JBoss Middleware

Application Modernization and Migration Tech Talk + Scotland JBug Meetup

Application Modernization and Migration Tech Talk + Scotland JBug Meetup

I’m heading back to my friends in Scotland to speak at the JBoss User Group (JBug) Scotland next month. It’s a fun group of people who really seem to enjoy working with open source and JBoss software stacks.

First off, on June 6th there will be a wonderful tech talk on application modernization and migration. This is followed by the JBug Scotland hosting a  hands-on workshop. Come and get hands-on experience in a workshop showcasing application development in the cloud using containers, JBoss middleware, services, business logic, and APIs.

The events are on June 6th, 2018 from 14:00 onwards and are scheduled as follows.

Bringing Coolstore Microservices to the Service Mesh: Part 2–Manual Injection

Bringing Coolstore Microservices to the Service Mesh: Part 2–Manual Injection

Coolstore+Istio Logo

In the first part of this series we explored the Istio project and how Red Hat is committed to and actively involved in the project and working to integrate it into Kubernetes and OpenShift to bring the benefits of a service mesh to our customers and the wider communities involved. If you want to play with Istio, check out the service mesh tutorials on learn.openshift.com. If you want to install it, follow the Istio Kubernetes quickstart instructions and install it on OpenShift 3.7 or later. Also don’t miss Don Schenck’s series of blogs on Istio technology in general to learn more about it and what Red Hat is doing in this space.

In this post, we will deploy the existing Coolstore microservices demo as a service mesh and start to demonstrate the tangible value you can get out of the system without any major rewrite or rearchitecture of the existing app. We’ll also improve our project along the way to adhere to Istio (and general microservice) best practices. In the real world, your applications and developers often make bad assumptions or fail to implement best practices, so with this information you can learn something about your own projects. For Coolstore, many of these workarounds will eventually find their way into the source code of the demo.

How to Build an Intelligent IoT Gateway in 7 Easy Steps

In previous blogs, I talked about the the critical role of the IoT gateway in the enterprise Internet of Things (IoT) as it enables real time decision-making at the edge, secures downstream devices and optimizes network utilization. So how does one go about building this gateway? In this blog, you’ll learn how to build an intelligent IoT gateway in a few simple steps – you can find the code at  GitHub.

To automate the gateway provisioning, we’ll using Ansible by Red Hat. Why? Because it is the simplest and best tool out there for this job. Besides, it can also be used for configuration management and application deployment. Once you’re ready to provision and deploy thousands of gateways in a production environment, you can use this same Ansible tool. This is how IT departments provision the systems securely across the network.
