Event mesh api meetup AsyncAPI Singapore
1) The document discusses how event-driven architectures and asynchronous APIs can make interactions more responsive and agile. It defines an event and provides examples of how events are generated from user actions. 2) A key benefit of event-driven systems is improved responsiveness through asynchronous processing and deferred execution. This allows isolating performance-critical paths from less time-sensitive operations. 3) The document advocates for a microservices approach powered by an event mesh to route events. This enables agility, scalability, and parallel processing while maintaining eventual consistency.

Editor's Notes
- #3 - And contributing significantly to achieving these business objective is becoming event driven, which is what Gartner has been saying - where Events enable an organization to become more realtime, agile, connected & distributed To do this IT architectures need to move from being data at rest centric to becoming event centric IT groups need to transition from being custodians of their firms data at rest to providing a nervous system if information in motion and and democratizing access to these events in realtime. That’s what Gartner says
- #5 I assume most of you flew here to Orlando so you would have scanned your boarding pass. Anyone here named Samantha? Seems like a minor thing – a passenger scanning a boarding pass. Who would care about that? Well – let me walk you through some examples of how this event is interesting to an airline and it’s a subset of the examples that an architect at one of our clients used to “sell” being driven to his business Keep in mind that being “event driven” means distributing events as they happen to any system that wants it – so very typically making information available across organizational silos and LoBs
- #6 Passenger Boarded Flight Planning extrapolates new BoardingComplete time and issues an EstimatedBoardingComplete event Received by airOps which cancels runway slot and books new one Received by groundOps to know current ground team won’t be done ontime so schedules new crew for their next gates Received by PassengerTripMgmt – who realizes Samantha will miss her connection and rebooks her on another flight ==> and tells her
- #7 This architect also explained to his business about the time value of events Businesses understand the time value of money – where $1 is worth more today than it is in a year from now Events are similar: Understanding what is happening in your business today is more valuable than understanding tomorrow what happened in your business today
- #10 The Incredibles Or better yet, I’ll give you continuous progress updates on our trip so you constantly know our status Then also I say it once and all 3 of you kids or 6 kids or whatever all get this information – I don’t have to tell you individually & you don’t have to ask me individually. This scales much better and for sure makes for a much quieter & more enjoyable ride!
- #13 When change is needed, it can’t happen in just one part of the company, it needs to happen in all aspects of the company Introducing EVENT HORIZON as a framework to drive change across our entire company This isn’t just marketing words It’s looking at every part of our company and embracing change To prove it to you we will go through each pillar here and outline how we will be embracing change starting with the unveiling of our new SOLACE PLATFORM!!!!!!!!
- #15 Insert animated diagram on the next slide, let’s have it play on a loop while Shawn explains the concept.
