GRILL MEETUP oraz dwa tematy! Saga Pattern oraz Serverless!

Serdecznie zapraszamy na już #17 spotkanie GRILL MEETUP zielonogórskiej grupy DEV@ZG oraz ZG JUG, sponsorowane przez firmę ADB jako głównego sponsora, oraz firmę GlobalLogic, która udostępnia nam rzutnik.

Tak, tak - na rozpoczęcie sezonu robimy wspólnie z ZG JUG, tak aby zacząć sezon we wspólnym DEV gronie.

Spotkamy się w otoczeniu przyrody, pod zadaszeniem na świeżym powietrzu, z zapachem grilla oraz piwem.

Przyjeżdża do nas Andrzej Krzywda oraz Robert Pankowecki z bardzo ciekawymi tematami.

Zapowiada się więc rewelacyjnie jak na początek sezonu!

Poniżej opis spotkania (w języku angielskim).

Pamiętajcie, aby na samym dole opisu przeczytać jeszcze ogłoszenia organizacyjne.

OPIS SPOTKANIA

Temat#1: Saga pattern

As you build more complex solutions, you may find that certain interactions in your system depend on more than one bounded context. Order, Inventory, Payments, Delivery... To finish one feature often many sub-system are involved. But you want the modules to be isolated and independent. Yet something must coordinate their work and business processes. Welcome the choreographer - the Saga Pattern a.k.a. Process Manager.

What we try to do everyday in our 8 year old application is to split it into multiple independent parts of application called bounded contexts. But many features requires them to communicate with each other. We do it by publishing domain events and having objects called sagas orchestrate the processes which touch multiple parts of the application. We work on a ticketing&e-commerce application that sells thousands of tickets every day. The insights will be based on real-world battle-tested examples.

I think a lot of talks describe a ways to split your application horizontally with more layers such as presenters, decorators, service objects, repositories etc... But I think much bigger problem is how to split your application vertically into more isolated sub-systems. This is what I would like to show and discuss how we use domain events and sagas so that those sub-systems can communicate between each other.

Temat#2: Serverless

I was sceptical about microservices when it became the buzzword of the decade. However, over time, when I learnt more about applying DDD in bigger apps, I found that DDD and microservices can be a great (though challenging) combo! Now, we have another buzzword growing popularity - serverless. I’m not sure it will survive another year or two, but it seems to be a big thing in the deployment world - how does it connect to DDD and microservices? Let’s find out!
