Notes

IaaS and PaaS

  • IaaS delivers on-demand infrastructure resources vis the cloud, it provide raw compute, storage, and network capabilities, organized virtually into resources that are similar to physical data centers.
    • Compute Engine is an example of a Google Cloud IaaS service
    • Pay for what they allocate
  • PaaS delivers and manages all the hardware and software through the cloud, it bind code to libraries that provide access to the infrasctructure application needs
    • App Engine is an example of a Google Cloud PaaS service
    • Pay for what they use

Resources Hierarchies (4 levels):

  • Resoruces
    • IDs are immutable, names are mutable, project number is for Google Cloud's use
  • Projects
    • can contain subfolders
  • Folders
    • can group projects on a per-department basis
  • Organization Node

Policies are defined at the project, folder, and organization node levels. Policies are inherited downwards

IAM roles

    • Owner, Viewer, Editor, Billing Admin
  • Predefined IAM role

Compute Engine Pricing

  • Sustained-use (discount starts after 25% of a month)
  • committed-use (57% discount)
  • preemptible & spot VMs (jobs can be terminated and rescheduled by cloud. can save up to 90%)

Compute Engine Storage Options

  • Zonal persistent disk
  • Regional presistent disk
  • Local SSD: high performance, transient
