Openstack: Heat

Description

Heat is OpenStack's orchestration service. It implements an orchestration engine to launch cloud applications as text files that can be treated as code. Heat templates describe the infrastructure of a cloud application in a text file encoded by the infrastructure and / or development teams. This training is for people who want to implement the DevOps culture through a coded infrastructure. At the end of this training, you will be able to code your infrastructures based on the main OpenStack services.
