  2. Infrastructure as a Service (IaaS) • Infrastructure as a Service

    (IaaS) is a cloud service model that provides on-demand physical and virtual computing resources, storage, network, firewall, and load balancers. • To provide virtual computing resources, IaaS uses hypervisors, such as Xen, KVM, VMware ESXi, Hyper-V, or Nitro. • Infrastructure as a Service is the backbone of all other cloud services, providing computing resources. After the provisioning of the computing resources, other services are setup on top.

  24. Notes • The edX course you can find on the

    “Resources” section provides basic examples on video of how to run an instance in each one of the different platforms. Something interesting if you do not have experience with cloud based services.
