AMQ Replication HA Policy

Demonstrating Red Hat JBoss AMQ 7 HA Replication Failover

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.

How to build a containerized IoT solution with OpenShift

For businesses looking to build scalable Internet of Things (IoT) solutions using containers, here is a sample project built on the Red Hat OpenShift Container Platform. This project implements an intelligent IoT gateway on the OpenShift Container platform. The IoT Gateway is critical for enterprise IoT as it brings intelligence, and enables key services, at the edge. In this project, the gateway application is deployed as a set of microservices inside containers on OpenShift.

You had me at Hello, World

Our Red Hat Developers program team has just concluded a “Time to Hello World” project to reduce the time it takes you to download and install a new technology, and then get to your first “hello world” application.  By utilizing multiple resources from Red Hat engineering, UX, evangelists, docs, testing, and yes, even customers, this is just one of many Red Hat activities underway to minimize speed bumps when trying a new Red Hat technology.

So, is 6 minutes quick enough to try out a new technology?  If so, read on.

Behind the Internet of Things Middleware Demo at Red Hat Summit

InternetofThings-01This year at Red Hat Summit, I was part of a team whose objective was to create a running, IoT-focused system, at some scale (hundreds of beacons, millions of events), based on a real-world use case to demo live, on stage during the middleware keynote at Red Hat Summit.

Our team chose the area of asset tracking, where important machines, tools or equipment (think mobile ultra-sound machines in hospitals) need to be located on demand and tracked for their usage each day, week, month, year. But, for our demo, instead of machines, we asked Red Hat Summit attendees to participate as our “assets” by wearing Bluetooth Low Energy (BLE) beacons to track their movement throughout the conference.

DevNation 2014 – Scott Cranton and Scott McCarty – Resilient Enterprise Messaging with JBoss A-MQ

Abstract from DevNation 2014:  Messaging has become a critical infrastructure component for both developers and systems administrators. Scaling infrastructure in an efficient and manageable way is critical in modern physical, virtual and cloud infrastructures. To provide value to the business, developers and systems administrators must understand technical and business advantages of current and future architectures.

Join Scott McCarty and Scott Cranton as they bring years of experience in building scalable, fault tolerant, distributed systems to the architectural challenges of building durable messaging platforms. Attendees will receive guidance on emerging technologies as well as an understanding of the strengths of current solutions like Red Hat JBoss A-MQ.
