Hi, Spring fans! Welcome to another incredible installment of all that’s fit to tweet, blog, record, and print about Spring! It’s been an insane week! Since our last installment I was in Paris, FR, for the epic Devoxx FR conference where I spoke at a meetup hosted by ZenikaIT, gave a workshop on Reactive Cloud Native Java and co-presented a talk on Reactive Spring with the one-and-only Juergen Hoeller. I jumped off stage and ran to the airport to board a flight leaving 150 minutes later headed back to the US!
Now, you may have heard that Pivotal, the company that leads and/or at least actively invests in a good many open-source projects - including Spring, Cloud Foundry, Apache Tomcat, Reactor, JUnit, Kubernetes, Redis, Micrometer and so many others besides - listed on the New York Stock Exchange on the 20th of April, 2018: we’re a public company now!
So: I know I speak for the Spring team and Pivotal at large when I say that Pivotal’s success is your success and that this wouldn’t, couldn’t, have been possible without you, dear community; THANK YOU!
It is a dream come true to work on open-source software that helps people build amazing things with such an amazing, curious, compassionate and passionate community. It’s a big part of the reason I am happier every day than I was the day before; there’s always something amazing happening!
Now, I wish all of you could’ve been there! Don’t feel left out though; you can watch the ringing of the bell on the floor of the NYSE here.
We published an official thing about the IPO, as well. You might like that, too.
The IPO was last Friday, but by the weekend I was on a plane headed back to Europe. This week I’m in Mainz, Germany for the JAX conference where I’ll be presenting, again, on “Reactive Spring” with Spring Framework lead and co-founder Juergen Hoeller, and on testing with Spring. Then, it’s off to the DevOne conference in Linz, Austria where Juergen and I will _again_present! (How lucky am I??) I’ll also be doing a longer workshop-like talk on the 27th of April in Vienna, Austria. Then, finally, it’s off to Melbourne, Australia, for Voxxed Melbourne where, next week, I’ll be co-presenting with Spring framework founder and Atomist CEO Rod Johnson. Do not miss this!
All that wonderful business, we have a lot to cover, so let’s get to it!
- If you use a separate repository to store Spring Cloud Contract definitions, by adding a small test, you can sketch the graph of dependencies between your projects! See this issue for more
- This post looks at how to autoscale Cloud Foundry applications by investigating RabbitMQ queue depth. This is awesome; it’s one less thing that needs to be in the book Cloud Native Java where we demonstrated how to do this exact thing using a Spring Cloud Data Flow RabbitMQ metrics source and a Cloud Foundry autoscaler sink.
