Interview with JAX London speaker Andrew Morgan

This is why we need modern service virtualisation

As we work more with distributed systems, microservices and legacy services, we introduce a web of inter-service dependencies that cause us to face many challenges across our development and deployment pipeline. Resource consumption, deployment time, our testing feedback cycle, third party service flakiness and costing can cause problems. We talked to Andrew Morgan, Consultant at OpenCredo and speaker at the upcoming JAX London about how the technique of ‘API Simulation’ (modern service virtualisation) can be used to overcome these issues.

Why running 1000+ actor systems on one JVM is a bad idea

Akka anti-patterns: too many actor systems

Admittedly I’ve seen this one in use only one time, but it was one time too many. For some reason I keep seeing clients come up with this during design discussions and reviews, therefore it makes it into the list of Akka anti-patterns.

Insights gained during JavaOne 2016

A glimpse at Java EE’s future

Last week was the annual JavaOne conference in San Francisco. I had the opportunity to attend the conference and even had a chance to speak in a session — my session was titled “Java EE, Beyond the Basics.” This article summarizes what was presented at JavaOne regarding what’s coming in Java EE 8 and 9. Every single speaker made it a point to state that Java EE’s 8 and 9 plans are in early stages and this is all subject to change.

A match made in heaven?

OpenShift 3 + Eclipse Che

The concept of universal workspaces, championed by Eclipse Che, gave Red Hat the ability to easily replicate and distribute the entire development workspace. Red Hat and Codenvy have integrated Che with OpenShift, providing an easy way to copy both your runtime, and your development workspace.
