Developing microservices on Kubernetes

Microservices and microservice architecture is the modern approach to building cloud applications as independent services using Kubernetes.

One of the greatest challenges of moving from traditional monolithic application design to a microservices architecture is being able to monitor your business transaction flow—the flow of events via micro service calls throughout your entire system.

What are Microservices?

Microservices are an architecture for breaking up a monolithic application into a collection of smaller pieces. Each of those pieces provides a particular function via a well-defined and carefully managed API. The collection delivers the same overall business value as the original monolithic application, but the independence of the individual pieces means they can be updated much more quickly without impacting the overall collection. (This requires, of course, that any changes to the API are done in a backwards-compatible way.)

Choosing the right asynchronous-messaging infrastructure for the job

Choosing the right asynchronous-messaging infrastructure for the job

July 31, 2020

The term asynchronous means “not occurring at the same time.” In the context of distributed systems and messaging, this term implies that request processing will occur at an arbitrary point in time. Asynchronous interactions hold many advantages over synchronous ones, but they also introduce new challenges. In this article, we will focus on specific considerations […]

Creating event sources in the OpenShift 4.5 web console

Creating event sources in the OpenShift 4.5 web console

July 28, 2020

Red Hat OpenShift 4.5 makes it easier than ever to deploy and run event-driven applications that react to real-time information via event notifications. Empowered by OpenShift Serverless, applications come to life through events, scaling up resources as needed (or up to a pre-configured limit), and then scaling back to zero after the resource burst is […]

Flexible single sign-on authentication and more in Open Liberty 20.0.0.7

Flexible single sign-on authentication and more in Open Liberty 20.0.0.7

July 17, 2020

Open Liberty 20.0.0.7 lets you disable the default of returning Lightweight Third-Party Authentication (LTPA) cookies for authentication when using Trust Association Interceptor (TAI) or Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) authentication. You can also disable JSON Web Token (JWT)  cookies when using JWT’s single sign-on (SSO) feature. In this article, we introduce these improvements […]

Migrating Spring Boot tests to Quarkus

Migrating Spring Boot tests to Quarkus

July 17, 2020

As developers, we don’t always consider test migration when we think about adopting a new framework. Tests are important, however, because they ensure that our code meets its requirements and works as desired, especially when we add new features and functionality. Test migration is an essential part of migrating to a new application development framework. […]

Developing at the edge: Best practices for edge computing

July 16, 2020

Edge computing continues to gain force as ever more companies increase their investments in edge, even if they’re only dipping their toes in with small-scale pilot deployments. Emerging use cases like Internet-of-Things (IoT), augmented reality, and virtual reality (AR/VR), robotics, and telecommunications-network functions are often cited as key drivers for companies moving computing to the […]

Developing and testing on production with Kubernetes and Istio Workspace

July 14, 2020

Due to container-orchestration platforms like Kubernetes and Red Hat OpenShift, developers have become very efficient about deploying and managing distributed and containerized applications. But can we say the same about application development and testing? In this article, I briefly discuss how cloud-native development is transforming the traditional development cycle of coding, building, and testing. I […]
