Welcome to another installment of This Week in Spring! This week I'm in Las Vegas at the mega EMC World event.

• Spring Security lead Rob Winch has just announced that Spring Security SAML 1.0.1 is now available
• Phillip Verheyden's talk offers a very pragmatic look athow to move Spring 3 application - including dependencies like Jackson and Hibernate - to take advantage of newer and new features in Spring 4.x.
• My pal Adib Saikali's SpringOne2GX 2014 talk on building a rich client backends with Spring is now up
• Don't miss this replay of Spring ninja Greg Turnquist's talk on debugging and maintaining Spring Boot applications
• Dustin Whittle's talk on how to performance testing (Spring) applications is filled with useful tools, tips-and-tricks for…

Welcome to another installment of This Week in Spring! This week, I'm in Barcelona, Spain for the Spring I/O conference.

• Spring Social lead Craig Walls just announced the release of Spring Social Facebook 2.0.1, the first maintenance release in the Spring Social Facebook 2.0 line.
• the good Dr. Syer just published a blog on different ways to bind services in Cloud Foundry
• Spring Security lead Rob Winch just released Spring Security 4.0.1, the first maintenance release in the Spring Security 4.0 line
• This Week's SpringOne2GX Replays are out! Marius Bogoevici shows us how to Build highly modular and testable business systems with Spring Integration, Brian Cavalier talks about Efficient Client-Server Communication with Differential Synchronization and JSON Patch and Topher Bullock and Will Tran review Server-side JavaScript with Nashorn and Spring…

In this article we look at how to bind a Spring Boot application to data services (JDBC, NoSQL, messaging etc.) and the various sources of default and automatic behaviour in Cloud Foundry, providing some guidance about which ones to use and which ones will be active under what conditions. Spring Boot provides a lot of autoconfiguration and external binding features, some of which are relevant to Cloud Foundry, and many of which are not. Spring Cloud Connectors is a library that you can use in your application if you want to create your own components programmatically, but it doesn't do…

Welcome to another installment of This Week in Spring! This week I'm in Bangalore, India, at the Great Indian Developer Summit. Lots of the Spring Team are at JAXConf in Germany this week as well.

A friendly reminder, if you're in the south west region of Europe, and Barcelona, Spain, specifically, and looking for fun in the sun, I can think of no better option than Spring I/O Conference, which is next week. Don't miss the many great talks from many amazing Spring team and Spring community members. I'll be there and looking forward to meeting and seeing you all!

Without further ado, let's get…

Application configuration is an evolution. It starts as a hard-coded strings in your application and hopefully progresses to something external, such as a file or system property that can be changed without deployment. But what happens when other enterprise concerns enter the mix, such as audit requirements or access control around who can make changes? How do you maintain the consistency of values across too many application servers to manage at one time from a terminal window? The next step in the application configuration evolution is centralized configuration that can be accessed by your applications as they move through your various environments on their way to production. Such a service transfers the ownership of configuration from the last developer who touched the code to a well-versed application owner who is responsible for the configuration of the application across all environments. At Dealer.com, we have created one such solution that relies on Apache ZooKeeper to handle the storage and coordination of the configuration data and Spring to handle to the retrieval, creation and registration of configured objects in each application. The end result is a transparent framework that provides the same configured objects that could have been created using a Spring configuration, configuration file and property value wiring. This talk will cover both the why and how of our solution, with a focus on how we leveraged the powerful attributes of both Apache ZooKeeper and Spring to rid our application of local configuration files and provide a consistent mechanism for application configuration in our enterprise.

Applications generated more and more data than ever before and a huge part of the challenge - before it can even be analyzed - is accommodating the load in the first place. Apache's Kafka meets this challenge. It was originally designed by LinkedIn and subsequently open-sourced in 2011. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds. The design is heavily influenced by transaction logs. It is a messaging system, similar to traditional messaging systems like RabbitMQ, ActiveMQ, MQSeries, but it's ideal for log aggregation…

Welcome to another installment of This Week in Spring! As usual, we've got a lot to discuss so let's get to it!

Last week I was in Paris, France, for Devoxx, FR, and this week I'm in India for the Great Indian Developer Summit and for some meetings ahead of the conference in Bangalore and Hyderabad. If you're in Bombay, Hyderabad, or Bangalore, and want to talk Spring, Cloud Foundry, and big-data, let me know!

In a week and some change, I'll be in Barcelona, Spain, for Spring I/O. If you're in Spain, be sure not to miss this amazing event! I, along with many other members of the Spring team…

Welcome to another installment of This Week in Spring! This week, I'm off to Paris, France for Devoxx France. Many of us on the Spring and Cloud Foundry teams will be there, so don't hesitate to reach out if you're about, we'd love to hear from you! Also, even if you're not at the show, come meet many of us on the Spring team (including Juergen Hoeller himself, Stéphane Nicoll, Brian Clozel, Sébastien Deleuze and of course yours truly) at this free Devoxx France event.

Also, this Thursday I'll be speaking at the vJUG again, this time on building microservices with Spring Cloud. Don't miss it!

We believe that the development of cloud-native application architectures is the next great evolutionary phase of enterprise application development. These architectures combine elements like twelve-factor applications, microservices, self-service agile infrastructure, API-based collaboration, and antifragility. All of these elements enable us to simultaneously move quickly and safely as we continuously deliver business value to our customers.

The Spring team's goal has always been to win the war on Java complexity, and now we're teaming up with our colleagues on the Cloud Foundry team to…
