Hazelcast discovery with Etcd

I’ve used Hazelcast for years and have generally relied upon the availability of multicast for Hazelcast cluster discovery and formation (within a single data-center). Recently was faced with two things, expand the footprint into a non-multicast enabled data-center and secondly pre-prep the service for containerization where nodes will come and go as scaling policies dictate […]

By the title of this book one might expect some coverage of some of the microservices frameworks out there, concrete examples, maybe […]

Clustering Liferay globally across data centers (GSLB) with JGroups and RELAY2

Recently I’ve have been looking into options to solve the problem of GSLB’ing (global server load balancing) a Liferay Portal instance. This article is a work in progress… and a long one. Jan Eerdekens states it correctly in his article, “Configuring a Liferay cluster is part experience and part black magic” …. however doing it […]

Part 2: Nevado JMS, Ehcache JMS WAN replication and AWS

This post is a followup to what is now part one, of my research into using Ehcache, JMS, Nevado, AWS, SNS and SQS to permit cache events to be replicated across different data-centers. @see https://github.com/bitsofinfo/ehcache-jms-wan-replicator In my first post I was able to successfully get Ehcache’s JMS Replication to function using Nevado JMS as the provider after patching the […]
