Cloud Computing

Definition of cloud computing, ways to scale performance (clustering, virtualization), CPU/memory/I/O virtualization, how HPC, HTC, grid and cloud relate, three key issues in data center operation

Three Rocky Linux VMs on an M3 Mac with UTM nested virtualization + KVM/libvirt: static IPs, GRUB_TIMEOUT=0, virt-clone cloning, /etc/hosts, ping, SSH key authentication, fixing the nested-virtualization boot hang (pci=nomsi)

Building an HTCondor cluster on 3 Rocky Linux VMs (central manager, submit, execute), submitting 7 kinds of jobs with jds files, fixing the HTCondor 25.x multi-queue error and aarch64 requirements, exercises from Chapters 2–6 (multitenancy, SSH, public keys, slots, GPG, DAGMan, etc.)
