This Week in Spring, October 23rd, 2018 - Oracle CodeOne Edition

Hi Spring fans! Welcome to another installment of This Week in Spring! This week I’ve just flown back from Canada and Russia where I was at the amazing Joker conference in St. Petersburg. I’m now in San Francisco (where I live!) for a couple of days to soak up the amazing atmosphere around Oracle CodeOne, reunited with the Java community and longtime friends. I’m so excited about the presentation that fellow Java Champion Trisha Gee and I are doing tomorrow at 11:30 am that introduces an end-to-end reactive and Spring-based application from JavaFX client to service. Do not miss this!

Functional Bean Registrations in Spring Cloud Function

Spring Cloud Function has a couple of new features in 2.0 (still in milestone phase), and possibly the most dramatic is the ability to go "fully functional". This is made possible by changes in Spring Boot 2.1 together with Spring Framework 5.1, and it means a different way of thinking about bean definitions in Spring applications, but also significant improvements in startup performance.

AWS Cost Savings

It’s always good to start with a picture, especially if it tells a story. Here’s a graph that shows the improvement in Spring Cloud Function 2.0 over 1.0, comparing the cost of cold starts in AWS:

Memory Cost

The x-axis is memory in MB, and the y-axis is cost of a cold start in GBsec. The most dramatic effect is for low memory containers, where the cost is almost 4 times lower. The origin of the improvement is in dramatically shorter startup times, which in turn come from using the functional form of bean definitions in the application. Josh made a video about functional bean registration a while ago if you need an introduction (it’s on YouTube). Now let’s have a closer look at how it works in Spring Cloud Function.

This Week in Spring - Tuesday, October 2nd, 2018

Whew! What a week! I’m exhausted! I’ve been running around visting one customer after another this week and it’s only Tuesday! My brain is still a smoldering hole from the craziness of last week’s epic SpringOne Platform 2018 event in Washington DC, and needless to say there’s a ton of new things to investigate and tons of videos to be available to the audience soon. This week is a wee bit more tame, so without further ado, let’s get to it!

I don’t know where you are in the world as you read this but I hope you’ll join me 17:00 BST, for my appearance at the vJUG where I’ll be looking at Bootiful Testing - join us!

The evolution of Spring Fu

I take the opportunity of a short stop between SpringOne platform where I gave the first talk about Spring Fu and Kotlinconf to give an overview of the evolution of this project, summarize the current status and share what could be the next steps.

Early June, I announced a new experimental project named Spring Fu, with the goal to experiment on a new kind of API to configure Spring applications using Kotlin DSL and functional configuration.
