This short course covers the fundamentals of the Openstack IAAS (Infrastructure As A Service) solution used for creating a private cloud. It starts with a general cloud primer and the main cloud types ( IAAS - Infrastructure As A Service, PAAS - Platform As A Service, SAAS – Software As A Service) continuing with the origin and main features of Openstack, its architecture and core building blocks. An important part of the training is the demonstration of the basic features and operation of an Openstack system.
