Helm
Helm is a tool that helps software teams manage and deploy applications to cloud platforms, especially Kubernetes. Think of it like a package manager for cloud software - similar to how a recipe helps you consistently prepare a meal, Helm helps developers consistently set up and manage applications in the cloud. It saves time by allowing teams to use pre-made templates (called charts) instead of writing everything from scratch. This is particularly important for companies using cloud technologies and container-based systems.
