Great presentation by Gegor. Fully packed with great concepts based on history, experience, practical aspects explaining many key dimensions such as the what, why, when, who, how behind patterns and technologies. Helping you see things through lens that help you identify and make decisions based on trade-offs. Watched it twice already and planning to watch it again. Thanks Gregor for putting time and effort to share knowledge in very clear and concise way in a very short time window.
Key nuggets of information explained with such simplicity. We all are using these patterns but when it comes to explaining it in simplistic terms we get caught in buzzwords. This was such a refreshing listen. Thanks for such a refreshing and insightful talk. Thanks for sharing this!!!
A lot of good stuff in the talk. Yet I feel the comparison of commands vs. events around 27:00 falls a bit short. Gregor says using an event vs. a command is just "shifting a little bit of the burden from the left to the right". This seems to ignore that commands will usually expect a response. Commands can fail, so the sender will want to know if it actually succeeded or not. And if it failed, it'll be the senders problem to deal with this failure. Events, however, are "fire and forget". The sender just emits information about a fact, and won't want to hear back from any subscribers. So while he's of course right that this doesn't magically remove any coupling, the overall flow of messages will be very different, depending on whether you work with commands or events.
@@awssupport Oh, I don't think that's necessary. It's just a suggestion to Gregor, I thought it could be a perspective he might find interesting, and maybe even like to add in future comparisons. Thanks for replying, though!

Thanks for sharing, Lutz! I've made sure your feedback has reached our Events team for review. ^RM

Great talk. Golden information digested nicely.
Awesome presentation, as always! So unfortunate that sounds drops for few seconds every few minutes...
Small startup like AWS can’t be expected to afford all the latest audio tech.
