It monitors your container workloads and ensures they run efficiently across multiple machines. It automates scaling and provides a reliable control system that keeps your applications running smoothly.&nbsp;<\/p>\n\n\n\n<p>Key points:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Kubernetes scales your applications automatically across multiple servers.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It keeps your containers running reliably, even when nodes fail.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It works with popular container runtimes such as <a href=\"https:\/\/contabo.com\/blog\/docker-explained\/\" target=\"_blank\" rel=\"noreferrer noopener\">Docker<\/a> or containerd.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li>It manages both small test setups and large production environments.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-are-containerized-applications\">What are Containerized Applications\u00a0<\/h2>\n\n\n\n<p>A <a href=\"https:\/\/contabo.com\/blog\/introduction-to-containerization\/\" target=\"_blank\" rel=\"noreferrer noopener\">containerized<\/a> application is software packaged with all required libraries and configuration files.
