Managed Container-as-a-Service Serverless Deployment remove the needs for us to manage the underlying infraStructure. Simplified Application Management. Out-of-the-box High availability & Scaling "Pay what your Users use" business Model. 서비스를 제공하는 vendor 입장에서는 'do not waste resources like cpu / ram for no reason.' 즉 '내가 사용하는 리소스'에 대한 비용 지출이 아니라, '내 프로덕트를 이용하는 사용자가 쓰는 리소스'에 대한 비용 지출이 이루어진다. inste..

Presentation Layer Overview Presentation Layer : 사용자와 시스템 간, business logic, stored service 간 데이터 flow를 말한다. 간단히 말해 Networking. Presentation Layer : Network Configuration Networking 에서 가장 중요시해야 할 건 Location. 이게 latency 차이를 만드는 핵심이기 때문. Distributed network일수록 outage tolerance가 강해지지만, round trip time is slower between distant elements 문제 때문에 performance limitation은 반드시 존재한다. 미국 - 유럽 간 통신은 1초당 최대 6..

Data Layer Overview Storage / retrieval of data를 다루는 영역. Storage / retrieval 영역인 database / file system뿐만 아니라 access method; SQL and API 등등을 포함한다. 하지만 transport of data는 다루지 않음. (Into, around, out of the system) transportation 부분은 presentation layer module에서 다룬다. Data Layer Design : Classifying and Characterizing Data 사용자 입장에서 중요한 건 Data integrity. Underlying tech에는 관심 없고, data loss / data corru..

Business_logic Layer Design OverView Business Logic = code that implements business logic (Computer Science에서의 정의) that determines what happens to data. = processing. Ex) 비행기 티켓 예매라고 하면, 예매 인터페이스가 앱이건 키오스크건 상관없이 ‘티켓 예매’라는 데이터 처리는 동일하다. 이게 business logic. Microservices = specific kind of Service Oriented Architecture (SOA) -> leverages small, stateless processing for improving scalability and res..
