3. 3. Agenda HEAT Introduction Multi Cloud Orchestration Workflow TOSCA Heat Features Supporting Multi Cloud Orchestration Heat Architecture Resource Plugin Structure Standalone Heat deployment Context Centralized template repository with indexing and search New features in Kilo Release
4. 4. Heat Introduction 4 Heat provides a mechanism for Orchestrating Openstack resources through the use of modular templates It provides advanced functionality such as instance high availability, instance auto scaling, Software deployment and nested stacks
5. 5. Evolution of Heat 5 Havana Native template language (HOT) Concurrent resource operations Improved support to Networking, Ceilometer, Keystone trust Update/Suspend/resume Stack Icehouse Support for all native Openstack resources Software Configurations Autoscaling resources Notifications and File inclusions Stack abandon/adopt/preview Juno Recovery from failures during stack updates API to cancel and roll back an in -progress stack update Remember the previously-supplied parameters when updating a stack Improved scalability Improved visibility into trees of nested stacks Kilo Improved scaling using nested stacks oslo versioned objects Multi region stacks Stack lifecycle scheduler hints Software-config improvements

8. 8. TOSCA - Topology and Orchestration Specification for Cloud Applications 8 TOSCA specification provides a language to describe service components and their relationships using a service topology TOSCA enhances the portability and management of cloud applications and services across their lifecycle Enables Smoother migration of existing applications to the cloud Enables dynamic, multi-cloud provider applications Flexible bursting (consumer choice) TOSCA is OASIS Standard
