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 templates in the form of text files that can be treated like code. This workshop provides a thorough understanding of Heat Orchestration Templates (HOT). Using an OpenStack system, students will 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.

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 Heat Orchestration Templates
• Create heat stacks in an OpenStack deployment
• Create nested heat templates
• Articulate the Affects of Global Enviroments as they relate to launching Heat Stacks.
• Practice the scripting of VM actions & configuration at boot time.
• Identify the IaaS requirements & VM Image requirements to support advanced Orchestration techniques.
