Cloud computing - Coggle Diagram

- - - - relate to the speed of storage; how quickly data can be read from or written to the storage
      - Pros: Faster speed of underlying disk
        low IOPS => bottleneck;
      - Cons: Higher costs
    - - persist: data are preserved; ephemeral: data are deleted;
      - what happens to the storage once attached compute node is terminated
- - - - Bare-metal
        
        HV is installed directly on top of the physical server
        
        most frequently used; most secure; lower latency
        
        e.g. VMware, ESXi, Microsoft Hyper-V, KVM
      - Hosted
        
        layer of host OS sits between physical server and hypervisor
        
        less frequent; most frequently used for end-user virtualization;
        
        higher latency than Bare-metal
        
        e.g. Oracle, VirtualBox, VMware workstation;
