If you are just getting started in the world of Docker and are beyond the point of running simple standalone containers that live and die on one host with no container orchestrator managing them for you, then Docker Swarm is a good next step into the world of container orchestration. Its simple to setup, stable, … Continue reading Simple architecture for Docker Swarm and Traefik footprints
Lets migrate everything to containers. Everything. The app infrastructure, the apps themselves, deployment workflows, DevOps procedures... everything. Recently started winding down one of those "on and off again" projects with long term goals but was constantly susceptible to the day to day distractions and diversions typical for any team managing a ton of different apps. … Continue reading Migrate everything to containers, you will
After going through a lot of R&D of deploying Hazelcast enabled apps as Docker Containers, first starting on pre-Docker 1.12 (legacy swarm, w/ mgrs/agents etc), with Registrator and Consul, ended up creating the hazelcast-consul-discovery-spi (available on GitHub). This served its purpose well, but as Docker evolved and post 1.12 "swarm mode" came out with the … Continue reading Hazelcast discovery with Docker Swarm
Everyone once in a while during the life cycle of any given piece of software comes that time where you have the opportunity to improve it in a major way....if that is, its lucky enough to still be in production. One particular system I've been involved with is responsible for processing a lot of data … Continue reading Reactive re-engineering with Akka
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 … Continue reading Hazelcast discovery with Etcd

Ever wondered how Liferay's internal clustering works? I had to dig into it in context of my other article on globally load balancing Liferay across separate data-centers. This blog post merely serves as a place for my research notes and might be helpful for someone else who is trying to follow what is going on … Continue reading Liferay clustering internals
