We are talking about Event Driven Architecture examples today. There was an event in London a few weeks ago, called EDA Day. It was organised by GOTO with a lot of AWS contributors. It was neat because it was one day focused on event driven architectures. It showed the coming together of a 15 to 20 year old pattern of EDA, plus serverless. And all the bigger services on top of that, like Eventbridge and Step Functions.

Gregor Hohpe's Keynote

Gregor Hohpe did the keynote talk: 'I made everything loosely coupled. Does my app fall apart?' Gregor is an AWS enterprise strategist. And he talked about the event landscape and the complexities behind event driven and architecture. He had a diagram called: 'A calls B'. It looked pretty simple until you get to the million things you need to think about when A calls B!

Serverless Espresso

Julian Wood, Ben Smith, and a few others from Serverless Land, put together a demo called Serverless Espresso. You scan a barcode and through an event driven step function, event bridge sequence, you can order a coffee from your phone. So look up AWS labs, to see Serverless Espresso. It's well put together to show how you build an event driven architecture from the ground up.

Ben Ellerby - Minimal Viable Migrations

He worked in Theodo and is an AWS Serverless Hero. He has a thing about Minimal Viable Migrations. A lot of people think event driven is a greenfield or brand new thing. But he had a great talk about existing architecture and going event driven. He talked about doing a small part of your architecture and going bit by bit. By using an incremental model.

David Boyne - Awesome EventBridge

David Boyne joined AWS and does ‘Awesome EventBridge’. He has open source projects. And he does a great talk on 'Thinking Event First'. How to approach events and get your schemes right. And really think about your domain model and lock it in from day one. Look up his resources on ‘Awesome EventBridge’.

Marcia Villalba - FooBar Serverless

Marcia Villalba is a developer advocates at AWS. She's got great content on good practices and getting started. She has a really nice way of explaining these concepts. Check out her FooBar Serverless YouTube channel. There is tons of developer friendly content from beginner to more advanced.

Lego Talk - Sarah Hamilton and Sheen Brisals

The last one to talk about is Lego. They sponsored the event. And they had two talks. Sarah Hamilton is one of the software engineers and she gave a really good talk about the advanced techniques they're using in their event driven architecture. My friend, Sheen Brisals was speaking as well. They have a fantastic story, which is well worth listening to. It's about how they moved to an event driven serverless architecture. There's a socio-technical element to this. How you organise your teams and the attitude is what I would call a core engineering competency and mindset. As opposed to an architectural pattern. Lego tells their story brilliantly.

Product Leader panel

The event ended with a panel of product leaders from Eventbridge, Step Functions and MongoDB. It was a really relaxed panel. Emily Shea, who we know well, was there. She works in go to market for serverless. It was a relaxed chat. No one was pushin
