Building Serverless Event Bridges… 🌉

Welcome to Issue #46 of Off-by-none. I’m so happy that you’re here! 😃

Last week, we pondered how companies adopt serverless and previewed AWS Summit New York. This week, we take a deep dive into the new Amazon EventBridge service and share some amazing stories, tutorials, and content from the serverless community.

There is a lot to get to this week, so let’s get to it! 🏃‍♂️

When you’re wondering why EventBridge is such a big deal #NoMoreWebhooks…🤓

Last week Thursday was very exciting for all us serverless nerds out there. Werner Vogels introduced Amazon EventBridge in his keynote, and several people quickly took notice of how powerful this new service is. Besides this excellent post by Mike Deck, a few others had some rather good things to say about it:

Amazon EventBridge: The biggest thing since AWS Lambda itself
Jared Short made this rather bold claim, but I wholeheartedly agree. Yes, CloudWatch Events has been around for awhile, but custom event buses and partner integrations elevate events to first-class citizens within the AWS ecosystem. This is important.

Why Amazon EventBridge will change the way you build serverless applications
Paul Johnston gets it too. He also said that EventBridge is “the most important release for serverless applications since Lambda.” CloudWatch Events was a clever way to coordinate custom events without needing SNS or Kinesis, but now Paul says, “EventBridge has become a central pivot to a serverless applications on AWS.”

There have also been a few posts that show it in use:

If you want even more insights into what you can do with EventBridge, listen to the latest episode of Serverless Chats (Episode #5: Event-Driven Applications using Amazon EventBridge with Mike Deck) where Mike Deck and I chat all about it.

Serverless Star of the Week ⭐️

There is a very long list of people that are doing #ServerlessGood and contributing to the Serverless community. These people deserve recognition for their efforts. So each week, I will mention someone whose recent contribution really stood out to me. I love meeting new people, so if you know someone who deserves recognition, please let me know.

This week’s star is Erez Berkner (@erezberkner). Erez is the CEO & co-founder of Lumigo, a startup focusing on serverless application monitoring. Erez is always out there spreading the word of serverless, whether through Twitter and blog posts, or through his numerous speaking engagements and interviews. Since the beginning, Erez and Lumigo have embraced and contributed to the growth of the serverless community, and has used the Lumigo platform to engage and educate people on the benefits of serverless. It doesn’t go unnoticed. Thanks for all you do, Erez!  🙌

Final Thoughts 🤔

There were a lot of exciting serverless announcements this past week, plus a very successful ServerlessDays London event, so congrats to the organizing team over there. But there were also lots of dumb and incredibly hurtful things said that are becoming normalized in our culture (and I’m not just talking about that 10x Engineer nonsense). So without getting political, I’ll simply make a naive plea and ask that we all try to be better people, or in the words of Bill & Ted, “be excellent to one another.”

I’ll leave you with this excellent piece by Emma Wedekind: 101 Tips For Being A Great Programmer (& Human).
