Fundamentals of OpenStack Technology

This course teaches administrators and users to configure, manage and use the OpenStack® cloud services platform. An architectural overview ensures understanding of various OpenStack projects and their functions. Hands-on labs provide configuration and operations experience with major aspects of the OpenStack environment. Course content and labs are based on the OpenStack Rocky release.

After you successfully complete this course, expect to be able to:

• Describe the purpose and features of OpenStack
• Describe its high level architecture and list its major components
• Describe methods of access to OpenStack services
• Gain basic hands-on experience

System administrators, engineers and consultants who plan and manage OpenStack-based environments.
