the last few years, we’ve been working on tools for the cloud native ecosystem. From Helm and Brigade to Porter and Rudr, each tool we have built is designed to stand on its own. But our vision...Read more

Tutorial: Calico Network Policies with Azure Kubernetes Service 

In May 2019, Network Policies on Azure Kubernetes Service (AKS) became generally available through the Azure native policy plug-in or through the community project Calico. This user-defined network policy feature enables secure network segmentation within Kubernetes and allows cluster operators to control which pods can communicate with each other and resources outside the cluster. In this...Read more

A new video series for beginners to learn Python programming 

Probably the largest hurdle when learning any new programming language is simply knowing where to get started. What’s important? What do I need to know to be proficient? It’s hard to follow docs when you’re not even sure what you’re reading. You might be taking a look at Python. Maybe you’re drawn because of its...Read more

Trill 103: Ingress, Egress, and Trill’s notion of time 

Congratulations! You’ve made it to the next installment of our overview of Trill, Microsoft’s open source streaming data engine. As noted in our previous posts about basic queries and joins, Trill is a temporal query processor. Trill works with data that has some intrinsic notion of time. However, Trill doesn’t assign any semantics to that...Read more

DevSecOps in Kubernetes 

Traditional security processes can often become a roadblock when delivering software via DevOps processes at the rate that today’s business world demands. Today, security is not just the responsibility of the security teams—it is a shared responsibility among all the teams in the applications lifecycle. This integration is known as DevSecOps. DevSecOps is not about...Read more
