Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm fresh of the amazing Spring Connect São Paulo event and speaking with some customers, and now I'm in beautiful Rio de Janeiro soaking up the winter rays by he beach, connecting with people in the community, and delivering a (virtual!) 2 day live training course for O'Reilly on building cloud-native Java-based applications. In less than two days I'll be home for the first time in almost a month to celebrate the 4th of July. If you're in America, let me be the first to wish you a happy holiday. As usual, we've got a ton of things to dive into so I'll leave you to it. Let's get going.

• Our very own Mario Gray does a wonderful job looking at reactive authentication and authorization with Spring Security
• Interesting insight from the Zipkin project twitter handle: 1) authorization services often blamed for latency, even though getting security services in your traces is a win for transparency. Also, errors are two-sided: ideally, visualize HTTP 400 as success from server point-of-view to better aim blame.
