Hi, Spring fans! Welcome to another jam-packed weekly roundup of This Week in Spring.

I've got a few upcoming speaking engagements you might be interested in. I'll be speaking (virtually) at the San Francisco JUG on June 24th at 6:30 PM. Join me!

Can't make it to the (virtual) SF JUG appearance? On June 30th, VMware Tanzu (where the Spring team lives) will be hosting one of my workshops, also on Reactive Spring. I'm going to cover tons of stuff: R2DBC, Reactor, Spring WebFlux, Spring WebFn, reactive Spring Data for SQL and NoSQL, RSocket, reactive security, reactive service orchestration, and composition patterns, and more. This is going to be at an ideal time for EU timezones, so please register now.

I'll be presenting about Bootiful Testing for the upcoming Jetbrains Technology Day for Java on July 10th, 2020 at 10 am-11 am CEST.

I'll also be doing an upcoming webinar on Wavefront-powered observability with Tanzu Wavefront team member Sushant Dewan on June 24th at 10:00 AM PST. You don't want to miss this!
