- gRPC는 구글이 최초로 개발한 오픈 소스 원격 프로시저 호출 시스템이다. 전송을 위해 HTTP/2를, 인터페이스 정의 언어로 프로토콜 버퍼를 사용하며 인증, 양방향 스트리밍 및 흐름 제어, 차단 및 비차단 바인딩, 취소 및 타임아웃 등의 기능을 제공
- Apache Beam은 배치와 실시간 데이터 파이프라인을 개발하고, 다양한 런타임 환경을 지원
- Go-kit는 마이크로서비스 프레임워크이고 다양한 마이크로서비스 디자인 패턴을 지원
- Mongo는 가장 유명한 NoSQL이고 JSON의 관리 및 집계에 유용
- Redis는 가장 유명한 캐시 저장소
- Tracing는 관찰가능성 중 분산추적을 위한 프레임워크를 제공
- Echo는 웹 어플리케이션 프레임워크이고 Air와 함께 auto reload를 지원
- MySQL은 오픈소스 RDBMS
- GORM은 Go언어에서 사용 가능한 ORM(Object Relation Mapping) 라이브러리
- Operator는 사용자 정의 리소스의 컨트롤러 역할을 수행하며, 쿠버네티스 자원에 대한 멱등성을 구현
- Exporter는 다양한 시스템으로부터 메트릭을 수집해서 프로메테우스에게 제공
- RealWorld은 Echo, GORM 등을 사용한 레퍼런스 데모를 제공
4편에서는 Operator를 데모하고 설명한다.
