Welcome to our penultimate JBoss Weekly Editorial for 2017 and my final ride through the JBoss Communities in search of all which is interesting and useful, I hope to have found something of interest to keep you busy as the year comes to a close.
Microservices with Vert.x
Vert.x is a small footprint, asynchronous framework which is ideally suited for Microservices applications; as examples of its capabilities and small footprint we have two excellent articles demonstrating its applicability on small footprint devices and the cloud. In our first article Usman demonstrates how to run a small Vert.x application on a Raspberry Pi, part of his hobby project to control the behaviour of the Raspberry Pi using Google Home Mini and/or Alexa. In our second article Lazar demonstrates how to integrate Vert.x with AWS Lambda, enabling small footprint, reactive, cloud based serverless applications to be developed and deployed at scale in the cloud.
Blockchain in the Cloud
Blockchain technology has been in the news for various reasons, not only as the basis for various cryptocurrencies but also as a decentralised application platform supporting smart contracts on top of the distributed ledger. At a recent Red Hat Customer Forum event in Sydney, Australia a small team gave a live demonstration showing how a fictitious company called Destinasia Travel could leverage the power of the distributed ledger to implement a shared Loyalty Points system with many of their customers travel services.
Sagas and Narayana LRA
The Narayana transaction manager provides an implementation of the saga transactional pattern through Narayana LRA (Long Running Actions) however this is not the only framework available, in the first article this week from the transaction team Martin introduces three frameworks, Narayana LRA, Axon framework and Eventuate.io and compares their features and usability. If you wish to learn more about sagas and how they differ from two-phase commit transactions then Ondra's article will walk you through the details, discussing compensation actions and their coordination as implemented in Narayana LRA.
Choosing between Apache Camel DSLs
When working with Apache Camel you have a choice to work with the XML or Java DSLs so how to you choose which is the better option? The answer obviously depends a lot on your circumstances as well as how each option will fit in with your processes and team and in order to determine which to use you will first need advice on how they compare to each other.
