• 18:30 AWS & Serverless Case Study

- czyli krotka prezentacja o tym, jakie problemy i dylematy spotkalem podczas budowy aplikacji opartej na AWS Lambda i Serverless framework, co bylo dla mojego zespolu najwiekszym wyzwaniem i na co trzeba uwazac przy pisaniu takich aplikacji w oparciu o rozwiazania chmurowe.

Chetnie podziele sie swoimi doswiadczeniami i przemysleniami i postaram sie udowodnic ze do zabawy z chmura nie potrzeba grubego portfela a tylko troche checi

• 19:15 Time-based domain events - how to deal with time on Kafka

Description:

Time-Based Domain Events are a niche in the studies of business modelling. Moreover, there is no straightforward answer to whether technology would be appropriate to support them efficiently. Dealing with time very often proves to be a tough challenge. Especially bearing in mind distributed computing and various aspects of it. However, it is very likely that in your Domain, there is a plethora of Domain Events triggered by a precisely defined point in time.

The purpose of this presentation is to tackle difficulties in a proper and reliable design in order to fulfil business needs where Time-Based Domain Events are concerned. In the first place, some brief overview of a general idea is given. Secondly, the focus is put on the real requirements such as interaction with domain models. Next part includes technical exploration of solution backed up with Kafka. It is hoped that this presentation will shed some light on technical aspects of Time-based domain events as well as inspire interested parties to further research.

Requirements: basic knowledge of DDD, Kafka, Redis
