Rancher is a powerful open-source platform designed to manage and orchestrate containers in a cloud environment. It simplifies the deployment and scaling of applications by providing a user-friendly interface for managing Kubernetes clusters. With Rancher, users can easily create, monitor, and maintain their containerized applications across multiple environments, whether on-premises or in the cloud. One of the key features of Rancher is its ability to support multiple Kubernetes clusters, allowing organizations to manage different environments from a single dashboard. This flexibility makes it easier for teams to collaborate and streamline their development processes, ultimately leading to faster and more efficient application delivery.
