OST104 - OpenStack Administration

This course covers the fundamentals and basic administration of the Openstack open source IAAS (Infrastructure As A Service) cloud solution, widely used at private and public clouds. After a short cloud and OpenStack primer, it presents the architecture of OpenS tack and introduces its base components in details such as the Horizon GUI dashboard and the Openstack CLI, the Keystone identity system, the Glance image service, the Cinder block storage service, the Nova compute service, the Neutron network service and software defined networking (SDN), the OpenStack Telemetry solution, the Heat orchestration services and the Swift object store.

Besides in-depth theoretical coverage students also do hands-on exercises with all OpenStack components studied in their own OpenAtack lab system.

Structure: 50% theory 50% hands-on lab exercises

Target audience: Developers, SysAdmins, and DevOps wanting to obtain working knowledge about the OpenStack open source cloud system.

Certification: This course prepares participants for certification. The Certified OpenStack Administrator (COA) certification is the only sponsored certification by the OpenStack Foundation.

Guru Labs is partnered with Component Soft an OpenStack Training Partner for OpenStack courses and certification preparation.

Prerequisites:

Basic Linux systems administration (GL250), networking, as well as virtualization knowledge.
