OST104 - OpenStack Private Cloud Administration

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, students will learn the architecture of OpenStack. This course introduces base components in detail such as the Horizon GUI dashboard and the OpenStack CLI. Other components learned are 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

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, and virtualization.
