Virtualization and containers
0 likes37 views
The document discusses virtualization, containers, and Kubernetes. It begins with an introduction of the presenter Douglas Landgraf and his background. It then covers reasons for using virtualization like server consolidation. Examples of virtualization technologies like KVM/Qemu and oVirt are provided. Containers are introduced as lighter weight than virtual machines for isolated applications and services. Kubernetes is discussed as an open source platform for automating deployment, scaling, and operations of containerized applications. The document ends with suggestions for learning more about these topics through documentation, videos, books and conferences.
