We’re pleased to announce a second milestone release of Spring Statemachine 1.0.0.M2.

With this milestone we focused on features in regions and pseudostates. Regions provide more sophisticated functionality for a parallel execution of a states machines and pseudostates will bring more functionality for working with initial, terminate, history, choice, fork and join states.

One might ask what is a region and how it works with a state machine. A state machine is a specialization of a region where orthogonal regions are composed of a multiple independent state machines. This is a difficult…

We’re pleased to announce the first version of the Apache Ambari plugin for Spring XD.

Ambari is a cluster provisioning tool to install and manage various Apache projects like HDFS, YARN, Zookeeper or Kafka. Ambari has a concept of a stack definition which is used by both Pivotal and Hortonworks. The stack definition is usually made up of components supported by the maintainer.

This Ambari integration adds support for provisioning Spring XD with Pivotal HD 3.0 and Hortonworks HDP 2.2.

Spring XD is not part of the main Ambari distribution for PHD or HDP. However, it is easy to extend an…

Welcome to another installment of This Week in Spring! This week I'm in New York City in advance of QCon NYC next week talking to customers and working with the local Pivotal Labs team. If you're around be sure to say hi and let's talk code.

So, as usual, we've got a lot to cover so let's get to it.

As Josh mentioned in "This Week in Spring" already, Eugen Paraschiv recently did a noteworthy survey on the adoption of Spring 4 and Java 8 as well as Spring Boot: http://www.baeldung.com/java-8-spring-4-and-spring-boot-adoption

Those are interesting numbers for us. Within the Spring universe, Java 8 adoption seems to be approaching 40%! And in terms of Spring Framework versions, Spring 4 is at 65% already, which I'm really happy to see. Even taking into account that a large part of the corporate use of Spring might not be represented in those numbers, that's a great trend. And Pivotal's…

CI on the Cloud with Jenkins, Spring and Cloud Foundry

Speaker: Jamie O’Meara, Pivotal

This presentation will highlight an integrated development process that involves Spring code built with CloudBees Jenkins Enterprise and deployed to CloudFoundry. A software lifecycle of continuous delivery from source code control (Git) to Jenkins build (Maven and Gradle) to live deployment on a Cloud Foundry instance will be shown. We will demo using Jenkins to do a blue/green application deployment. With a Cloud Foundry blue/green Jenkins deployment, you can push a new version of the application and have a software router add that to an existing version of the application's route. The two versions are then load-balanced, allowing for testing of the new version and easy replacement or fall-back to the existing version. Developers can run builds on private and public clouds with deploy to either/both Jenkins running on a PaaS and integrated into the PaaS. We will run a hands-on demo and show the beauty and simplicity of an integrated build pipeline with Spring, Jenkins and Cloud Foundry.
