Kubernetes is an open-source container orchestration tool that automates the deployment, scaling, and management of containerized applications, making it a crucial component for businesses adopting cloud-native technologies. It provides a consistent and portable platform, allowing teams to manage applications across various cloud environments without tailoring them to specific providers. Key features of Kubernetes include automated deployment and updates, automatic scaling, self-healing, and efficient release management, which collectively enhance the resilience and efficiency of operations. Kubernetes' robust ecosystem supports Agile development practices and CI/CD processes, offering extensive support for applications' quality and reliability. Unlike Docker, which focuses on building, distributing, and running containers, Kubernetes manages and orchestrates these containers across multiple nodes, thus excelling in scalability and application management. Its technical architecture consists of nodes and clusters, with a control plane and worker nodes to manage and run containers, respectively. By streamlining the deployment and management of containerized applications, Kubernetes has become an essential tool in modern DevOps practices.
