As I'm sure most readers are aware, Java SE 8 was released last month. In conjunction with the recent release of STS 3.5.0 and its complete support for JDK 8, we thought now would be an ideal time to upgrade Sagan to take advantage of the new language features and APIs. Note: Not yet familiar with the Sagan project? It's the Spring reference application that powers this blog and everything else at spring.io. Check out the first three posts in this series for more details. Cloud Foundry's Java buildpack has provided support for JDK 8 since the day it was released. To begin using it, we've…
Last week, I began this series by announcing that the Sagan reference app is now open source and showed how to get up and running with it on your own machine. In this post, I want to walk through how we push Sagan into production at spring.io multiple times a day with zero downtime using blue-green deployments. You may have heard of this technique before; Martin Fowler gave it a write-up a few years ago, and there is a section on it in the highly-recommended book Continuous Delivery. In a nutshell, it goes like this: maintain two copies of your production environment ("blue" and "green…
When we launched the new spring.io, we left comments off the blog. On one hand this was because we were time-constrained, and leaving them off was the simplest thing to do. On the other hand, it was an experiment in minimalism. We thought we'd see if we could reduce the number of channels for feedback, and in doing so improve the quality all around. We asked everyone to route their questions and feedback on our blog posts to the @springcentral Twitter handle, and many of you did that—thanks! So how did it go? Well, we heard some feedback from the community that they miss comments on the blog…
Chances are good that if you're reading this post you're well aware that springsource.org has been redesigned and relaunched as spring.io. We're happy to report that since the launch at SpringOne last month, reception for the new site has been positive and constructive. Thanks to all that have been providing feedback via @springcentral – please keep it coming! If you are looking around for the first time, the all-new collection of guides is a good place to start. Keep in mind that each guide is backed by a GitHub repository, meaning you can clone everything locally and provide feedback via…
