OpenValue live: Scaling online groceries with Java at Picnic from Spring Boot to Quarkus

Weve worked hard on presenting you the next best thing after in-person meetups: a high quality live stream with lots of room for interaction with the speakers! You can tune in to the stream from the comfort of your home and ask questions via the live chat.
A host will monitor the chat for questions and relay them to the speakers. Guest speaker and Java champion Sander Mak Picnic will kick off sharing how an online grocery store evolved their systems while growing from tiny start-up to handling millions of orders across multiple countries. Next Jago de Vreede and Java champion Bert Jan Schrijver will go head-to-head in a battle comparing two popular microservice frameworks: well-established Spring Boot and new kid on the block Quarkus. Both talks will be presented in English and live streamed via YouTube - RSVP now for an evening of learning and fun! Agenda 19:00 Welcome 19:05 Talk 1 see below 19:45 Break 20:00 Talk 2 see below 20:45 Closing First talk: Scaling Online Groceries with Java by Sander Mak What does it take to run an online grocery store and delivery network at scale? A lot of Java it turns out! In this session well share how Picnics systems evolved while growing from tiny start-up to handling millions of orders across multiple countries.
From migrating to Java 11 right after its release to decomposing our monolith there are many hard-earned lessons we can share. Going cloud-native and reactive? Obviously.
Although not without their own challenges as well see.
Scaling teams also means making tech choices that are less obvious.
For example well show how enabling technologies like the Immutables project and Googles Error Prone offer automated sanity for developers.
Come and learn how the fastest growing online grocery company in The Netherlands builds its systems with Java front and center. About Sander Sander is Director of Technology at Picnic -the Dutch online grocery scale-up- building Java-based systems at scale.

Spring Boot is no doubt a popular choice.
But theres more! Take Quarkus a framework thats considered the rising star for Kubernetes-native Java.
It always depends whats best for your situation but how to choose the best solution if youre comparing 2 frameworks? Both Spring Boot and Quarkus have their positives and negatives.
Lets compare the two by looking at a couple of common use cases in Spring Boot and live coding their Quarkus counterpart.
After this talk youll be ready to get started with Quarkus yourself!
