The document discusses the advantages of deploying Kubernetes on bare metal, emphasizing its efficiency over traditional virtualization methods. It highlights the use of tools like conjure-up, juju, and maas for provisioning and managing Kubernetes installations. The author mentions the significant impact of Kubernetes on cloud-native methodologies, suggesting it represents a major shift in technology for the coming decade.

➢ Ultra fast “vm-lite” guests (bare metal speed)
➢ Any distribution of Linux - e.g. Ubuntu, CentOS
➢ Starts in less than 1 second
➢ 15x density of KVM or ESX for idle workloads
