Event Driven Architecture ?? ??????? ?????? ?

Event Driven Architecture (EDA) ?? ??????? program ??? flow ?? event ????? determine ??? software design pattern ????. ????? event ???? ??????? ????? ??? program ??? ??????? state change ???? ??????? update ????. ????????? ?????? shopping cart ??? item ???? add ??? ?? ???? ???????.

?? EDA ???? decouple ???? ????? services ???? communicate ????? events ?????? ?????. ? ???? ?? communication ?? ?????? event bus ???? ????.

???? ??? ???? ?? architecture ??? ????? key components ???.

1. Event : EAD ?? core ?? ???? events. Event ???? ??????? program ??? state ??? ???? ??? significant change ???? ?? button click ???? ??? occurrence ???? ????? ???????.
2. Event Producer : Event generate ?????? ?? event producers ?? ?????.
3. Event Consumer : Events receive ???? ??? ? event ??? ???? act ??? components, event consumers ????? ?????????.
4. Event Channel : Event ???? producer component ??? ??? consumer component ??? transmit ??? medium ?? event channel ?? ?????? ????????. ??? RabbitMQ , Apache Kafka ??? message broker ???? ?? event bus ???? ????? ???????.
5. Event Processor : ?? component ????? event ?? process ???? filtering, transforming ?? data aggregating ??? operations ?????.

??? ???? ???? EAD ?? use cases.

1. ??? application ??? ????? volume ??? event handle ????? ?? efficiently scale ????? ?? ???? EDA ????? ??? components ??? independently event process ????? ?? scale out ????? ?? ??? ?????.
2. Live analytics, monitoring systems ?? financial trading systems ??? real-time ?? near-real-time data processing ???? ????? ?????? ?? architecture ?? useful.
3. ???? components independently develop, deploy ?? update ????? ?? system ???? ????? ?? ????? ?? architecture ?? loosely coupled ???? ??? use ????? ???????.
4. Servers ?? location ??????? components spread ???? ????? distributed system ??? component ???? communicate ????? ?? event process ????? ?? architecture ?? useful.

??? ???? ???? EDA use ????? ??? ???? ?????? ???.

1. Simple Applications : Limited scalability ???? ????? simple application ??? EDA ????? ?????? complexity ???? add ????? ???????.
2. Strict Transactional Consistency : EDA ?? ???????? eventual consistency model ????. ?? ???? strict ACID transaction ????? system ???? ??? ????? suitable ??.
3. Tight Latency Requirements : Event handling ?? propagation ?? overhead ?? ???? extremely low latency requirements ????? system ???? ??? suitable ??.

??? ???? ???? EDA ?? ????? benefits.

1. Scalability : Consumer ?????? ???? distribute ???????? ????? volume ??? events handle ?????? ?? architecture ??? ???????. Services individually scale ????? ??????? microservice ??? architecture ?? ??? ????? use ?????.
2. Decoupling : ??? ???? ??? ?? component ???? ??? change ???? ???? component ???? directly impact ?????? ??. Loosely couple ???? ?????? system ????? flexible ???? modify ????? ????.
3. Real-time processing : EDA ?? ????? high-throughput, low-latency event handle ?????? ??????? ???? immediate responses ????? ?? fraud detection, stock trading ?? real-time analytic system ??? ??? ????? ?????.
4. Resilience : System ??? ?? component ???? fail ???? ????? components ??? ????? ??? ???? ???? ???????.
5. Enhanced Maintainability : ???? ????? modular approach ?? ???? maintainability ?? ????. Individual components ?? debugging, testing ?? deployment ????.

??? ???? ???? EDA use ??? real world application ????????.
