From a micro-software process or service to a giant application, a single container can run them all. All the files needed to execute, binaries, configuration files are contained in one container. Container sets, as opposed to server virtualization, do not contain operating system images, so they are lighter and more portable, at a lower cost.\u00a0<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Two of the most famous container development platforms are <strong>OpenShift and Kubernetes<\/strong>. When discussing OpenShift and Kubernetes, you may hear the term \u201ccontainerization.\u201d But have you ever considered what it means and how it is used? According to a popular definition, containerization is \u201cthe packaging of separate applications to create, manage, and deploy them more efficiently across multiple infrastructures.\u201d \u201cContainerization\u201d allows businesses to be more flexible and scalable. Therefore, application development is more efficient.

It is really useful for creating Cloud-based applications and is an open source and very user-friendly cloud platform to develop, test and run applications before deploying them to the cloud. . OpenShift allows developers to use an integrated development environment (IDE) to create and deploy Docker-formatted containers, which will then be managed by the Kubernetes platform. OpenShift can handle applications based on Node.js, Ruby, Python, Perl, and Java. The scalability of OpenShift is one of its most important aspects, as it allows users to use it to support applications built in many different languages. Containerized applications can be optimized automatically or manually using the platform.<\/span><\/p>\n<p style=\"text-align: justify;\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-14608 size-full\" src=\"https:\/\/gcloudvn.com\/wp-content\/uploads\/2023\/07\/openshift_vs_kubernetes_2.jpg\" alt=\"OpenShift Vs Kubernetes \u2013 Key Differences 2\" width=\"600\" height=\"356\" srcset=\"https:\/\/gcloudvn.com\/wp-content\/uploads\/2023\/07\/openshift_vs_kubernetes_2.jpg 600w, https:\/\/gcloudvn.com\/wp-content\/uploads\/2023\/07\/openshift_vs_kubernetes_2-18x12.jpg 18w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Kubernetes_la_gi\"><\/span><b>What is Kubernetes?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Over a decade ago, Google developers created Kubernetes, a container-as-a-service (CaaS) technology. Kubernetes is an open source mobile container solution that allows developers to automate deployment, management, scaling, and networking between containers. It supports large-scale management of containerized, distributed applications. You simply tell Kubernetes where you want your software to run, and the platform handles all the deployment and management for you. Kubernetes, now part of the Cloud Native Computing Foundation, allows application developers to take advantage of features such as self-monitoring, process automation, container balancing, storage orchestration, etc. and simple discovery, Kubernetes organizes containers into logical clusters. Kubernetes is capable of running in both cloud and on-premise systems, as well as hybrid clouds.<\/span><\/p>\n<p><em><strong>&gt; <a href=\"https:\/\/gcloudvn.com\/en\/google-kubernetes-engine-gke\/\">Refer to the Google Kubernetes Engine (GKE) system<\/a><\/strong><\/em><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"So_sanh_cac_diem_khac_biet_giua_OpenShift_va_Kubernetes\"><\/span><b>Compare the differences between OpenShift and Kubernetes<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400;\">Now that we have some basic knowledge of OpenShift and Kubernetes, let&#039;s take a look at some of the differences between these platforms with Gimasys in the table below.<\/span><\/p>\n<table>\n<tbody>\n<tr>\n<td><strong>OpenShift<\/strong><\/td>\n<td><strong>Kubernetes<\/strong><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">OpenShift is not open source.

While K8 helps automate application deployment, scaling, and operations, OpenShift is a container platform that works with Kubernetes to improve application performance. If you are familiar with containerization ideas and have some knowledge of K8s, then you may prefer Kubernetes over OpenShift because it is more flexible. OpenShift makes things easier for newbies by providing a better CLI and of course a web interface. Beginners should use the web interface instead of the command line interface. On the other hand, the console with K8 is not ideal because it doesn&#039;t add any value to K8 other than the command line.
