OS100 Rocky

UPDATE!  The OpenStack Bootcamp I (OS100) is now updated for the Rocky release.

This course provides a complete preparation for the OpenStack Certified Administrator (COA) exam.

The OS100 bundle is intended for IT Operations Engineers, Network Admins, Security & Storage Architects responsible for design and support/ operation of OpenStack installations. The course provides participants with a detailed understanding of all of the steps necessary to operate an OpenStack environment.

The lectures provide students with an overview of OpenStack and its Architecture, OpenStack Networking, and Orchestration using Heat templates, including integration with Telemetry services.

The labs provide hands-on experience in an all-inone OpenStack environment. Students will be given opportunities to use and administer OpenStack using the Dashboard UI (Horizon) and the command line. Each lecture is followed by a series of lab exercises. During the lab exercises, students get to practice and engage with all core components of OpenStack. The labs conclude with a comprehensive review to solidify the hands-on skills that are required to operate an OpenStack environment.

The certification exam tests candidates’ ability to create, configure, and manage OpenStack. 

• Average required time to pass the course: 3 days
