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.)

Running an event-driven health management business process through a few scenarios: Part 1

March 31, 2020

In the previous series of articles, Designing an event-driven business process at scale: A health management example (which you need to read to fully understand this one), you designed and implemented an event-driven scalable business process for the population health management use case. Now, you will run this process through a few scenarios. In this […]

DevNation Tech Talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions plus code and sample projects to help you get started. In this talk, you’ll learn about distributing your microservices data with events, Command Query Responsibility Segregation (CQRS), and event sourcing from Edson Yanaga, Red Hat’s Director […]

Low-code microservices orchestration with Syndesis

Low-code microservices orchestration with Syndesis

March 25, 2020

Recently I wrote about decoupling infrastructure code from microservices. I found that Apache Camel and Debezium provided the middleware I needed for that project, with minimal coding on my end. After my successful experiment, I wondered if it would be possible to orchestrate two or more similarly decoupled microservices into a new service–and could I […]

C# 8 default interface methods

C# 8 default interface methods

March 3, 2020

In the previous articles, we discussed C# 8 async streams and pattern matching. In this article, we’ll look at C# 8 default interface methods. Extending interfaces Before C# 8, it was not possible to add members to an interface without breaking the classes that implement the interface. Because interface members were abstract, classes needed to […]

How to ignore files in Git without .gitignore

February 25, 2020

Git has a handy feature when it comes to preventing accidental file check-ins when the files are meant to stay local. The obvious candidates are compiled binaries when you only want to check in the source code. Other candidates are files with local configurations. One can put all of those files and paths into a […]

Designing an event-driven process at scale: Part 3

February 21, 2020

In the first article in this series, Designing an event-driven business process at scale: A health management example, Part 1, you found the business use case and data model for a concrete example from the health management industry. You then began implementing the example in jBPM (an open source business automation suite) by creating the Trigger […]
