Openshift, Openstack 이해

OpenShift와 OpenStack은 모두 오픈 소스이며 Red Hat Inc.에서 유지 관리하는 클라우드 관련 기술입니다. 오픈스택이란 서버를 클라우드로 전환, 리소스 할당을 자동화하는 데 사용할 수 있으므로 고객은 무엇보다도 VPS, 블록 스토리지, 개체 스토리지와 같은 가상 리소스를 프로비저닝할 수 있습니다.
반면에 OpenShift는 Platform-as-a-Service를 제공하는 기술입니다. AWS, Google Compute Engine 등과 같은 클라우드 서비스에서 실행되고 개발자에게 제공할 수 있는 것입니다. (가상 또는 물리적) 문제를 일으키지 않고 앱을 배포하고 테스트하는 쉬운 방법 서버. 기술적으로 OpenStack을 사용하여 유지 관리되는 클라우드 서비스 위에서 OpenShift를 실행할 수도 있습니다. 그러나 그것들은 서로 분리되어 사용될 수 있는 핵심적인 독립 기술에 있습니다.

이제 기본적인 차이점을 알았으므로 더 깊이 파고들어 그들 사이의 유사점과 차이점이 무엇인지 알아보겠습니다.

OpenStack은 일반적으로 KVM, Xen 또는 VMware와 같은 하이퍼바이저를 사용하여 가상 머신을 가동합니다. 해당 머신에서 컨테이너를 실행할지 여부는 전적으로 귀하의 선택입니다. 그러나 하이퍼바이저는 일반적으로 OpenStack과 함께 사용됩니다.

메모: OpenStack은 컨테이너화 지원도 제공하며 VPS와 유사하게 더 많이 사용되며 선택 사항입니다.

반면 OpenShift는 Kubernetes의 핵심 개념을 활용하는 컨테이너 중심 모델입니다. 조직이 애플리케이션을 개발하고 배포할 수 있도록 깔끔한 방식으로 패키지화합니다. 구름. 베어 메탈에서 실행되거나 가상 머신에서 실행될 수 있지만 항상 그 위에 컨테이너를 사용합니다. 그들이 사용하는 컨테이너화 기술은 거의 전적으로 Docker입니다.

분산 시스템
다시 말하지만, OpenStack은 독점적인 분산 시스템이 아닙니다. 전체 데이터 센터를 제어할 수 있지만 Kubernetes 클러스터만큼 글로벌하지는 않습니다. OpenStack의 여러 원격 설치를 단일 분산 시스템으로 전환하려면 많은 추가 소프트웨어 계층이 필요합니다. 분산 스토리지 스택을 구축하는 데 사용할 수 있는 Glusterfs 및 Ceph와 같은 분산 스토리지 기술을 제공할 수 있지만 특별히 의존하지는 않습니다.


반면에 OpenShift는 본질적으로 분산 시스템입니다(Kubernetes를 통합하기 때문에 의미가 있습니다. 그 안에) 그리고 그것은 분산 시스템이기 때문에 반드시 소수의 작업자를 제어하는 ??하나 이상의 마스터 노드가 있어야 합니다. 노드. Red Hat은 이러한 노드 간의 통신을 용이하게 하는 네트워킹을 위한 적절한 계층을 제공하며 사용 Glusterfs 및 Ceph와 같은 분산 스토리지

IaaS 및 PaaS
OpenStack은 IaaS(Infrastructure as a Service)를 제공하는 데 도움이 될 수 있습니다. DigitalOcean, AWS, Microsoft Azure 및 Google 컴퓨팅 엔진과 같은 클라우드 VPS 제공업체에 일반적으로 귀속되는 서버를 관리하고 서비스를 제공합니다. 조직은 자체 서버를 구입하고 개인 정보 보호 또는 경제적 문제를 위해 개인 데이터 센터를 설정하기로 결정할 수 있습니다. 이러한 서버를 실행하기 위해 자체 관리 유틸리티를 개발하는 대신 해당 서버에 OpenStack을 배포하고 조직의 서버로 전환할 수 있습니다. 프라이빗 클라우드.

반면 OpenShift는 Platform as a Service를 제공합니다. 개발자가 앱 개발 및 테스트에만 관심이 있는 Google App Engine에 익숙하다면 전체 서버 구성은 중요하지 않습니다. Google은 클라우드에서 실행되는 앱을 컨테이너화하기 때문에 가능합니다.

OpenShift가 조직에서 개발 중인 애플리케이션을 컨테이너화할 수 있는 것과 거의 동일한 방식입니다. DevOps 팀은 전체 CD/CI 파이프라인을 설정하고, 멋진 A/B 테스트를 수행하고, 문제를 추적하고, OpenShift를 사용하여 다양한 개발, 테스트 및 배포 단계 간의 흐름을 간소화할 수 있습니다.

새 프로젝트를 만들고 사용하려는 언어(Python, Node.js, Go, C#, Java)를 선택하고 다양한 권한을 가진 사용자를 추가하고 OpenShift는 모든 종속성이 충족되고 모든 라이브러리와 프레임워크를 사용할 수 있으며 모든 권한이 존경합니다.

OpenShift, OpenStack 및 하이브리드 클라우드
OpenStack 위에서 OpenShift를 실행할 필요는 없지만 원하는 경우 함께 사용할 수 있습니다. 클라우드 서비스를 사용하여 다양한 데이터 센터에 VPS를 할당하는 것과 거의 동일한 방식 제공자에게 OpenShift를 설치한 다음 앱 작업을 시작하면 동일한 작업을 수행할 수 있습니다. 오픈스택.

실제로 애플리케이션을 퍼블릭 클라우드 서비스(예: AWS)와 프라이빗 클라우드(OpenStack을 사용하여 구축) 간에 실행하도록 분리할 수 있습니다. OpenShift는 앱에서 비공개로 유지하려는 부분(예: 사용자 데이터)이 프라이빗 클라우드에 유지되도록 합니다. 이는 개인 노드에서 데이터 저장소 관련 포드를 실행하도록 OpenStack을 지정하여 쉽게 달성할 수 있습니다.

나머지 나머지 부하는 공용 클라우드에서 처리할 수 있습니다. 파드와 노드의 의미가 확실하지 않다면 튜토리얼을 확인하세요. 쿠버네티스 개념 그리고 그것이 어떻게 보이는지 생산.

결론
두 프로젝트 모두 Red Hat Inc.의 훌륭한 이니셔티브입니다. 그리고 그들은 마이크로소프트, 구글, 아마존이 클라우드 시장을 자유로이 지배하는 대신 경쟁자를 찾아야 한다고 확신합니다.

Openshift vs Openstack: An Easy Differentiation in 3 Points

 

Introduction

Choosing the best open-source platform that can help with your journey into the cloud can be challenging. Why? You have many choices, and this number is only going to get bigger in the years to come. Two key players in this market are openshift and open stack. That means the search for openshift vs OpenStack is extremely high! It is important for you to understand where each has an edge. Also, to ensure that your business chooses the right technology for the completion of tasks. 

1. What is openshift
2. What is open stack
3. Differences between the two

1) What is openshift     

So, what and why use openshift? Openshift comes with a web console, command-line tools and IDE support. The web console is meant to simplify the overall application development process. Managing resources and controlling applications is extremely simple using the web console of openshift. Also, openshift supports continuous integration with third-party tools like Jenkins. This means, all your cloud deployments can be automated and performed in iterations using openshift. In case you are using openshift for the first time, it’s prebuilt templates will be highly useful and recommended. Open shift management becomes simple and seamless with these templates. 

2) What is open stack

On the other hand, open stack works with components. There are five components to choose from. Nova, Horizon, Neutron, Cinder and Keystone are the five open stack components that can help you with open source cloud development. Nova is a component that takes care of resource provisioning through bare metals and VMs. Neutron is necessary for network connectivity and provisioning. Cinder is a storage facility that supports with the mounting of devices. Horizon is a dashboard that allows users to manage all their openstack components. Keystone is a security component for authorisation and authentication.

3) Differences between the two

The battle between red hat openshift vs openstack is rather interesting. Here are a few major differences between these platforms. 

Open stack doesn’t invest on containers. Much of the operations in openstack are handled using VMs. This includes VMWare Hypervisor, Xen and KVM. Openshift relies on containers. It is important for you to understand dockets and Kubernetes if you want to use openshift. 

Openstack had distributed data Centers, which are controlled from a single point. It never relies on a global cluster of storage or resources. Ceph, Glusterfs and few other third-party tools are used to manage storage. Openshift uses Kubernetes to handle the clusters. It strongly relies on this technology. Master nodes are created to manage the other distributed nodes. The worker nodes are responsible for communication in the network layer. 

Both openstack and openshift are meant to function well with the cloud. Openstack is designed to work with all cloud service providers, ranging from azure to AWS to Google Cloud. On the other hand, openshift is a platform as a service facility. Though it works seamlessly as a PaaS, it works independently. This is why openshift can be used to create native cloud services. These services can be hosted along with any cloud resource. 

These are a few of the major differences between openstack and openshift. They are designed uniquely to cater to the needs of open source deployment. During deployment, in both these environments, you need to stress on storage and how data is shared across resources. And, you must invest in automation of devices, processes and resources in both these platforms. 

Conclusion 

On the whole, openstack, openshift and any other cloud deployment platform is meant to make your business operations easier. These are enterprise-level solutions, which have taken care of automation, security and even continuous integration with tools like Jenkins. When you pick openstack or openshift, ensure that it blends with your current technologies.
