In this article, I will discuss how to capture incoming and outgoing messages for Red Hat AMQ 7 (RHAMQ 7). This might advantageous if you need to log the incoming or outgoing traffic, or the messages from a broker, or during development and/or testing when you want to see all message. Additionally, There may also be a need to modify messages in transit. Using RHAMQ 7 interceptors, you can intercept traffic to and from the RHAMQ 7 broker. You can also modify messages using the interceptor.

This post is a continuation of the series on Red Hat AMQ 7 security topics for developers and ops people started by Mary Cochran. We will see how to configure LDAP authentication on a Red Hat AMQ 7 broker instance. In order to do so, we will go perform the followings actions:
- Set up a simple LDAP server with a set of users and groups using Apache Directory Studio.
- Connect Red Hat AMQ 7 to LDAP using authentication providers.
- Enable custom LDAP authorization policies in Red Hat AMQ 7.

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:
- Administrator role, which will have all permissions
- 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.
- 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.

There is a major push in the United Kingdom to replace aging mechanical electricity meters with connected smart meters. New meters allow consumers to more closely monitor their energy usage and associated cost, and they enable the suppliers to automate the billing process because the meters automatically report fine-grained energy use.
This post describes an architecture for processing a stream of meter readings using Strimzi, which offers support for running Apache Kafka in a container environment (Red Hat OpenShift). The data has been made available through a UK research project that collected data from energy producers, distributors, and consumers from 2011 to 2014. The TC1a dataset used here contains data from 8,000 domestic customers on half-hour intervals in the following form:

In this article, we will use a Python-based messaging client to connect and subscribe to a topic with a durable subscription in the Apache ActiveMQ Artemis broker. We will use the text-based STOMP protocol to connect and subscribe to the broker. STOMP clients can communicate with any STOMP message broker to provide messaging interoperability among many languages, platforms, and brokers.
If you need to brush up on the difference between persistence and durability in messaging, check Mary Cochran’s article on developers.redhat.com/blog.
A similar process can be used with Red Hat AMQ 7. The broker in Red Hat AMQ 7 is based on the Apache ActiveMQ Artemis project. See the overview on developers.redhat.com for more information.

We are excited to announce a Developer Preview of Red Hat AMQ Streams, a new addition to Red Hat AMQ, focused on running Apache Kafka on OpenShift.
Apache Kafka is a leading real-time, distributed messaging platform for building data pipelines and streaming applications.
Using Kafka, applications can:
- Publish and subscribe to streams of records.
- Store streams of records.
- Process records as they occur.

Red Hat JBoss AMQ 7 provides fast, lightweight, and secure messaging for internet-scale applications. In addition, AMQ 7 components use industry-standard message protocols and support a wide range of programming languages and operating environments.
Therefore, AMQ 7 gives you the strong foundation you need to build modern distributed applications. Especially relevant is that multiple instances of AMQ 7 brokers can be grouped together to share message processing load.
Each broker manages its own messages and connections and is connected to other brokers with “cluster bridges” that are used to send topology information, such as queues and consumers, as well as load balancing messages.
AMQ 7 supports two different strategies for backing up a server: shared store and replication.

It was more than 2 years ago that I blogged about building a Managed File Transfer (MFT) solution using Fuse and AMQ. First, many things have progressed, particularly the technology landscape. Second, MFT protocols have evolved. AS4 provides a new and improved way of securely exchanging documents over HTTP. In addition, the OASIS consortium governs a vendor-neutral open standard. This is great news, but how do we achieve support for these new standards and transports with our antiquated, legacy, and proprietary MFT software?

A few weeks ago, the newest version of Red Hat JBoss AMQ was released. AMQ 7 is the result of Red Hat’s efforts on creating a unified messaging platform for its middleware offerings. One of the most interesting features of this new version is the new backing strategy for failovering when configured in high availability. This feature allows clients connections to migrate from one server to another in the event of server failure so client applications can continue to operate.
AMQ 6.x already had an option to configure failover using a shared store, usually backed up by a shared filesystem or a JDBC connection to a database. However, that option involved the use of external infrastructure add-on in hardware and software, representing an increase in overall deployment costs.
In AMQ 7, support for network-based replication was added. When using replication, the live and the backup servers do not share the same data directories; all data synchronization is done over the network. Therefore, all (persistent) data received by the live server will be duplicated to the backup.
