Setting up RBAC on Red Hat AMQ Broker

One thing that is common in the enterprise world, especially in highly regulated industries, is to have separation of duties. Role-based access controls (RBAC) have built-in support for separation of duties. Roles determine what operations a user can and cannot perform. This post provides an example of how to configure proper RBAC on top of Red Hat AMQ, a flexible, high-performance messaging platform based on the open source Apache ActiveMQ Artemis project.

In most of the cases, separation of duties on Red Hat AMQ can be divided into three primary roles:

  1. Administrator role, which will have all permissions
  2. Application role, which will have permission to publish, consume, or produce messages to a specific address, subscribe to topics or queues, or create and delete addresses.
  3. Operation role, which will have read-only permission via the web console or supported protocols

To implement those roles, Red Hat AMQ has several security features that need be configured, as described in the following sections.

How to migrate your SOAP web service to REST with Camel

SOAP-based services are plentiful in many enterprise solutions and are slowly being replaced by RESTful services to simplify their use. There is a new wizard to help you make the transition with Apache Camel’s Rest DSL added in the latest version of Red Hat Fuse Tooling. This article shows how to use the new wizard to transition from older SOAP-based services to more modern REST-based services.

If you aren’t familiar, Red Hat Fuse is an integration platform based on Camel and a number of other projects. The updating Fuse Tooling is available in Red Hat Developer Studio 12.0.0, the desktop IDE that is based on Eclipse 4.8 Photon. You can also get the new wizard by adding JBoss Tools 4.6 to your existing Eclipse 4.8 Photon installation by downloading it directly, or installing via the Eclipse Marketplace.

Monitoring Red Hat AMQ 7 with the jmxtrans Agent

Monitoring Red Hat AMQ 7

Red Hat AMQ 7 includes some tools for monitoring the Red Hat AMQ broker. These tools allow you to get metrics about the performance and behavior of the broker and its resources. Metrics are very important for measuring performance and for identifying issues that are causing poor performance.

The following components are included for monitoring the Red Hat AMQ 7 broker:

  • Management web console that is based on Hawtio: This console includes some perspectives and dashboards for monitoring the most important components of the broker.
  • A Jolokia REST-like API: This provides full access to JMX beans through HTTP requests.
  • Red Hat JBoss Operation Network: This is an enterprise, Java-based administration and management platform for developing, testing, deploying, and monitoring Red Hat JBoss Middleware applications.

These tools are incredible and fully integrated with the original product. However, there are cases where Red Hat AMQ 7 is deployed in environments where other tools are used to monitor the broker, for example, jmxtrans.

Red Hat Fuse 7 Is Now Available

Red Hat Fuse 7 (formerly called Red Hat JBoss Fuse) is now officially available. This cloud-native, distributed solution allows developers to easily develop, deploy and scale integration applications. Architects can compose and orchestrate microservices with Red Hat Fuse to introduce agility to the systems. In this release, Fuse also empowers integration experts and business users to become more productive with the self-service low-code platform. With this new agile integration solution, enterprises can now engage in wider collaboration with and among partners at a much quicker pace.

Here’s where you can download it: https://developers.redhat.com/products/fuse/download/.

Adding API Gateway Policies Now Easier With Red Hat 3scale API Management

With the June 2018 release of Red Hat 3scale API Management 2.2, adding API Gateway policies to your API management layer is easier than ever.

What is a Policy?

Red Hat 3scale API Management provides units of functionality that modify the behavior of the API Gateway without the need to implement code. These management components are know in 3scale as policies. The configuration for the bundled policies is available from the API Manager Portal, where you can define the behavior of your API integration.

The order in which the policies are executed, known as the “policy chain”, can be configured to introduce differing behavior based on the position of the policy in the chain. Adding custom headers, perform URL rewriting, enable CORS, and configurable caching are some of the most common API gateway capabilities implemented as policies.

Red Hat Summit: An Eventful Tour from Enterprise Integration to Serverless

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. Standing in front of a packed room at Red Hat Summit, their talk addressed four basic points:

  1. Event-driven architectures have been around for a while. What are they, why are they powerful, and why are back en vogue?
  2. Messaging is often used as a backbone for event-based distributed systems. What options do we have for cloud-native event-driven architectures?
  3. Integration is necessary for any organization. How do streaming, cloud-native architectures, and microservices fit in?
  4. Are Functions-as-a-Service (FaaS) the next utopian architecture? Where do functions fit in a world of microservices?

The entire session was done with three enterprise concerns in mind. First is the divide between agile systems and purpose-built systems. While the purpose-built system is optimized for a small set of use cases, it is very difficult to change if new use cases arise or the old use cases become irrelevant. We have to be agile to adapt to a constantly changing environment. Another concern is resource utilization. We want to eliminate waste and get the most out of our systems and resources, although the cloud in general and containers in particular make more distributed architectures practical. Finally, Christian made the observation that we cannot build complex systems from complex parts. The components we develop must be as simple and understandable as possible.

Scaling AMQ 7 Brokers with AMQ Interconnect

Red Hat JBoss AMQ Interconnect provides flexible routing of messages between AMQP-enabled endpoints, including clients, brokers, and standalone services. With a single connection to a network of AMQ Interconnect routers, a client can exchange messages with any other endpoint connected to the network.

AMQ Interconnect can create various topologies to manage a high volume of traffic or define an elastic network in front of AMQ 7 brokers. This article shows a sample AMQ Interconnect topology for scaling AMQ 7 brokers easily.

Next DevNation Live: Camel Riders in the Cloud, March 15th, 12pm EDT

The next online DevNation Live Tech Talk will be Thursday, March 15th at 12pm EDT. The topic is Camel Riders in the Cloud presented by Claus Ibsen

Apache Camel has fundamentally changed the way enterprise Java™ developers think about system-to-system integration. It makes it easy to apply enterprise integration patterns (EIP) using simple declarations. The result is a lightweight application that is wrapped and delivered as a single JAR.

In this session, we’ll show you how to apply the best practices from the enterprise integration world to build microservices that are deployed as Linux® containers, running on top of Kubernetes and Red Hat OpenShift. These integration applications will be both cloud-native and cloud-portable.

Register now and join the live presentation at 12pm EDT, Thursday, March 15th. 

Note: For those outside of the US, daylight savings time started this week, so the US East coast is now UTC – 4.
