OpenStack is a very popular open source cloud enablement system for creating private and public clouds. OpenStack software controls large pools of compute, storage, and networking resources in the cloud deployment. Heat is the service for orchestrating resources in an OpenStack deployment. It implements an orchestration engine to launch multiple composite cloud applications based on YAML or JSON templates. This workshop provides a thorough understanding of Heat Orchestration Templates (HOT). Using an OpenStack system, students will develop, enhance and analyze several heat templates of increasing complexity that will work together to understand and apply heat templates simulating practical deployments of OpenStack in a Telco environment.

Required Equipment
• Students will need a laptop with a web browser and Windows Remote Desktop installed
• It is recommended for the students to use an additional monitor

This session is intended for team members in technology organizations who want to work with OpenStack Heat and create and use Heat Templates (YAML format) for orchestration.

After completing this course, the student will be able to:
• Read and interpret Heat Orchestration Templates (HOT)
• Design and develop Heat Orchestration Templates
• Analyze, enhance and validate outcomes of HOT templates
• Create Heat Stacks in an OpenStack deployment
• Create nested Heat templates
• Articulate the affects of global environments as they relate to launching Heat Stacks
• Practice the scripting of VM actions and configuration at boot time
