Rapid Cloud Development with Spring Roo – Part 2: VMware Cloud Foundry

Spring Roo is a tool to offer rapid application development on the Java platform. It supports two solutions for Cloud Computing at the moment: Google App Engine (GAE) and VMware Cloud Foundry. Both provide the Platform as a Service (PaaS) concept. This article will discuss the Cloud Foundry support of Spring Roo. GAE was discussed in part 1 of this article series (https://www.kai-waehner.de/blog/2011/07/18/rapid-cloud-development-with-spring-roo-%E2%80%93-part-1-google-app-engine-gae).

Java / JVM – When to use Multicast (e.g. Tibco Rendevous) instead of Point-to-Point Messaging (JMS Implementations)

Several solutions are available in the Java / JVM environment for messaging. All have in common that they exist for many years and still do its job in mission critical systems: Sending remote messages fast and reliable. There exist two different concepts which compete against each other for enterprise messaging solutions. This article describes and compares Point-to-Point (e.g. ActiveMQ) and Multicast (e.g. Tibco Rendevous) messaging to answer the question when to use which one. Although both solutions are available for many years now, this question is still very important – also for new software!
