Domain-specific Prometheus metrics with Red Hat Process Automation Manager and Decision Manager

By Duncan Doyle October 31, 2019July 1, 2020

Since version 7.4, Red Hat Process Automation Manager (RHPAM) and Red Hat Decision Manager (RHDM) provide support for monitoring various metrics through Prometheus. The platform’s Execution Server (also known as KIE-Server) provides a Prometheus extension which, if enabled, exposes metrics like the number of containers deployed, the response time of rule and decision evaluations, etc.

In this example, we will use the RHDM 7 Insurance Pricing Demo as our base project. This demo contains a simple Decision Model and Notation (DMN) model that calculates the insurance price based on the age of the customer and whether the customer had previous incidents. The GitHub repository for this demo can be found here and contains detailed instructions on how to set up and run the demo.

Kogito for Quarkus intelligent applications

By Karina Varela August 29, 2019August 28, 2019

The Quarkus project is becoming quite popular among developers. Quarkus provides a fast-dev environment, and it has already a set of libraries, standards, and frameworks that are made available through extensions like RestEasy, Panache, SmallRye, Keycloak, and Kafka. Additionally, you can start using Kogito today to create intelligent Quarkus applications.

Enabling CI/CD for Red Hat Decision Manager on OpenShift

By Cheng Kuan Gan July 22, 2019August 28, 2020

As part of the microservices adoption journey, there will come a time when an organization starts to implement more and more rules services as part of the total application solution landscape. There could be hundreds of rules services to be managed and deployed at one time, making the job of the application team more challenging and eventually causing delays to the entire production rollout.

Red Hat Decision Manager (RHDM) is a solution that enables developers and application teams to implement decision services or business rules for their application needs. I will be covering how we can fully utilize the capabilities brought by Red Hat Decision Manager and Red Hat OpenShift to enable a smooth CI/CD process, in order to have rapid decision services deployment. (This tutorial assumes you already have a good understanding of RHDM and OpenShift.)

Modern business logic tooling workshop, lab 3: Create a domain model

By Eric D. Schabell April 19, 2019April 17, 2019

Since starting to update my free online rules and process automation workshops that showcase how to get started using modern business logic tooling, we’ve come a long way with process automation. The updates started with moving from JBoss BPM to Red Hat Decision Manager and from JBoss BPM Suite to Red Hat Process Automation Manager.

The first lab update showed how to install Red Hat Decision Manager on your laptop, and the second lab showed how to create a new project. This article highlights the newest lab update for Red Hat Process Automation Manager, where you’ll learn how to create a domain model.

Let’s take a look at the lab, shall we?

Good news: Business automation is not about SOA

By Karina Varela February 20, 2019February 19, 2019

This is not an article about service-oriented architecture (SOA); neither is it a business process management (BPM) article. This article is about how business automation can change the way you create software.

At a first, developers and architects tend to associate the use of BPM suites (or business-oriented architecture) with SOA. This behavior immediately leads to an incorrect bias about the subject.

C-suite executives understand: Transform—or be suppressed by new, disruptive, technology-driven startups. In 2019, business automation is a key transformation that executives will seek in order to improve business performance and lower costs. However, some technology teams are not very open to it. Why?

In the past, BPM suites have been used as big centralized orchestrators for services, external systems, and human tasks. JBoss SOA Platform, released in 2008, is an example of such an integration platform. Unfortunately, this kind of application does not fit new cloud- and microservices-oriented architectures. The good news is that business automation evolved and can help teams to reach the next step in DevOps: BizDevOps.

Modern business logic tooling workshop, lab 1: Installation

By Eric D. Schabell December 19, 2018

Recently I’ve started updating my free online workshops for business rules and process automation that showcase how to get started using modern business logic tooling. These updates start with moving from Red Hat JBoss BRMS to Red Hat Decision Manager and from Red Hat JBoss BPM Suite to Red Hat Process Automation Manager.

This article highlights the first lab update for Red Hat Decision Manager, where you learn to install Decision Manager on your laptop.

Demystifying the Red Hat Decision Manager and Process Automation Manager Remote Client

By Duncan Doyle December 10, 2018

KIE-Server is the light-weight, cloud-native, rules and process execution runtime of the Red Hat Decision Manager (RHDM) and Red Hat Process Automation Manager (RHPAM) platforms. Lately, I’ve gotten more and more questions on how to use the KIE-Server Client Java API to interact with the KIE-Server execution runtime of RHDM (formerly called Red Hat JBoss BRMS) and RHPAM (RHPAM). To answers these questions, and to create a future reference, I decided to write a number of code examples, accompanied by this article.

The KIE-Server Client Java API provides an easy way for Java applications to communicate with the KIE-Server execution engine of RHDM and RHPAM. The API abstracts the application from the underlying REST and/or JMS communication protocol and transport, making integrations with the server easier to build, test, and maintain.

Quickly try Red Hat Decision Manager in your Cloud

By Eric D. Schabell November 19, 2018November 18, 2018

It’s been some time since I last talked with you about business logic engines and using them in application development cloud architectures. At that time, I showcased running JBoss BRMS in a container on Red Hat OpenShift. This gives you the cloud experience, one that’s portable across private and public clouds, but on your own local laptop using Red Hat Container Development Kit.

The world continues to move forward, a new product has been released which replaced JBoss BRMS with the Red Hat Decision Manager, so now I want to provide a way for you to install this on OpenShift, in the same easy to use demo format.
