It does not create containers but manages them. The core of Kubernetes is the <a href=\"https:\/\/firstcolo.net\/en\/glossary\/hypervisor\/\">hypervisor<\/a>, which acts as a layer between hardware and containers.  <\/p><p>The K8s architecture consists of various units:<\/p><p><strong>Container<\/strong>: Contains applications and their necessary environments.<br><strong>Pod<\/strong>: This unit groups containers that need to work together.<br><strong>Node<\/strong>: These virtual or physical machines run the pods.<br><strong>Cluster<\/strong>: A cluster consists of multiple nodes.<\/p><p>The <strong>Kubernetes master<\/strong> (a <a href=\"https:\/\/firstcolo.net\/en\/glossary\/servers\/\">server<\/a>) manages the system. It monitors the nodes, distributes the pods, and automatically adjusts the system state as needed. The master acts as a control center and enables administrators to orchestrate the containers. Each node, also called a &#8220;slave,&#8221; communicates with the master via Kubelet. The Kubelet starts and stops containers and records resource usage. This facilitates analysis and <a href=\"https:\/\/firstcolo.net\/en\/glossary\/load-balancing\/\">load balancing<\/a> in the system.     <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1afdabe7 elementor-widget elementor-widget-heading\" data-id=\"1afdabe7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Application and Benefits<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-796e832 elementor-widget elementor-widget-text-editor\" data-id=\"796e832\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Kubernetes holds a prominent position in software development, especially in agile projects. This is primarily because it simplifies the cycle of development, testing, and <a href=\"https:\/\/firstcolo.net\/en\/glossary\/deployment\/\">deployment<\/a> by automating many processes. Another key advantage is <a href=\"https:\/\/firstcolo.net\/en\/glossary\/scalability\/\">scalability<\/a>: K8s optimizes resource utilization and thereby reduces costs. When needed, Kubernetes can also automatically provision additional resources to handle high demand.   <\/p><p>Another advantage is the ability to use Kubernetes in <a href=\"https:\/\/firstcolo.net\/en\/glossary\/hybrid-cloud\/\">hybrid cloud<\/a> environments. This allows part of the infrastructure to be operated locally and another part in the cloud. This flexibility further enhances scalability. Kubernetes also provides clear visibility and version control. Developers can track the status of each container and roll out updates without downtime.    <\/p><p>Overall, Kubernetes is considered a reliable and secure system. It reduces the risk of failures, as the master automatically responds to problems and stabilizes systems. Kubernetes is therefore a central tool in modern IT infrastructure.  <\/p><p>With the management platform <a href=\"https:\/\/firstcolo.net\/en\/service\/firstkube\/\">firstkube<\/a>, firstcolo simplifies the use of Kubernetes at every touchpoint. firstkube includes a dashboard and orchestration service for the automatic provisioning and management of K8s clusters and associated cloud-native applications. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-130f4c00 e-con-full e-flex e-con e-child\" data-id=\"130f4c00\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-32b84e2e elementor-widget elementor-widget-button\" data-id=\"32b84e2e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Homepage<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-610cce4a elementor-widget elementor-widget-button\" data-id=\"610cce4a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/firstcolo.net\/en\/knowledge\/glossary\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Glossary<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>What is Kubernetes?
