microservices

This article, which is Part 3 of the series, covers details pertaining to the specific elements (mobile and web application deployments) that can be used in a generic architectural blueprint for the omnichannel customer experience use case.

Learn about deploying tools to debug microservices on Kubernetes/OpenShift, including OpenTracing,  Squash, Telepresence, and a Squash Operator in Ansible Automation.

Spring Boot developers, learn Eclipse MicroProfile by comparing the implementation of a microservice in Spring Boot and MicroProfile.

This post described the new Spring Boot Starters provided in Red Hat Process Automation Manager 7.1. Using a minimal amount of code, these Spring Boot Starters enable developers of modern, light-weight applications on Spring Boot to quickly build applications or microservices that have business process and business rules execution capabilities.

This post is the first in a series that describes a lightweight cloud-native distributed microservices framework called EventFlow that targets the Kubernetes/OpenShift platforms and models event-processing applications as a connected flow or stream of components. EventFlow can be used to develop event-processing applications that can process CloudEvents, which are an effort to standardise upon a data format for exchanging information regarding events generated by cloud platforms.

Red Hat Developer Studio 12.9 and the community edition, JBoss Tools 4.9.0 for Eclipse Photon 2018-09, are now available. This article highlights some of the new features in both JBoss Tools and Eclipse Photon, covering WildFly, Spring Boot, Camel, Maven, and many Java-related improvements—including full Java 10 support.

Given Kubernetes, docker containers and service mesh, are we seeing the start of an imminent decline in the use of application servers? This article explores the use case for application servers and examines why they will continue to evolve.

Managing distributed transactions across multiple microservices is challenging. Two solutions, two-phase commits and the Saga pattern are explored and compared.

The Kiali project provides observability of a service mesh and the services in the mesh. This post describes how to use Kiali to observe what the microservices in your Istio service mesh are doing, validate the Istio configuration, and see any issues.

There are pros and cons using to a microservices architecture. Some teams decide not to strictly follow all the principles of the "pure" microservices architecture. This post explores some valid reasons for using or not using microservices, and it discusses alternatives.

This post is the first in a series that examines new trends in modern application development and whether Kubernetes is "the new application server."

This article shows how to use Apache QPid Proton (or Red Hat AMQ Interconnect) as a message router, the Vert.x AMQP bridge, and the Advanced Message Queuing Protocol (AMQP) for asynchronous request-reply communication between two microservices. Since AMQP is a wire-level protocol, services written in other stacks (like .NET) can also use the same communication channel.

Sabre recently announced it has chosen Red Hat OpenShift Container Platform to fuel its digital transformation as it exits from transaction processing on the mainframe with TPF. OpenShift will be the basis of its next-generation platform, which will include microservices, DevOps, and a multi-faceted cloud strategy, to revolutionize the travel business.

Read about the latest features in Red Hat Developer Studio 12.0, JBoss Tools 4.6.0, and Eclipse 4.8 Photon including Java 10 support. Developer Studio is a bundled installer. JBoss Tools can be added to your existing Eclipse 4.8 installation.

Learn how to process and aggregate huge streams of IoT data using Strimzi and Apache Kafka on Red Hat OpenShift. The data stream is processed using the Red Hat AMQ distributed streaming platform to perform aggregations in real time as data is ingested into the application.

This article demonstrates how to implement a contract-first API design using Apicurio and Red Hat Fuse. It shows how to create an OpenAPI standard document as a contract between API providers and consumers using Apicurio and how to quickly create mock tests using Red Hat Fuse.

The next online DevNation Live is June 21st at 12pm EDT for "Advanced Microservices Tracing with Jaeger", presented by Red Hat software engineers Pavol Loffay and Juraci Paixão Kröhling.

Building container-based solutions can be a challenging task that adds a lot of overhead for application developers, but using a combination of Red Hat OpenShift Application Runtimes and Istio will take care of many considerations, leaving application developers to focus on implementing the business logic.

Eclipse Che 6.6 is here, and since the release of Che 6.0, the community has added a number of new capabilities. In this article, learn about new features and how to get started using Che with Kubernetes, Red Hat OpenShift, and Docker.

The next online DevNation Live is June 7th at 12pm EDT for "Your Journey to a Serverless World—An Introduction to Serverless", presented by Kamesh Sampath and hosted by Burr Sutter.

If you need to build some Python-based microservices, one way to do it is to install Python in a Red Hat Enterprise Linux virtual machine and use Flask, a microframework that makes building RESTful services easy.

See how the Kafka-CDI library can handle difficult setup tasks and make creating Kafka-powered event-driven applications for MicroProfile and Jakarta EE very easy.

Modernizing a monolithic application by introducing microservices has some significant risks. Red Hat's Christian Posta shares his experiences helping customers move to microservices, providing lots of practical advice and insight along the way.

Red Hat Senior Architects Marius Bogoevici and Christian Posta recently presented an overview of event-driven architecture, taking the audience from the basics of enterprise integration to microservices and serverless computing.
