Ismertető
This course covers the fundamentals of the Openstack open source IAAS (Infrastructure As A Service) cloud solution, used for creating private clouds. After a short cloud and Openstack primer, it presents the architecture of Openstack and introduces its base components in details such as the Horizon GUI dashboard and the Openstack CLI, the Keystone identity system, the Nova compute service, the Neutron network service and software defined networking, the Glance image service, the Cinder block storage service, the Ceilometer metering solution, the Heat orchestration services and the Swift object store. Structure: 50% theory 50% hands on lab exercises.
