5 Workload 에맞는전략 거의 60% 가멀티클라우드환경을사용중이거나사용예정 여러분의조직은현재 ( 워크로드 ) 운영을위해다양한인프라기술환경을사용중인가요? 특화된비즈니스프로세스 55% 5% 15% 직원생산성 35% 5% 19% 데이터처리, 분석및비즈니스인텔리전스 52% 19% 14% 네아니오, 계획이있음아니오, 고려중 Source: Liam Eagle, 451 Research, Voice of the Enterprise: Cloud, Hosting and Managed Services, Workloads and Key Projects - Quarterly Advisory Report, May 15, 2018.

6 Public Cloud 도입계획수립 퍼블릭클라우드제공자선택시가치구분! 표준운영환경 (SOE) 및어플리케이션플랫폼 (public & private) 에대한인증된지원이있는지확인! 프라이빗클라우드와같은데이터스토리지, 백업및복구옵션에대한고려! 회사의보안정책및규정에따라어플리케이션과데이터를퍼블릭클라우드로이동할수있는지확인! 프라이빗클라우드플랫폼과선호하는클라우드공급자를포함해서통일화된관리솔루션을조사하거나개발

7 Private Cloud 이점 데이터, 비용및위치에대한완전한제어 CONTROL REDUCE COST SECURITY AGILITY AVAILABILITY 비즈니스요구에맞게생성및수정 전반적인인프라및운영비용절감 앱과데이터의보안및제어강화 비즈니스속도에맞춰 IT 제공 여러팀에서어디서나이용가능한서비스

8 클라우드에서컨테이너를사용하는이유 컨테이너를위한전략이필요한이유! 데브옵스와마이크로서비스와같은최신소프트웨어개발접근을지원하기위함! 표준운영환경과다양한리눅스버전을지원하기위함! 인프라로부터앱을분리하기위한이식성을생성하기위함 컨테이너는다음을지원하기때문에하이브리드클라우드환경에서중요 : 마이크로서비스와전통적인애플리케이션 개발에서운영까지의일관된배치 물리및가상화환경뿐아니라클라우드간의애플리케이션이식성

9 What is Containers? 소프트웨어패키징 + 자원격리 Hypervisor/VMs - Abstraction of a FULL SYSTEM (hardware, BIOS, OS), Containers - Abstraction of User Space and SHARE the same OS, services, and hardware OS 가상화기술 호스트운영체제상의애플리케이션격리 변경불가능하고단순하며가벼움 손쉬운배포 호스트시스템간호환성 멀티호스트상의컨테이너에대한오케스트레이션 / 관리필요 마이크로서비스아키텍처의도입촉진 HIGHER DENSITY Virtual Machine Application OS dependencies Operating System Infrastructure VM Isolation Complete OS Static Compute Static Memory High Resource Usage Container Application OS dependencies Container Host Infrastructure Container Isolation Shared Kernel Burstable Compute Burstable Memory Low Resource Usage

10 Why Containers? Microservices, Instantaneous restart time, 자원효율성, 자원격리, 호환성, Auto Scale VM Type X VM Type X VM Type X Container Container Container Application Application Application Application Application Application Application Application Application WAS WAS WAS WAS WAS OS WAS WAS GuestOS WAS GuestOS WAS GuestOS Container Engine OS Hypervisor X Bare Metal Virtualization Any Infrastructure 자원 (CPU, Memory) 격리불가 OS 간호환성문제 Application 자동확장불가 자원 (CPU, Memory) 격리 하이퍼바이저 /GuestOS 부하단점 이기종 VM 기술간호환성문제 Application 자동확장불가 자원 (CPU, Memory) 격리 표준컨테이너기술로호환성제공 Application 자동확장가능 하이브리드클라우드환경

11 Container 표준 표준기술을사용하면벤더종속을벗어남 Established in June 2015 Create Open Industry Standards around Container Formats and Runtime A lightweight, OCI-compliant container runtime

12 Container Ecosystem Industry leaders unite to create open standards and governance for container format and runtime Create and drive the adoption of a new computing paradigm that is optimized for modern distributed systems CRI-O is an implementation of the Kubernetes CRI (Container Runtime Interface) to enable using OCI (Open Container Initiative) compatible runtimes.
