구분에 대해 명확히 이해가 되지 않는데요,SOA 경우도 서비스 단위 개발이고 Microservice도 그렇지 않나요? 그 규모의 차이가 둘을 구분 짓는 건가요?ex) SOA의 서비스 단위가 숙박 예약 기능이라고 하면Microservice는 숙박조회, 결제 ... 으로 더 세분화 그리고 SOA에서 직접 서비스간에 데이터 교환을 하는 것에서 발생하는 의존 문제로 인해 ESB를 도입했다고 봤는데요, Microservice에서는 API를 통해 서비스 간 통신 시 이런 의존문제가 없을 수 있는건가요? 뭔가 구체적인 예시로 비교해주시면 감사하겠습니다.

안녕하세요 알렉님 강의 잘 듣고 있습니다 실습 마지막에 이미지 파일 업로드 할 때 정상적으로 뜨지 않고 아이콘 모양으로 뜨는데요 문제가 무엇일까요..?

스레드 내에서 여러개의 코루틴이 동작할 수 있다고 하셨는데(8분 51초쯤) 이런 경우에도 프로세스의 힙 메모리를 공유하여 동작하게 되는건지 궁금합니다 :)

마이크로서비스 양질의 내용을 수강중인 학생입니다.지금 kafka source connector와 mariadb를 연결하는 과정에서database url을 찾을 수 없다는 에러가 계속 발생중입니다.혹시 동일한 현상을 해결하신 선배님이 계시거나, 아시는분의 도움을 얻고자 글 올립니다. 일단 db는 정상 실행되고 있습니다.url/user/password/table name까지의 정보는 완전 일치합니다.  증상은 아래와 같습니다. data source 생성 과정 source connector 상태 정보url 정상 유무     

수업자료는 어디에 있는가요?openstack 수동설치 강의도 개강해주세요

 섹션 10 강의를 들으면서 설정값을 바꾼후 busrefresh를 통해 성공적으로 (204)를 반환 받아도 저런식으로 오류가 발생하여 항상 전부 재시작후 실습을 진행중입니다. 어떻게 해결해야할까요?해당 json부분에 이전과 다른 데이터 값을 넣어주면 정상작동합니다. 하지만 제가 알기로는 h2 db의 경우 재시작 할 때마다 데이터가 모두 날라가는걸로 알고 있습니다.spring: datasource: driver-class-name: org.h2.Driver url: jdbc:h2:mem:testdb username: sah2역시 인메모리 방식으로 잘 되어 있는데 왜 모든 서비스들을 전부 종료하고 재시작해야지만 h2내부의 값들이 사라지는지 궁금합니다.

zookeeper의 경우D:\{home}\kafka_2.13-2.7.0>bin\windows\zookeeper-server-start.bat config\zookeeper.properties이대로 실행하면 아래 파바박 뜨면서 tmp에 zookeeper 폴더도 잘 만들어 지는데kafka는D:\{home}\kafka_2.13-2.7.0>bin\windows\kafka-server-start.bat config\server.properties아무것도 안뜨고 그냥 D:\{home}\kafka_2.13-2.7.0>으로 넘어갑니다 tmp에 폴더도 안 만들어지고요. 딱히 에러가 발생하지도 않습니다. java는 jdk 11.0.2사용 중이고 버전에 문제 없어 보이는데 왜 이러는 걸까요?

이번 강의의 native 와 기존에 처음부터 보여주신 uri : file///~~~ 의 방법과 크게 다른점이 뭔가요? 다른점이 없는것 같은데요...

 @Configuration @EnableAspectJAutoProxy public class MetricsConfig { @Bean public TimedAspect timedAspect(MeterRegistry registry) { return new TimedAspect(registry); } }해당 config 파일을 추가해주세요.

window11 / 23.08.09 기준으로 kafka connect 버전을 7.1 버전으로 사용하시길 바랍니다.해당 강의의 6.1 버전에서 properties 경로를 못찾아서 버전업을 했더니 해결 했습니다.

mariadb 최신버전 사용시 Dockerfile 그대로 작성시 실행 에러가 발생합니다.저는 sql 을 백업해서 스키마랑 테이블 새로 만들도록 수정해서 해결했습니다.추가로 실행후 mysql 접속도 mysql 명령어가 아닌 mariadb 로 작성하셔야 됩니다.mariadb -h127.0.0.1 -uroot -pmysqldump -u root -p mydb > mydb.sqlFROM mariadb ENV MYSQL_ROOT_PASSWORD test1357 ENV MYSQL_DATABASE mydb COPY ./mydb.sql /docker-entrypoint-initdb.d/ EXPOSE 3306 

강의자료를 볼 수 있는 github가 있었던 것 같은데아무리 찾아도 없네요.강의자료 다운 혹은 볼 수 있는 주소 좀 알려주세요.

Singleton Pattern 기초 강의 내용에서 질문드립니다.Bill Pugh Solution (Java) 부분에서 Holder 클래스를 보시면private static final DBHandler INSTANCE = new DBHandler();라고 되어있는데, 이 경우 getInstance() 함수를 통해 Holder.INSTANCE 가 호출이 되어도 fianl 로 선언되어있어 한번만 선언되기 때문에 signleton 으로 사용 가능하다는 말씀이 맞는지 궁금합니다.
