Welcome to the final installment in this three-part series about using Ansible Collection for JCliff to manage WildFly or Red Hat JBoss Enterprise Application Platform (JBoss EAP) instances. Previously, we’ve discussed installing and configuring the JCliff Ansible collection and using its basic features. In this article, we discuss advanced options available with the project’s latest release. Without further ado, let’s dive in!

There are many ways to configure the cache in a microservices system. As a rule of thumb, you should use caching only in one place; for example, you should not use the cache in both the HTTP and application layers. Distributed caching both increases cloud-native application performance and minimizes the overhead of creating new microservices.

A Kubernetes Operator acts as an automated site reliability engineer for its application, encoding the skills of an expert administrator in software. For example, an Operator can manage a cluster of database servers and configure and manage its application. It can also install a database cluster of a declared software version and a designated number of members.

If you are a developer considering modernizing your Java applications by containerizing or migrating them to a more modern application server, then you are likely aware of Red Hat’s migration toolkit for applications. This article helps you get started with migration toolkit for applications by installing it directly on your laptop. For more about the toolkit, see:
- The recent migration toolkit for applications 5.1.0 feature update.
- Our guide to analyzing monolithic Java applications in multiple workspaces.
Note: Red Hat’s migration toolkit for applications (formerly Red Hat Application Migration Toolkit) is based on the upstream, open source Windup project. Check out the code and see how it works!

In this article, you will learn how to use Debezium with Apache Avro and Apicurio Registry to efficiently monitor change events in a MySQL database. We will set up and run a demonstration using Apache Avro rather than the default JSON converter for Debezium serialization. We will use Apache Avro with the Apicurio service registry to externalize Debezium’s event data schema and reduce the payload of captured events.

Analyze monolithic Java applications in multiple workspaces with Red Hat’s migration toolkit for applications
Transforming monolithic Java applications into distributed, cloud-native microservices is never easy, but Red Hat’s migration toolkit for applications helps you understand and evaluate the migration path. As a developer, you can apply the following features to a broad range of transformation use cases:

This article introduces new storage installation options and features in the Red Hat Integration service registry. The service registry component is based on Apicurio. You can use it to store and retrieve service artifacts such as OpenAPI specifications and AsyncAPI definitions, and for schemas such as Apache Avro, JSON, and Google Protobuf. We’ve provided Red Hat Integration’s Service Registry 1.1 component as a general availability (GA) release in Red Hat Integration 2020-Q4.
