Streams for Apache Kafka

[In case you aren't following the OpenShift blog, I'm cross posting my article here because I think it will be of interest to the Red Hat Developer commnity.] The Open Service Broker API standard aims to standardize how services (cloud, third-party, on-premise, legacy, etc) are delivered to applications running on cloud platforms like OpenShift. This allows applications to consume services the exact same way no matter on which cloud platform they are deployed. The service broker pluggable architecture enables admins...

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 other endpoints, enabling you to scale your AMQ 7 brokers easily.

The project Deployment automation AMQ 7 High Availability Shared Store provides deployment automation of an AMQ 7 high availability configuration with a shared store, and it provides you with a cluster of two nodes (master/slave) deployed on different hosts or on the same host.

Have you ever thought about having your own cloud environment? A local cloud is one of the best things you can do to better understand all the gears that run inside a highly productive environment. How do I know that? I've done it! And I'm ready to show you how I did, and how you can do it.

When using Byteman scripts for tracing and debugging with Red Hat JBoss Fuse and AMQ, learn how to use Java helper classes with for advanced options, such as viewing or modifying arguments, and utilizing 'java.util.logging' to inject messages into the existing logs.

In a production or customer environment it is not always possible to identify issues by looking at logs or setting up a remote debugging using IDE. Often the issues are specific to the environment and can't be reproduced. having byteman scripts can help in identifying issues without actual code changes.

This article would help to configure http2 protocol support for the camel-undertow component. Camel's undertow component use embedded undertow web-container of version undertow-core:jar:1.4.21. This version also supports the http2 connection. I have used camel version 2.21.0-SNAPSHOT from upstream https://github.com/apache/camel. Also, the curl version to test application using camel-undertow component is 7.53.1. This curl version supports --http2 flag for sending an http2 request. I have also used nghttp to test application from linux terminal. However, this article is not about http2...

AMQ7 is full of new and exciting technology and capabilities. However, with both routers and brokers now securing your topology can get confusing. Particularly securing the routers and learning how to use clients with them, using AMQP can be challenging for those of us used to using jks files and pure jms. SSL between Routers The first step in securing traffic between routers is getting your pem files for your key and certificate. These steps will also give you a...

Ansible example of updating gluster container native storage.

In this post, I wanted to address how to configure mKahaDB persistence storage on ActiveMQ for better management and reducing disk usage. Default configured KahaDB persistence adapter works well when all the destinations (queues/topics) being managed by the broker have similar performance. However, an enterprise solution where several third parties are involved is never the case. There are multiple queues or topics and different consumers or listeners listening to these queues/topics. Some consumers might be slower than other consumers. This...

Arm TechCon 2017 - Embedded, IoT, Networking and no Server focus Last month was Arm TechCon, the annual developer conference showcasing offerings from Arm and its partners. Arm laid out its vision and strategy to achieving even greater integration in its processors and circumventing the slowing Moore’s law. As always, there was a bevy of new product announcements but overall, the show seemed to lack the energy of the last few years and especially the excitement of last year after...

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...

We know that containers in Openshift or Kubernetes don't persist data. Every time we start an application, it is started in a new container with an immutable Docker image. Hence, any persisted data in the file systems is lost when the container stops. Hence if an application or container is rebuilt or restarted than we can't view previous logs or if we are using containers with mysql or any other database then schema, tables, and all data will be lost...

At the beginning of October, I attended JavaOne in San Francisco to present on WildFly Swarm and Apache Kafka. For those of you that weren't able to attend the session, or for those that did and saw first hand the issues with the demo, I will be covering all the details of how the demo should work! The presentation material that was presented at JavaOne can be found here, and all the code for the demos is in GitHub. MiniShift...

We hear about Microservices a lot nowadays. Its implementation requires us to deal with new challenges. A key question that comes with using microservices is how to handle interactions in an asynchronous way. The answer to that is messaging. Among other things, messaging features the following: Loose coupling since it decouples client from services. Improved availability since the message broker buffers messages until the consumer is able to process them. Supports a variety of communication patterns including request/reply, notifications, request/async...

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...

First of all: It's a Release Candidate and the features I'll show you are marked as Tech Preview, so use them for testing purpose ONLY! We cannot use Minishift just because there is no Minishift updated yet. Anyway, I'll show how could use its base iso-image. I don't want to use 'oc...

Ansible is a simple agent-less automation tool that has changed the world for the better. It has many use cases and wide adoption (used by many upstream projects like Kubernetes and there are thousands of rules submitted to Ansible Galaxy). In this article, we are going to demonstrate Ansible. The intention of this article is not to teach you the basics of Ansible, but to motivate you to learn it. Why is Bash scripting not automation? Shell has been the...
