Updating Microservices with Netty 5, Kafka 3, and React: Whirlpool Revisited

John Boardman Development Technologies, Java, JavaScript, Microservices, React Leave a Comment

Back in 2015 and 2016, I wrote two blogs that went step by step to develop a microservice/Netty architecture with fully working code called Whirlpool.

A lot has changed in the years since, so recently I decided to come back to the project, update it with the latest versions of Kafka and Netty, and add a React UI to it (rather than the vanilla JavaScript version it used before). In addition, I also added Windows Subsystem for Linux (WSL) scripts in addition to the Mac and Linux scripts that were there before and made all of the scripts more robust.

This blog will be about the work that went into all of those updates, plus a look at the new React UI. This provides an excellent view into what it takes to update an outdated microservices application implemented with Kafka (version .9 –>3.0) and Netty (4.1.3->5.0.0-alpha2), bringing all versions up to date and adding a React UI. By the end you’ll be familiar with the latest versions of these frameworks, know some “gotchas” to avoid, as well as understand how to integrate WebSockets into React.

Leveraging Docker to Quickly Setup an Object Detection API

Adam Costenbader Cloud, Development Technologies, Docker, Tutorial 1 Comment

In this blog, we utilize the strengths of Docker containers to quickly spin up two separate containers that we can utilize for our software development needs – one running the DeepStack API software and the other running a utility to help us get started with the DeepStack API.

The best part is that once we are comfortable with our setup, we could quickly and easily stop and remove the DeepStackUI utility container to free up resources all while continuing to run the DeepStack API software without interruption.

Microservices in the Wild: Three Types & How to Implement

Dallas Monson Architecture, Cloud, Development Technologies, Microservices Leave a Comment

Microservices has become a catch-all term in the industry used to describe anything from architecture patterns to actual service implementations.

With such a broad spectrum, it can be daunting to know what it is, what it isn’t, and maybe more importantly, why we should care.

In this post, I’ll provide an overview of three kinds of Microservices that I have observed in client architectures: Domain, Integration, and Unit-of-Work. I’ll also discuss specific examples of their purposes and a method to implement each one.

GitOps provides a declarative approach for improving the management of application delivery.

In this 50-minute video, Keyhole Principal Consultant Jaime Niswonger discusses basic GitOps fundamentals and various implementations in a Kubernetes environment. He covers GitOps best practices that unify deployment, management, and monitoring for containerized clusters and applications. Then he introduces ArgoCD and shows its capabilities in an OpenShift/Kubernetes environment. Jaime includes his own experiences and what he has seen working with companies across various industries.
