Spring Batch on Kubernetes: Efficient batch processing at scale

Engineering | Mahmoud Ben Hassine | January 27, 2021 | ...

Introduction

Batch processing has been a challenging area of computer science since its inception in the early days of punch cards and magnetic tapes. Nowadays, the modern cloud computing era comes with a whole new set of challenges for how to develop and operate batch workload efficiently in a cloud environment. In this blog post, I introduce some of the challenges a batch developer or architect may face when designing and running batch applications at scale and show how Spring Batch, Spring Boot and Kubernetes can tremendously simplify this task.

YMNNALFT: The Spring *Utils Classes

Engineering | Josh Long | January 27, 2021 | ...

Welcome to another installment of You May Not Need Another Library For That (YMNNALFT)! I've spent a lot of time since 2016 illuminating (or trying to, anyway!) some of the more enormous opportunities in the Spring ecosystem in my Spring Tips videos. Today, however, I come to you in a different spirit, wanting to focus on the little, sometimes hidden, gems that do fantastic things and that might spare you an additional third-party dependency and its implied complexity.

Then, there's some factory method for building a java.util.Collection<T>, so you extract it out into a separate class and expose it as a static method. And eventually, you've got a whole collection of these things scoured about your codebase, and there's little to no cohesion across them. After all, there's just not that much to it, right? These are, essentially, only global functions, not really methods on stateful objects,

Hi, Spring fans! Welcome to another installment of This Week in Spring! As I type this I'm sitting on the amazing Tanzu Tuesday's stream as a (guest) cohost with Tiffany Jernigan (@tiffanyfayj) learning about tips and tricks for working with Spring Boot and Kubernetes from the Spring team's Oliver Hughes (@olliehughes82). If you missed it, then it - and all sorts of other content - is available for replays on our Tanzu Twitch.tv channel.

Now then, we've got a ton of good stuff to get to so let's gooo...

This post was written by our friend on the Azure Spring Cloud team, the amazing Kylie Liang (@liangkylie). I interviewed her for the Bootiful Podcast in April 2019, too! -Josh

2020 was a busy year for Azure Spring Cloud service. Microsoft and VMware co-announced Azure Spring Cloud General Availability (GA).
